The records describe a problem worth checking before purchase.

“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”

The records describe a possible fatal outcome.

“Motor Vehicle accident with damage to vehicle front end and drivers side quarter panel. Vehicle was not drivable and required towing service at the scene. Front seat belts of the vehicle failed to engage resulting in the driver being bounced up in the seat and then down resulting in a serious compression fracture of the vertebrae of the spine. An inspection was completed of the vehicle by a third party and reported to the Toyota Claims department on August 19, 2022. Toyota did respond with notification related to the results of the inspections to include: "The seatbelts were found to be operational. The front drivers' and passengers' seatbelt ELR (Emergency Locking Retractor) were tested and found to be operational. The EDR readout recorded that the drivers' and passengers' front seat belts were buckled at the time of the incident, and the seat belt pretensioners were not commanded to deploy. The owners manual advises that the pretensioners help the seat belts to quickly restrain the occupants by retracting the seat belts when the vehicle is subjected to certain types of severe frontal or side collision or a vehicle rollover." The owners manual related to seat belts on page 28 also documents that "the pretensioners do not activate in the event of a minor frontal impact, a minor side impact or a rear impact." NTSB Safety Alert SA-005 July 2012 documents "What can you do to save lives and reduce injuries? Make sure seat belts are worn by everyone in your vehicle and talk to your state and local lawmakers and urge them to support NTSB recommendations for seatbelt use laws." Why encourage all to use seat belts if they do not engage in the event of an accident and the general public believes that the seat belt will engage in the event of an accident, again to help prevent not only death but serious injuries... Al Law related to seatbelts, section 32-5B-4; Requirement of front seat occupants of passenger car must be fastened about body when car is in motion.”

The records describe a possible crash, fire, injury, or loss of control.

“Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Avalon, Avalon Hybrid, Corolla, Highlander, Highlander Hybrid, RAV4, RAV4 Hybrid, Lexus ES350, Lexus RX350, Lexus RX450H, 2021 Sienna Hybrid, Lexus ES250, 2020-2022 Camry, Camry Hybrid, and ES300H vehicles. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying. An air bag that does not deploy during a crash increases the risk of injury. Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 23TB15/23TA15 Lexus 23LB03/23LA03.”
