Known issues on the 1992 Grand Prix. The federal record holds 1 recall for the 1992 Grand Prix, involving certain 1992 Grand Prix vehicles with the 4-speed automatic transmission. A reverse servo pin could stick in its bore, causing reverse to slip or drag in drive, or leaving the transmission in reverse while the selector read neutral, so the car might roll backward unexpectedly. Dealers replaced the transaxle where needed; the campaign covered 10,141 vehicles. Owners have logged 114 complaints, 40 on the hydraulic service brakes and 30 on the electrical system, with 8 reporting a crash, 6 a fire and 4 an injury. The transmission, brakes and electrical system are covered with procedures, specifications and diagnostics.
