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
