I had an '06 Charger SRT8. Great car, I loved that 6.1. Anyway I don't think it's brakes either. Maybe alarm as mentioned. I can only imagine what sensors may have been damaged too though, causing no start. Crank position sensor maybe. That is at right rear of block though but who knows with the moving around of the vehicle. Can you even access shifter and move it to different positions to see if it's misaligned?
