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.

Between approx 45 and 60 mph vehicle sounds as if driving over rumble strips. Will stop vibrating intermittently above 60 mph. Vibration is felt from front passenger side. The steering wheel does not sway. No trouble shifting. Between 3 mechanics have been given 3 different answers: Loose body part vibrating in wind, suspension, transmission. Had balance and alignment checked with no issues. Contacted GM dealer to check recalls and other known issues, none found. No previous symptoms, vehicle drove normally until 6/18. Do not currently drive vehicle out of fear of something breaking or falling apart. Am still trying to get diagnosed.

Vehicle was being towed behind class a motorhome. Key was in the accessory position; transmission (automatic) was in the neutral position; fuse block:8 (ignition switch, pass-key III+) was removed to prevent battery drain; per vehicle manual for dinghy towing. Traveling on interstate 45; 95 miles South of dallas, tx. Nothing was hit when traveling. Both front tires blew out, subsequently ruining both front tires and wheels. There is no apparent reason why this happened. Was wondering if this may be connected with current safety recall on ignition problem on Chevrolet Cobalt. The key chain had three keys and the key fob attached.

Driving vehicle on highway when engine check light comes on and "reduced engine power" message appears on status bar of dashboard. Repaired at dealership by replacing throttle control body. Occurred twice more over next 3 days, repaired at different dealership saying first throttle control body was defective. Occurred again 2 days later, dealership replaced crankshaft position sensor. Occurred again 1 day later. Need to take in for more service. Basic internet research shows that this is common problem on Chevrolet Cobalts.

I just found out there was a recall on the 2009 Chevrolet Cobalt due to failure with the electric power steering assist motor / system. As I looked it up I found 2 additional recalls which Chevrolet was supposed to contact me on all 3. I was not contacted, and do not know if my car has had the repairs done prior to me purchasing the vehicle in January 2011. The 2 other recalls are as follows. Shifter cable problem with car not in proper gear, clip on cable, if not installed properly, Chevrolet is supposed to replace the entire cable. Also, a fuel leakage can occur, causing a fire, due to a plastic supply and/or return port breakage on the fuel pump module.

Why isn't there a recall for the 2005 Cobalt? this happened shortly after I purchased the vehicle! why do you have the recall only for 2009, it should be for 2005 and all models affected, regardless of the year! just picking one year is not accurate for this type of issue. This need to be fixed asap! please and thank you! "transmission shift position sequence, starter interlock, and transmission braking effect", and FMVSS 114, "theft protection and rollaway prevention". on some of these vehicles, the transmission shift cable adjustment clip may not be fully engaged. If the clip is not fully engaged, the shift lever and the actual position of the transmission gear may not match. With this condition, the drive could move the shifter to "park" and remove the ignition key, but the transmission gear may not be in "park".

I parked the car for the night with no indications of any problems and when attempting to drive the next day, the key would not turn in the ignition. Tried moved the steering column and it would not turn to start. Talked with a locksmith and was told that it wasn't the ignition but the power train column shift since neither of the keys worked. I spoke with the Chevrolet consumer hot line (1-800-630-2438) and was told that there was not a recall on my VIN. I assured them that I have a vehicle with 85,546 miles that I can't started with the first 11 numbers of the VIN recall.

Chevy Cobalt 2009. Two incidents involving the same model but different cars. Both rented from enterprise. Don't know what category to put the complaint in. Steering" braking? or something else" this model handles terribly on wet pavement. Doesn't brake well on wet pavement, and tires spin when starting from a stopped position. Incident 1. changing lanes on I270 md. Going about 50 mph. And slowed down to move one lane to the right. Going from a less used wetter lane to lane to the right, which wasn't quite as wet. Car spun out twice and hit the jersey wall twice. Then I was able to stop the car. Fairly heavy traffic, and no other vehicles involved, thank god. State police were on the shoulder for traffic going in the other direction across from me but did not come to the car. Incident 2. rented another of the same model. Whenever the street was wet, the car did not brake well. Seemed to be very short periods of not braking. When slowly starting from a stopped position, the wheels spun and then took hold. Could have easily been another situation for spinning out. Enterprise said there were no recalls. Insurance company raised my rates from $103 to $167 per month!
