GMC Yukon and Yukon Denali Problems



  • I have been annoyed by my front end whining since my 2003 Denali was new. The dealer told me some are louder then others but everything is fine. I can't stand it. It is worst when you ease off the gas around 60mph. With a whine like that, something metal has to be wearing out and I'm sure it won't be cheap when it does.
  • FYI, in this case it was the turn signal switch, which had shorted out.

    I just got mine out of the shop today.. 2001 Yukon XL Denali with 67,000 mi. Sounds like I'm almost the same mileage. Mine was built in Nov/Dec 2000. How about yours.

    I'm fighting with the dealership (no luck), 1-800-GM-Cares (no luck) and waiting on the regional rep to call back to see what he is going to do. I'm researching arbitration at this point and researching as many occurences as I can find on the web. My repairs were $1900. What did yours end up?

  • I traded my 1999 Denali in June with 70,000 miles and praying that it would make it to a dealership that sold imports. The GMC person that I talked to wouldn't offer me one penny towards repairs. I hope that things turn out better for you. My regular mechanic told me that he is making a ton of money on all of the repairs. My Denali had major safety issues and after reading these messages I believe it was in some kind of electrical system failure. I wish I could be of help to you in some way. The Denali is a very frustrating vehicle. Good luck and stay safe.
  • I've got an 03 denali as well. When you say whining, what exactly do you mean? When I start mine and put it in gear and drive away I get somewhat of a whine in the front end as well. I feel a slight vibration (is the best way I can describe it) in the gas peddle that seems to go along with it. My father has an 03 XL and I don't feel this with his. I have extended warranty but haven't bothered yet. It doesn't seem to take away from proformance. Any luck with yours? Any symptoms like mine?
  • How many oxygen sensors are on a 99 yukon denali, and how many should be changed after 65,000 miles?
  • my drivers side seat heater dont work, the fuse is good, and the switch on the seat seams fine. Did anyone have this problem, or know how to fix it?

    thanx, tommyoo

    I currently have an 01 denali and i also am experiencing the front end nosie. The noise is one of the most aggervating things i have experienced in a vehicle.It doesnt do it everytime I drive it, just most of the time(mainly at lower speeds) I have taken it back to my to the dealership and they informed me the problem was normal, it wasnt normal when I shelled out 50 grand for the vehilce. I have yet to be able to find a solution to this annoying problem. If you have any suggestions please help.

    Probably a heating element. Mine went out last spring. You have to take the seat apart to fix it. Fortunately, mine was covered by my Chrysler extended warranty.
  • Just picked up my 2002 Denali with 27K on it from the dealer. New transmission, torque converter and radiator. Total expense $3,652.75. I am told the problem that required replacing the tranny was due to a leaking of coolant from the radiator into the transmission. I guess I would waste my time trying to get GMC to share in this expense. Any suggestions or advise. Thanks

    I heard complaints from my Dallas friends about Sewell. For the price of the Denali, it should be trouble free....or at leastnot as much as what you been through.
  • That front end noise your hearing is in the Diff..Just had mine serviced/rebuilt under warranty though....
  • Did you have any luck fighting this? I have a 2001 Denail (short) and my wife states that the transmission would rev up like it was in neutral before it would lock in. We have 80k miles on it. I don't drive it much, but I will take it out this weekend and see if it happens to me. This doesn't sound good.

    I have a 2004 Yukon Denali. Where in the heck is the fuel filter located? Can it be replaced by this handy do-it-yourselfer? If so, do I need to purchase any special tools?

    I have a 2003 Yukon Denali with about 30k miles. I have had it in the dealer 3 times over the past 9 months with door lock problems.

    1st visit: Right Rear door would not lock with remote or front controls. Could manually lock and door would unlock automatically.

    2nd visit: Both Rear doors would not lock with auto systems. Would unlock OK. Replaced all 5 actuators (sp?)

    3rd visit: Both rear doors and hatch would not unlock or lock. There was no way to get hatch open as there is no manual lock or key hole to open. Had to load and unload my truck through the side door several times = real pain. This time they replaced another part that was shorting the actuators

    I've had the truck back about 4 days with normal operation. Noticed that both rear doors are not working again yesterday!!! Anyone else have any problems like this?

    Went thru the same problems except gm covered mine had about 40,000 mi.
    Changed Trans, Radiator, torque conv.

    I have the Gold extended warranty but the dealer overroad the original warranty sayng there was problems with the radiators leaking antifreeze into the trannys. Gm covered it on the original warranty, so it may help to try and see if the dealer can override it.

    I also have been battling with the Noise in the front end. So far the dealer has changed the Front Differantial bearings. That lasted about 2 weeks, he then changed out the whole front differantial with a new one under warranty. That lasted awhile but I think it is acting up again. The front rubbing/scraping noise is getting louder and I can feel it in the floor.

    I am also battling a vibration that has been going on now for the last 35,000 miles.
    After 3 sets of tires and about 4 months of the dealer blaming the tires and the Tire shop blaming the dealer, the dealer put some weights on the exhaust muffler and this helped the reverb from the vibrations but the original shake is still there.
    I have about 5,000 miles left on warranty and I am about to park it in the dealers lap and tell the bank where it is (gmac, that should help them find the problem). I don't spend 50,000 for a truck that I cannot trust to go on a trip across country if I need to let alone just getting back and forth to work on time.

    Good luck with yours, but I think you made a mistake buying GM. I cancelled my order for a new Solstice and will not buy GM anymore. It' sad that one cannot afford to buy GM anymore and help support our American workers, but Japan will get my new business.

    Sometimes, when I start my 03 Yukon XL Denali, there is no sound coming from the stereo. The lights are on, the stereo can change from XM to CD to FM, etc., but there is NO SOUND. It is like a 'mute' button has been activated. Any ideas??
  • I had a similar situation in a 96 Tahoe that turned out to be a short in a rear speaker. That short resulted in none of the speakers working.
  • I have had this happen as well. There is a 30 amp fuse under the hood for the amplifier that tends to overheat. Usually pulling the fuse and re-inserting it will do the trick. If that does not work put a new one in and everything is back to normal.
  • I have an 01 yukon denali with 70k on it and the dealer says i need fuel induction/throttle body cleaning and new fuel filter. Cost is $170 to do this. How important is this procedure and do i really need to get it done? Let me know what anyone thinks.
  • tdohtdoh Posts: 298
    It definitely wouldn't hurt to get both done--especially the fuel filter, if it hasn't been changed at all--given the number of miles you stated...and if the TB also hasn't been cleaned at all, you'd be surprised as to how much gunk is probably lining the TB opening. Sounds like you're a bit hesitant do get it done, seeing how you mentioned the cost that was quoted to you.
  • thanks for your input. i am going to go ahead and get it done.
  • I have a 2001 denali and will be getting it out of the shop tomorrow. My tranny took a dump that cost me $3900 to rebuild. It was more than a standard rebuild. my mechanic said it wore out things that should not have worn out. Is there any success inj talking with GMC corporate or is it a waste of time??? not sure what to do, any input would be great thanks
  • I have a 1999 yukon denali GREAT TRUCK however i am experiencing a small problem I had my truck aligned when i left it continued to pull to the left horribly bad. I switched the front tires to see if it was in the tires, however the left tire is wearing down on the outside and so is the passenger tire. When i swapped tires the pull moved to the right. So naturally i thought that the tire is bad. I was told that shock absorbers can cause this problem and i dont want to buy a 600 dollar set of tires foir this problem to ruin them as well any suggestions?
  • i have the same problem on my 2004 GMC Sierra, the passenger side works fine but when i turn the drivers side on it shorts out both sides. I also checked the fuse and it is good. can anyone help?

    You didn't state the mileage of your Denali. At 6 years though, I'd say you are overdue for new shocks.
  • alcanalcan Posts: 2,550
    Outer edge wear on both front tires is usually due to excessive positive camber, toe in, or both. Could be just within specs and still show the same wear patterns. Would be interesting to see the actual printout of settings.
  • I have a 2002 Denali. I am havbing problems changing the cabin air filters on the vehicle. Anyone have any recommendations?
  • obyoneobyone Posts: 8,054
    What is the problem? Shouldn't take more than 15 minutes to do.
  • My 2003 Denali did the same thing. I brought it to the dealer and they had to upgrade a program in the computer. While I had it at the dealer they also took care of a couple other problems that were on service bulletins - Loose bolts on the drivers seat, and a high pressure valve in the power steering pump
