Example complaints
Other or unknown: “When driving uphill on a local city street, where there was a metal plate in the road, my Lexus RX350, would detect the metal plate, and apply the pre-collision system. When I reported this issue to the dealership, they offered to shut off the pre-collision system as a work around. I was told that the system was working properly and that there was a warning about the potential for this to happen in the manual. I reported this issue to Lexus corporate as well. I could reproduce this issue and offered both the dealership and corporate to view the video. Both declined my offer. …”
NHTSA complaint #11045762, filed 2017-11, 32,934 milesEngine: “The push-button (keyless entry) ignition did not kill the motor. My car engine ran from approximately 6 p.m. In an enclosed garage directly below my bedroom. At 4:30 a.m. I was awakened by my carbon monoxide detector. The entire house was filled with toxic fumes. First responders to my 911 call said the detector definitely saved my life. I was a little dizzy and had a headache but was ok after awhile. It took nearly 3 hours for the first responders' co2 monitor to show safe air throughout my house. …”
NHTSA complaint #11302550, filed 2020-01, 44,000 milesFuel system: “Engine abruptly stops and I have a 3 second stall, then the car resumes normal operation. Could be a real serious accident without warning. This happened in motion on a highway from a stop light or stop sign or pulling out onto traffic.”
NHTSA complaint #11398045, filed 2021-02, 58,000 milesVehicle speed control: “Dynamic speed control randomly (twice) has lost settings & control. Setting it at 60, car increased speed to 85, and ignored car in front of me, almost causing a crash. Lexus has not followed up with me on this. Voice recognition often functions incorrectly resulting in distracted driving, and has almost resulted in me driving out of my lane or off the road several times. Example: ask it for directions to palo alto medical foundation: result; gives me a list of south american restaurants. Contacted Lexus about this. Only response - take it to a dealer. I have an appt with one july 11. …”
