Specific parts of the rear suspension may not have been torqued properly when installing the rear coil springs. As a result, the rear suspension arms may detach, increasing risk of a crash.

Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle. These models are being recalled because the incorrect vehicle weight rating is shown on the information label. This could result in vehicle and tire overloading, increasing the risk of tire failure.
