Defect Involved, Dealer Action, Campaign & Material & Owner Notification Information

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety may exist in some 1988 Buick Regal model vehicles. These vehicles may have been produced with a condition that could allow the lower control arm to ball joint attachment to become loose. Additionally, a small number of these vehicles could have tie rod ball stud nuts that were rot properly torqued and could loosen. Continued operation of a vehicle with a loose lower control arm to ball joint attachment or a loose tie rod ball stud nut could eventually result in a separation of that joint. Jn either case, loss of steering control could result and a vehicle crash without prior warning could occur.

DEALER ACTION

To prevent this condition from occurring, both lower control arms will be replaced and the tie rod ball stud nut torque will be checked or all involved vehicles.
