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.

2007 Volvo S40 Owner Comments

problem #1

Feb 012007


  • 3,000 miles


The contact owns a 2007 Volvo S40. The contact stated that her vehicle feels as if it were downshifting; however, it has an automatic transmission. When she begins to accelerate, the reduced engine performance light illuminates when the downshifting occurs. The dealer replaced the accelerator pedal and cleaned the computer after the first failure. After the second failure, they replaced the computer. The failures still persist and the contact is scheduled to take the vehicle to the dealer next week. The speed was unknown. The failure mileage was 3,000.
