Power Train

ODI #11575109

Incident: February 20, 2024 · Filed: March 2, 2024

My transfer case established a large fluid leak so I inspected it, the findings was a large hole in the main housing on the transfer case fluid was leaking out. The transfer case was removed and disassembled, and found that the 2 screws that hold the chain guide to the housing had backed out or fell out and let the chain guide fall down in to the gear mechanism and ground it up and broke the main case. In result was the quarter size hole in the housing of the transfer case allowing liquid to escape and damage the housing. Leaving me without a vehicle.

Fire

Incident: January 11, 2015 · Filed: January 13, 2015

MY HEATING AND AC BLOWER MOTOR STOPPED WORKING ON A VEHICLE THAT HAS LESS THAN 31K MILES ON IT. THE ESTIMATED REPAIR COSTS ARE 500$, NOT INCLUDING THE TOW, BEING THAT IT IS THE MIDDLE OF WINTER AND THE CLOSEST DEALERSHIP IS 20 MILES AWAY. ADDITIONALLY, THE TIME OFF OF WORK AND EBING WITHOUT A CAR FOR A WEEK. I HAVE HEAVILY RESEARCHED THIS ISSUE AND IT HAS BEEN REPORTED THOUSANDS OF TIMES AND IS A WELL KNOWN ISSUE AND GM HAS NOT ISSUED A RECALL. THE PROBLEM IS THAT A FAULTY ELECTRICAL SHORT CAUSES A WIRING HARNESS TO MELT, (SMOKING) WITH A BURNING SMELL AND BLACK RESIDUE. THIS IS A MAJOR FIRE HAZARD AND THE RECOMMENDED FIX FROM THE DEALERSHIP ONLY REPLACES THE HARNESS, BUY DOES NOT ADDRESS THE CORE ISSUE CAUSING THE FIRE HAZARD. THIS IS LIKE REPLACING BURNT DRYWALL TO ADDRESS FAULTY HOUSE WIRING . *TR
