What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My tundra was parked and it started to row down the road no body inside end it up on neighbors drive way hitting a tree total loss I believe is brake related issue
The contact stated that the steering wheel was shaking and corroded. The contact stated that the vehicle was taken to a dealer for the failure and the technician crashed the vehicle. The details of the crash were unknown. The vehicle was taken back to the dealer but was not diagnosed or repaired.
I struck the animal broad side with the front end of the truck knocking it into the engine bay. Initially I thought the contact was not severe but inspection proved otherwise. The hood was crumpled up unto the windshield, and the radiator and motor was pushed so far back that it was no longer drivable.
However, the side impact air bags did not deploy, which should have happened. The truck is still in the shop as of 9/25/13 because there are problems with the onboard computer recognizing the side air bags. I am concerned with the safety of the vehicle air bag system. Updated 1/6/2013
The contact stated that while driving 35 mph and towing a trailer, the vehicle started to vibrate as the front passenger side tire exhibited an abnormal grinding noise. The contact mentioned that the traction control warning light was illuminated, causing the tires to seize.
The contact turned off and restarted the vehicle, and the fuel leak stopped. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the fuel tank valve assembly needed to be replaced. The vehicle was repaired; however, the failure persisted.
Wife was driving truck and immediately went into limp mode on the highway. Check engine light came on, no accelerating then died. Had to get it towed. This is the 3rd incident with this issue.
The fuel pump failed on my Tundra. Several dashboard check engine lights suddenly lit up to warn me of the issue. While I was able to safely get it to a mechanic to repair the independent Toyota certified mechanic I use shared they have seen a volume of these where the car stops immediately with the Fuel pump failing…
