I pulled into a parking spot and noticed nothing out of the ordinary with my vehicle. When I was stepping away from my car and pushed the lock button there was no clicking sound. I continued into the building and returned to my car a few minutes later and it would not start. All of the lights would come on, but the brake locked up and the car would not start. I attempted to charge the battery which did not work. I unhooked the battery cables for a period of time to reset the lock system and possibly unlock the starting system, which did not work either. It has only been two weeks since I took this vehicle into the dealership to have the computer system updated due to engine failure issues in other vehicles. I purchased this vehicle less than a year ago and it does not show from what I can tell a recall. However I was instructed by the dealership to have the car towed into them so they can check to see if it is engine failure or a number of recall issues that I have not been aware of.
