Owner report 11553141 · 2023-11-02 (November 2, 2023)
While driving our Lexus on 8/13/2023 on the interstate under normal driving conditions ALL of our warning lights came on one after another. We also lost air conditioning and power brakes it seemed. We immediately exited and pulled over. Opened the hood and the engine caught fire and fully engulfed the engine compartment. From the time of the first warning light to the vehicle being engulfed was probably 5 - 7 minutes. The vehicle was deemed a total loss. We filed a product liability claim with Lexus/Toyota and they investigated the vehicl…

Owner report 11594768 · 2024-06-17 (June 17, 2024)
I am writing to express my deep disappointment with the service I have received regarding my 2021 Lexus NX 300, which I purchased pre-owned in October 2022 with approximately 8,000 miles. I trusted in Lexus's renowned reputation for luxury, dependability, and premium comfort. However, my experience with your service department has significantly diminished that trust. Since my initial report of a recurring issue with the braking system on [XXX], 2023, where I heard a cracking sound in the tire and brake area as if the brakes and wheels were abo…

Owner report 11730073 · 2026-04-08 (April 8, 2026)
My vehicle has slowed while driving four times within the last 12 months. I have taken it to the Hendrick Lexus dealership in Charlotte as well as the Scott Clark Toyota dealership in Charlotte. I was told by the Lexus dealership they could not find anything wrong (this was back in July 2025). The Toyota dealership stated (March 2026) that there may be a problem with the fuel pump, but they were unable to confirm this issue and after getting the vehicle back the same thing happened while driving. This has been concerning. It is very dangerous f…
