The carbon fiber roof of my 2016 BMW i3 REx is really starting to bubble and wrinkle. After taking it to two shops any mitigation would cost hundreds of dollars to address. The roof is starting to peel and am worried about water getting to the car. BMW should have engineered these roofs differently. They should be responsible to cost associated with fixing them.

I was pulling into my driveway in the morning at around 9:15 am preparing to park BMW I3 electric vehicle in to the garage. I had my foot on the brake and was waiting for the garage door to open. The vehicle was stationary but notice that brake was not functioning properly, meaning there was no feeling of vehicle was in a lock position due to the brake being pressured on the wheel. Then all of sudden, the vehicle went accelerating or "sudden unintended acceleration". the vehicle went through the garage door that was only half way up and was still going up. Then, the vehicle continued its unintended acceleration crash impact to the refrigerator that was against the back side of the garage wall. The impact of the vehicle to the refrigerator and the wall took out entire back side of the garage wall of about 20 feet wide X 8 feet tall wall and threw off refrigerator 50ft to the ground level. The vehicle stop from the impact and almost half of its body length was cantilevering off the edge of the back side of wall. My house is built on about 35 degree slope and the vehicle was cantilevered about 45 feet from the ground. The police and fire department was called and they were able to safely bring the vehicle off the edge and the vehicle was tow to the local BMW dealer where I had it leased. I made a requested to the local dealer manager in person not to temper with the vehicle until all parties that may have interest in this case have made their input on it. I've called in to the BMW North America and informed this incident. I've reported this incident to my home and auto insurance company. Please review this case because the condition that I am reporting "sudden unintended acceleration" did happen and it was super fast! the total distance the vehicle traveled from the station position to impact/stop was about 50 feet maximum, standard garage length plus about 10 feet.
