I had a P0171 in my 2005 Corolla I recently bought for my teenager. 183k miles and no maintenance history but fairly good deal. Hesitation when takin off and when accelerating and very high fuel trims with bad gas mileage (20 mpg) Ended up doing all sorts of things attempting to fix it. Watched tons of videos and even took it to mechanic to diagnose. Cleaned MAF sensor, “TESTED” MAF sensor using the unplug while idling method and car shut off so I concluded MAF was good, replaced PCV valve, air filter (very dirty), oil and filter and changed spark plugs…no change. Took it to mechanic $100 diagnostic fee who quoted me $2100 to replace the breather hose ($220 ) cat converter (1300+) and induction service all of which I declined. 2nd mechanic recommended replacing intake manifold gasket….I started working on it myself…bought cheap OBDII scanner and cleared codes after each intervention then tested. I replaced intake manifold gasket, throttle body gasket, Removed and cleaned fuel injectors using popular DIY method (9v battery and can of throttle body cleaner, replaced intake hose, breather hose, new ignition coils (just because), ordered BG 44k Platinum fuel system cleaner and used EPR, MOA in crank case, new oil and filter of course finally replaced fuel pump…to my dismay, no change. I watched this a figured what the heck I guess I’ll try a new MAF for $40 from 1A Auto…. Fixed it. No more codes, normal fuel trims, drives very well. So the “unplug the MAF and engine shuts off” test commonly seen on KZbin is NOT full proof. Hopefully this helps someone! I’m no mechanic but I learned quite a bit and actually enjoyed working on this car. Now to change transmission and other fluids.

My 05 matrix won’t die. Over 315,000 miles and still going strong (odometer stopped at 299,999). Tons of gravel road use, and I’ve drove it from Kansas to Washington six times. I’ve clipped three deer in it going moderate speeds and still is chugging along. I use it as my main fishing vehicle as it easily transports two labradors retrievers, 18 gallon tote for lures, 55 quart cooler, deflated float tube, waders, and 4 fishing rods sticking out the passenger rear window. All seats are laid over and pads laid out for the dogs. I’m 6’3” and the only thing I have to remove for me to car camp is my fishing rods. A totally practical vehicle for outdoor pursuits, just have to watch the ground clearance. I’ve put 10,000 miles on it fishing spring of 2020 just so you get the picture of the abuse it’s put through.

[@j.chenmuas]

Dang thats awesome, always wanted a matrix and thanks for sharing how amazing your car is and for lasting that long. I may have to sell my 07 outback or possible trade for a matrix. Its amazing to hear what this car is capable of. My outback is alright but I'm not fond of how the motor is built, its complicated. I do enjoy fishing too and use my outback for that purpose. 👊

[@garragol1]

Just got a 06' and im using it to do door dash, it came with 266k miles 😁

[@andresnunez576]

Over 330,000 miles on my 03 matrix (also stopped at 299,999 ) and I'm debating if I should fix the window falling problem. I've gone so long with out being able to roll down the passenger window because of this issue. How exactly much longer do you think the car will last ? I rather not throw much money into it with so many miles.

[@PaulRudd1941]

Good to know the American models stop at 300k miles, mine is a canadian model and it stopped at 300k km or about 186k miles. I love my Pontiac vibe to death. Best car I've ever owned. My brother has 2 and my sister has 1 as well. We're the hatchback pack 😎

[@Starmanbike]

I own two 2004 matrix cars. One has 244,000 miles and the other is the 4wheel version with 160,000 miles, no real issues and love them both.

[@yeraskid]

Best car relliable, comfortable, 1.8!, Great milleage, parts unexpensive, no cvt, power stering (no electronic!), 18 years and go strong.

[@Smileyguy-jy6xm]

Great cars IMHO. Nice tip about tightening the window screws. I have 06 Vibe with same engine 93k miles. I noticed a loss of power and gas mileage. I found the intake manifold gasket was leaking. About $10 and 1 hour to fix. Gained 5 mpg and power return after fix. Also had a small leak in valve cover gasket letting a bit of oil seep down to spark plug, again about $10 and 1 hour. Worst thing I've had was replacing tensioner pulley. A bit more $$$ and work but still doable for a DIYer. These rides are pretty easy to work on even for a noob like me, super reliable and run forever. Love mine.

[@patrickzambori473]

You forgot the cloudy headlight shells, the odometer that hangs up at 299,999, door handles breaking off and door stays snapping.... Minor stuff, great cars.

[@1AAuto]

+Patrick Zambori Thanks for the feedback!

[@Jsmithlovesspam]

That door handle replacement is no joke though, as an amateur moving the locking mechanism out of the way was a little intimidating, and latching the handle improperly might cause one to have to re-do most of it…not that I did that or anything

I have an 2005 Toyota Matrix as well with just over 200,000 miles. Good reliable commuter vehicle like you said. Just have one quick question regarding rust and paint fading. Just curious if your roof is starting or has already started to rust like mine along with the paint peeling on the hood like mine. Have been researching this and supposedly in Toyota blogs I have been reading through the 2000s model Toyota cars were not equipped with the proper rust/oxidation prevention coat when originally manufactured. This problem has not only occurred in the matrix models also other 2000s Toyota models. While searching this on google I’ve noticed I’m not the only one that this has happened to especially on Toyota Matrix models like ours. Hopefully this issue/defect has not occurred on your car. If so just curious as to how you went about repairing/fixing it. Been researching and trying to find a low cost method to fix my car. Any input/info you can offer is appreciated. Thanks.

[@JFP9036]

@@Jeepguy30022 i have a 05 matrix, sane problem with paint not so much rust. As far as problems in video, knock on wood i haven't had any of those in vid. Only have 125,500 miles, just had new clutch, ac compressor and struts done. Love the car but looks rough on outside for sure. Going to paint. Need to have all door handles replaced,all cracked in half and hatch/window arms replaced.

[@Wisco_sin]

Had a 6-speed Black Vibe that I loved so much!!! It was my second vibe, but first manual. Went through some hard times during the pandemic and sold it for way too cheap because I needed money. I have another vibe but I will forever be missing my manual 6-speed black beauty..

[@sppooon4755]

My family had a 07 matrix and nothing had gone bad with it or broken down on us besides our muffler getting a bit lose. One day in 2019 we where driving north on a highway, going about 110km (about 70mh) and the hood latch just snapped, middle of the highway the hood came flying up at us and destroyed the windshield and dented the frame. No one was harmed. The car was towed and was deemed totalled. Now 4 years later im 17 with my G2 and im looking for a Camry, Corolla and hopefully a Matrix.

[@Ogsonofgroo]

I inherited my father's 2007 Vibe when he passed in 2017 (RIP Pops), it was his second one after he got t-boned in the first. He chose well and its been an awesome vehicle thus far, tonnes of capacity, great mileage, reliable, the little Kenwood/Monsoon stereo system rocks enough I don't need more, it gets regular oil changes and thats been about it so far (other that brakes etc.). The engine light just appeared for the first time so I'll get somebody to read the code, but the running doesn't seem abnormal and I'm hoping its something simple like a new air-filter or MAF or O2sensor. I'll disconnect the battery for a bit and reset the brains first and see if it persists. Thanks for the video and to the other commentators for their input, really good cars imho :)

[@gregburrows4192]

From one car guy to another who is about to go out and see one of these, THANK YOU!

[@Richard-pu9rg]

The window regulators/weather stripping are a big one too. I've had to replace them on both my mother's 2003 Toyota matrix's as well as my recently obtained 2005. The window regulator will eventually guide the window up out of place and fold/wedge the weather stripping out of place destroying it and the regulator. These often need replaced I've noticed.

[@albertluker3032]

My vibe is at 325k and runs perfectly on the original engine and trans. I’m the only person that works on it. Wife is jealous of the car. Says I think about it more than us! I use it now just to drive from GA to Ohio to visit my son. I won’t hesitate to put 1,200 miles on it once a month over a long weekend. I leave the new 2018 Honda CRV and 2021 Toyota Tacoma at home. When the Honda is in the shop we have a standby that ALWAYS runs. It shows that proper care will keep it going nearly forever. I see making it to 500k easy.

[@felixanineh5997]

I have a Toyota Matrix 2005. I have had my driver seat glass drop and also an issue with my catalytic converter. This was insightful 💪🏼

[@Gravertrain]

Thanks for the vid. I own a 2008 Pontiac Vibe with 240K miles. Bought new, oil every 3k, religiously. Never had a spark plug out. Only issues were recalled air bag and computer module. I replaced a heater door actuator and an intermediate exhaust pipe. Most trouble free car for me, ever. No Wisconsin rust and the engine runs and sounds like new. Never used a drop of oil and the oil looks almost new at the 3K oil changes. Normal brakes and tire replacement.

[@MarzNet256]

You should replace the plugs with denso iridiums, the gap is increased at this mileage and it puts a lot of strain on the coils to jump the larger gap. Additionally, the plugs can sieze up in the head if left too long (make sure you change them on an ice cold engine, to avoid damaging alum threads in head).

[@TheFoureigner]

I have an 03 with 270k miles and it has 3 of these problems recently, great video.

[@jacobandstephaniethompson9658]

Thank you for the professionalism and clean language!

[@MR2trader]

I'm over 350K on my 05 Matrix and his problem list is spot on. I'm going to need to locate the bad engine mount when I change my clutch in a few months. It's eaten a lot of coils and i can't get the exhaust sealed up at the headpipe but other than that, it's been a great machine.

[@1AAuto]

+Tom Cyr Thanks for the feedback!

[@stevenpadilla7200]

I recommend replacing all your engine mounts

[@Tempsho]

My 2003 xrs has the same exhaust leak at the donut from the down pipe. I hope I can get it to seal

[@aartmark]

You're right about the mass airflow sensor. My Matrix had less than 60,000 on it when I had problems with it. I tried to clean it with the MAS cleaner but like you said it was too dirty. They are really easy to take out and replace. You have to trade in your old one for the new one plus about $70. The car will run really rough and I think the check engine light or something came on when it went bad. It was a long time ago. Another problem of course is the passenger side airbag recall. The first recall they replace it with the same bad airbag and then sent out letters a few years later to replace that one. I had a real hastle trying to get the dealerships to get the correct parts and do the job. I finally got it done and what a relief.

[@truckericksdashcam]

Our Pontiac Vibe original battery lasted 17 years . I did the first spark plug change at 308500 kilometers .These car are great . I did have to replace the drivers side door stop 5 times . My wife says the wind ripped it out of her hand . 🤔

[@mumm-ratheeverliving3138]

Had most of those and a few serious issues with my ‘05 AWD. The rear VSC went out a about 90k miles and the unit was over $4500 to replace. No way I was going to pay for that. I ended up cutting out the rear drivetrain and JB welding the yoke on the output shaft. It’s got 200k miles on it now, and the repair has held up so far. Also, the airbag system on mine is temperamental. Replaced $1400 worth of parts and harnesses and it still acts up. I’m sure the FWD models are fine, but I’d stay away from the AWD version.

[@Meenadevidasi]

WOW!!! Super!! 2003, Still "smells" like a new car. Fantastic vehicle. Over 200,000 going strong. We've got engine light,,, will check the code, and the window thing. thank you

There has been a problem with leaking timing chain covers which if leaking oil a lot requires the engine to be removed which is expensive. It’s too big a job for me but thought owners and potential buyers should be aware. It may have been covered by Toyota at some point if car was taken in. Thanks, good information about the evap code.

[@brettsuydam7457]

My wife drives a vibe(GM version) and it's been solid. It will hit 200K at the next oil change and we've put over 100K on it. Only thing I've had to do beyond regular maintenance is the charcoal canister, intake gasket, exhaust header, serpentine belt tensioner, and an upstream oxygen sensor. All very easy to do at home.

How many miles do you have on her?

[@wendyphillips5002]

I have over 201.000 miles on my Toyota 2007 Matrix. Have not had any of this issues with my car yet. Thanks for the information and help on how to deal with these issues. However, changed my up and down stream O2 sensors, outlet manifold, water pump, thermostat, alternator, drive belt and tension er. Wow, to replace that drive belt tension er you have to disconnect that front right motor mount jacking up the engine by 4 or more inches. That bottom alternator bolt is hard to remove. Don't strip that bolt. Pay attention to the torque specks on those 6 water pump bolts they are not all the same. Maintenance, maintenance, and maintenance is the key to keeping your Toyota Matrix running for a long time. Get a OBD 2 reader and it will tell you what your problem(s) are when the check engine light comes on. It is like the Air Force B 52s. They are from 1955 and still in the air. It is maintenance. The only original part of that plane may be the original tag on the frame. Everything else has been removed and replaced maybe several times or more. It has been flying for nearly 67 years.

[@tavencio]

Hello, I liked your video, I have a 2008 Toyota Matrix, it is a good car, despite some of these details that have happened to it, it has 140,000 km and the engine feels very good. Greetings from Mexico City

[@jaym7494]

What issues have you experienced and what did you do? I also have a 2008 Matrix, mine is a base model with 5 speed manual. Runs great, I'm very happy with it. I proactively changed the intake gasket to the red one. I got the dealer to order the part in for $12 CAD and then I installed it myself following a KZbin video. I also cleaned my MAF sensor with MAF Sensor Cleaner spray, and the only other thing I did was get Toyota the dealer to replace my airbag(s) under recall. It's good to take advantage of free service under recalls now since they are only valid for 15 years and our cars are 13 years old.

[@cheannbal]

2003 Matrix automatic that I'm still driving. I love this car and hope it lasts me until I no longer need a car. :D The only thing I HATE is that they didn't carpet the floor of the hatchback. I put a big rummer mat over is to stop gear from sliding around. In 20 years I have replaced the battery, muffler, starter motor, and various gaskets. My cousin owns the garage I take it to and he says if everyone bought a Matrix, he'd be in the poorhouse.

[@minivantripping2007]

I had a 2007 Pontiac Vibe and was so impressed by its performance and dependably! Mechanically it’s the same as the Matrix. The exterior is the only difference between the two. I’m looking to buy a new one because they run forever! I know someone that has got one that has well over 200,000 miles on it and it is still running strong! My only other choice is a Honda C-rv. It’s known for its dependability as well. But that’s it. I don’t want anything else.

[@user-kq5xr6gu1s]

19 years old Toyota Matrix. The same problems like engine mounts (vibration) and the O2 sensor. No more problems with this car. It is the best car for it's years. Greetings from Ukraine! :)

I own an 06 matrix it has 316000 and I had all these issues and then some . I had a p0171 and it actually ended up being the intake manifold gasket . That gasket was so brittle I was shocked but , easy fix none the less .

[@gloria7324]

I've seen most of these issues with my 2006 Matrix. Bought it cheap (used of course) a couple years ago because that's all I could really afford. And it's just been one thing after another. I'm not very mechanically inclined, so I've had to outsource. And just recently took it in for the airbag recall and they gave me a long list of things it needs addressing with the fluids, the brakes (which had recently started squealing). Someone tried to break into my car, so I had to get a window fixed, still debating whether I should order new locks since these got messed up. Oh, and my kid snapped one of the handles off. But aside from all that, it gets us where we need and is still going strong on all the miles. Just gotta set aside time (soon) to get all these issues finally addressed.

[@collinsje5]

'06 Matrix XR here bought new 2005. 19 years old in September. 73K original miles. I have had none of these 5 problems, but I live in Chicago, so needed new exhaust in 2022 and extensive front end work in 2023 (city streets are brutal). 1800cc engine with auto trans. My mother calls it Wonder Car. I am always getting approached by parking garage managers that want to buy it. Nuh-uh. The car gods blessed me with the Matrix as compensation for having bought a Chevrolet Vega back when.

[@jonnyenough1531]

I have my 05 VIBE GT, love that car and it's over 600k miles.. Only issues consistent is the sunroof leaking, stereo having to be reset. Preventive maintenance is key. Right now I replaced the clutch but normal wear. Then the big one is the valve that blows through the exhaust on shut off

[@jhb9254]

I've owned a 2004 5spd since new. I've only had to replace a couple ring seals, intake gasket and lately one of the transmission bearings. The shocks are next. All original bulbs and such are still working. Aside from routine fluids and drive belt, nothing else has needed replacement.

[@xlnbxindianboi]

How many miles do you have on it?

[@MrMOGHammer]

@@skylilly1 yes there is 2 catalytic converters but actually act as one with the o2 sensor in between.if it's the back one that is bad no codes would be triggered since it is passed the downstream o2 sensor. If the back one is bad the other one might be bad and that throws a code. They usually come together in one assembly

[@MrMOGHammer]

@@skylilly1 the ticking noise could be the evap thingy under the hood that ticks

[@L35inColorado]

I love the Matrix! I have an '06 that I bought for $700 two year ago; the price was cheap because it wouldn't run (blown head gasket). I spent about $300 on parts doing the head gasket (all the gaskets and seals I could, plus rod bearings and everything else I touched during the job); the head had to be milled 10 thou, but the block didn't warp (aluminum block...I was afraid it would have warped, but it didn't). So my Matrix has a milled head, haha! The reason the head gasket blew in the first place was because apparently some mechanic forgot to plug in the fan electrical connector and it overheated. It was sitting for almost a year before I bought it. She now has 215k miles (20k miles since the rebuild) and is going strong! I recently drove her on a 3000 mile road trip, and had no issues at all. I wouldn't think twice about driving that Matrix from Maine to Los Angeles. Just keep up on oil changes and fluids, and they are great vehicles. The one item I'd add to your list is the exhaust pipe at the muffler flange always rusts out on these and the Vibe and so you have to replace a piece of pipe from the resonator to that flange. Oh yeah, and the digital clock on the dash is hit or miss (bad soldering on some resistors inside). That's about it!

[@1AAuto]

+L35 in Colorado Thanks for the feedback, we appreciate it!

[@irfannazir5671]

@L35 in Colorado these points are spot on. I have an 06 rolla and I am on a third piece of tail pipe that rusts every few years, lol. I recently re-flowed the solder in my clock and it is bright again. BTW you have good channel too. cheers.

[@Guitarsandmore]

Great Car. I have 260,000 miles on my 2006 Toyota Matrix XR. So far its been mostly tires and brakes, oil changes and oil filters, air filters. I changed the plugs once. Replaced the starter once. Replaced the battery a couple of times. I have had this car now for 14 years. It has the original engine and the original transmission, which, I think are holding up better than the body parts. A few body parts have just worn out and fallen off such as inner fenders, trim below the doors,. trim on the back end, the letters. I may have the motor mount issue because it is making some noise. But it is still getting 30 miles to the gallon, like the day I bought it. I wish I could buy another one.

[@1AAuto]

+Gary Amstutz Thanks for the feedback!

[@scenicdepictionsofchicagolife]

I think I have the bad MAF... but the only issues I get from that are cold start idle surging so I've not yet replaced it. The only other issue Ive had on the list is the window falling out, but that's because someone hit the passenger door in an accident (I was parked) and damaged the mechanism. As for the idling vibrations? The 1ZZ-FE is a very rattly engine - lots of NVH even in VINs with healthy engine mounts.

[@yogitam2372]

I have a 2006 Matrix XR, auto. Love it. Here are two downsides. I live in LA so when the temperature gets above 95, the AC starts to lose the battle. I have an excellent mechanic, we keep the ac charged up. Done everything we can to get the max AC but I just accept that the 06 model, the ac they use is just not that strong. Guy I know has an 09 Matrix but his ac is cold when the temp goes above 100 here. The other issue I had, at 60K, one of my engine mounts broke. Couldn't believe it. I am the second owner. I am an old guy so I am a safe driver and rarely ever speed. Previous owner was a senior who used the car to go grocery shopping before she retired to a nursing home. I bought the car at 40k. It is still going strong at 120K now.

Also put lower control arms on a few times due to worn out bushings

[@bobsoft]

Dim clock display caused by cold solder joints.

[@Alex35c]

The intake gaskets and manifolds are bad for leaking in cold weather throwing a p0171 code, as well as the timing chain tensioner o-rings fail causing an oil leak that makes the passenger side back of the engine and ps pump. Just a few common problems with the 1zzfe platform :)

[@MarzNet256]

P0420 code can also be caused by exhaust leak causing downstream 02 sensor to go lean. I had a leak at the donut gasket on exhaust Manifold.

@1A Auto: Repair Tips & Secrets Only Mechanics Know hey guys I really love your channel I’m 15 & I’ve been autocrossing a 2006 silver base Matrix since my 12th birthday I was wondering, I don’t want to waste your time, but that particular midnight blue Matrix you showed in this video, what year is it, & how many miles are on it? I’m curious. In a different video I saw it was a stick shift. The reason I’m asking is because since I love 1st Gen Matrixes so much (because of reliability & versatility), I just had to ask about it. Hope I’m not wasting your time. It’s okay if it takes you guys a while to reply, because I get it, you would have to find a time to walk through the dozens of video-purpose cars at your 1A auto lot in order to get to the Matrix, or if you even have it anymore (this video was 2 years ago)

[@haroldclark4485]

Only problem we've had is door handles - they break in half. Plenty of replacements on line, but getting them to work right is a chore. Warning: be careful replacing driver side front, could mess with smart/chip key. Otherwise I just can't think of any problem with these greatest of all cars!

[@Greg-io1ip]

Always hold loose glass all the way up and firmly flush to the top door frame. Tighten properly firm while holding in place. If you can't get to screws all the way up, you can get them firm but loose, push up into position, lower carefully then tighten fully, hold what you got.

[@formermpc10]

No mention of losing hubcaps? Great video, thank you.

[@skylilly1]

LOL Yes! I have an 03. I lost all of my hubcaps. It's kind of a running joke with these cars.

[@daniellecryderman2954]

@@skylilly1 my tip is to super glue the clips on the hubcaps. But they are just the best cars ever made in my opinion. Not like Chevys that break down on the side of the road

[@kevinspence6287]

That would be nice if y’all could make a video of a how to video on how to remove a transmission from 2003 matrix Xr manual and more

P0171 was triggered on my 2005 Pontiac vibe and it turned out to be dirty / clogged fuel injectors. No vacuum leaks present.

[@robertp9370]

I found a 2005 matrix with the same code. the owner says the car takes a while to shift after 65mph... fuel injectors? that solved your transmission issue?? Should I buy this 2005 matrix and try to do a tuneup on it? its got 188,000 miles

[@robertp9370]

she wants $1000 for the car

[@MrMOGHammer]

@@robertp9370 just fucking buy it. And fix it yourself. Shouldn't cost you too much. This is a great car to get and at 1000$ it's a bargain. Especially if it still looks good. Have a test drive first though, and pay attention to every detail. Like you should always do when buying used cars

[@WarriorsPhoto]

Thank you for sharing these with me. I was thinking at least one of these could be a concern on this car. I'll keep this video handy for if I ever get one of these codes or symptoms. Are you guys a tuning shop as well?

[@mark4347]

Good Video, but you and the vehicle are the stars of the show. Respectfully, please ditch the background chatter, err, music.

[@1AAuto]

+Mark Thanks for the tip! We'll pass this info along to our production team.

[@chuckconnors615]

I very much enjoy your videos. I have a suggestion: wear blue / yellow / pink gloves . anything other than BLACK! when you were pointing @ the motor mounts I your pointing finger got lost aginst the black items / the darkness of the engine bay... Thanks for all Y'all ( that is TEXAN for You All )

[@shonuffisthemaster]

manual transmissions have a falure prone bearing, also i had my power steering pump lines rust out and they are a big pain to replace

[@Bellathebear777]

Ez enough. Thank you. Theres a tsb on the intake manifold gasket. Get the Mahle orange one. Amazon sent me the felpro black gasket. I used it anyway. They appear the same. There not. It's worth doing yourself. It's pretty straight forward. Caution. The vacuum hose on the rear, needs to be put on the manifold , right after you slide it ( manifold) into place. Toyota nation has a write up. It's better done in the sun, than a garage with overhead lights. It can be done in under an hour complete. Don't use gasket adhesive

Whoa, manual windows? I didn't even know that was a thing. I have an 07 Corolla S, I figured all Corolla's just had power windows. HUH! I am surprised that belt tensioner pulleys never showed up on the list.

Hey thanks, got a p420, i guess good time to replace filters and plugs, cheack leads ect... Oh and a once in it's life time used car oil change.

[@debmnmn5054]

Have 08 matrix - had most of exhaust system replaced - p0420 code still coming on with check engine light - this video helps - my mechanics cannot figure out why the code is still coming on - going to try several of the tips to see if that helps.

[@JeffTiberend]

I got an ols 05 Matrix with alot of miles. The odomoeter quit reading. But, the suspension sucks. I even tried having new struts put on it.

[@MrMOGHammer]

Suspension on a matrix is geared towards sporty and not comfort. Kind of a compromise between the 2

[@viperomen914]

So that’s what’s causing the shaking on my car when every I stop at a red light or just a stop sign the car shakes a whole lot more then it used too so should I just get the mounts replaced?

[@tubergonz]

I have an 03 Vibe GT. Between the Vibe and the Matrix, they're both hatchback versions of the Corolla so reliability isn't a surprise. I've replaced the catalytic converter twice with universal ones (can't complain since they were cheap). I haven't really had to deal with any of the other issues listed but I suspect my mass air flow sensor is going bad. I have also replaced the clutch a couple of times. Honestly, the issues I'm dealing with right now are a small power steering leak and possibly an oil leak that sends fumes in through the a/c system.

[@RC44E]

Thanks I have the check engine light for the evap canister.

[@PinoystROngwoodworks]

I have a 2004 Toyota Matrix hatchback door won’t open but the window does. How can I get the trunk to release from the inside panel? Thanks for your time

I just came across an 04 matrix for basically free. Im so blessed right now. It's 126000 mi

[@Barneyrubble241]

The only reasonably expensive item is the Cats. Everything else is cheap and doable for most DIY guys. Looking at picking one of these up tomorrow if it seems like a good example. I need some cheap reliable transportation that I can put a ton of miles on.

[@therealmichaelphelps]

I’ve replaced the evap canister, and the evap valve at the front and tried multiple different kinds of gas caps, the evap codes keep coming back. Sometimes I hear the front valve clicking on and off again repeatedly and especially after I clear the codes, after it does that again the codes come back. Could it be a clog in the line as you said it needs vacuum?

[@davidtorres7817]

Hello I have a PO171 i changed mas all 3 02 sensors did a smoke test and still got the code what am I missing Thanks

[@tommysalami8400]

My grandma got this 2005 matrix with roll down windows and its got most likely around 400-500k on it put recently the motor is getting louder

[@gatesurfer]

I have a 2003. Basic model. Put nearly 100k on it in four years driving from Seattle to the Columbia Gorge about 15 times a year to windsurf, then only about 60k since having moved to Hawaii. I’ve run it so dry at time that it took more than three quarts of oil to fill it. I’ve had to replace brakes, battery, alternator and the AC is busted. Just recently had to replace the rear taillights because they were so faded they weren’t red enough for safety check. The rear tailgate latch is so rusted that it won’t lock. But the main thing is the hubcaps. I lost one, then two, then three and four all within about six years. I see matrixes all over with missing hubs, which cracks me up. I don’t care. It’s great having a junky car in Hawaii so no one breaks into it. I’m just trying to nurse it al9ng until the EV truck I’ve ordered is ready. I spent $13k to buy it new and maybe $3k since on various little repairs. Excellent mileage. Carries my surfing gear easy. It’s a great car and I’m upset they stopped making it. That fold down front seat is great. It folds down so flat that I can put my nine foot surfboard inside no problem.

The most common cause of EVAP codes is the vacuum switch valve on these Matrix and Corolla.

[@jeremyb456]

Yes mine is throwing a P0452 and we can't put gas in it without it clicking off all the time at the pump I am going to replace it this weekend. Is this problem because we can't put gas in it? Thanks

Good afternoon I have a 2006 toyota matrix it just develop a fault that if I start it, after a few seconds it will go off if I try starting it immediately it won't start but after some minutes before it will start again after some seconds it will go off again just like that. Please what could be fault and possible solution thanks

[@3rdworldtrillionaire46]

I have got none of these listed problems - weird. But I go have a roof that is starting to rust right at the windshield and of course mine has the well known issue, it's eating oil a lot. Granted I have 330000km on it. Other than that, the engines fires up reliable and no issues with the transmission. I'll keep it around as a beater.

[@DericCribbs]

Dude, that one is missing the rear sway bar! @3:10 Those don't just fall off, welcome to understeer city. I recomend disconnecting the front one instead. I have a spare rear sway bar if they need one🙌🤭. These cars are so easy to work on and one of the last available with a throttle cable, no abs or stability control and a super slick highly efficient manual transmission. I can burn the tires to the ground and not see any warning lights.
