#15 of 26 Re: before putting 2003 denali on jack stands [03pimpnali] by rsht May 25, 2009 (4:02 am)
Replying to: 03pimpnali (May 23, 2009 2:29 pm) Hmmm, not sure I understand why your were told to disable the shocks...? I could be wrong, but below is my thinking out loud on why I can't see that is necessary. Just thinking out loud : 1. You must have one of those OEM Auto-Ride systems. 2. In the event that you need to change a tire due to flat (or raise the vehicle for a tire rotation), you have to first jack-up one of the wheels, does your Owner's manual says you need to disable the auto-ride system (in my 2007's manual, it does not; but if for your model year is Yes, then most likely you just found the instruction on how to disable the auto-ride system). 3. Skip the #2 thinking above. The auto-ride system is to pump air in to the shocks when they are compressed by the carrying weight/load to your vehicle, the pump stops when the vehicle reaches back to the specific/normal ride height (distance between the axle and chassis/frame) via a position sensor/switch (for example, normal vehicle ride height is 8" apart between the frame and the axle, now with load its down to 7", so as you turn-on the ignition, the auto-ride system triggers the compressor to pump air in to your shocks until the ride height is raised back to 8"). As you raise the vehicle on to jack stands, if you rest the axles on stands then you have nothing to be concerned with as the ride height/distance between the axle and the chassis is the same as if the vehicle is sitting on its 4 tires. Agree? Let's say you rest the vehicle on the stands by its frame, that means the axles will drop down (longer distance between the axles and the chassis than normal), as your turn on the ignition that should not trigger the pump to turn-on, would it? I would think not...   Anyway, to play it safe, there seems to be two ways to disable the system: 1. remove the auto-ride system relay from the fuse block in the engine compartment 2. or by disconnect the Auto Level Control (ALC) Air Compressor connector in the rear of the vehicle. You first need to locate the compressor and follow the wiring and you should then locate the connector (most likely via those plastic anchors anchored to the back of your rear bumper close to the spare tire... Disconnect either, then turn on the ignition for 45 seconds and make sure the compressor is disabled before put it on stands. Be Safe!
#16 of 26 '04 Yukon Denali traction active issue by rainmaker1947 Jun 03, 2009 (7:01 pm)
My wheel bearings were replaced so that should not be the problem but if it pulls and makes a loud sound when the traction active comes on for a brief moment then leap frogs and the noise and display goes away is it more likely cleaning or replacement? Thanks. We went on a long trip and did not have the problem. Before and after the trip in town we do have the problem. Would an uneven tire pressure have anything to do with the problem?

Replying to: rainmaker1947 (Jun 03, 2009 7:01 pm) For having a difference in the tire pressure to cause this problem, it will have to be quite a few PSI difference between the left/right tires... (I am assuming all tires are all the same size). Assuming its not the bearing and you are one of the DIYer, have you checked the condition & level of the axles fluids and also the transfer case fluid? I would start from the basics and not too dirty at the speed sensors at each corner before spend the money to replace anything.
#18 of 26 2003 Yukon Denali Traction Active, Hatch Window, Speedometer by mxmama101 Jun 15, 2009 (6:00 pm)
No wonder GMC is in trouble--they never admit thier mistakes and make consumers upset! In the last month our Yukon's speedometer cluster dropped off the reading and other instruments in the cluster (step motor) Got that fixed for $200 in Toronto; this week more surprises before our holidays to the OBX. The traction active started; took it to the GMC Dealer JACK MAY in Ottawa--they charged 200 to clean the contacts plus 100 to UPGRADE the software which accidentally tells the computer there is a problem when there isn't. Leaving their shop I almost got totalled by a truck as I tried crossing the highway! $350 and still the same issue! At the same time our Rear Hatch window fell off the hinge on the right side. We have MAYBE used the window 5 times since we bought the truck! The Dealer told us it is a $1400 fix, that we need a new window! All three issues are well documented with users. They are all SAFETY issues. I never mind paying to replace worn parts but this is unbelievable! We can put men on the moon but cannot reattach glass to the hinge like they did in the factory. Has anyone found solutions for any of these? I am going to try the JB Weld posted here but would like more details. Thanks.

Replying to: isi (Mar 12, 2009 11:53 am) I've had the same problem for the past year. Thought I was going crazy. Manual and dealer said it was normal. Started occurring every once in awhile at around 70,000 miles and has now grown to be a constant problem. First only Traction Active came on with power loss as everyone else experienced. Now effects the ABS regularly as well. Anyone have any luck getting it fixed as part of the recall?

Replying to: denaligirl (Sep 21, 2009 5:10 am) Your wheel speed sensors need to be cleaned. It is a pretty simple repair by the dealer but time consuming. The dealers don't seem to like making the repair though. I found out It was a recall on some of the vehicles but not the Yukon. It costs about $500. I paid for the repair and then wrote a complaint letter to my dealer. The service mgr at the dealer was able to get the zone service mgr from GMC to cover mine.   FOLLOWING IS A COPY OF THE LETTER I WROTE:   RE: 2003 Yukon Denali Vin XXXXXXXXXX   I recently had my vehicle in your service dept. for an on-going problem of which XXXXXXX GMC could not repair. From a standstill, when I would accelerate, the vehicle would lose power and not move after about 20 feet or so and a “Traction Active” message would appear on the display. This was a very serious safety concern as the vehicle would end up in the middle of the road with loss of power. It was an intermittent problem but would happen when I would drive through a stop sign or red light. To regain power, you had to let off on the gas peddle and the drive would re-engage. This left me twice in the middle of an intersection almost causing an accident at State Route 18 & Heritage Woods Drive, only one mile from my home. I would no longer allow my wife drive the vehicle due to safety concerns.   I explained my situation to your Service Advisor, XXXXXXX. She immediately knew there was a problem with the Stabilitrak System and scheduled me in for service. Your Service Technician spent about a day and a half with the vehicle and did a great job diagnosing and correcting the problem, which was cleaning and recalibrating corroded wheel speed sensors. This repair cost me approximately $495.00.   When you spend that amount of money on a repair, you like to know what the problem was, especially when another dealer had the vehicle twice and was not able to correct it or stated as XXX GMC did, “there is no repair for your problem”. GM recommended a repair procedure be followed from an ABS recall document ID # 1819672 of which the subject is “Product Safety – Front Wheel Speed Sensor Corrosion #05068B. In this recall it states the follow condition:   “ General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 1999-2002 Chevrolet Avalanche, 1999-2002 GMC Sierra, 2000-2002 GMC Yukon, Yukon XL vehicles located in areas listed below (which includes Ohio). These vehicles may have a condition permitting corrosion to occur between the front hub/bearing assembly and the wheel speed sensor. If the brakes are applied while the vehicle is traveling at a speed of greater than 3.7 mph but less than 10 mph, the corrosion may cause an unwanted anti-lock brake system activation. If this condition occurred where stopping distance is limited, a crash could occur.” (Continued on Page 2)   Page 2 - 2003 Yukon Denali Vin XXXXXX   Now, it seems rather clear to me that I had a safety issue that a crash could occur, as it almost did twice. And, it seems rather clear that the problem was the corrosion of the wheel speed sensors that caused the Stabilitrak to malfunction which activated the “Traction Active” which caused my vehicle to stop in the middle of an intersection. What does not seem clear to me is why General Motors would not pay for this repair as it is caused by the same corrosion of the wheel speed sensors as in the recall for the ABS.   Yesterday the GM customer service people called me and we had a very frustrating conversation. They said that the repair I needed was not related in any way to the recall even though the correction was the exact same as in the recall. They said they would conduct further research before a conclusion is drawn. It was very troublesome knowing that GM had customer service people making decisions regarding mechanical repairs that did not understand what they were saying. They have no mechanical background to understand what the sensor is or how or why it works. I told them to look on their computer screen to see the vehicle repair history and compare it to the recall. They said they do not have access to a computer. I said I’ll fax you a copy of the repair order and it says the same thing as the recall. They said we have no access to a fax. I said I’ll fax it to a Kinko’s close by and they said that was ridiculous that I would expect them to pick up paperwork from a Kinko’s. Obviously their call was not made to satisfy the customer.   If GM chooses not to pay for the repairs, it is apparent they do not care about me as a customer and I will take my future business elsewhere. I don’t care to drive a Japanese made vehicle because of the line of work I am in, but, GM will make that decision for me.       I would like you to know that I am very pleased with your service department and you have gained me as a service customer through-out the remainder of my lease. I am hopeful this issue can be resolved so that I can continue on as a future GMC Denali owner.   Also, just to let you know, I did end up buying a new Denali in 2007 and absolutely love the vehicle.

On mine it turned out that the front left wheel hub was loose and needed to be replaced. Once it was replaced the problem was fixed. Dealers want about $450 for the hub and another $200 for labor. It was interesting that my rear brakes were worn as well and needed to be replaced, however the fron still had over 50% of the pads left. The problem with the wheel hub was kicking in the ABS shutting down the front brakes so the rears were doing all the work.
