2023 Lexus RX

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 least - still happens. Have had to replace battery twice so far.

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 motive power on a fast-moving highway leaves the driver completely unable to accelerate out of harm's way, creating an imminent risk of a severe rear-end collision or a catastrophic traffic accident. The manufacturer has failed to issue a safety recall for this known powertrain failure."

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 incident. I had driven approximately 200 miles that day and had not noticed any unusual noises, odors, and nothing sounded abnormal prior to the failure. The vehicle had been regularly serviced every 5,000–10,000 miles. Its most recent service was in late March 2026, four months before this incident, and I was not informed of any transmission problems at that time. The vehicle had 80,000 miles at the time of the failure, and the scheduled transmission service/check was not due until 90,000 miles. The vehicle was taken to Lexus for diagnosis. Lexus determined that the transmission needed to be replaced and is holding my vehicle as transmissions are on back order. Lexus has agreed to cover the replacement transmission and is charging me $1800 for labor costs. I am reporting this incident because the sudden loss of acceleration and eventual complete loss of the ability to drive occurred while traveling on a freeway with a child in the vehicle and surrounding traffic, creating a significant safety concern.

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 — 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 available for inspection upon request. Rather than visiting a dealership, I filed a complaint directly with Lexus Customer Care after discovering through owner forums that multiple dealerships had been unable to diagnose or repair this issue, with all repair requests being turned away. A case number was assigned by Lexus Customer Care, documenting that this defect was reported within the warranty period. No warning lamps or dashboard messages appeared at any point. The system simply never functioned correctly from the time of purchase. Although the vehicle's warranty limit is 50,000 miles, this defect existed from the manufacturing stage and was formally reported to Lexus well within the warranty period. I believe this repair should be covered regardless of the current mileage, and I respectfully request that NHTSA investigate this matter.

Flash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines the use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU initializes the flash reprogramming sequence.
