What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The air bags failed to deploy. The air bag malfunction warning light was illuminated. The contact did not sustain any injuries. The vehicle was towed to a tow yard. A police report was filed. The vehicle was not diagnosed or repaired by an independent mechanic or dealer.
The tire poses serious and immediate safety risk of sudden failure, especially in rain, creating danger of a blowout, loss of control, or vehicle damage. I need to replace the tire immediately for safety. If your office requires inspection, please notify me as soon as possible so I can retain it.
225/50/18 Tires have less that 2000 miles on them and they are pealing at the treads. Literally whole chunks are falling off the tires…looks like someone has been picking and pulling off pieces of my tires.
Tires came new with car in 2021. The two front tires are chunking. Back tires appear to be fine. Car is not out of alignment, has never been in an accident, no off roading or parking on gravel surfaces. Took it to a Lexus dealer and service rep. says he's never seen a car like this.
