Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“When driving, there is a constant and very strong vibration throughout the entirety of the truck. This makes it difficult to steer and drive in a safe manner. I've replaced any parts that might be associated with this malfunction with brand new parts at the advice of professional mechanics (cost over $30,000) and it was to no avail. The truck is still malfunctioning and I have been left unable to work or barely working for 14 months. The vibration has caused many health concerns, like headaches, nausea, and stomach ulcers. …”
