“On Friday, September 15, 2023 3:00PM, I had a “horrible” experience with my Lexus this weekend and sudden unintended acceleration. I was sitting at a red light, with my foot on the brake. Without warning the engine began to rev, the tires squealed and the car lurched forward. I through the car into park & turned of the car as quickly as I could react and “thank god” no one was injured and there was no accident. I was in the car with my wife and she reminded me she had a similar experience a month ago. I didn’t know what to think when she told me. …”
