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. Notes: The 2006 Cobalt continued to carry the torch first lit by the 2005 model year. To be clear, that torch is burning bright with widespread power steering issues, electrical curiosities and a dangerous ignition switch defect which led to a massive recall by GM. This isn’t a great torch to carry.

The 2006 added it’s own special flare with gas leaks due to cracks in the “return portion of the modular reservoir assembly.” A recall of 2006 Cobalts was issued to fix the problem, but only to vehicles sold in or current registered in Arizona and Nevada, leaving other owners to pay for repairs themselves.

Between this car stalling while driving, giving owners fits with power steering failure and having it be a potential tinderbox because of gas leaks, we felt we had no other option than to award it our “Avoid Like the Plague” badge.

I drove my car the night before with no problems. Got into it the next morning and had no vents, air conditioning, or passenger side air bag. Took the car to the dealership and they replaced the fuses, said it was fine. Two days later the same thing happened again. Took the car back to the dealership and told them to find out why it keeps blowing fuses. It is there now. This is the third time it has happened. The first time was about 4 wks. After I bought the car. The dealership said they had to replace the whole wiring system.

Friday night at a gas station. Started the car. Engine shut off when placed in reverse. Would stay running in park, neutral, and drive. Drove the car home. Called langs Chevrolet in beavercreek, Ohio Saturday morning. Was going to drive car in to dealership. Car would not start intermittently. When the car did start, it would run for 2-10 seconds then "power steering" would come on. Air bag lights would come on. Various intermittent codes would come on. Most of the time the all gauges would go off and the car would not start. Lang had car towed to dealership Saturday.. feels like the steering column is loose. Also, front suspension/steering makes rattling noise over rough surfaces. Will make a rattling noise while sitting still and moving steering wheel back and forth will repost with the results. Others...please do not repost the same complaint! this bogs down our search capabilities. Thank you, paulj

Car was sitting in drive way for 30 mins and burst into flames, and the whole car is a total waste. The fire was so hot that the siding melted on the house. Nothing left of the inside of the car.. a eye witness said the fire started in the dash and when it started it was gone in less than 15 mins.

1) when purchasing this used vehicle from the dealer, we were informed the previous owner had broken his key in the ignition switch, hence the broken ignition lock mechanism. Lie 2) car began making a front end noise or so I thought, the next day as my daughter in law and my grandkids were driving home the power steering indicator light turned on, she applied her brakes to slow down and all the lights on the panel turned on and her steering locked. The truck behind us was forced off the road to avoid slamming in to us. After getting online to see if there was going to be an easy and inexpensive way to repair this problem I was appalled to read all the complaint regarding these same issues. I lost my oldest child to faulty seat belts on the 01 Ford Ranger edge. This is indeed a safety issued that needs to be resolved immediately before someone is seriously hurt or killed.

My 2006 Chevrolet Cobalt with 37,000 without warning did not start up properly the first thing in the morning. Car engine chugged along and would accelerate. The car didn't want to 'go'. related or not the car gas mileage decreased from an average of 30 mph to closer to 23 to 24 about 6 months ago. The dealership indicated that there are similar complaints that have been logged. The dealership further indicated that GM has issued an technical service advisory based on similar complaints.

I have a 2006 Chevy Cobalt purchased used with 28000 miles on it. All my problems started about a month after I bought the car. The steering wheel started shaking violently when driving at 50 mph and over so I took it in to a Chevy dealer and they rotated and balanced the tires and that seemed to fix that problem. About 2 weeks I was driving home and I was sitting at a red light and the car just shut off. I restarted the car and every thing was fine on the dash board, no warning lights or messages in the driver information center. I started driving again and when I press on the gas there was this loud grinding noise and it felt like the car was not shifting gears properly. So I pulled over on the side of the road and turned the car off for about 10 minutes and restarted it and it drove fine. Now at this point im just thinking that there is a malfunction in the computer. I took the car to the dealer the next day and they scanned the computer and found no errors and everything was checking out fine. About 3 weeks later I was driving on the highway and I lost complete control of steering and the power steering message in the driver information center was displayed along with the check engine light. Unable to steer I had to stop in the middle of the highway and shut the car off. I waited about 20 minutes and restarted the car and the power steering warning message and check engine light had gone away and I gained steering control again. I once again took the car to the dealer and they could not find anything wrong with the car. Now some days when I start my car the power steering warning message and the check engine light come on and some days the car drives fine and its really starting to frustrate me. In addition to the steering problem I am unable to remove my key form the ignition. To this day none of my problems have been resolved.

Power goes off after you shut the car off. You have to press the button in the trunk on the battery before it will crank. Power button for the trunk does not work. You can start the car and it will still keep trying to crank.

(1) car shuts itself off while I was driving down the freeway. During@ rush hour I veered away ( w-no power to car ),from traffic behind me. Parked, shut car off, took key out of ignition, then replaced and started it back up, and proceeded enroute. (2) after market cruise control failure to shut off and turn on. (3) result of above (2)after market cruise control takes its own mind and decides to fully accelerate until gearing down in hopes it 'awakes' the computer (automatic transmission),then cruise control will finally shut off. (consequence ) passenger had a heart attack. I called a taxi. "he's ok" (4) service air bags light have been on since 20, K miles I now have 47, xxx miles. (5)stock tires and rims wobble with irritating continous noises -can't ge rid of it. (6) stock seats driver and passenger sides both were installed incorrectlythey are really slantedlike this ( / \ ). (7) a clunking bucket sounding noise fills very slowly, (health problems) an odor is always present leaving me light headed, nautious while driving, dizzy exiting car, and with breathing problems -like shortness of breath. I have severe back problems now, and can not sit in the car for more than 20 min, upon a break of fresh air and a walk for the spine. (8) brakes sound and feel (when applied),scratchy.@5,000 miles the Chevy dealership had to turn and shave allready my disc brakes saying they were worn in. (9) my heater makes a lot of noises when using it. (10) acceleration hesitation.

- the contact stated that her 06 Chevy Cobalt experienced stalling incidents on several occasions. The vehicle stalled while driving at various speeds. The weather condition at the time of the incidents has been fairly warm. The contact has taken the vehicle twice to the dealership the first time was on 12/05/06 and they replaced the ignition switch. The vehicle still continued to have the same problem, so she took it to the dealership for a second time and the dealership replaced the kill switch. The contact can provide copies of invoices if needed.

I was driving my 2006 Chevy Cobalt when I was taking a friend to the airport. I was on I-495 N in the lane leading to the exit that takes you to the airport toll road. I applied my brakes and the car did not slow down. Hoping to coast down the exit and pull off to the side of the road, I turned the steering wheel to veer the car left. The car kept going straight. I kept hitting the brakes and turned the steering wheel to the left, but the car did not stop, nor did it turn. We crashed into the guardrail at about 50 mph. The airbags did not deploy. Turns out the car shut off while I was driving it. This was the second time this had occurred. It happened back in May 2006 and I took it in to the dealership. They kept it for a couple of days and said it was fine. Apparently not.

2-incidents of sudden acceleration at freeway speeds: The first time the cruise was activated and on hitting resume the car took off on it's own. The coast function did not slow the car and turning off the cruise did not slow the car. I was in fairly light traffic and was able to steer and brake out of trouble until the accelerator returned to normal[the brakes only partially slowed the car because of the high speed involved]. about an hour later I was entering a freeway and at about 40-45 mph the accelerator went to the floor on its own again and I had only partial control of the car's speed. The cruise was off this time and again after a few minutes and miles the engine revved down to normal on its own. Again traffic was fairly light so I was able to steer and brake through without a crash but in heavier traffic this would be a serious problem. The dealer test drove the car for about 18-miles but could not replicate the incident which is random and intermittent and their diagnostic tests showed these incidents never happened but believe me this is a real problem when these computers or electronic systems malfunction. General Motors has opined that this is impossible which is a cover up since everything is controlled electronically. This is particularly dangerous since it happens at freeway speeds and the pedal goes to the max.
