“I was involved in a side collision accident and my car was determined to be total loss by the At-Fault's insurance company. I was lucky that my son and I came out with bruises and a few scratches but the main problem here is the airbags. It DID NOT deploy at all when it was hit. The force hit us from lane 1 all the way to lane 3 and damages to the structure near cabin was found by one of the vertified accident body shop. So yes, no airbags were deployed.”

“My car has an oil leak from the timing chain cover gasket that was discovered by an independent mechanic at 37,465 miles. The dealer confirmed the leak on June 14, 2024 during a recall replacement of the fuel pump. The repair is very expensive and the car is no longer under warranty. This is the second occurrence of this same issue. The first occurred in April 2021 at 24,192 miles and was repaired by the dealer under warranty. There were no warning lamps or messages of the problem but there was oil on the ground where I park. The car is available for inspection. An internet search confirms that this is a known and common problem with the Lexus RX350 (and specifically the 2017 model) for many owners with some occurring more than once as in my case.”

“On [XXX], my wife, [XXX] , was driving our Lexus RX 350 when she noticed engine smoke without any prior notifications from the vehicle. Concerned for her safety, she pulled over and contacted Geico for assistance. Geico arranged for the vehicle to be towed to Motor City Lexus, a trusted Lexus dealership in Bakersfield. Once we the dealership performed a diagnosis they advised that the issue involved coolant being leaked into the engine that caused the smoke with in result caused the engine blow head gasket. After doing some research I saw an article from consumer reports about some Lexus and Toyota SUVs doing the exact same thing which made me decide to wrote about this incident. I am including the link regarding the report [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)”

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

“My vehicle is experiencing a mechanical failure of the brake actuator/booster assembly, manifested by a "squawk/bark" noise and abnormal pedal feel during braking. This is a known defect recognized by Lexus under Customer Support Program 23LE04. The dealership technician confirmed the noise is present and recommended a full replacement of the ABS actuator. However, Lexus is denying coverage because the onboard computer has not yet triggered a Diagnostic Trouble Code (DTC). By denying the repair, Lexus is requiring me to operate a vehicle with a confirmed mechanical brake malfunction, which increases the risk of a crash, increased stopping distance, or total brake power assist failure. March 2021 (60k miles): Actuator was replaced under warranty for this exact failure. December 2021 (74k miles): The failure recurred. Lexus and the dealer refused to cover the diagnosis/bleed, forcing me to drive a defective vehicle. February 2026 (110k miles): A Lexus dealer confirmed the part is failing again and quoted $3,000 for replacement. Despite a manufacturer program (CSP 23LE04) existing for this exact part, Lexus refuses to honor it without an electronic code, even though the mechanical failure has been physically confirmed by their own technicians. The component is available for inspection.”
