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.

2009 Toyota Highlander was involved in the floor mat recall. When vehicle was taken to dealer and consumer was told there was nothing they could do because the floor mats were not Toyota floor mats. The consumer stated at times the vehicle would not start. The dealer performed a diagnostic test and stated the battery was weak.

Highlander 6-cyl

  • 7,000 miles
Accelerator stuck all the way to floor on 2009 Toyota Highlander while vacationing in Tennessee on I40. Had to weave thru traffic to shoulder while traveling towards 100 mph, mashing full force to the floor all the time during incident. Very frightening. Car is presently returned to dealership, but no action has been taken & they can't find "anything wrong." I am afraid to drive the vehicle now. This was a life threatening event, but I don't feel Toyota is treating as such. I am trying to find some help as to what to do. It has only happened once, but there could have been serious consequences to both my husband and I and for other vehicles on the road. The consumer has since traded the vehicle. Updated 04/05/10
