2010 Chevrolet Equinox electrical system problems

Tl* the contact owns a 2010 chevrolet equinox. The contact stated that the vehicle failed to start without warning. The contact purchased an electrical box from the dealer to repair the engine failure; however, the box did not assist with the failure. The contact stated that the failure occurred again four days later without warning. Since owning the vehicle, the contact has had the engine, fuel pump, electric line, doors, and windshield wipers replaced.

I have owned this auto, which I purchased from a chev. Dealer in atmore, al dec 2011; first sign of trouble was notice to replace electronic board, and battery which was run down & alleged due to fail., replaced under bank service warranty, plus $110. From that point onthe car would start unattended, and parked, locked with alarm on. Attempts to correct meant fighting to get lock to stay open with key, and inserting same into ignition.
