I have a 2020 GLE 350 and today, I was turning into a parking on my right. I stopped my car, switched the cameras, so I could see the parking slot on the screen. Just when I took the right turn into the slot, the car accelerated at the same angle and jumped onto the curb. I tried hard to brake, but the brake was not working. I had the presence of mind to press the Park button on the gear lever and then the car stopped. No car damage or no injury, but it was a close call. I called 911 and the Johns Creek police helped me to get the car back in the parking lot,. A police report was not filed
