I was pulling into a parking space. Hit the brake. Instead of stopping, the car accelerated, jumping a curb and barreling across into another business drive. It hit a sign and a stone garbage can, which caused the car to recognize a collision and automatically go into park which caused it to stop. If it hadnât been for the stone garbage can, it would have gone through the store window where people were sitting. Luckily at that moment there wasnt a car parked in the space or something coming down the road. Because I didnât understand what was happening , so I looked at my foot to see if I had pushed down on the gas instead of the brake. My foot was firmly on the brake. I talked to the local Honda dealership. They had never seen that issue before. They said they could do the diagnostic which I would have to pay for, but couldnât promise it would show what happened. I also called Honda customer service. They started a claim, but also would do nothing unless diagnostics showed the problem and also said it may not. I was very fortunate that i didnât kill or seriously harm someone. I am now scared to drive the vehicle. If I had not looked at my foot to see where it was placed, I would say possibly driver error; but I know it wasnât. My foot was on the brake
