2024 Lexus Es

The vehicle's speedometer shows an inaccurate reading, up to 7MPH less than the actual speed. This has been verified multiple times, measured against WAZE and a speedometer app. At lower speeds, i.e., less than 30MPH, the divergence between the speedometer and the true speed is 1-3MPH. At medium speeds, between 40-60MPH, the divergence is 5-7MPH. At highway speeds, the speedometer initially shows the same larger divergence but after several minutes starts to converge to within 1-2 MPH of the apps. The convergence disappears shortly after the vehicle slows down. The vehicle was brought into the dealership for repair but they said nothing was wrong. At that time, I was provided a loaner vehicle of the same make and model, and its speedometer matched WAZE perfectly at all speeds. I then contacted Lexus customer service, who opened up a case number. I uploaded photos and videos to Lexus documenting the problem. Lexus has now advised me by telephone (representative was "Israel") that they have closed the case based on what the dealer said, and further, that they will not recognize or rely on a third-party application such as Waze. They refused to provide me with an email or letter confirming this; all I have is a screenshot of the Lexus support platform showing the case has been closed. I believe this is a serious safety issue, and I am shocked that Lexus refuses to acknowledge or repair this. I have attached the photos provided to Lexus, screen shots of the two Lexus support cases, both stating "case closed", and the Lexus dealer invoice showing that the problem was brought to their attention (page 3 of the invoice). I am unable to upload the videos (2 x 1 minute long, one on a city street and one on an interstate) as they are larger than your system allows. If you can provide an alternate method to upload them I will be happy to do so. The vehicle is available for inspection and testing at your convenience. I hope your agency can assist with this issue.
