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.

I took my 2009 Chevrolet Cobalt 1lt sedan to the dealership from where I purchased it from today to get my vehicle inspected as required per my state. Prior to today, for about the past week or so, my check engine light came on. Went to autozone and they ran a diagnostic on it saying a cam shaft position sensor needed replacement. Replaced it and check engine light went away for about a week then came back on. (replaced both of the sensors to be safe) check engine light would turn off for days then randomly come on. Went to dealership and they stated I needed a new front right strut since mine's was leaking. Called up a few other mechanics and they have said this is a common issue with Cobalts. If you google "Cobalt strut leaking", there are many results, yet no recall. This isn't just common in my vehicle's model year but with all Cobalts. I feel there should be a recall since this is common among this make/model.

The key will not turn in the ignition cylinder. Therefore the car will not turn off. There is a special bulletin #10256 about this exact problem including only the 2009 Cobalt however as there is not an open recall the manufacturer will not repair my car because my car has a branded title and they will only repair 'open recall' items. This issue is not listed in the global database when my VIN is searched but it needs to be listed under my VIN and there needs to be an open recall on this issue because it is certainly a huge safety problem that many owners have been experiencing. The only way to turn the car off is to get under the hood and remove the fuel relay fuse. In case of a fire this would be a catastrophic safety issue which could result in serious injury or even death.

I own a 2009 Chevrolet Cobalt and have been experiencing a significant rumble when the car is warm and in gear. The car has been taken to an authorized Chevrolet dealership and they will not correct the problem, although my personal mechanic has been able to replicate the problem. I complained to General Motors and they refuse to handle the case. Their only response is to suggest that I trade the car in for a Ford and contact my attorney.
