Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CarComplaints.com Notes: The 2007 Cobalt inherited most of the problems from the 2005 and 2006 model years, but toned them down (a bit). Sure, the power steering still fails and the car has a chance of going up in flames due to a cracked fuel tank, but it’s not as prevalent as the older models. At least not yet.

In 2012, the Cobalt was recalled for gas tank fires but only for owners in certain states.

Then in 2014, the 2007 Cobalt was part of a massive GM recall due to a defective ignition switch that could cause the airbags to not deploy during an accident. The problem led to 13 deaths, government investigations and multiple class-action lawsuits.

Its been almost a month since my Cobalt went in to the dealer for it to get fixed. Hardly anything has been done for the car to be repaired. I have called to check and all they say its that is going to be ready soon. My daughter really needs the car for school and work transportation. Can something be done from the government so that the process can go by faster? it wasn't my fault that the car came out with alot of problems!

Cobalt 4-cyl

  • 70,000 miles
The first incident happen in 2012 and caused a crash. I was driving down the street and needed to stop at a red light and put my foot to the floor on the brakes and it did not stop me. I could not move the steering wheel either so I could not avoid hitting the lady in front of me. Luckily, I was not going very fast and everyone was okay. While exchanging insurance information, I noticed my keys were in the floor board of my vehicle. I didn't think anything of it, because when it came out of the shop it seemed just fine. Then, I was on the freeway on my way to work in 2013 and my knee bumped my key ring and they fell to the floor. I could not slow down or switch lanes. I got a speeding ticket. Then in November, 2013, the same thing happened as the first time which caused a wreck. I could not stop at a red light and rear ended a vehicle in front of me. I was barely moving whatsoever though, so I got lucky again. Recently, my check engine light came on and I took it to the autovbody shop in town and had to pay 800 dollars to get the timing chain replaced. I have had nothing but issues with that car and now I find out that many recalls have been issued on the vehicle and I have not been notified of a single one. Apparently GM was supposed to notify owners with their registration information. My registration just came up for renewal as of May 1st and I have not been notified or instructed what to do. It has gotten to the point now where I duct tape my key so that it will not come out while I am driving. I limit my driving to necessity travel because I am too afraid that something else, possibly worse, than what has already happened thus far.

I would be driving down the highway and the car's dials would not work then start bouncing around. Then the power steering message would read out, I would loose power steering. If I slowed down it would take more of an effort to get the car up to speed and the car would jump in to gears hard. It wouldn't shift smooth. None of the gauges would work, and if the A/C was on it wouldn't work. When it started back working, the engine lock light would stay on. And the car wouldn't shift in and out of gear with out jerking.

Cobalt 4-cyl

  • 93,000 miles
While accelerating moderately from a stop, the engine completely died while in first gear. I coasted to a stop on the side of the road and turned on the hazard lights to alert other motorists. Each time I tried to restart the engine, it sputtered and shook violently and then died. I kept trying for about five minutes and on one try the engine finally started and stayed running. The RPM gauge remained at zero even though I was able to accelerate and drive away from where I had initially pulled over. After about a minute, the RPM gauge started functioning normally. Please advise. Thank you.

This is my second E-mail to you about my timing chain breaking and destroying my engine which I had to replace at my expense ($5,100) because GM would not pay for the repairs. I am resending this because of the recent recall on Cobalts ignition switches that they knew about 10 years ago and did nothing. The timing chains on these models (Cobalts) have been breaking for years according to 3 mechanics I spoke to whom all said there should have been a recall years ago just like the ignition switches they ignored up to now. Please look into this defect because I have also herd from 5 other Cobalt owners who have gone through the same problem as me.( not a coincidence).

My timing chain broke causing damage to the engine block. I took it to my Chevy dealership to have it repaired but they wouldn't cover the cost. I towed it to my mechanic to replace the engine at a cost of $4,500. That is when I was told that the timing chain breaking is very common on this model car. Since this happened I have herd horror stories from other people who have gone through the same stress with GM. I also looked on line and found many other similar complaints. It cost me $250. To release my car to tow it to my own mechanic and they did absolutely no repairs. I called GM directly and they offered no help at all. The timing chain is definitely a defective part and GM knows it!!!

Cobalt 4-cyl

  • 22,000 miles
I constantly have problems with my 07 Cobalt, every time it rains, or it's wet out, the engine starts to shake violently, and gas starts spewing out of the tailpipe causing an immense amount of smoke to come out, but when it dries up, the problem stops, only to restart again when it rains. I've been to the dealership, and also private shops, and called G.M customer service, and no one has any clue as to why this keeps happening. This is fuel related, and im worried it could cause harm to me, and my family if not resolved. Somehow, water is getting into the fuel line making this happen and nobody knows how. It even happens when I run the a.C, when the moisture from the compressor drips down. It has been very costly to find no solution, any advice, or repairs that were done to fix this would be very appreciated and helpful.
