Dec 5, 2024AirbagsDriver assistanceCrash

Hit a deer that impacted the passenger side of the vehicle. Passenger seat was occupied, and door had to be pried open by tow truck driver to get passenger out. Entire right side, from the "L" logo to the front fender was destroyed. The passenger airbag did not deploy, nor did emergency braking or collision avoidance warning go off as deer was crossing from the left (driver) side to passenger side where it impacted. No injuries, but car had to be towed due to front damage. Lexus has no fix for the airbag sensor recall for almost a year now.

I was driving on the freeway in Stockton California and I entered into a connecting on-ramp curve going about 30mph and a lady hit me from behind on the passenger side going 65mph as she was trying to change lanes to get behind me and my car instantly speeded up spinning out of control Into a gully filled with stored freeway construction materials such as poles . The car kept spinning out of control because the ground was mud-slush from the rains. I kept construction poles came into my windshield, I kept spinning and sliding as I slammed into 2 trees and as the car sustained severe damage all over the vehicle and I kept slidding landing over in a second gully on the opposite side of the freeway. No airbags deployed no sensor went off nothing. I was in the car with my autistic daughter. The car is brand new. I contacted Lexus filed a claim and they sent me letter they don’t want to tak responsibility for their product liability

1.) My SUV locked up when I swerved to avoid hitting a car in front of me. 2.) My vehicle wouldn't stop and I had no control over it as it "threw me around" the highway. The only reason it stop was when it collided with another vehicle. 3.) It is sitting at the collision center right now waiting to be worked on. 4.) The insurance adjuster. 5.) The message that came on was "brake."

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Lexus Rx450h verdict →
