What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I, my wife, and our children were all wearing seatbelts at the time of the collision. After an oncoming vehicle struck the front-left portion of my vehicle while making a left turn, my vehicle lost control and collided with a concrete pillar. None of the airbags deployed during either impact.
Airbags did not deploy How was your safety or the safety of others put at risk? Me, my wife & 4 small children were in the vehicle when it was struck - and none of the airbags deployed. Has the problem been reproduced or confirmed by a dealer or independent service center?
The contact had enough fuel to run the air conditioner. The tires were previously rotated. The contact stated that the situation could have been worse, and not having a spare tire puts the drivers in a dangerous situation. The failure mileage was approximately 11,474.
The airbag warning and the acceleration failure often appear together, which makes me believe there is an electrical or wiring problem affecting multiple systems. I also discovered that Toyota documented underbody impact damage from a pothole months before I purchased the vehicle.
The authorized Toyota dealership has declined warranty coverage for the air conditioning system. The unit exhibits intermittent cycling between warm and cold airflow on the highway. Although the control panel indicates a minimum temperature of 60°F, performance remains inconsistent; the temperature gauge reads 67°F.
Driver-side mirror (glass part only) vibrates while driving, no matter the speed. This causes a distorted rear view â for example, it's hard to read the license plate of a car on your left.
My rear lift gate was misaligned and gets stuck. The dealer just fixed and wouldn't honor the warranty, but I believe this shoddy build quality could impact the safety of my family in an accident as it didn't appear the hatch was properly secured
Upon closing the driver's door, the rear liftgate window exploded into the vehicle. This occurred without any warning or adverse action by myself or anyone else. The vehicle has been in no collisions, and has only 6429 miles on the odometer.
