“Vehicle was in 4 wheel drive, when the whole truck shuttered, I lost the drive capabilities of the truck then stopped and looked underneath vehicle to find fluid coming out of the transfer case. In my case this happened on a residential street, if it would have happened on highway it could have resulted in a very bad accident. Please contact me on a possible recall for the transfer case. Updated 12/01/2014”

I've also had my air conditioning go out twice and is nearing failure again. The front hub assembly has also gone out twice on this truck. Once the repair was made under warranty.”

It was everything I could do to make the turn and pull to the right. At the time I was pulling my 2009 bighorn fifth wheel trailer. It was a scary time. I finally stopped, lucky there was no cars parked on the right near the curb. I put the transmission in neutral and restarted the engine. Then we continued the trip home to winters, ca. …”
