# Customer Satisfaction 99050-Starter Motor Failures-Inspect/Replace Starter Motor

Subject: | 99050 -- Starter Motor Failures -- Inspect/Replace Starter Motor

Models: | Certain 1998 and 1999 Buick Park Avenue Ultra, Riviera, Regal Model Vehicles

| Certain 1998 and 1999 Pontiac Bonneville, Grand Prix Model Vehicles

| Certain 1998 and 1999 Oldsmobile Eighty Eight LSS Model Vehicles

| Equipped with 3.8L Supercharged Engine (RPO L67-VIN Code 1)

General Motors has decided that certain 1998 and 1999 Buick Park Avenue Ultra, Riviera, Regal; Pontiac Bonneville, Grand Prix; and Oldsmobile Eighty Eight LSS model vehicles equipped with 3.8L supercharged engine (RPO L67-VIN Code 1) may exhibit a condition in which the starter motor may cause a gear engagement/disengagement noise or intermittently fail to operate and result in a no start condition. The cause is an oversize gap at the shift lever retainer channel in the starter nose housing. This may cause the lever pivot to move out of the retainer channel and result in the loss of engagement of the starter shift lever and the start drive.

To prevent the possibility of this condition occurring, dealers are to inspect the starter motor build date code, and replace, if necessary, the starter motor assembly.
