What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Vehicle was involved in a collision in which driver's/passenger's air bags did not deploy, cause unknown. Please give any further details.
While driving on the highway the read on one of the vehicle's tires separated yet the tire remained inflated. The tread separation caused some damage to the body of the vehicle. The tire manufacturer was contacted and inspected the tires. They concluded that the didn't notice anything unusual about the tires.
Requesting documents pertaining to mis shift and park to reverse safety defects in these vehicles. Vehicles shifting into park position but vehicle still moves forward or reverse unexpectedly or without warning.
The manufacturer also states that the problem of brakes overheating is pervasive, but says it is not a design flaw. I have asked the manufacturer to either provide a fix, or extend the warranty for the life of the vehicle, but the manufacturer has refused.
On two occasions vehicle experienced sudden acceleration which resulted in loss of control causing vehicle to collide into garage. Yh
Having to replace the brakes on this car. Replaced at 28,000 miles now again at 34,000 miles. Do not ride brakes when driving. Service manager at dealer said this is a problem with this truck because of it's weight. Yet, dealer is charging me for repairs !!!
