“I was driving up a hill, turning on to a dirt road. I had my foot on the brake as I was going down hill, I bounce from the crevice on the dirt road. My car started going faster, I kept my foot on the brake trying to stop, but it did not STOP. I avoided hitting a parked car and slammed in to a K-rail. My car would not STOP.”
NHTSA complaint #11466093, filed 2022-05“3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard. Tried sending photos but it didn’t work.”
NHTSA complaint #11675681, filed 2025-07“I purchased a 2017 Lexus Rx 450h Fsport last year at Carmax. About 6 months ago, I noticed that every time I pressed the brakes, there was a chirping sound. I figured it could be dust in the calipers. As the months went by, the chirping sound has gotten louder and now it affected the parking brakes. I researched this problem and many people online have also complained that they are hearing this Chirping sound or what the Dealer calls a Brake Squawking sound. I received a letter from Lexus saying to bring my vehicle in for a possible Brake Booster and Fuel pump failure. …”

NHTSA complaint #11733292, filed 2026-04, 59,380 miles“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). …”
