05/16/20Component: UNKNOWN OR OTHERCrash reported1 injured

Around 11 am on Sat., May 2, 2026, I was sitting in a very long line in Starbuck's drive thru when my 2025 Lexus RX hybrid suddenly and uncontrollably accelerated--like an uncontrollable bucking horse. Brakes didn't work. I couldn't stop my out of control car, and the multiple computer sensors also didn't stop the car. It was like the throttle was engaged because of a computer glitch. In an effort to avoid hitting the car in front of me, I immediately tried to swerve, but still hit the car, then jumped the exceptionally high curb and ended up in the grass below and almost into the busy road ah

09/30/20Component: AIR BAGS,VEHICLE SPEED CONTROL,SERVICE BRAKESCrash reported1 injured

The contact owns a 2025 Lexus RX 350. The contact stated that while driving into a parking space, the vehicle suddenly experienced unintended acceleration and drove forward at a high rate of speed before crashing into the brick wall of an office building. During the crash, no air bags deployed, and the brake pedal was hard when pressed and did not stop the vehicle. Also, the manufacturer's APP indicated a malfunction in the engine and engine throttle during the incident. The driver sustained injuries to the knees, arms, and hips, which required medical treatment. An incident report was filed

04/16/20Component: SERVICE BRAKES,ENGINE,FORWARD COLLISION AVOIDANCECrash reported

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 deplo

03/15/20Component: BACK OVER PREVENTIONCrash reported

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

05/28/20Component: TIRES

The passenger rear tire (235/60R19 - Michelin Primacy A/S) randomly blew out while driving at high speeds on the highway. No trauma via a pothole or other object was noted. Tire was inflated to the manufacture recommended PSI (33 PSI). No signs came up until the tire blew out. The tire just randomly decided to give out while driving.

05/09/20Component: AIR BAGS,SEAT BELTS

The car does not alert when a seat belt is not worn in the back seats. This feature is mentioned in the owner's manual, but the car fails to alert when a rear passenger does not buckle their seat belt. I have raised the complaint twice and proved to lexus service center, that car doesn't warn or alert the safety belt. It was also proven and checked by Lexus with their technician. The problem is accuring right from the time car was purchased, When check with the dealer it was designed , but their manual confirms the seat belt not worn warning light is included in the package. It put the an

04/10/20Component: UNKNOWN OR OTHER,VISIBILITY/WIPER

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 extrem

03/28/20Component: UNKNOWN OR OTHER

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
