The transmission is jerking at times and it failed to accelerate at one point after coming to a complete stop. Notified Lexus and still working to fully resolve the issue but they just denied my request to reevaluate the issue.

Battery drains which locks car unexpectedly. No warning, even with car FOB inside car which creates a safety issue if child or someone is in the car. All doors lock and with no access to FOB cannot open the door with manual key. Also, safety issue if this happens at night or in a parking lot etc. Cannot open doors at all - There is obviously an issue with the battery draining after only a few days. Dealer solution - plug in a battery maintainer - problem if you are parking the car at an airport for multiple days. No place to plug the car in... Lexus needs to figure out what is draining the battery or some fix to stop this from happening - I drive my car several times a week 30 miles at…

The vehicle exhibits a severe, load-based mechanical transmission whine strictly during active acceleration. The pitch of the whining sound rises and falls in direct proportion to the engine's RPMs. This vehicle utilizes the Toyota/Lexus 8-speed automatic transmission architecture, which has a well-documented manufacturing flaw involving internal bearing wear, gear misalignment, and fluid starvation.This mechanical defect poses an immediate and severe safety hazard. The continuous internal wear and gear friction create an unpredictable risk of sudden transmission lock-up, unexpected dropping out of gear, or complete engine stalling while operating at high highway speeds. A sudden loss of…

While driving on [XXX] in [XXX] with my young child in the vehicle, my 2023 Lexus RX 350 F Sport suddenly lost acceleration. The vehicle initially would not accelerate beyond 50 mph and then progressively lost power, eventually being unable to accelerate beyond 40 mph. This occurred during rush-hour traffic, with vehicles traveling faster than me and passing closely. I attempted to move farther onto the shoulder because I felt unsafe being so close to traffic, but the vehicle became completely unable to drive. I had to stop and attempt to determine what was wrong with the vehicle. There were no warning lights, dashboard warnings, or notifications through the Lexus app before or during the…
Aug 8, 2026Visibility/wiper
The rain-sensing wiper system in my 2023 Lexus RX has been inoperative since I purchased the vehicle in May 2023 (current mileage: approximately 55,000 miles). The automatic wipers consistently fail to activate in response to rain, requiring manual operation while driving â a dangerous distraction that significantly reduces safety, especially during heavy rainfall when visibility is already compromised. This defect has been present since the day of purchase and is therefore a manufacturing defect, not a wear-and-tear issue. Lexus has since officially confirmed this through TSB L-SB-0025-25, which specifically addresses rain-sensing wiper failure in certain 2023 RX models. The vehicle is…
