Transmission & Drivetrain complaints by model year
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.
NHTSA complaint #11575109 — an unverified report by a vehicle owner.
I was driving the vehicle at a normal rate of speed and stopped at a traffic light getting ready to change. I applied the brakes and when doing so, I heard some horrible noises and felt certain that parts had fallen out of the car. I knew something was immediately seriously wrong. I put the car in park (but it was effort and a grinding noise to put it in park) and stepped out to look under the car. No parts were on the ground, but something was leaking out of the bottom of the car. I got back in and put the car in drive to move it from the roadway knowing I was going to need assistance to tow it somewhere. It grinded trying to put it in any gear and only "revved" the engine when I tried to apply gas to drive it. There was absolutely no warning. The tow driver immediately noticed the drive shaft was disconnected and that was the leaking and thus going nowhere. My mechanic said that both leaf springs snapped off and that caused the drive shaft to sever, hitting the gas tank (or strap) and some other things. My concern is that there is a recall on leaf springs for every year Hummer H3 except mine as well as 1995-2015 Chevrolet, GMC, and Hummer leaf springs. I'm having a very difficult time with how both of mine snapped with no warning tearing all of these components out and it is not involved in the recall. It is the same parts on all of these. Also, my vehicle has spent the majority of its life garaged, never driven in the snow or rain, as I have babied this car. I have a car wash membership too and constantly keep this car meticulous. Hummer said that enough people need to complain, but I would not even have thought to complain had BOTH not snapped off simultaneously finding the recall for all other years while researching the cost. Had only 1 broke, I wouldn't have given it any thought. And Hummer said that they wouldn't even talk to me unless my car was at a GM dealership. This should be included in the recall. This is not pure coincidence. They need to fix it.
