11/05/20Component: SERVICE BRAKES, HYDRAULIC,ELECTRICAL SYSTEMCrash reported

The contact owns a 2023 Lexus ES 300. The contact stated that upon coasting into a parking space, the contact tapped the brake pedal; however, the vehicle independently accelerated. In an effort to avoid hitting the building, the contact steered the vehicle to the left, away from the building; as a result, the contact drove into some hedges.

12/29/20Component: VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCECrash reported

I ran my car’s left front corner into a concrete pillar at about 5 MPH, put it in reverse and then the car engine sounded as if it was accelerating and it moved backward at a rapid pace. I put my foot on the brake, no response, then put gear shifter into drive, no response, put shifter in neutral, no response, then rear left corner of my vehicle rammed into a concrete pillar/metal window frame. I then turned the vehicle off, restarted and drove away. I did not put my foot on accelerator to cause the rapid engine acceleration.

02/17/20Component: ELECTRICAL SYSTEM

11/10/20Component: LANE DEPARTURE

While driving on the highway, whenever you approach an exit or an intersecting part of a highway, the lane keep assist will jerk hard towards that exit or towards the direction of the nonexistent line on the right or left side of the lane. Weather that line of that lane has faded out or is part of a type of highway intersection. Since the car drifts in between lines of that lane (while in LANE KEEP ASSIST LKA), it is hard to tell initially what the car is trying to do. Then it pulls hard to the right or the left, depending on where that line has disappeared. While there’s always at least one f

03/28/20Component: SERVICE BRAKES

The ES model and LS, the brakes squeak while ONLY going in reverse at a slow speed. I asked the mechanic at the Lexus dealership and they responded that this was common with the newer models. This is a manufacturer defect. Very embarrassing while backing up.

05/31/20Component: UNKNOWN OR OTHER
