traveling on S Sterling Street in Morganton, NC on the morning of July 12, 2023. We were going speed limit20 mph on a one way street, then car made rumbling sound and accelerated on its own at approximately 60-70 mph. I put on brakes,but car did not slow down...weaved thru traffic to avoid hitting anyone..could not get car to slow down and unfortunately hit a car in front of us. All persons were taken to hospital..myself, my wife and person in the other car that was impacted. All persons suffered broken bones. Both cars were totaled. Since accident have read up on this type vehicle accelerating on its own. We were lucky no one was killed. This needs to be looked into before it takes a life.
