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.

Passenger seat occupancy module - failure the failure of an electronic module located under the passenger seat, defaults the airbag system to "off". cost is just under $1,000 for dealer replacement. Dealer indicated there was no method to turn on the airbag system - regardless of passenger or not. Because of this failure (many failures recognized since the 2006 solstice model) any passenger is subject to an unsafe condition without active airbag. The value of the vehicle negates the dealer cost to repair. Complaint filer feels the cost of the replacement module should be half of that quoted by the dealer since genuine GM parts are available at $275 instead of dealer cost of $417 and that labor of 2.5 hours to replace module under the seat is excessive based on time taken by others self-correcting the problem. (times indicated ran from 20 minutes to 45 minutes for most). Because of costs, many of these modules will (likely) go un-repaired and potentially un-reported if sold as a used vehicle..

I have gotten a "airbag fault" warning every time I start my car. Apparently this is due to a censor giving out and to repair the issue costs about $1000. This is highly unsatisfactory as many users of this particular vehicle have reported this issue when operating this type of vehicle under normal conditions. This in a sense renders the vehicle unsafe to operate as drivers (some unaware), whivh I was not, are operating the vehicle without any operable airbags. The cost to repair is very high for a feature that is a safety standard across the industry. The airbag system of a vehicle should never have any faults or failures unless it has been deployed or tampered with. It is quite disappointing that a system that has never been used or tampered with can have such costly faults/failures. This is an issue that needs to be addressed immediately. This is scary. I feel like some thing needs to be done to fix the problem. GM needs to recall the module that will fix this issue asap. This air fault is putting many families at risk of loss of life!!! bring attention to this issue or to what is causing it.

Rear passenger door and drivers door are not locking with remote key or electric power door switch. This began with only the passenger rear door but has migrated to drivers door as well. This problem could lead to theft of internal contents and worse, vehicle robbery.

The key fob contains the ignition key and unfolds with a button press, but the spring mechanism holding it open is a bit weak. When you have it attached to a key chain, the weight of the keys can fairly easily make the key fob fold over in an "L" shape with the key in the ignition. This happens while driving often, and being 6 ft 1 in tall, my knee bumped the keys while I was putting my foot back and forth between the gas pedal and on the brake. Due to the folded over key fob attached to the key in the ignition, there was enough leverage placed on the ignition switch, turning the ignition to the off position, and the car shut off while rolling along in heavy traffic.

After putting the vehicle in park, the key will only turn halfway. This results in the key being stuck in the ignition. This occurs intermittently, but tends to get worse the more frequently the vehicle is driven. Only way I have been able to remove the key is to turn the vehicle back on and rotate thru the gears. Sometimes it takes 5 or 6 tries. Also the side view mirrors will not operate all the time either and according to the dealer, the mirror and the key ignition run thru the same wire harness in the shifter mechanism. I have taken the vehicle to the dealership 2 separate times. The first time they could not mimic the situation, but the second time it happened 5 times after 3 days of testing. This condition appears to have happened to numerous customers based on info I have read on the internet. I am working with GM to get this resolved but I believe a recall should be at least investigated since my vehicle is only 2.5 years old and others owners have had a similar condition occur. To correct the problem the dealer is replacing the floor shifter and the wire harness. Not sure if this will work but hope so.
