On certain vehicles, a minute crack may develop on the surface of the steering lock bar, which is a component of the steering interlock system. Such a crack may expand over a period of repeated lock and unlock operations, and eventually the lock bar could break. If this occurs, the interlock system may become difficult to unlock when stationary. If the vehicle is steered to the right while in motion with sufficient lateral acceleration, a broken and loose lock bar may move toward the steering shaft. If the engagement hole in the shaft happens to line up at the specific time the broken lock bar has moved, this could cause the steering wheel lock bar to engage, resulting in a sudden loss of steering control. Correction: Dealers will replace the steering interlock device.
On certain vehicles, improper heat treatment during assembly could result in inadequate strength in certain areas of the rear axle shafts. After extended use of the vehicle, the rear axle shafts may fail or break. This could result in rear wheel separation and a possible crash without prior warning. Correction: Rear axle hub will be inspected and replaced if necessary.
