2026 Lexus Rx

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)
