1992 GMC Suburban 2500 Problems

Miscellaneous -- Verified

The power door lock actuators may become slow to operate or stop working completely and require replacement.

Miscellaneous -- Verified

The inside and outside door handles are prone to breaking.

Engine -- Verified

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

Brakes -- Verified

Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.

Heating & Air Conditioning -- Verified

The quick-connect fittings for the heater hoses tend to leak engine coolant. This problem commonly occurs because the metal housing has become brittle, which can break and cause leaks.
