I live in Nashville and I found an 08 All Wheel drive for an phenomenal price. It has a problem with the steering and brakes cut in and out, I think its a vacuum leak. It only does it when the car is at idle. When you are on the gas the problem vanishes. Any ideas on what it may be?

I have a 2011 cts 3.0. Owned from 46,000-98,000 miles. I’ve never had one check engine light or one single issue. I just did a coolant flush and transmission flush along with standard oil changes. Highly reliable vehicle at a great price and style.

[@stumpsteph2153]

Yeah that’s because you actually take care of your car😂 most people don’t realize they need to service other parts of the car other than the engine

[@Ghoststalker777]

The timing chain problem doesn't generally happen until the 100 to130km mark. I bought my 2010 CTS4 in 2018 with 151km on it and I was given the stealership invoice showing the timing chain was recently changed, I think it cost her around $2100 in all. The thing is you have to keep that oil changed. When I took it to my stealership they told me the first idiot owner never changed the oil for the first 15 thousand km and that's on a brand new car, the second time he changed it was around 12km. Thank god he sold it, I'm owner #3. I've had pretty much no issues except a new battery, front rotors and a door lock actuator in almost 5 years.

How many miles do you guys have on them? I have an 09 CTS with 113,000 and its perfect but im worried about the sealed transmission. I would like to change the fluid but I don't know if it is too old to change now . the manual says to change it at 100,000 miles but no one I took it too was willing to do it . I guess i should have taken it to the dealership but they rip you off in insulting ways. They want like $600 just to change the fluid.

[@hotakkord93]

@@MSG685 I'm up to 155k so far all good. Unfortunately i had to let the dealership rob me for the transmission fluid change. I've seen a few forums where guys are walking you through the steps to do it at home if you're into the DIY thing

[@MindRightLifeRight]

I have a 2008 CTS DI with 121k miles. Have not had any major problems since 54k miles when I bought with 54k. Alternator was replaced a while back, I did have some leaks from the timing chain cover, I had that leak from a dealer because I did not want to touch that not had the time to do it myself. I actually had a fuel leak but was able to fix it myself with like $40 bucks. Right now I have a low RPM idle and I think I need a new oil pressure sensor because it only reads 0 or 100🤔

[@DollnAbox]

Daniel Thomas I guess it all depends on the previous owner and how well they kept up with the maintenance. I have an 06 CTS, it runs like a dream. 71k miles, 1 previous owner (my dad), no major issues. When he gave me the car, it had 38k miles. He was retired, so it was driven very gently and infrequently. All fluids checked and topped off weekly, I never let the oil life get lower than 20%. I only use 93 gas, and I use a bottle of Gumout about every 6 months or so. She just had her first tune up about 6 months ago at around 67k miles, as I was having a misfire that triggered the engine light. That’s the only thing I’ve ever had really other than the sunroof being sticky sometimes, but I live in Florida, so it gets very hot and wet and makes rubber sticky. Once in a while if she sits in the rain for a long time or we have a Hurricane, it will idle rough for a few drives but always smoothes out. I bought a car cover for hurricanes since I unfortunately don’t have a garage. I have heard a lot of bad about these cars but in my experience they are very reliable if maintained properly. Most people ignore their cars and just drive until something goes wrong. My dad had a Jaguar S-type, which was a total lemon and money pit, and now has a BMW 535 and I swear something is ALWAYS wrong with that thing. The shop has it more than he does.

[@jandro2rich]

How’s it going now

[@r3wturb0x51]

actually, #1 problem with these engines is the lack of baffles on the valve cover gaskets, which allows oil passage in the vaccuum lines. buy after market valve cover gaskets with baffles and the oil consumption is greatly reduced. my theory is that this contributes to the timing chain issue greatly.

[@jamesh2711]

Just had my valve cover gaskets replaced with the OEM ones , wish I had read this earlier :(

[@elijahlopez9717]

I have a 2009 Cadillac CTS and I've had a couple of crankshaft position sensor check engine light codes and got them fixed. The most expensive job was done on the timing chain because when I went to the dealership and they took apart the covers and stuff like that, they experienced the timing chain actually falling apart as they were taking the covers off. Sounded like a knocking noise soon to be that the actuators weren't getting the right amount of oil for variable timing. Hefty jobs. Now that I know about what Cadillacs are about now, I can prevent these things from happening.

[@michaelbaka4777]

I have an '08 CTS Performance with 88k on her. Fan-TAS-tic automobile!!! Really quick and fast, NO major problems EVER. Owned her for over 5 years now. Have had none of these problems except the passenger front door handle has quit on me. I thought it was a programing issue; took her to the Stealership for a reprogramming to fix said issue. [Never said to just repop her, just that the outside handle stopped working!] They had the car for 2 days. When I come to pick her up, service manager acts like it's the task of the century to repop the system, had to do it twice, etc. $600+ later [!!!!!!] , now working, brought her home and didn't drive her for a couple days. Lo and behold, I can't open the door for my love!! Broke again!!! No recourse on an electrical repair!!! So, she's still broke! Thank you SOOO much for showing how to test it and what the switch looks like; I may tackle it myself when the weather gets warmer, as it's pretty cold out right now! Thanks again! SUBBED.

I still have the 2008 CTS4 I purchased brand new in 2007, it was "Car of the Year" for 2008. Problems I'm now having are primarily electronical, a/c controls quit working, rear windows roll down on their own, car occasionally goes into "limp mode" where it will only go about 30 mph, and driver door will not automatically unlock from outside (must use key). Car only has 83K miles so hate to let go of it but it is becoming a money pit.

Door handles and speed censors did not fail on the first gen. The first gen was just a camaro v6 on an extended frame. With almost 280 hp and 260 plus torque it drove like a formula firebird. But there is a problem. The trans wants to make the car smooth and in doing so runs in toigh positions. If you have this car just drive slow because its been tuned to be a comfy cruiser with occasional get up if needed. If you want to race around get a v8 camaro.

[@donguhl2499]

I have a 2009 CTS , now at 100k miles and 11 years old. Had to replace both rear wheel bearing assemblies. Both rear door latches stopped unlocking and need to be replaced. The cam chain was replaced under warranty due to an error code regarding cam position. Just recently replaced the coils, as 2 failed. Now I need to clean the sunroof drains and the external trunk release button does not work. I still love my car! Very cool video and pretty accurate compared to my car.

It was a nightmare replacing my stretched timing chains. Paid a guy 1800 to do the work and he ended up making it worse then paid I think around 4000 or 5000 at the dealership to have it all redone, way too much money but I'm invested at this point and it's running great again

[@MrOddfello]

I have a 2010 CTS and this year I have had to replace 3 wheel bearings due to the reluctor rings having rusted through, and also the timing chain had to be replaced. I have heard that many timing chains have to be replaced as the vehicle nears 100K though (I'm at 80k). I do love the car though and plan on driving it at least a couple more years. Nice vid, Subbing.

[@TheSuburban15]

Timing chains and belts typically have tensioners, which prevent engine damage when the inevitable stretch and wear happens though. You have to wonder if GM planned these to fail intentionally.

[@joshuapriddy2383]

[@aperson9495]

Only issues here I've had so far on my 2010 CTS is wheel speed issues. First was RR erratic signal, and when I got the hub out, it seems that hub just had magnets 'glued' to the back of the hub, and one set had fallen off, rendering it worthless. The hub itself was completely fine. The second was the LR a few months later, and that one seemed to have a 'magnet ring' like you might expect, and the ring had fallen apart. Replacing wheel bearings on these cars is NO FUN. I'd say a hydraulic press is REQUIRED, but there isn't a good way to get the knuckle in a press to press the bearing out (at least not that I've found with the rears - maybe some sort of jig could be made or exists to make it possible to press them out in a press). Note to Cadillac and wheel bearing manufacturers: How about make either the bearing or the knuckle with some sort of knurled surface to reduce the contact surface area, making it theoretically less likely to result in the bearing and knuckle becoming one or two steps short of permanently welded together?

[@jayholman502]

Man, my RR stays malfunctioning. I've replaced the hub, the abs sensor and tmps when I got new tires. It will be fine for a couple weeks then go out and not read anything for the Right Rear only....smh. Wtf!

I can't complain too much. I bought it for $1,000 as it sits with a clean title. While I'm at it with the timing, it's also going to get a variety of fresh seals in the top and front of the motor, every fluid under the hood flushed and replaced, new plugs, coil packs, air filter, pcv, O2 sensors, transmission / transfer case / differential service, new serpentine belt and tensioner, and finally, see if I can figure out where the water is getting into it from. It does have the panoramic roof. After all that, I'm hoping it will wind up being a good car for quite a while.

The first thing that went out on my Cadillac cts 07 was the ignition coils. Then some nut/bolt for the gear shift that needed replacing, then catalytic converter, then timing chain, and I just replaced one of the rear wheel bearings. It cost me $1500 to replace the timing chain (HAD to fix it to pass smog check) I replaced the alternator and camshaft sensors myself, and I do my own oil changes with synthetic oil. A new annoying problem is when I have my headlights on and I turn either blinker on, my brights come on and often times I can't get them to turn off. Complete money pit with my car. I should get rid of it but I've put so much money into fixing it that it's kinda hard to.

Timing chains and cam position sensors should not count as CTS specific because more than half of GM's fleet uses a version of this motor making them service items for all of the vehicles it is in use in. The test details are very good, especially isolating the door handle switch vs. the actuator. My one criticism however, is how you let the door panel hang off what appears to be the harness that goes to the power mirror. My passenger side actuator was replaced and I suspect willful carelessness like that is why the power mirror on that door no longer works and is currently throwing an open circuit code, (possibly partially disconnected plug, or damaged wire) perhaps because of a similar action by the installer, or it was unplugged and forgotten. Haven't looked into it yet.

I have a question I get p0455 I've change the evap n also the gas cap but I still get a check engine light on and ever once and a while I get check gas cap n also I check the valve that is under the rear my question is that harness that connects to the charcoal canister is there suppose to be power going through it ?

[@pamsco49]

Great video! I was wondering if you could advise on diagnostic codes P0011, P0301, P0300, P0303, P0305 on Cadillac CTS 2007 3.6

[@1AAuto]

+pamsco49 We wouldn't be able to diagnose an issues like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1AAuto.com

[@gordonliddy9418]

Only has a wheel bearing ring go bad so far. Think im due for some suspension work soon though.

[@danielprice5650]

Getting ready to do new camshaft solenoids. Does it need a relearn done after? I’m thinking no. But just want to check.

[@marionapoli6540]

bought a 2011 cts base 3.0 last year with 102,000 miles on it, currently have 126,000 on her. now im starting to get some issues, nothing crazy. cam sensors rear wheel bearing, heat shield is rattling. replaced battery, alternator and front right axle few months ago. other then that its been an extremely reliable daily. mine definitely doesnt have timing chains though. has timing belt

[@johnhernandez6149]

Hey some I’m around 136k miles and I think it’s my heat shield or something rattling bc mine rattles at like 1500 rpm’s the most and sometimes at idle. Also had you know the axel was bad bc I feel like mine might be as well?

[@jamesbrown3965]

Great video was looking at a cts with 116000 miles probably will need a timing belt looks like their 15 hundred to replace so i think i'm gonna pass on that purchase you earned a like and a subscription ..very impressive and informative video !!!

[@1AAuto]

+James Brown Thanks for the great feedback. Much appreciated!

[@YourRealDaddy]

I have 10 codes and 6 of them mention "wheel speed sensor" lol. Also, the turn signal lever seems to be a common problem because many folks complain about their brights kicking on for no reason. Me being one of those folks.

[@brittainyhowk8206]

Door handles yes! Trunk leaks too. Working on getting misfires taken care of, replaced spark plugs. coil replacement or control module maybe...

[@XxXGREENMONSTERZXxX]

Have you figured out how to fix trunk leaks ?

[@santosmercado6422]

I have a 2011 cadillac srx and when I have to stop suddenly or my wheels spin on ice my brake pedal looses pressure and goes to floor.I turn it off then on and it get firm again.Any ideas.

[@WaVeYBabyV]

I have a 2012 CTS and I hate the fact that anyone walking by can just open up the fuel door with a press and put whatever they want in there. Don't leave this car on the street if you live in the hood and/or have enemies.

[@Ghoststalker777]

Buy a locking gas cap. I've put one on 3 of my cars and never had a problem.

[@rusco321]

More of these videos please.

[@CarmacaddyV]

I have a 2016 Ats v and a 2009 cts 3.6 the 3.6 is currently having crank shaft position sensor issues I just bought the part going to change it this weekend

[@zracer1099]

I have a 2008 cts with 75k. It’s showing p0366 and p0306. For the po366 would that be the last part in this video? Also solutions for these codes I’d appreciate!

[@mindSoulEnso]

Hello Im a owner of a 2010 cts wagon and im freakimg out. Just recently "today actually" my powersteering just failed. I maded the obvious inspection starting with the reservoir no issue there. I also notice smoke coming out on the left side of my engine that I never seen before question does that have anything to do wuth the power steering pump failing?. Any help would be great thank.

Great video but......let's remember this is the regular CTS not the V I've owned all 3 generations. With that being said I agree the door handles suck. Mine went out in my 2010. The shocks I would say is 1 of the major issues and also wheel alignment issues. Each generation has it's own set of issues.

[@1AAuto]

+Mr. Wallace Thanks for checking us out. 1AAuto.com

[@johnhernandez6149]

How did you know the shocks and alignment was bad?

[@khadejhiaambrosejones-mosl1360]

Yulp...🤑I have one and my engine light is on the code came back to being in need of timing chain and I also have the abs light on thanks you were very helpful 💯🖤

The chains don’t actually stretch. They wear elongate due to dirty oil. Y’all have been fooled by the recommended synthetic oil change interval.

[@jonthancaballero3959]

Hi. I’m actually not having any sound come out the radio or any sound at all when I put the key in. I say about a week ago it started to hesitate. Would you haven anything in mind that could be wrong with it?

[@Ember1315]

How big of a job is it to fix a dsc light in the cts?

[@johnnygregorio7200]

hey buddy, realistically how often should i service the rear differential fluid on these cars?

[@claussorensen4269]

Great job with the explanation.

[@urnomatch4me96]

I have 2006 sts4 i just did the purge solenoid that's good. My door have the problem n motor still going good. 160,000 but it got me scared about the timing. What mileage do most people have with the timing chain going bad?

[@steveo201]

Dave for the Save mine started rattling bad at 235000 miles I’m At 245000 just unbolted my exhaust system it’s not far from being scrap metal 05 srx model

[@delallum5654]

Hey guys your are really CAR MAESTROS! 😎👍

[@mardybum4540]

Awesome video thanks v much :)

[@richardparker471]

Had mine for 130k miles and only had to replace water pump.....and engine at 120k. They tend to have an oil consumption problem so make sure your oil is changed on time. I tried to do the 20k oil and filter bit it ran out at like 14k miles without a change. I now change it on time and use royal purple lol the oil consumption is fixed on my engine from LKQ.

[@rockford8915]

Could you please make a video discussing the chronic leaking problem with the sunroof? Both my 2008 and 2009, with the sunroof option, leak water into the interior foot well areas when it rains. Most times the passenger rear foot well area gets wet, but at times, any/all of the four foot well areas will have wet carpeting.

[@ceasarblack20]

Have the drain line's cleaned out.

[@johnnyg9507]

@Greg Hertko The rubber grommets that the plastic hoses for the drains connect in to go through the body, in the front kick panels and in the trunk in the side panels need drilled out. They come out fairly easy. The center of the grommets have a couple of small slits for drainage, and stop up easy. Just cut out the whole inside area with a drill bit. Flooded my cts also, i watched a utube vid to figure it out. Is actually easy once you see how its done, time consuming, is worth it tho. I did it last year and have had no problems since. Trunk leaks from crappy seal on 3rd brake light I suppose,,lol.

[@fatcat4155]

I seen two 2011 cadillac cts 3.6 on Craigslist today for 2000 dollars a piece. Both needed timing chains. Still a good deal even after you put 2000 thousand dollars into them.

[@themechanic6117]

Thats assuming the timing chain is the ONLY problem which I can bet isnt the case.

[@acham3258]

Im about to buy a 2012 with only 47xxx miles. The dealership had to put on pause cuz the power steering had issues....now im hesitant but i love the car

[@davidrichardson4175]

My 2009 just started stalling while driving and acceleration I recently had a spare on for awile would that affect the timing

[@loeveyou]

hello i know this video is for 4 yr ego but i fund you now and im so happy at the first i want thank you for your video to can help me. anyway I have a 08 CTS and my car engine light is on and problem code is I think P0008 or something like this so you say I need change engine oil I wanna ask you what is the best oil for my car?

[@icecreampusha]

The CTS-V I’m looking to buy has the door issue. I can hear the electronic motor when I pull the handle. However, the door won’t open. What could that be?

[@t.johnmcmanus204]

Very good. I am thinking about buying a 2012. It has 80,000 0n it Have not yet. Just thinking about it. My question is this. If the chance the oil say on a regular basis and say half on the dip stick. I should avoid some of these problems is that correct or not.

[@kevinsantiago260]

Beautifully explained bro!!!

[@1AAuto]

+Kevin Morales Thanks for watching and the feedback!

[@DjShouOut112]

How do you bleed the cooling system for air in the same car?

[@corionh4775]

The timing chains themselves aren't the problem on these GM 3.6L engines, they stretch/break because these engines burn oil (usually PCV system flaw) and most owners don't check their oil level or keep them topped off.

[@1AAuto]

+Corion H Thanks for checking us out!

[@antoniodiaz1887]

Would you recommend a used CTS wagon? or would that be a pass for you?

[@darrellcole6070]

I have a used CTSwagon I love it even though someone T-Bone me sometimes I have a headlight issues and I went through a Delta Sonic car wash in a trip part of my tail light offyou probably will have tail light issues as far as them poking out but other than that I still love the car I've had it fixed since the accident and it's fine

[@kylemoore9626]

Did you end up getting one? I’m looking at one too
