Dealership stuck a bolt into the firewall that caused heavy cracking and metalic noises when turning wheel and going over bumps after repair attempts from the dealership to fix the noise over a lemon case i opened with toyota eventually they called all the problems fixed i could still hear the same noises and kept the bolt stuck while my lemon case got denied . So i had no idea of this bolt stuck in my firewall until yasterday when i took it to an outside mechanic .basically the screw in a bolt too much into the firewall it got stuck there and cant be unscrewed and already caused a damade that can be heard. What actions should i take at this point?
