“I put in 4high lock for snow. I later put truck in 4 high. It feels as if it's stuck in 4high lick. I took it to repair shops and was told it's the 'plastic fork' on the transfer case and this is a faulty problem. The for was later changed to a metal kne because of this problem. It should have been metal in the first place. This is an expensive cost and I am in great hopes that the manufacturers will honor this.”

“Was driving 40 MPH on a 2-lane northbound highway. Weather conditions were clear and sunny. A car pulled onto the highway and instead of pulling into the right lane, it pulled into my left lane. I had to press the brakes a harder than normal. At that point both rear leaf springs failed and blew apart, damaging the drive shaft and pulling the drive shaft from the transfer case. The rear axle was pushed to the very back of the vehicle, making it un-drivable. There was also some other underside damage, such as the emergency parking brake line, seals, gaskets, etc. …”

“Purchased a 2006 Hummer H3 from the seller in this complaint. I paid exactly $23,250 all cash for this vehicle. He actually drove the vehicle to new jersey from mass. To my residence. The vehicle appeared to be in excellent condition, as it only had 14k miles when I bought it only 3-month's ago. One would hardly think of hidden issues at that mileage. In any event, I have had repairs to the rear and front differential, as it had a leak and the front end was out of alignment. The most disturbing thing was this seller lied to me and misrepresented the true or actual condition of the vehicle. …”
