On Saturday morning my truck would not start. I went to jump it, and with no keys in the ignition and not jumped yet the windshield wipers and interior light went on. This went on for over an hour. I replaced basically a new battery. The radio did not work and dash lights did not either. On Tuesday, April 17 after I picked up my son from school, the car started to make a loud scrunch noise and started to stall off and on. When I pulled into my drive way and shut off the engine I smelled something burning. I went to open the door and it would not open. I tried to open the windows and they would not go down. It was smelling really bad like something was on fire. About 25 seconds later, with no key in the ignition the interior lights went on. I put the key in the ignition but did not start it and tried the windows again and my drivers side went down and I got my son out through the window. It had to be towed to the dealership. They said it was my alternator which is getting fixed. Reading all the complaints I agree, why has this not been recalled. It's around 50k miles and the electrical goes. Luckily me and my son got out.
