Sadly, that’s true for the quality (lack there of) of parts Chevy put in this car. I’ve replaced most things in this car at least twice some parts more. Even the ECU/computer fried literally… The original battery didn’t last a week before it split open and leaked. Mine (2014) has 285k. The Scion Xa I drove for 9 years prior to this car had 326K and I barely had to replace any parts.

[@melissa.simplystatedcoaching]

Thank you for saying Choosing this type of car was a smart decision because I did the same thing and everybody gave me hell about it. Lol

[@JimmyMakingitwork]

Yeah, everyone has to have some kind of budget and cars like these are not only cheaper to buy, but also to maintain and also good on gas. There is no perfect car for everybody, but if taken care of these will give a good life span and value per dollar.

Hey Jimmy, first time watcher here. My girlfriend has a 2012 Chevy sonic. Car has been misfiring lately, turbo has starting taking longer to kick in since it started tweaking out. Around the 2700-3000k RPM range she has lose of power. Will be doing spark plugs today and oil change. Car has also been making a loud whining sound which has been getting louder by the day. Thanks and the help would be appreciated! Great video by the way 🤘🏽

[@JimmyMakingitwork]

I would check the air tubes from the turbo to the throttle for leaks, also look for codes. A little spritz of brake clean around the clamps might help change engine speed to show leaks, just don't spray it near the exhaust while it's hot. If it has some miles, pulling codes and a compression test would likely be the first things I'd do.

This car is a Daewoo, modified by GM engineers when GM took over the Daewoo factory. I think the 1.8L engine was designed by some European countries. At 100,000 miles I would change out the Ignition coil anyways with an AC Delco or GM genuine and same with the valve cover gasket, I use FelPro and it works great.

[@Floridagal_657]

I just had to see a mechanic about my 2012 Chevy Sonic lt hatchback with 33k miles. From the beginning when I got it, in April 2022, it was idling rough and the headlights were dimming with each jerk of the engine. There were no codes here either. This is the third car I've traded to in two years time and the manager that sold me the car was avoiding my phone calls, texts and emails and not fixing any issues I had with the car. He had promised he would fix any problems with the car, give me a power train warranty and lifetime oil changes so I was holding him to that. After contacting the company VP, he had the customer care department reach out to me. Kelly got me in to see someone in the service department. We went for a ride, sat in idle for a few minutes and it jerked... or misfired is what the mechanic called it. That's also what brought me to check out your video. I was having the same problem as your caption on this video. The mechanic says it was possibly due to bad gas. An elderly lady owned this car before me and it had been sitting up, unused for awhile. He reset something in it to relearn the gas and put a gas treatment in it. It's day three and it seems to be running ok thus far. No jerks/misfires as of yet. I'm not sure what will happen once this gas treatment is used up! Hopefully it was bad gas or some water in the tank and everything will be okay from here on out. It's such a piece of mind while idling at a red-light or waiting to merge into traffic. At least for now, I'm not worried about it dying on me! So where are you located at? I really wish you were nearby... I sure would feel confident having you as my mechanic! Just saying...

[@JimmyMakingitwork]

Wow, seems like the gas will have you fixed up! I am in Central Florida about 15 minutes from the rat…errr, mouse. :)

very informative Thank you I love reading the comments I learned such a lot and I’m having similar issues as well

[@JimmyMakingitwork]

Glad it was helpful!

[@pjstartv6798]

The PCV built into the valve cover on the 1.8 and the 1.4 Turbo engines in these cars is a known issue. GM upgraded the valve cover at some point so the replacements are better but still not great. My 2013 has just over 90k miles on it and recently started stumbling/shuttering at idle, not noticeable at higher RPMs and no check engine codes but noticeable loss of power as well. I'm planning to change the plugs this weekend as they have at least 50k miles on them and likely need it regardless. It might need a valve cover but they're running in the $50-$60 range so it's going to have to wait plus when the PCV fails it will almost always throw a code for a vacuum leak.

[@JimmyMakingitwork]

It also would be a good idea to add some fuel treatment or perform an induction service to reduce carbon on the valves. This often helps idle quality.

Very similar problems with my 2014 1.8 l Sonic. Install the new coil pack ran fine until the next morning same problem brought it back checked it out it was the electrical connector to the new coil pack not the coil pack part of the connector the wire harness part so I used a little dielectric grease on the coil pack fittings and put it back together it works fine now

2016 Chevy Sonic LT Hatchback 36,000 RPM shoots up to 6 1/2 if I try to go over 60, car feels like it's dragging, little engine shaking. No codes, no one has figured it out yet. Good starting point.

[@JimmyMakingitwork]

That sounds like something along the lines of major battery cable connections, a module that’s corrupted or an alternator putting out AC intermittently? It will be time consuming to pin that down for sure!

[@jbuck1975]

Daughters car is running rough and check engine light. Pvc was sucking and oil leaking. Replaced valve cover. Changed spark plugs. One of the springs had corrosion. What should i look for ? While car is running almost sounds like i can hear leak but heard to tell because engine running.

[@JimmyMakingitwork]

When I suspect a vacuum leak I sometimes use a stethoscope to pin point it, or spray water in the area and see if it changes how the engine runs. This helps show where to look closer.

I have a 2014 Chevy sonic and ive replaced the crankshaft position sensor three times now after the guage stopped working and engine light came on. Just changed out crankshaft position sensor 5 days ago and its already given out again. What do you think could be causing that?

[@JimmyMakingitwork]

Could also be a connector, or computer problem. Sometimes a wire can get rubbed thru on a bracket or bolt it passes. Have to look the harness over.

[@nirvanarocks15]

Why the whole valve cover? I've been dealing with the same car, same miles, misfire in 2. Oil was getting into the spark plug tubes, replaced spark plugs, then valve cover gasket and cleaned quite a bit of oil out of the boots in the coil, and spark plug tubes. Now it's got random misfire. May just be the cover and coil, like yours. Girlfriend's kid's car.

[@JimmyMakingitwork]

Yeah, they have a baffle and diaphragm in the valve cover for PCV. When it ruptures it cause noises, weird idle, lean codes like P0171 and P0300 random misfire codes. You can usually put your finger over the vent hole in the cap on the valve cover with it idling and feel a vacuum that you should not feel. Hope this helps.

[@nirvanarocks15]

​@JimmyMakingitwork Thanks for the reply! Yeah, I did see what you're talking about when I was in there. It felt just like yours after I did the gasket, tons of vacuum in the crank case as well.

[@shawnpierson7672]

thank you for the video. A friend's car was smoking bad from tailpipe and engine running rough. local mechanic told them they'd need a $7000 engine replacement. I hauled it to my house and found oil in the pcv hose at the valve cover. cleaned oil from hose internal, smoking stopped. As you showed, I pulled dip stick and a lot a of air was sucking in the tube. Removed the oil cap and engine sputtered and died. I pulled valve cover to see the pcv. used my mouth and could blow and suck through the hose connection stub. I assume there some type of pcv valve in the circular moulded area in the valve cover. have you broken or cut open the diaphragm area to see what's in there?

[@JimmyMakingitwork]

Yeah, it’s a rubber diaphragm and when the tear, it will burn oil and leak from seals, all kinds of odd idle problems. New valve cover!!! Some vehicles you can replace the PCV baffle assembly, some it’s one part.

[@mlieser1230]

Happy Thanksgiving! I have a question. I notice that this car has a direct ignition cassette. Back in the 90s SAAB ran a direct ignition on the 9000 series. They were pretty sensitive as to what spark plugs were used. If you ran anything other than the specific NGK plugs misfires would occur. You mentioned that you would have preferred to install AC Delco plugs over the Champions. Have you run into any misfire situations caused by the wrong spark plugs? Around the late 80s early 90s Bosch Platinums were all the rage. Many a 900 Turbo would come in popping and skipping. These cars ran a conventional ignition (standard coil, distributor, and wires). Sure enough we would pull the plugs and find Bosch Platinums all fouled up. A fresh set of NGK platinums and the car ran like new.

[@JimmyMakingitwork]

Yes, very possible. I’ve had a few vehicles that did not like plugs with slightly different resistance and it would cause all kinds of odd problems. One Chrysler Sebring we had was setting 02 codes and would misfire cold because of the incorrect spark plugs. Have to be on our toes!!!

[@switchfoot8702]

Great video and instructional… my wife’s car, 2018 Sonic 1.8 has a rough idle, stalling and dying, had a thermostat go bad, replaced it, then showed vacuum leak, changed purge solenoid valve, fixed the code, now it has a rough idle. Any recommendations for the rough idle, no current code, suggestions? Thanks… gave a Sub and a Like!

[@JimmyMakingitwork]

If fuel trims are correcting at idle but not off idle it has a vacuum leak. I often cover the valve cover baffle with my hand to see if the diagram went out. Which means valve cover replacement. Hope this helps! Thank you!

The valve cover, it contains the PCV assembly.

[@SoCalKing88]

Have a question hope you can point me in the right direction. So when driving at freeway speeds and slowing down to about 40mph and then accelerating back up to speed it struggles and starts to make a clicking sound and sputtering like it wants to die and some smoke out the pipe . No codes . Runs fine before and after it happens. Have replaced valve cover ,purge ,coil pack , new cat. Replaced the thermostat housing twice. 120k any idea I appreciate if you take the time to read and reply

[@JimmyMakingitwork]

It sounds like an ignition misfire, but you did coils already? Maybe spark plugs. Might also want to check compression in the engine. Might be getting tired?

[@kimkennedy1105]

having this same issue ive replace the compressor 3x in 5 years. i just replaced the compressor a month ago it went out again! now I'm learning I have a misfire. it stalls every other time when i hit the brakes.

[@JimmyMakingitwork]

It sounds like a similar problem. The compressor is possibly something to do with either oil in the system not being at the right level, or a condenser restriction making it work too hard. Also a slight possibility of parts that aren’t as good as they used to be. :( Hope you get it sorted!

[@XsuperXrcrazyX]

My 2013 chevy sonic has been stalling at idle and idling rough, BUT it has also stalled while pulling into a parking lot right when I gave it gas and got up to 12 mph. The coil pack and plugs are less than 30k miles and I dont know what to do

[@TheThirdWheel618]

how much was too much vacuum on the dipstick looked like around 15psi I know the PCV valves fail often on the valve cover . if you pull the dipstick out while running and acts all rough then it's a good.sign it's leaking hissing too right ,?

[@JimmyMakingitwork]

Yeah, should be about 1-2 in vacuum and opening the cap or dipstick will vent the crankcase and change the way it runs if the valve cover is bad. Thanks for watching.

[@danielgeng2306]

Ok, I gotta ask, why would the valve cover leaking cause excessive vacuum in the crankcase?

[@JimmyMakingitwork]

The design of this crankcase system has a pcv breather or baffle built into the valve cover. So when the diaphragm ruptures in it the symptom is very similar to a vacuum leak, but without effecting the fuel trims very much, since it's pulling crankcase fumes rather than pure air. It can cause crankshaft seal noises, stalling, all kinds of odd symptoms also. Thanks for watching Daniel!

Hey Jimmy, I have a 2013 Chevy Sonic and just like this one I had to replace the ignition coil pack. I find that occasionally when I stop at a red light the car will do a very very small jerk that's hardly noticable and does not seem to affect the rpms. I've been having this problem both before and after replacing the coil. Do you have any idea whatsoever of what could be causing it or if it's even a problem? Thank you!

[@JimmyMakingitwork]

Hmmm, if you don't have a check engine light it may be unrelated to the electronics or be normal. Possibly suspension? If it happens just as you stop. If it happens while your stopped, it could be idle hunting that can happen when AC compressor cycles and alternator load changes, things like that.

[@dave_bed]

[@RandomNAME-cs6kw]

Do you mean when slowing down cause in that case it would most likely be shocks or your motor mounts. If it's when you're stopped, check your spark plugs and see if there is oil on them, then you might have a leaking valve cover which is common.

Hi, I have a 2013 Chevy sonic that jolts forward when I’m in idle and has been making a sporadic high pitch whistling sound after driving it around. I just had a tune up and changed the oil. There’s a code 52 showing up but I’m not sure if these issues are related to the timing belt from my research. I appreciate any help!

[@JimmyMakingitwork]

Christina, I would pop the oil fill cap off while the whistle sound is happening and see if the noise changes. The code 52 is odd, is it a P0052? The engine in your car should have a timing chain and not a belt. If there is a problem with the chain the codes would be timing related like P0300 and similar.

Also when car is on I pull dipstick out and seems like air comes out but I’ve changed everything I don’t get it. Next step I’m doing is adding a new intake manifold

[@JimmyMakingitwork]

Hello Ricky! The Sonics can sometimes have the baffle go out for PCV in The valve cover. There are some, depending on year, that can have a check valve go out in the manifold. The valve cover is “usually” the culprit in my experience, but either is certainly possible. The manifold issue is “usually” a clogged orifice that can be cleaned and a rubber valve that can make replacement necessary. Good luck! If I can help, let me know!

[@JimmyMakingitwork]

With no codes I use a scan tool to check for engine RPM in data while cranking. See if it sees the engine turning. After that I use a spark checker to see if the plugs are getting fire…if they are I try an alternate fuel source, like brake clean or ether…if no results after that I check compression.

[@JimmyMakingitwork]

This is usually a Cam/Crank Sensor or circuit problem involving it. Hard to say for sure without seeing the issue myself. I would get the problem to occur with a good scan tool on the car and see what happens during the issue, without turning off the key. Then test from there based on that data.

[@JimmyMakingitwork]

The idle rpm can vary with conditions and engine temperature, but 550-800 is the common hot idle speed usually. In park and neutral the computer will limit engine speed to prevent damage, since an engine is designed to only rev at higher speed will working to move the vehicle. Hope this helps!

For one, look at that radiator fluid! That’s not Dexcool orange!

[@JimmyMakingitwork]

There are a few extended life coolants on the market now. The one we use mostly is gold and takes on the color of what it's added to.

@@JimmyMakingitwork why those engines got so hot?

[@ralphbeauchamp3517]

I got a Sonic with a check engine light. No one can figure it out. Code is the variable valve timing solenoid.

[@JimmyMakingitwork]

The solenoids go bad often, but I also check for metal debris in their screens. The screens sometimes come apart and jam the solenoids open.

[@ralphbeauchamp3517]

@@JimmyMakingitwork They can't figure out why it keeps throwing that code. After they replace them. Light comes right back.

Hi! What silicone did you use?

[@JimmyMakingitwork]

I use Permatex Ultra gray.

[@tevaunsmitherman3032]

Hey. Where did you exactly order the valve cover from?

[@JimmyMakingitwork]

I believe we got this valve cover from the dealers parts department. They should also be available thru Napa.

Spark. Plugs could. Be bad mine went bad at 56k miles on my 2014

Yes, they can go bad also!

its not an aveo, whole different car. those who own those cars like them.

[@JimmyMakingitwork]

Thanks for watching.

[@bretmuldner]

You never sad why it needed a valve cover, what vwas wrong with it?

[@JimmyMakingitwork]

The valve cover has a breather built in that goes bad and causes whistling noises, or oil burning and rough idle, lean codes sometimes.

[@altpath]

Looks like that car has the wrong antifreeze. Not related to this issue, but that should not be green.

[@JimmyMakingitwork]

Which car was it, I can't remember one with the wrong anti-freeze/coolant recently. There are about 12 different ones now, so we have charts and manufacturer information to determine what goes where. The imports now use either Red, Blue, Green, Pink mostly. But there is an import green that is more transparent than the classic green coolant. :)

[@altpath]

@@JimmyMakingitwork oh that one uses dex cool, it's a red/orange. Just thought it was funny with it.

[@AFatherToTheFatherless]

That orange coolant is absolute GARBAGE it corrodes everything. Put the green stuff in there trust me!

[@pjstartv6798]

@@altpath They're likely using the Universal antifreeze that can mix with any color of antifreeze. That's what I use in my Chevy Sonic. It's not green but due to the yellowish color of the fill tank it kind of looks green.

[@emilyk0209]

I have a 2015 chevy sonic LTZ with 60k miles. It stalled while driving down the road the other day and had to be towed. The mechanic said it wouldn't start for them but then "floored it" and it started. No error codes at all. I've read about stalling problems with sonics but with no error code...what should I do? :(

[@JimmyMakingitwork]

Problems like this are usually things like engine rpm dropping out from things like a bad sensor or sensor wiring, or battery cable connections, or even an ignition switch sometimes. It will take time and patience for a professional to sort out with no codes.

[@mikezerucha5452]

Same with me smh

Update?

They have a few troubles, but really not bad cars once you sort them out.

[@reneg1366]

Have a 2015 Sonic, starts perfectly fine, had it running for a long time, then customer drove and later it started running rough and stalling at the light! Starts up quickly then starts to run rough, NO codes! Disconnected purgle valve and blocked off, still runs rough, no vacuum at all at dipstick, threw a 506 code - low rpm. Not sure what to check for? When cool starts fine, no issues, problem when warms up, any help would be much appreciated 🤔

[@JimmyMakingitwork]

Something like this I'd be looking to see if crank data drops off, although it would usually set a code. Could also be loosing ignition voltage and behaving like the key is turned off?

[@reneg1366]

So there shouldn't be any vacuum at all at the dipstick?!...

[@JimmyMakingitwork]

There is a measurement for it. Usually under 1”. Depending on the vehicle specifications. So a slight vacuum.
