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
