ELECTRICAL SYSTEM
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.

I have tried to get Stevenson Lexus in Lakewood Colorado to replace the head rests , they have not ever had the parts to complete the recall. I have been waiting for over a year. I called Lexus headquarters in Texas and was told that there is a remedy but Stevenson Lexus has never offered that to me.

POWER TRAIN
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."

POWER TRAIN
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.

VISIBILITY/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 — 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.

First incident. 71 mph, 101 degrees out traveling along a straight highway, I hit the seat cooler button and when I did, my car lost power. I could not get any response when I hit the accelerator. I tried several times. This was on XXX with around 500 miles on the car in the odometer. I had it less than a week. Second incident on XXX 25 mph, 105 degrees outside with 1300 miles in the odometer, I again, lost power and was unable to accelerate. I was on a windy road that required the use of both hands on the wheel. With this incident I lost the AC in the cabin. I had to pull over both times and turn off my vehicle and turn back on. There were no lights, or warnings or beeps letting me know that my car was going to lose or lost power. I took the vehicle to Crown Lexus in Ontario, they had it for 7 days and they could not find anything wrong with it. When they ran a diagnostic on it, there were no codes other than they said I put the car in neutral while driving. Which did not happen. My husband was with me both times. I then had the car towed to Lexus of [XXX] and we went for a test drive, as they wanted to see how I drive to rule out human error and to see if the car would have another incident. It did not. They kept it overnight and could not find anything. The first dealer drove it about 70 miles and the second around 10 miles to diagnose. The green ready light was on the dash. As to what component failed? I am not sure other than I could not accelerate and the ac went out. My safety and my husbands, along with other drivers, was put at risk due to the fact my car was traveling at a high rate of speed and it just lost power. I could have been rear ended. I could have been on a road without a shoulder to move over to. This could have been a major catastrophe. The dealer(s) have been unable to reproduce the incidents. There has been no inspection other than at the dealer, and during both incidents, no warning lights, or beeps were seen or heard INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

POWER TRAIN, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
The vehicle has exhibited intermittent drivability and safety-related concerns after a prior collision repair. The concerns include delayed acceleration/engagement, abnormal jerking or stopping behavior, and elevated RPM behavior during real-world driving. The most recent documented event occurred on July 27, 2026, while the vehicle was in Drive at approximately 50 mph with cruise/driver-assist indicators illuminated. The tachometer appeared near the 4,000 RPM range. The event was captured by video/screenshot and the vehicle is available for inspection upon request. The issue creates a safety concern because delayed acceleration, unexpected jerking/stopping, or abnormal RPM behavior could affect the driver’s ability to safely merge, maintain speed, respond to traffic, or control the vehicle during highway or road driving. The problem has been intermittent and has not always produced an active warning lamp. A Lexus dealer inspected/scanned the vehicle on May 21, 2026 and discussed Eco Mode/Normal Drive Mode, but the symptoms continued afterward. The vehicle has a documented post-repair history involving transmission cooler replacement, transmission-fluid concerns, and prior transmission/powertrain/electronic-control diagnostic code history. Lexus Brand Engagement has also been notified under an active case, but there is currently no clear authorized Lexus repair path. The exact failed component is UNKNOWN. Based on the symptoms and repair history, the concern may involve the power train, speed control, electrical/electronic control system, or related driver-assistance systems.

While on a long road trip on a hot day, on the interstate, the car suddenly lost speed and would not accelerate. It was like the car had shifted into neutral. I was coasting on the interstate, steadily slowing, and was forced to pull over to the shoulder. I turned the car off and waited a couple of minutes then turned the car back on. No error messages were displaying at that time. About 5-10 minutes later, I pulled over for a planned stop. My husband assumed driving responsibilities when we got back into the car. Upon trying to get back on the interstate, the car would not accelerate, and multiple errors error messages appeared, including: ""System Malfunction/Visit Your Dealer," "Check Engine/Visit Your Dealer," "Drive-Start Control Malfunction/Visit Your Dealer," "Secondary Collision Brake System Malfunction/Visit Your Dealer," and "Traction Control Turned Off." He pulled into a nearby parking lot where we had to have the car towed to the dealership. It felt like the car was in neutral when this happened both times.

On July 21st, 2026 while stopped at a red light and upon turning green stepped on the accelerator to transition from stop to start, the vehicle suffered a sudden, catastrophic loss of motive power. The engine failed to respond to accelerator input, leaving the vehicle stranded in active traffic. This created an immediate rear-end collision hazard in a busy intersection. I was forced to coast the vehicle out of traffic to the side of the road, cycle the ignition off, and reset and temporarily regain powertrain functionality. Also on July 25th, 2026 I lost the power to accelerate on the highway when I was cutoff. I put the car in neutral and then back in drive to get power back to accelerate. These are the most recent, But I have had 2 transmission replacements. At separate times and then a re flashing to upgrade computer information another time. All within a 7 month period. This is a known issue by Toyota Motor Corp and has been circulated by the company under TSB-L-SB-0059-23.

My wife was driving the subject car She intended to come off the road to give a way to on coming car. She got in naghbour's drive way and intended move 10 feet. When she tried to put more gas to move the car was hyper accepting drove 50 feets away and hit naghbour's ion gate and stopped. When she back off it did again and hit street lamp. It did two more time. Ended up damaging 4 corners of the car and all the material that the car hit. I could not understand that she hit the 4 corner of the car. That is why I suspected engine problem. When I tried the same movement nàghbour came out and worry that the car will do the same thing. While I was talking to him. He told me he has security camera and he noticed excess unning of the engine. He sent me the clip I couldn't see the car but certainly I could hear the engine. The end of the report.

The panoramic sunroof shattered while the car was parked and there were no occupants. Lexus USA refuses to acknowledge this defect and the dealership insists there was an impact that caused this damage. There was no impact. I have asked the dealer for a written report of their determination of the point of impact and to return all broken glass to me. I do not know yet if they will comply with either request. As the car was parked, there were no immediate safety concerns, but due to the risk of additional glass falling onto the driver and passenger seats, the car was not in a drivable condition. Had this happened while driving, the sound of the shattering and the glass falling may well have resulted in a reaction from me causing immediate danger to myself and others on the road. UNKNOWN if problem has been reproduced, but this is not an isolated incident. Vehicle component had not been inspected by manufacturer, police , insurance reps or others. There was no warning or other symptoms of this problem.

My 2023 Lexus RX350 with 67,000 miles displayed a check engine light along with a Drive-Start Control Malfunction warning. The vehicle was brought to a Lexus dealership where it was diagnosed with fault code P25B372 — Turbocharger Wastegate A Actuator Stuck Open. The dealership confirmed the wastegate actuator has failed and requires replacement. The part is currently on backorder with over 800 units backordered nationally, indicating this is a systemic issue affecting multiple vehicles. Toyota has issued Technical Service Bulletin T-SB-0084-23 covering this exact fault code on the same 2.4L turbocharged engine used in the 2023 Lexus RX350. The bulletin states the repair is covered under the Federal Emission Warranty for 96 months or 80,000 miles. However, the Lexus dealership has declined warranty coverage citing the absence of a Lexus-specific bulletin, despite the identical engine and fault code. The failure puts safety at risk as the Drive-Start Control Malfunction warning indicates loss of traction and stability control systems. The problem has been confirmed by the Lexus dealership. Warning lamps appeared on the dashboard prior to the visit. The vehicle is available for inspection upon request.
