1988 GMC Suburban recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Transmission / drivetrain
What's wrong, in plain English: The parts that send engine power to the wheels. Failure can mean a sudden loss of power or the car rolling away. UNANTICIPATED HEAT IN THE TRANSMISSION CAN FORCE THE TRANSMISSION FLUID OUT OF THE VENT TUBE.
What could happen: THE VENTED TRANSMISSION FLUID CAN CATCH FIRE IF EXPOSEDTO A SOURCE OF IGNITION.
The fix: INSTALL A LONGER TRANSMISSION VENT HOSE ROUTED TO THE LEFT SIDE OF THE ENGINE COMPARTMENT OF THE VEHICLE.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 1988 SUBURBAN.
- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 93V016000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

THE TIRE DEALER SAID THE TREAD HAD SEPARATED AND THE TIRE WAS UNSAFE AND SHOULD BE REPLACED. HE ALSO SAID THE RECALL HAD EXPIRED. HOW CAN A RECALL EXPIRE? I DON'T KNOW IF THE PREVIOUS OWNER OF THE VEHICLE WAS NOTIFIED…
