as I attempted to turn left in the parking lot of a strip mall with several restaurants, my engine suddenly revved and accelerated and despite pumping the brakes several times I could not slow it down or stop it. As a result I slammed into a concrete berm, kept going and crashed through the glass doors of a coffee shop/restaurant, continued on and the car did not stop until it hit a metal counter. Fortunately I was not hurt, nor did I kill anyone, although I was told two workers went to the hospital with bruises and lacerations on their legs. Since I was unable to stop the car, not only was my life at risk, but anyone who crossed my path or who was in the coffee shop could have been crushed. The police came, made a report and had my car towed to their impound lot. The problem has not been reproduced or confirmed by a dealer or independent service center as of yet. . My insurer will have the car towed to a preferred repairer and they will inspect the car to determine whether it's repairable. I have asked them to check what made the car suddenly accelerate. I was informed at the police lot that they expect the car will be towed and inspected on Monday, 7/18/22. The accident occurred on 7/14/22. The vehicle has not yet been inspected by the manufacturer, police, insurance representative or others. There were no warning lamps, messages or other symptoms of the problem prior to the failure. The vehicle is available for inspection upon request.
