“I was pulling into a parking spot in the upper parking lot at work. I stepped on the brake pedal so that I could stop and park but the pedal was hard and had no give. The car continued to roll forward over a curb and partly down a small set of stairs that go from the upper parking lot to the lower parking lot. The car stopped when it hit a metal railing and I shifted the car into park.”

“Happened to me two times in past three weeks, where I am coming to a stop, or hardly moving, and car suddenly accelerates. Had my foot on the brake and the car was still trying to accelerate. Yesterday, 4/24/21 it took all my strength on the brake to keep the car from pulling into oncoming traffic. I have been driving for 39 years and have owned many cars, and something like this never happened to me. I will be bring the car dealership tomorrow, the car has only 10k miles on it as we don't do a lot of driving with it as we owe two cars. …”

“I wanted to say it happened to us while we were driving back from a daytrip on saturday. We had our kids in the car and my husband was driving. All of a sudden the scbs light came on and the car just stopped giving gas. The car behind us couldn't tell we were slowing down because there was no brake light. We were almost rear ended. The car behind us couldn't stop in enough time so they just swerved onto the other side of us. We had to pull the car over and it was almost nighttime. My husband ended up pushing the car to get it off the road and to a safe place. It would only go 2 miles per hour. …”
