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.

1. the events leading up to the failure. None 2. the failure, how often it occurs, and its consequences. Periodic uncommanded changes in throttle. Dealership test equipment shows evidence of data corruption on channel 1 of the two channel throttle position sensor (tps) occurring every couple of seconds. Driver perception of problem is in form of jerky throttle response at low throttle with one instance of sudden, uncommanded acceleration. The sudden throttle changes have resulted in traction loss on slippery roads severe enough that the vehicle departed the roadway. 3. what was done to correct the failure; I.e, parts repaired or replaced (and if old part is available) dealership replaced throttle body, wiring harness, and engine control module in an attempt to resolve tps data corruption problem and drivability problems, but was not successful in their pursuit. Dealership requested assistance from the manufacturer's field engineering team. A field engineer was dispatched, evaluated the vehicle, declared that it was "operating within manufacturer's specifications", and told the dealership to ignore what their test equipment was telling them. When requested to provide the specifications, what tests where performed to determine compliance, and the results of those tests, the manufacturer refused.
