Car power shut off while driving on the highway to church and almost got in an accident. Pulled to the side and smelled smoke. Lifted the back seat and opened the fuse box and looked. Lifted the fuel pump fuse and it was burnt. Me and my family got stuck on the side of the highway instead of church and spending time on a holiday.

Due to my injuries I was in intensive care and the hospital for nine days and spent 20 days in a rehabilitation facility. I am home now,...

still in pain and moving around with the help of a walker. I have owned cadillacs for the last 30 years. I will never drive another one. If this happened once, what is to say it won't happen again.
