SERVICE BRAKES, ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On April 1, 2026, while pulling into a parking space at our church, I was applying the brake when the vehicle suddenly and forcefully surged forward without warning. The unintended acceleration was intense and unexpected, occurring despite continuous braking input. This resulted in the vehicle striking the building and causing significant damage to both the vehicle and the structure. This incident has occurred twice within a 10 day period, both times during low-speed parking/stopping maneuvers. There were no warning lights, alerts, no automatic emergency braking engagement, no air bag deployment, or prior indications of malfunction. I did report this to the police and they filed an Incident Report. Lexus was notified and an independent analysis engineer examined the data from the vehicle's CDR System. This report was sent to me and to Lexus.

I was not made aware of the recall on the rubber oil cooler hoses. The rubber hoses malfunctioned and all the oil leaked out on 4/13/2026. I paid to have fixed. Lexus kept the hoses. This could have ruined my engine, caused an explosion or fire. When the warning light came on I stopped driving. Lexus would not discuss the issue. I am concerned I was never made aware of this issue. I bought the vehicle in 2012 at the dealership and all service has been done there.

LANE DEPARTURE: ASSIST
When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This happened to me once, and I noticed it trying several other times.

VISIBILITY/WIPER, UNKNOWN OR OTHER
I bought a CPO lexus 2025 RX 350 in Jan 9, 2026. This car was lightly used in less than 3 months and right now it's around 7685 mileage. However, just with 3 months I purchased this car, the A/C stops cooling and the dealership said this is due to the condenser was damaged by small road stones where the small road stones can easily pass through the grille. - We have noticed that there are multiple reports of Lexus/Toyota SUVs with condensers easily punctured by normal road debris. - Dealers acknowledge it as a common pattern. - Loss of A/C can affect defogging/visibility and is risky in extremely hot weather, e.g. causing hard breathing, etc for driver and passengers in the car. This issue needs to be fixed by Lexus/Toyota.

ELECTRICAL SYSTEM, STRUCTURE:BODY, UNKNOWN OR OTHER
Vehicle was parked, engine off, and unattended. An internal electrical fire originated in the overhead/sunroof wiring area. Damage includes melted wiring harness near the sunroof, burned center console, and soot throughout the interior. The fire originated in a constant-power electrical circuit and spread downward into the cabin. There were no aftermarket modifications, no external heat sources, and no objects in the vehicle that could have caused ignition. Ambient temperature conditions were normal and insufficient to cause this damage. This represents a serious safety defect because the fire originated spontaneously within the vehicle’s electrical system and could have resulted in a full vehicle fire or injury if occupants were present. The failure appears to involve factory-installed wiring/components and is not consistent with normal wear or external factors.

2025 Lexus RX350H purchased new on 09/04/2025. The sunroof portion of the panoramic sunroof exploded, sounded like shotgun blast. Then we heard some wind noise but realized none of the windows were open/affected. I started to open the inside electronic sunscreen but noticed glass shards so I immediately closed it back up. We were greatly startled and I could have swerved/loss control of the car, thankfully I did not. Also, if the interior electronic sunscreen would have been open at the time of explosion we could have been cut from falling glass shards and would have probably lost control of the car. We were crossing the Old Tampa Bay on the Howard Frankland Bridge (I-275) heading to Tampa, FL Airport. There are no overpasses on the bridge so no falling debris was possible and we did not see any air-born road debris that impacted the roof of the car. There were no other dents etc. in the roof or car body indicating an impact. When I took the car to Lexus to get the sunroof replaced the service representative stated it was the third replacement recently. When I picked the car up a couple days later I spoke with the Service Manager about my extended warranty coverage and the lack of evidence of an impact from road debris. He stated warranty would not cover the replacement and Lexus would not cover the replacement even on a 4 month old vehicle.

LATCHES/LOCKS/LINKAGES:DOORS:LATCH
Summary of Issues: 1.On March 3, 2026, I contacted my service manager regarding my inability to open the driver’s side door. I also reported persistent rattling sounds coming from the interior panels and driver’s side door, extending toward the rear of the vehicle that leads to the gas cap door. I was forced to enter through the front passenger door. 2.On March 4, 2026, I dropped my vehicle off at Lexus service department. My service manager got into my vehicle and was unable to exit through the driver’s door. This presents a serious safety hazard. I expressed concern that the issue could be electrical in nature; however, I was advised that new door locks were needed. 3.On March 10, 2026, my vehicle was returned to me after being serviced, with the explanation that both front door locks had been replaced. I questioned why the passenger-side lock was replaced, as I had no prior issue with that door. 4.After picking up my vehicle, I traveled and left it parked at Austin Airport until 3/15/2026. Upon my return, I experienced the exact same issue-the driver’s door would not open. 5.On March 16th, 2026, I returned the vehicle to Lexus service department for further evaluation. This repeated inconvenience has been time-consuming and frustrating. As this is a luxury vehicle. 6.On March 18, 2026, I was notified that my vehicle was ready for pickup and was told the issue was related to the door bezel. Upon retrieving my vehicle, I immediately noticed that the driver’s door lock was visibly missing. I returned to the service department and documented the issue with photographs. I was then informed that the driver’s door panel would need to be replaced. Later that same evening, while attempting to refuel my vehicle, I encountered difficulty opening the fuel door. I again heard the same rattling and popping sound extending toward the gas tank. At this point, I am concerned for my safety and do not feel comfortable operating this vehicle.

SERVICE BRAKES, POWER TRAIN, ELECTRICAL SYSTEM
I purchased this vehicle on January 5, 2026, from a family-owned dealership in Broken Arrow, OK. The vehicle was purchased “as-is” with a guarantee of sale and a Carfax report. After purchasing the vehicle, I drove it home and it remained parked until January 8, 2026. On Thursday, January 8, 2026, the vehicle experienced an unexpected engine stall while I was driving. At the same time, the slip indicator light and traction control appeared to engage. I contacted the dealership immediately to report the issue, and the vehicle was towed back to JT Wholesale Auto Sales on Friday, January 9, 2026. On Tuesday, January 13, 2026, I was informed by the dealership that the vehicle had undergone a complete inspection and that no mechanical issues were found. Relying on this representation, I retrieved the vehicle and drove it home. However, after retrieving the vehicle, I continued to have concerns regarding its condition. On Thursday, January 15, 2026, I took the vehicle to Stellar Auto Service located at 2209 N. Yellowood Ave., Broken Arrow, OK 74012 for an independent inspection. Stellar Auto Service specializes in Lexus and Toyota vehicles. During their inspection, they identified the following issues: • Engine timing chain cover leak • Worn drive belt Stellar Auto Service was informed of the slip indicator light activation and the engine stalling that I had experienced. However, at the time of their inspection, they were unable to identify or reproduce any issues related to the slip indicator light or the stalling concern that I reported. On Sunday, February 15, 2026, the slip indicator light illuminated again, and the vehicle stalled while in operation. I was forced to safely pull off the roadway. I turned the car off, waited, restarted the vehicle, and drove home. The same issue occurred again on Sunday, March 8 and 15th, 2026. While driving, the slip indicator light illuminated and the vehicle stalled. I pulled off the road turned the vehicle off, restarted it.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
On November 11, 2025, while reversing inside a garage, the rearview camera image— which had initially displayed correctly on the vehicle’s screen—suddenly froze while the vehicle remained in reverse mode. At the same time, the Pre-Collision System (PCS) failed to engage the brakes while the vehicle was traveling at approximately 2–3 miles per hour. As a result, the vehicle struck the garage structure and sustained damage. Toyota investigated this incident (Case #XXX) but based its conclusion on the incorrect assumption that I had reported either a brake system malfunction or a complete absence of an image on the display (a dark or blank screen). Because of this, Toyota determined that it could not provide assistance regarding the resulting vehicle damage. This characterization is inaccurate. The issue was not a blank screen. The rearview camera image appeared normally and then froze while the vehicle was still in reverse. My vehicle is currently subject to Recall Campaign No. 25LA06, which addresses reliability issues involving critical safety-related electronic systems. The rear visibility system is a federally mandated safety feature under 49 CFR §571.111 (Rear Visibility Requirements). When the image freezes during active vehicle operation, the system no longer provides the required real-time visibility necessary for safe reversing. Given the existence of an active recall campaign aimed at addressing reliability issues within the vehicle's electronic safety systems, this malfunction should be considered potentially linked to a defect covered by Recall Campaign No. 25LA06. The failure of the rear-view system during vehicle operation directly contributed to the occurrence of the collision.

POWER TRAIN, ELECTRICAL SYSTEM, ENGINE
I own a 2020 Lexus RX 450h with approximately 129,803 miles. The check engine light came on and the vehicle stored diagnostic trouble code P0A2D, which indicates a failure of the drive motor/temperature sensor circuit that is integrated into the transmission/hybrid motor assembly. According to the Lexus dealer’s diagnosis, the temperature control sensor located on the transmission/hybrid drive unit has failed. Because Lexus designed this sensor as part of the transmission assembly, the dealer has stated the sensor cannot be replaced separately and that the only repair is to replace the entire transmission. Lexus is refusing to acknowledge this as a manufacturing defect and is requiring me, the consumer, to pay the full cost of a complete transmission replacement, estimated at approximately $9,040.03, solely due to the failure of this internal temperature sensor. This is a critical component used to monitor drive motor/transmission temperature. A malfunctioning sensor of this type can lead to improper system operation, possible overheating, loss of power, or unpredictable behavior of the hybrid drive system while the vehicle is in motion, which presents a safety risk to occupants and other road users. This failure occurred during normal use on public roads and not due to any accident, abuse, or modification. I am requesting that NHTSA investigate whether there is a design or manufacturing defect in the drive motor/transmission temperature sensor and its housing or circuitry on the 2020 Lexus RX 450h (and related Toyota/Lexus hybrid models) that forces owners to replace the entire transmission when this internal sensor fails. This appears to be an unreasonable safety‑related defect and an unreasonable repair burden on consumers.
