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.

My 1990 GMC suburban just quit while driving it. It lost electrical power and the only thing that works is the head lights. Is there a fuse or fuse link some where that has blown.

GMC Suburban 2500 Reviews

My suburban has been great pulling my travel trailer and loaded with family. Problem is it also has something always needing fixing. Looks like I have to get rid of it now -- the smog pump went bad and there is no replacement except for junk yards. this according to dealer, parts houses, AC Delco (who makes the part), and multiple internet sites trying to find a new pump

I own the 1998 GMC 4x4 2500 with a 454ci 7.4 or 7.6 L. This truck is a true monster. It tows better then my friends 2005 Tahoe. Steering wheel has too much freeplay, lights and electrical seem to have some sort of short, AC blew out at 170,000 miles. Besides that truck still runs and looks great at 174,000 miles. I did get the engine redone, fuel injectors seem to have been full of gunk. My check engine light won't come off, i will check it out soon, hope it passes smog this year. It always passed smog before. Gas is killer, going on a 3 hour freeway drive totoal 6 hours takes about $120 in gas at about 3.70 gas per gallon. But i luv the power and looks of this truck.

We have had the car for 18 years, it was purchased as a lo mile used vehicle.
Running a 454 CID big block it has performed very well and is good on gas.
Originaly we had a 28 ft trailer to hall cross country, didn't even notice a pull or
load on this chassis. My 350 cid truck boged down and was difficult to stop.

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.

i have 98 to with 454 . the only thing with my truck is whan i give it to much gas it discharges for about 30 to 40 sec.
