What 2007 Chevrolet W4500 owners say
Most recent owner complaints, unedited.
Tl*the contact owns a 2007 chevrolet w4500. While driving 45 MPH, the vehicle hydroplaned. The passenger side of the vehicle crashed into the wall and both the front and rear of the passenger side were damaged. The air bags failed to deploy. The road conditions were wet at the time. The vehicle was driven from the scene and has not been inspected. The current and failure mileages were 9,000.
The fuel filter on my 2006 chevy c-4500 has been a serious safety problem since the first day I brought the truck home. The dealership continues to replace the filter. Nevertheless, while driving down the highway without any warning, other than the check engine light coming on, the truck will go from 70 MPH to 5 MPH in seconds. On numerous occassions I have come very close to causing an accident. The dealership states that the restriction in the fuel filter is 4 times greater than normal, but provides no explanation as to why this is occuring. Since I have no way of knowing when this will occur, operating the truck with this defect places my life and the lives and property of others in serious danger. I have written letters to the dealership and to gm about my safety concerns and no one has responded to my request for information or assistance. As a sole proprietor, this defective fuel filter has forced me to suspend my business operations, becuase I am not confident that the truck is safe to operate on the road.
