1996 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.

1996 GMC Suburban 2500 Reviews

I have a 1996 2500 454 with 192,000 on it. The biggest issue I have had is the front brake pads last about 30k tops. I do alot of towing, so some of the wear is to be expected. The only other issue I had was the distrbutor gear wearing out at 140k miles. The gas mileage on the HWY without towing is actually better than it was with my 5.7L 1500.

We bought a 96 Suburban used and the only issue we have had was some sort of module in the transmission had a bad ground wire. A fairly inexpensive repair kit solved the issue and the transmission is working fine now. The interior is nice and roomy and very comfortable to ride in on long trips. The sound system freaks out from time to time and requires us to pull the main fuse and let the system reset. Other than that, and the 454 big block which is hard on fuel, we are totally satisfied with this GMC product.
