Pontiac Bonneville: Suspension
Affects Pontiac Bonneville · 1999 — about 32 vehicles.
The hazard
On certain vehicles equipped with chrome plated aluminum wheels, the wheels may have a mounting surface that was not machined correctly. This would cause the wheel studs to break and the tire and wheel assembly to separate from the vehicle. If this were to occur while the vehicle was in motion, a vehicle crash could result without prior warning. Correction: Dealers will inspect wheels and replace all wheels with date codes indicating that they may not have been machined correctly. The wheel mounting studs at any location where a suspect wheel was installed will also be replaced.
