On certain vehicles, the bolts that attach the rear axle upper control arms may not have been tightened properly. As a result, the bolts could loosen or break. If this happens, there can be a sudden alignment change that could lead to a loss of vehicle stability.
Safety Risk
A loss of vehicle stability could increase the risk of a crash.
Corrective Actions
Porsche will notify owners by mail and advise you to take your vehicle to a dealer to replace the nuts and bolts for the rear upper control arms. The dealer will also replace any damaged components, if necessary.
