What 2018 Audi A4 Allroad owners say
Electrical system
Involved in a three car rear-end accident. I was the very front car (car 1, white 2018 Audi A4) which was completely stopped that took the least force of the impact. Car 2 (Tesla medel s) was also stopped but took brunt of force from at fault car 3 (Dodge SUV) who came barreling in. My car took minor damage to the rear yet my 2018 Audi A4's collision protocols disabled my car and left it completely undriveable. The seat belts also pulled back and locked up leaving me unable to rebuckle my seat belt after the accident. This meant I was stuck in the middle of a busy highway unable to move to the shoulder with no protection besides the shell of the vehicle. …
