Two problems related to door latch have been reported for the 1999 Buick Park Avenue. The most recently reported issues are listed below.
Outside door handles on rf, rr, and lr failed. Mechanism inside of door broke making it impossible to open from the outside of the vehicle. Emphasize that only the lf door could be opened from the outside. In the event of an accident, it would have been necessary to use extraordinary measures to reach occupants. Rf, rr, and lr door handles all failed in the exact same manner (plastic component on door handle cracked/fatigued). Condition was corrected by replacing door handles. No obvious design enhancements were observed on replacement parts. Failed parts are available by request.
Door could not lock or unlock with key. Dealer has repaired door four times. Consumer continued to have the same problem. Please provide further information.
