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.

The contact owns a 2008 Chevrolet Uplander. The contact stated that while driving at 65 mph, the vehicle lost power. In addition, the accelerator pedal was depressed but the vehicle failed to accelerate. "reduced power" was displayed across the message board. The failure recurred on numerous occasions. The vehicle was taken to a dealer, who diagnosed that the throttle position sensor needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 110,000.

The first thing that I noticed was the warning system posted "stability system error". while driving on the highway, with my foot on the accelerator, the brake depressed with some agitation of catching or jerkiness. This has occurred multiple times with no real pattern of consistency.

I have noticed right around the time I got this van that just it just started making this clunking sound coming from the rear end and making a noise that I couldn't figure out. The drop down modular has been really bogging down around 50mph and makes me give it more gas to stop the kick back. The engine light came on after buying a set of 4 new tires for the van. I bought what the van recalled and the check engine light came on and wont go off. I have had it checked out and still wont shut off. I have kept the oil changed at required times. I noticed the fuel system also has been giving the van a harsh mpg issues and not sure why. I think it might be the drop down modular that is causing this problem. I now been having since 2011 the clunking sound coming from the rear end axel area and then after reading about the recall today really made me scared to drive this van because I'm disabled and in a wheelchair. I have the lowered floor option and I know its going to need this recall fixed and welded. Please send me a email on how I can get this van fixed. I wanted to also tell you that this van was sold to me at $32,850 and had a blown engine that they didn't tell me till afterwards. At 20,000 miles the van blew up and they sold it to me as new and it was used. They also tried to sell me a extended warranty that was paid for by the manufacture for $3,500.I feel I was done wrong and would not of bought this van if I had known it was blown up at 20,000 miles. I would like to request a review to have it inspected and fixed with the welding that the recall calls for. Thank you.

I've been having problems with my 2008 Chevrolet Uplander van which is equipped with the Chevrolet "drive by wire" throttle. The throttle body was replaced in January of 2011 and continues malfunction. (3-years after original owner purchased) I have been taking the van to local area service stations to have the throttle body flushed every six months but continue to have reduced power issues. After calling the GM customer service number (866-790-5700 X20305) and explaining & having a file opened, I was informed that I was required to bring my van to a local dealer to have the issue diagnosed. The dealer diagnosed a faulty throttle body and the customer experience manager informed us that there is nothing the dealer can do to compensate this obvious design flaw which causes reduced engine power and causes the vehicle to operate at an unsafe speed and manner. I wrote the customer assistance center (cac) hoping that there are other processes that GM corporate office has in place to address issues such as these. My next step was to contact the National Highway Traffic Safety Administration vehicle safety hotline to determine any available resources.
