On Friday 4/26/24 at about 8 PM, I pulled vehicle into garage and suddenly was aware that vehicle was crashing into shelving against the garage wall in front of its usual stopping place. I recall application of brakes and believe that I put into reverse in order to stop progression/acceleration. After it stopped, I was able to get out of the vehicle and describe the incident to my husband who came out from the house, having heard the crash. The hood and front parts of the car were damaged and it is currently in the collision shop. The shelving unit was destroyed. I am concerned that an unintended acceleration took place and do not know the mechanism.
