general problems of the 2008 Chrysler Aspen

On may 9th 2019 the vehicles computer was giving strange alerts about tire pressure changing among all 4 tires. Also change oil alert on & off. Low gas alert on & off. When I arrived at work around 9 am & I parked the vehicle, brought my personal things into the office. I decided to use our compressed air to check all 4 wheels tire pressure. I put the car in reverse to back out of the parking space with my right foot on the brake pedal. As I was backing up the rpm's increased suddenly sending me speeding in reverse towards my work building. I looked at my foot to make sure it was on the brake & it was. I never touched the accelerator. The vehicle's speed increased in 3 seconds to over 40 mph. I backed through the corner of my building, across railroad tracks & into the neighboring building. The corner support beam of my building went through my sunroof missing my head by inches. I turned the engine off. Miraculously no one was seriously injured. The vehicle was totaled & it caused extreme damage to both buildings. I contacted an attorney but since there was no serious injury they didn't want to get involved. They said it wasn't worth it to them. I tried to reach Chrysler but never got a response. I was recently made aware of this website to file this complaint. I have a video from my work security camera it is not one of the type of files this website accepts.
