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.

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!!!

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.
