    I recently had a blow out in my 2001 Denali XL. The tire damaged the shock and I was able to do the work to replace it myself. The Service Ride Control message showed up on my message center. In having the system checked to reset the message, we discovered the port was not functioning to reset the message. Anyone with knowledge that could help me... who has knowledge about this port or how to replace it? It is a dealer only item.

    Hello to all, Yes please help us out because I am having the same problem and my SUV is a 2005. Thank you all very much for any help, Michael
  • We are having the same problem and have been having it for over a year. No one can fix this. Did you ever get an answer? How do we fix this?

    Thank you

    Sorry about the late late reply. i have a 04 Denali XL(bought it new in 04), had the steering gear replaced at about 30k miles the problem was fixed. Had the same problem at about 115k miles, replaced steering gear again and steering shaft problem fixed again. Feel your pain with dealerships, the one here doesn't seem to know how to diagnose or repair and don't care about customer service and satisfaction. I recommend having someone check your steering gear and steering shaft.

    Has there been any resolution to this problem because I just had a factory unit installed in my 2009 yukon and it is doing the same thing
  • My 2002 Denali has had the service engine soon light on, on the dash for the last 150,000 miles. I have had it to the dealer several times and they have not fixed it.
    The error code that comes up is I believe 150. Any ideas how to turn this message off?

    In the last two days, my wipers have gone haywire in my 2008 Denali. They won't turn off; the sensor says to refill the reservoir (despite the fact it's filled); The wiper fluid won't spray (either front or back).

    I just had the recall work to disable the heated wiper fluid performed. I wonder if it's possible they messed up the wiper system.

    Anyone have similar issues.

    I have being experiencing a problem for months on my gmc yukon denali 2003. The traction control and engine light turn on follow with a message on the dash board that says "service stability, reduce power engine" It has done it for a while like every three months. I turn the engine off for a few minutes. Turn it back on and runs good. Thank God when it happens I have being able to pull out to the side safely. Please I need some advice what to do before I have to take it to a dealer where probably are going to charge a lot of money. I would sure appreciated ;D

    You have no choice but to take it to a dealer. Do not wait it is too dangerous.

    Sounds like a sensor is failing and it's dangerous. Happened on my wife's 2003 Denali and it was the MAP sensor at the end of the day but it almost caused an accident each time it happened. Took 3 strikes and the submission of Lemon Law docs to GM for them to figure it out and replce it. Never happened since and I'm at 89K miles now.

    That was back in 2004!! So, unless you have a good shop near you that you can call to see if they can service the sensors, GM dealer is the spider's nest waiting for your cash! :sick:

    Thank You OW
    I sure going to take it. I have been told if the engine light is not on its hard to figure out what is wrong do you know if thats true?
  • circlewcirclew Posts: 8,609
    You need to know the problem code. There is a computer at the dealer that can read the code. Most shops will tell you what the code is but not why it's happening. You pay for diagnosis and repair.

    Either way, if you can't do it yourself, you need to seek help from the best repair shop you know.

  • On a 2005 Denali, the voltage will drop after the car has warmed up. Voltage will stay low until you stop and restart. The alternator has been replaced. Any ideas or a fix?
  • am having problems keeping engine/transmission cool when pulling trailer with 2008 Denali XL. Anyone come up with a way to push some more air thru to keep it cooler?

    I took my 2007 yukon denali for the 2nd time to the dealer for the same problem. They replaced the battery for the 2nd time,but they tell me I have to pay $179 for the battery because it's now out of warranty. But they fail to realize that it's an ongoing problem. The case is under review by GMC as we speak. Is there a recall for this problem?? Somebody please help. I'm getting aggravated and frustrated with this. It actually had to jump start 4 other times before taking to the dealer. Please help...
  • Hi yong4. I got rid of my yukon denali. However I resolved my problem by getting a higher CCA battery. I got 800 or 850, I don't remember which one, instead of the 750 CCA.

  • I'm having the same issue with my truck.....any suggestions would be greatly appreciated :(
  • Hello! It's your denali not starting at all? Because didnt start at all and had to replace the fuel pump....

    I would recommend taking your vehicle to your authorized GM dealer of choice. They will be able to assist you in diagnosing your problem.

    Ever wonder why someone would ask about a problem first on this forum instead of taking it to the GMC dealer?

    Speaks volumes......hint, hint...

  • Let's see. Where to start. Bought my Denali because at the time the new Suburbans were not available or just out of stock. Had five suburbans previously. Loved every one of them.
    Soon after I Bought the Denali I needed a jump. Several jumps and a tow later They did fix the problem. Then the back stereo, heated seats etc. console had to be replaced. Then the rear window defrost cables (POOR DESIGN) fell or broke off the tailgate glass. Chalk that one up to 50-50 split. Poss. user error and poor design. Then the plastic Door handles started falling off. Are you kidding me. The driver side window switches stopped working and needed to be replaced. The wiper hose has broken three times. The Traction control system was malfunctioning. The Heated washer fluid system had to be disconnected as a recall item out of fears of a fire? The plastic cover on one of the mirrors just fell off after it was replaced. The auto-ride suspension had to be replaced. AT 30,000 miles I told them that there was something wrong with the brakes and front suspension, they found nothing wrong. At 34,000 miles I told them that it felt as if the front tire was about to get ripped off every time i hit a small bump. They found nothing wrong. At 36,000 same thing. Now I have 40,000 miles and they say that I need new brakes and rotors, new struts and springs, a new window actuator, the rear defog cable can no longer be fixed and the whole window would need to be replaced. Oh by the way your vehicle is no longer covered and that extended coverage you paid a lot for wont cover all of the repairs. You' looking at about $4,000 or more. How would you like to pay for this? Other than that I think I like the vehicle.

  • I have a 2004 yukon Denali and the heat does not work in the back. It works perfectky in the front but in the back only blows cold air. The A/C works in both the forn and the back but the heat is the problem. Anyone has any suggestions or past experiences with this issue? How did you solve it? Thanks
  • Please let me know what you find out. I have a 2000 Yukon the heat does not work in the front but the back works fine.
