NHTSA Complaint #11197089 — 2015 GMC CANYON

WHILE DRIVING WITH VEHICLE IN FOUR WHEEL AUTO THE TRANSFER CASE ENGAGED IN TO 4 WHEEL HIGH AND WOULD NOT DISENGAGE. THIS WOULD BE MORE OF GREAT SAFETY CONCERN IN THE EVENT THAT A DRIVER IS NOT ABLE TO PULL OVER AND STOP. THE VEHICLE WOULD NOT DISENGAGE THE FOUR WHEEL DRIVE AND REQUIRED TO BE TOWED TO DEALERSHIP. THE WORK PERFORMED TO CORRECT THIS ISSUE INDICATED THERE WAS AN EXCESSIVE AMOUNT OF CORROSION IN THE THE CONNECTORS RELATED TO THE "RANGE SELECTOR" AND OTHER RELATED COMPONENTS. THIS APPEARED TO FIX THE ISSUE, HOWEVER THE ISSUE HAS RESURFACED OVER TIME AND AGAIN SEEMS RELATED TO CORROSION. IN MORE RECENT OCCURRENCES THE VEHICLE ENGAGED INTO FOUR WHEEL DRIVE WHILE DRIVING AND IT WAS NOT SET IN FOUR WHEEL AUTO. THIS IS EXTREMELY CONCERING AS I STOPED USING FOUR WHEEL AUTO BECAUSE OF THIS PAST EVENT. AGAIN THIS ENGAGEMENT OF THE FOUR WHEEL DRIVE WHEN THE DRIVER IS NOT ABLE TO RESPOND ACCORDINGLY COULD LEAD TO INJURY.
