The front right side headlight had moisture buildup inside the fixture .plus the fixture had discolored and faded and was not clear. Apparently the sealant around the headlight fixture did not make a permanent tight seal therefore water entered inside. As a result the daytime light went off and on and the signal light did the same. The safety issue was while in motion on a city street turning the driver facing me did not know I was signaling and the driver behind me saw fast signal lights flashing from my chevy cobalt. I had my complete headlight light assembly replaced by a body shop and this corrected the whole problem. It cost me $173.52

My car has had regularly scheduled maintenance since we purchase it in feb 2011. Today, as my husband was driving it, we believe the engine just blew up. The car started shaking, the check engine light came on, then there was a loud noise and the car shut down. It had to be towed back to our house. We have no idea why this happened or what to do. We currently still owe money on the car. It is still financed. This vehicle was constantly at chevrolet because it had problems. Many of them they refused to fix even though we bought the extended warranty. I took it and complained about the dash acting strange, the gauges would jump and the digital would go to all dashes, they replaced something once and it still did it. I complained several more times and all they would say was they could not get the issue to replicate. There have been oil leaks that were replaced under warranty, it wears out shocks like crazy, both front hubs have had to be replaced, there has been water in the head lights, 1 was replaced by the warranty but then the other my dealership refused to replace and I had to pay to have it repaired. Water leaks into the passenger side front floor board from under the dash, the dealership said it was not covered by the warranty, water leaks in the driver side floor board from under dash durring and after heavy rains, dealership stated they could not replicate the issue, not to mention the recalls. We have done all the reg. Scheduled oil changes and service. It has gotten new spark plugs and new coil packs. Now the engine is blown up with only 135000 miles on it.

Have been told various times I need new struts and shocks. I think this is ridiculous seeing as though I have do not have many miles on my car and the year of my car. Dealerships have told me that it does not make sense that a car a 2006 and with low miles on it should need shocks and struts right now. I have had nothing but problems with this car since I paid it off. Wheel baring, shocks struts, problems getting key out of ignition, headlights and tail lights leaking water into it, slve cylinder and master cylinder, fuel pump. I will never buy a chevy again!

A/c not draining properly .water coming inside of car on passenger side carpet.

Filed Jun 24, 2010 · Electrical, Fuel system · TX

I have owned my 2006 chevy cobalt since june 2006 and have had numerous problems out of this car. I have had to pay out of pocket for every repair because they seem to all happen before a recall is issued and the dealerships will not refund money on the repairs. 1) A/C leaks water in passenger side floor board. I have had it in the shop 3 times and it is still leaking. No one can figure out why the water is leaking into the car. 2) gas tank had to be replaced due to fuel lines cracking. 3) power steering went out while my husband was driving on the interstate and was about 130 miles from home. 4) the car would die if the RPM's got too low, this was caused by a carbon build up on the idler. 5) there is no way to check the transmission fluid and it is starting to slip and take forever to upshift. 6) the key gets stuck in the ignition and will not come out. 7) the drivers side door gets stuck and will not open. 8) the door latch sometimes messes up and the door does not close. 9) the stereo display and buttons no longer work. I can not use the cd player for fear of losing the cd for ever since the eject button doesn't work. I can not see the clock or what station the radio is on. The car lost its value so fast that even after 4 yrs of having it I still can not trade it in due to the amt. I still owe on it. So I am stuck driving this piece of crap until it is paid for. I have already invested several thousands of dollars into this car for these problems. I believe that the car is a lemon and I should be reimbursed for the car and all of the out of pocket repairs I have had to make.

Defective lining in car. Car has been sent for service over nine times in four years due to water leaking in vehicle. Everytime it rains both back seat floor boards are soaked. They have replaced the lining and replaced the carpet once and vehicle continues to leak. I have had the vehicle since 2006.

I have had my 2007 cobalt back to the dealer so many times. One of which was for strut mounts, control arm bushings, intermediate steering shaft, sway bar links, alot water coming in through the center brake light. Those were replaced and very bad at 48k miles they told me it had reached the dangerous level and that they're glad I brought it back before somebody got hurt. Also the AC smelled terrible at 12k miles, it was in the dealer 7 times for that terrible smell. The last of which took them a week to put in an evaporator which only cured the issue for 3 weeks. It still smells awful when the A/C is running. As far as the car's suspension, since december it has been very hard to manage the car on the road. Its all over the place, I've almost side swiped a few semi's and I cross into other lanes almost every day I drive it. Its very hard to handle. Its is just about impossible to make the car go straight, its always drifting all over the road now.

I have a 2006 chevy cobalt 2dr coupe. First, about a year ago my power locks stopped working and they would randomly go up and down while I was driving. I got that fixed and then on 12/28/2008 I was driving from shreveport, la to chattanooga, tn. It was fine for most of the trip but as I was getting off the exit in chattanooga, my power steering went out. At first it would do it randomly but after about a month of it happening now it happens every time I drive the car. It works when I crank the car up but after about 1-2 miles, the power steering goes out. I took it to the dealership and was told that it needed a steering column and it would cost $1200.00 which I could not afford. Then last week on 08/02/2009, a lot of things stopped working. The odometer, cruise control, temp. Gauge, and speedometer. And the car would not change gears. Since it stayed in a low gear I could only drive about 30 MPH to take it to the shop. It turned out that it needed a transmission control module and it cost $362. After that everything started working again except the power steering. I know this is a common issue as there were over 500 complaints about the issue on the one website that I looked at and that's only one website (www.topix.com/forum/autos/chevrolet-cobalt). I feel that this is a very dangerous problem and something should be done about it! Also, the air conditioner has leaked water onto my passenger side floor since I have owned the car and I have also read that this is a common issue.
