Hopefully someone here can help. I have been to 2 dealers and so far no luck. I have a 17 suburban with the lux package so it has the push button start. In the past 4 months randomly when I go to start the car the needles all swipe but doesn't start. After trying mult times it finally starts. I tried the keys in the cup holders and it doesn't work. Also tried changing keys and batteries. The last dealer said they tweaked the break peddle the last time but still doesn't work. I have video If anyone wants. Finally it always says service 4wd. Even though after it starts the code never pops up
