GMC Yukon Denali/XL Autoride Suspension

keithb4keithb4 Posts: 2
I have owned an 03 Denali for two years. Recently whenever I start up, I hear a motor running which sounds like a compressor from under thr rear of the car. I believe this is the Autoride feature. Thing is, when I first bought the car, it would only run if I had a load in the back, or put a trailer on. Now it runs every time I start up. Ideas?

    Sorry, I can not speak exactly to your model year as I have an 07 Denali; but, with my 07 Denali, the Autoride system does run for a few seconds each time I start it up. The system also releases air out of the system when I turn the ignition off, which lowers the vehicle by about half to an inch... With your Autoride system, I would say the key is to make sure that the compressor stops running after a few seconds of pumping; if it runs all the time or runs periodically every few minutes (while the engine is running with the vehicle parked), then I would be concerned about a possible leak in the system... Let's hope this is not the case as each replacement OEM Air Shock is in the $300+ range... ouch!
  • Thanks, that confirms my suspicions that I have a leak. It runs for about 20-30 seconds every time I start the car, and randomly while I am driving. Looks like I need a trip to the mechanic.

    Thanks for your help.
  • Hi all! I have an '02 Yukon XL w/ autoride. My front right and left rear are shot and need to be repaired. I have been told by 2 separate mechanics that I need to replace all 4 (not just the two bad ones) b/c of the design. It will cost me in excess of $2400 to fix this. My car is sitting at 113K, recently replaced the entire intake manifold, had the throttle body replaced, new brakes, and regular maintenance. I am, over all, worried about final cost.

    My choices?

    1. repair and keep the car til it dies a miserable death b/c fixing the suspension will get me at LEAST another 75K miles!

    2. Trade it in and buy a new-to-me one (maybe an '05 or '06) b/c the cost of repair is more then I should pay given the value of the car.

    3. Other -- b/c there is always an other

    Help! What would you do and why? Thanks for the help!
  • Yup! That is exactly what it is Keithb4... Mine was doing that and it was a leak.

    Parts wise for both rear autoride shocks are around $600 at your local GMC dealerships (its about $100 less per shock if you get them other than your local GM dealerships), as price for the front pair its the same story; so for all 4 shocks, the parts price is at about $1200, that means the remaining $1200 are mostly for labor... which in my opinion is a bit too pricey. I tend to agree about replacing all 4, but, not at the labor rate they are charging.

    Assuming you only need to replace all 4 Autoride shocks (no air line leakage or compressor and position sensor issues), you may consider an option #4 if you feel up to it, that is to order your own parts/shocks and have the mechanic replace them for you. Check out the store in the URL below (just found this place a couple of days ago...) where you can purchase the exact same OEM shocks for the front (Part Number 00GMOEF) and rear (Part Number 00GMOER)... Good Luck to you!

    BTW, if you do choose option #4, be sure you have all the right shocks before going to your reliable mechanic. The part numbers I had in the post were from the Arnott site, double check with them for your specific model before ordering...

    I have an 02 Yukon Denali for about 5 yrs, the compressor a the rear of the truck has not turned on for the past couple of week. Is my compressor bad and is it an easy fix?

    Check the fuse first.

    I have the same problem on my 02 Denali XL. I tested all the fuses, no bad fuses. I don't see a label that clearly indicates a "auto-ride" compressor or any other variation that I would relate to the suspension. Am I not the master of the obvious or is there another name for the auto ride fuse? The truck now sags just a bit when it is loaded. I don't notice any big change in handling, it just does not sit level at all times.

    My 2002 Yukon XL did not pump up to level yesterday when I had a load on. Where is the fuse for the compressor located.
  • dbrown6dbrown6 Posts: 4
    Under the hood over the left fender. Mine was good. Either I have no bleed down or my pump just doesn't work. It's cheaper to have a failed pump!

    Checked the fuse and it was OK. I will check the levers that make the compressor engage. I do not have any message at the dash saying anything is wrong.

    Not knowing your particular Year and Model, your vehicle probably has the factory Auto ride height adjustment system (aka Auto Leveling system); some where in this system there is a fault, which the display is telling you to bring it to your nearby dealership for service. The fault can range from a leaky component (air hose, one of the air shocks), a bad height position sensor, electric connection to your on-board compressor to a bad compressor and etc... Hope its nothing serious. Good Luck!
  • I agree with previous poster. I had the exact same problem it was really problematic. When you have one bag that is leaking, you have to replace all of it. I took it to about 8 different people for estimates for repair and the best deal I got was $2000 to replace the air ride suspension or $1500 to buy the parts and have someone completely remove it and just use regular shocks. Good luck!

    Take a look at this place called Arnott, they carry the OEM shocks and components for quite reasonable price; but we have to find and do the repair ourselves, or pay more $$$ for others to fix.
  • which fuse is it?
