Air bags

4 reports2 crashes
“The contact owns a 2013 Lexus RX450H. The contact stated while driving at an unknown speed, the contact had crashed into a tree which resulted in the airbags not deploying. The contact does not remember anything between driving on the highway and waking up in an ambulance. The contact sustained shoulder, neck, and mild concussion and sought medical treatment. The vehicle was towed to a tow yard where it was awaiting diagnosis. The manufacturer was informed of failure and the contact was awaiting a response. The failure mileage was approximately 105,606.”

Electrical system

3 reports1 fire
“Odometer Fraud: The contact purchased a 2013 Lexus RX 350. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 96,575. After reviewing an AutoCheck report by Experian the following day, the contact became aware that the mileage was 151,219.”

Structure

2 reports1 fire
“Vehicle was parked, engine off, and unattended. An internal electrical fire originated in the overhead/sunroof wiring area. Damage includes melted wiring harness near the sunroof, burned center console, and soot throughout the interior. The fire originated in a constant-power electrical circuit and spread downward into the cabin. There were no aftermarket modifications, no external heat sources, and no objects in the vehicle that could have caused ignition. Ambient temperature conditions were normal and insufficient to cause this damage. This represents a serious safety defect because the fire originated spontaneously within the vehicle’s electrical system and could have resulted in a full vehicle fire or injury if occupants were present. The failure appears to involve factory-installed wiring/components and is not consistent with normal wear or external factors.”

Steering

2 reports1 crash
“While my daughter was driving at about 1:15 PM in a residential neighborhood, the steering wheel suddenly jerked hard to the right and locked while in motion. This caused the vehicle to crash into a parked car. After the vehicle was towed home, the steering wheel remained locked with both front tires pointed sharply right. When I restarted the vehicle, the steering wheel immediately spun right on its own and locked again. It could not be moved manually, and the front tires stayed stuck in the fully turned position. This appears to be a critical steering system failure. It presents a severe safety risk and could easily result in serious injury or death. Note: I had the car towed home immediately after my daughter informed me of the incident. She reported the accident to AAA Insurance at that time, and the adjuster later indicated they wanted to tow the car for evaluation and a possible total loss settlement. However, I would keep the car at my home for inspection and can reproduce the issue if you let me know when you are available to come out. There were no warning signs prior to the failure, and the car had just passed a smog check a few weeks ago. I just made…”
