On July 15, 2022, my 2022 RX450hL drove itself across approximately 150 feet of rugged desert terrain and ended upside down in my neighbor's driveway. No one was in the car and no one was in the driveway where it landed. I had parked the car on the side of my house, after several seconds the car took off across the desert to self-destruct. I contacted Lexus, someone from their legal dept. contacted me and they sent a representative to collect the "black box." After that Lexus refused to take my calls or provide any information to me about the "black box." I had taken possession of the

The vehicle hesitates with apparent gear dragging and audible whining or grinding noises. The condition worsens when driving uphill and includes occasional sudden increases to high RPMs during normal acceleration. A slight burning odor is sometimes present after driving, along with lower-than-expected fuel economy in city and highway driving. The transmission exhibits harsh shifting, hesitation, and loss of smooth acceleration, negatively affecting drivability and raising safety concerns.
