Power Train · reported Mar 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.

The vehicle sometimes will not start due to a problem with the security sensor in the ignition switch. This is when starting up the vehicle and will only periodically occur. The security system light comes on and you have to wait 10 minutes to start the vehicle, then it will start. It has happened in the summer and now the winter.

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…

Electrical System · at 80,300 miles · reported Jun 29, 2013

I was driving home and the fan on the A/C stopped working. Shortly afterward I detected a burning odor. I ended up replacing the resistor and wiring harness for the A/C blower motor. The resistor was burnt and the harness wire was slightly melted. I AM concerned about the potential for a fire if this happens again.
