GMC Yukon Problems

Miscellaneous -- Verified

The upper dash may crack, most commonly on vehicles in warm climates and exposed to a lot of sunlight. The common repair is to replace the upper instrument trim panel. Information on a technical service bulletin or extended warranty is not available at this time.

Miscellaneous -- Verified

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

Brakes -- Verified

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

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.

GMC Yukon Reviews

i have a 1993 yukon 2dr 4wd . its lifted and has 35 inch tires on it and runs great. 189k and counting , not a fan of the ifs system so much as it tends to wear out parts due to big tires way faster than a solid axle setup , but i upgraded all my cv axles and steering components to beef it up when the stock stuff wore out so shoud be good. plenty of room easy to work on and cheap parts , cant ask for much more

2003 Yukon SLT. About 3 months ago my "low coolant warning" signal came on. So I took the truck in, they topped it over and said to just monitor it till I brang the truck back in a few weeks to do my routine oil change. A month later, sensor went off again. So I took it in to do a pressure test. They said the test came back okay, but that most of the liquid in my reservoir was water. So I had them do a complete flush and refill. Its been about two months since I've done that and my sensor has gone off again. I checked the reservoir in the morning, coolant was up to line on reservoir. Checked for any leaks from hoses, etc. no visual leaks from hoses, etc. No visual drips on ground. I went to check it again in the afternoon and the coolant went down about 1/2 inch. I don't know if just opening the reservoir will do that? But, I can't figure out what's wrong. It can't be a bad sensor because when I top it off, the sensor doesn't come back on! Any suggestions on what could be wrong?

2006 GMC SLT love this truck no problems rides very nice, wish i could buy a new one. best truck for 10k, can't get enough of driving this truck

I've just been told that I need a new transmission. My yukon only has 101,000 miles on it and has been well maintained. Any suggestions of what could be causing hesitation when going 50+ MPH instead of a new transmission? What should the cost be for a transmission?

I love my Yukon, its rides smooth and is very confortable seating, overall i love it.
