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.

2006 Toyota Highlander Owner Comments

Highlander 4-cyl

  • 68,970 miles


My wife was driving our 2006 Toyota Highlander. She drove approx 1/2 mile from our house at an average speed of 35 mph when the temperature gauge suddenly went past the red line. We had our car towed to crown Toyota where they tore down the engine and found water pump leaking and head gasket leaking oil. They removed engine head and found warped block and but head was okay. We then towed the Highlander to a private mechanic to have block replaced and we were informed the block was not warped but instead the bolts on the engine are stripped/defected. Toyota wants $5,400 to repair vehicle by installing a used engine. Toyota refuses to help with the cost even though it appears to be a manufacture defect and has already charged us $654 to diagnosis the problem and did not even reassemble our engine. The car was no longer under warranty at 68,970 miles. We have not yet repaired the problem.

Highlander 6-cyl

  • Automatic transmission
  • 140 miles
Toyota Highlander hybrid-I have lost ABS brakes, stability control and power steering along with the hybrid engine on two occasions with my 2 week old 2006 Highlander. I have brought it to the dealer twice-the first time they found "malfunction codes" and "rebooted" the computer and told me it was operating as "designed, " only to happen again 2 days later. Currently, they are replacing a computer. Date of incident and purchase of vehicle is actually 2006 but is not an option below. I am concerned it will happen again and result in an accident in the future.
