“I was at the gas station, in line waiting for one of the three gas pumps to be available. I put my car in reverse to back up and pull around another car in order to go to the open pump in front. When my car was in reverse motion, I stepped on the brake pedal, but the car did not stop. I stepped on the brake pedal numerous times, but the brake did not function. My car backed into the front of the car in line behind me damaging both vehicles. The automatic emergency braking system did not activate, and there was no rear collision warning sound or message. I switched my car from Reverse into Park to stop its movement, but it was too late to avoid the collision. I had a passenger in my car who corroborates this description. Fortunately there were no pedestrians behind my car, so the only damage was to the vehicles. My vehicle has not been inspected by anyone since the accident, but will be soon. I have owned this car since April 2021 and previously had a few similar situations when moving in the forward direction. Previously, the brake problem occurred while moving forward at very low speed pulling into parking places. The brake failed to activate, and I had to…”

“Electronic Parking Brake (EPB), 12V Battery/Electrical System. My vehicle's 12V battery failed, with the dealership measuring voltage below 10V during the event. This caused multiple simultaneous module malfunctions (confirmed by the dealer as caused by the battery failure), including a complete inability to move the vehicle after jump-starting on three separate attempts — the engine ran, but the vehicle would not drive despite a functioning alternator. The vehicle's steering wheel also locked, preventing the car from being pushed to a safe location. Approximately 3 months after this event, a routine service visit revealed the rear brake pads had worn from 8mm (measured at time of purchase) to 2mm (failed), while the front pads wore from 10mm to 7.8mm (normal wear) over the same period and mileage. The rear pads wore roughly 3 times faster than the front, which is inconsistent with normal vehicle operation, since front brakes handle proportionally more braking load and are fitted with larger rotors for this reason on this and virtually all vehicles. The rear brake caliper is the only caliper equipped with the EPB motor/actuator; the front calipers are purely…”

“Brake actuator failed with exact symptom in [XXX] Repaired in dealer and the same symptom comes back within 2k miles. It seems a design flaw that affected many lexus rx hybrid and toyota highlander hybrid cars, and likely due to air being trapped in the brake lines or brake actuator components. Air in these system is a major safety hazards. Please help to make it a recall and ask Toyota to come up with a solution that really solve this issue. Similar experience from many other owners. One forum thread is attached here for reference. There are many more. [XXX]”

“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.”

“Component or System That Failed: The rear passenger seatbelt on the right side of a 2021 Lexus RX 450h malfunctioned during a collision. It is still in the vehicle, which is available for inspection upon request. How Safety Was Put at Risk: The seatbelt failed to restrain my son, who was seated in a booster seat and weighs approximately 78 lbs. During the collision, he flew forward and struck the front passenger seat and center console with his chest and upper abdomen. This malfunction could have caused severe injuries, and while his injuries appear minor, it posed a significant risk to his safety. Problem Reproduced or Confirmed: The seatbelt’s failure has not been reproduced or confirmed by a dealer or independent service center. However, the seatbelt remains fully extended and does not retract, indicating a potential defect. Inspections Conducted: The issue has not yet been inspected by the manufacturer or a service center. Police were present at the accident scene but did not specifically inspect the seatbelt. Warning Lamps or Messages: No warning lamps, messages, or other symptoms indicated a problem with the seatbelt prior to the collision. Best…”
