My 2015 GMC Sierra 1500 4x4 tried to start when I was not in it!
Truck is 22months old w/ 52000miles. I was not in the truck, Keys were in my
pocket and ONSTAR app not activated. I got in and hit the brake
pedal(nothing) put keys in ignition and it wouldn’t start, only was attempting
to start....now smoke comes from under hood. I rushed under hood to remove
starter relay....(it was smoking and melted), it WOULD NOT stop engaging
starter. Now starter is smoking , I rushed to get tools to remove the battery
cable( this happens over 4 to 5 minutes) , throwing snow on fuse box and
starter, finally get positive cable off.........WOW what a mess. $2000 damage.
Truck towed to dealer, no explanation other than RELAY STUCK! Dealer calls
General Motors for technical and product claim assistance.
GENERAL MOTORS CALLED AFTER 9 days and DENIED ASSISTANCE WITH
NO EXPLANATION OF CAUSE. EVEN THE GM DEALER WAS SUPRISED,
I HAVE VIDEO OF SOME OF THE 4-5 minute ordeal.
