2005 GMC Yukon Denali Reviews

Bought my 05' Denali new and it now has 99,100 miles on it. It's been a great SUV but it might be showing issues now. 1) I hate the fact the front seats don't recline all the way. 2) Electrical issues (radio turns off for no reason, bulbs burn out all the time, dash lights lite up like a Christmas tree and shut off for no reason, POSS Traction button engages for no reason. 3) AC/Heater doors lock in wrong position. Replaced them already at 67k. AC get hot when I want it cold and the Heater gets cold when I want heat. WTF?? 4) The water pump went out. 5) The rear defroster cable broke off. 6) The brake cable broke. For an American car, it's pretty good. Comfortable to drive and has great power but the gas mileage sucks! 10-11 miles to a gallon?? Time to trade it in.

I have owned my SUV since 2006 bought it with 15000 on it. Just roled over to 106K and my front passenger speaker took a crap. Can you even replace these speakers without messing up the stereo system in general. A/C got stuck on heat just on the driver side. So now truck has no heat but its a Florida truck anyway. Who needs heat? Everything else on this vehicle works great. I would definately buy another one.

Have had my Denali for 7 years and it has been a delight! Very few problems have occurred outside of the regular (tires, lights, and oil maintenance). I too have had some weird electrical occurrences: truck's off and door opened and lights and radio still on (have to open another door to cut all off). All-in-all, great truck. Now's time to get new paint job and tune-up!

Love my 2005 Yukon Denali. Owned it since new, keep it in mint condition but I have three weird re-occurances that I hope I can get some advice on because I'm losing faith in Mr. Goodwrench. 1. Climate control actuator misbehaving again -- pumps out heat when I want AC. 2. Electrical system has mind of its own -- when I remove key and open the door, radio and lights remain on. I have to open another door to shut off the radio/lights. 3. Poor solder job on the rear defroster wiring on the deck lid's window. Broken loose several times. Is there anything else that can be done. Stupid idea on GM's part to have two flimsy telephone-cord type wires exposed like that with some less-than-adequate soldering. Duh! Any help would be appreciated. Thanks for the heads-up on the brake lines. I'll be sure to look out for that since my truck's approaching 100k miles.

the wire that connects the defroster that one welded came off how can i weld it back?
