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.

Vehicle check engine light, stability control assist, and cruise control light come on all at the same time rendering those system useful. Also sometimes the hill start assist and ABS light come on rendering those unavailable as well. Making the vehicle not as secured as advertised. It started in 2010 took it to the dealership and they just erased the codes, but the problem continued, still happening today.

The fire wall is cracked and the welds are broken which is causing my clutch to not disengage properly and the clutch pedal to not function correctly.

The contact owns a 2008 Subaru Impreza. The contact stated that while exiting a drive-thru, the vehicles exhibited a loud bang and the vehicle immediately accelerated abnormally. The contact attempted to apply the brakes, but there was no response causing the contact to crash into a tree. The contact was severely injured and was taken to the hospital. The vehicle was destroyed. The contact was told that the throttle had erroneously opened fully and would not close, causing the vehicle to accelerate abnormally. The failure and the current mileages were 20,000.

Vehicle started with a noise in the clutch pedal. Went away with lubricant. Then began to make a clicking sound and the clutch and brake both started to move as I depressed the clutch. The shifting of gears became difficult from the start of reverse or first gear. Then it be came real loose I had a mechanic look into it and mentioned that a weld has broken and did not recommend him fix but to have the dealer take a look at it because its a safety issue and if it breaks completely that it may cause the car to be unable to stop. So I took it to the dealer and mentioned it was out of warranty. But they will look at it. Currently they mentioned they cannot fix it under warranty so currently I cannot afford to get it resolved so im unable to drive the car.

2008 Subaru Impreza, standard transmission. At speeds under 10 mph, when clutch is fully depressed, and transmission is in first gear, engine will rev up to 2500-4000 RPM's. this only occurs when vehicle is coasting forward at slow speeds and when in gear with clutch pushed to the floor. When brake is tapped or gear placed to neutral engine will return to normal idle. This problem occurs 90 percent of the time when coasting forward. The engine speed varies each occurrence but general speeds to around 2500 RPM's with rare jumps to 4000+ RPM's.

The contact owns a 2008 Subaru Impreza. While driving the vehicle would accelerate for a half second without pressure being applied to the pedal. The contact took the vehicle to a dealer. The dealer informed the contact that the accelerator pedal was designed for a half second acceleration. The contact took the vehicle to a local mechanic and the local mechanic informed the contact that the ECU needed to be reprogrammed. The contact has not had the vehicle repaired. The failure mileage was 255. Updated 03/11/10 while driving at any speed the vehicle would continue to accelerate as though the accelerator pedal was engage for up to 1.5 seconds after the consumer had removed his foot. The dealer informed the consumer the vehicle was performing within design specifications. The consumer went to two independent mechanics who stated the ECU that controlled the accelerator pedal behavior would need to be re-programmed. Updated 07/26/10
