There are 1 owner-reported brakes complaints for the 2023 Lexus NXin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
My concern is regarding the auto start-stop feature. It is a concern since the feature is tied to both the brakes and engine, and it could lead to other/bigger issues. When stepping on the brakes to come to a stop, sometimes the auto start-stop feature turns on. Upon releasing the brakes, there is a loud grinding noise. I brought it to the dealer twice for this issue. The first time a master technician got in the car with me, he drove it and he was able to reproduce the sound continuously, at least 10 times. I left my car with them for a week and was told they were never able to reproduce the noise again. I brought my car home and drove it for 5 days and then it started making the noise again. I took it back to the dealership and they kept it for another 5 days. I was told again they were not able to reproduce the noise. There have been no warning lamps, messages or other symptoms of the problem. As background, I purchased my car in April of 2023. The noise started in January of 2024, with less than 6800 miles on it. It happened off and on and it took a few weeks for me to realize the noise was tied to the start-stop feature. Once it became more prevalent, that is when I finally called the dealership to explain the issue and got an appointment to take my car in on 2/19/2024. I currently don't have videos to attach but can follow up with videos in the future if needed.
