NHTSA Complaint #11527193 — 2021 VOLVO XC60

My car continued to move even with the brake pedal pressed, and collision avoidance systems did not turn on. This is very unsafe - a car that doesn’t respond when the driver brakes puts everyone else on the road in danger. The first time this happened was on Sep. 6, 2022. I was driving on the highway when the car in front of me stopped abruptly. I started to brake. The distance between our cars was large enough that I should have been able to stop safely, but my car continued to move. I was unable to stop the vehicle and crashed into the car in front of me. At the time, I thought it was my fault. Although there was damage to my car, luckily no one was injured. (This was resolved, and my car was repaired, with help from Shelter Insurance.) On June 13, 2023, I was pulling up to a red light behind another vehicle. I stepped on the brakes and my car jolted to a stop (I had to push the pedal down very hard to get my car to start slowing down). Then my car began to move again, even though I had not released the brake pedal. It was moving at about 1-2 mph. My car got so close to the car in front of us that the parking sensors began to beep. We would have run into the stationary vehicle if I hadn’t put my car in Neutral. When the light switched to green I put my car in Drive again. At the next intersection the brakes were back to normal, and my car was driving as before. I had my car towed to the local Volvo dealership. After an inspection, I was told they hadn’t found anything wrong. I left my car at the dealership for further investigation, and was given a loaner. I don’t know if there is a connection, but both times this happened, I had been driving on the highway at high speeds (70 mph) for a few hours before trying to brake.
