I have a 2002 Denali and really love the truck.. The one complaint that I have concerns wind noise that I only get at high speeds. The noise seems to come from the front windshield on the passenger side. The sound is best described as sounding like crunching plastic. Anyone else experience this.
Thanks
JN
I've been at 75 and its very quiet.

I had an ASC sunroof installed which needed adjustment which eliminated 95% of the wind noice I was hearing. Good luck.

I never really sensed any power loss, but I just couldn't stand the annoying kazoo-like sound.

I have a list of small items that need to be fixed, and I was just waiting to find all the small stuff for one visit. Here is my list.
1. Engine knocks when cold
2. Engine pulley squeaks (which one?)
3. 2nd row driver side seat heater doesn't work
4. Rear roof rack does not latch on passenger side
5. Rear hatch is very prone to not latching
6. Steering wheel off center... Just kidding!

I took out the extended warranty with GM, so we'll see what happens.
One other thing. Make sure your cargo mat/line is not preventing the liftgate from closing fully.
I have a 2001 Denali and this issue has been getting Progressively worse and now it is to the point that I am going nuts when I accelerate, it is a humming "Vrvrvvrvrvrvrvrvvr"( yes that is How it sounds dont make-fun ) sound when I am cruising and it is only when I press the pedal Accelerate the dealer put dye in the differential to see if their is a leak that may not be the problem , but I dunno it just has been getting worse and now It is time to do something about it , so If anyone knows what this may Be PLEASE post , because I dont Want to Have to deal with GMC going back many times trying to find the problem, Thank you very much.

The dealer should simply loosen the latches and move them closer to the interior of the vehicle by less than a quarter inch. That should do away with the inadvertent door ajar signal.
LOBSENZA & HEATWAVE3: Thanks for the insight on the latch problems, I will try to tactfully tell the service techs to try your approach!!!
I've almost forgotten what my new truck looks & feels like...... :<
This is my first post to this forum, though I've been following it intently for the last couple of months. My wife and I finally made the move two days ago and traded in her leased 2000 Acura 3.2TL/Nav for a 2002 Garnet Red Yukon Denali. All of the information that you guys have provided here was instrumental in our decision to go with the Denali (also considered Acura MDX, Cadillac Escalade, Ford Explorer, and even Range Rovers). We've been very pleased with our Denali in the short time we had it. I must also say that the Edmunds TMV figures and information aided the purchase process greatly. The dealer was trying to convince me at first the this vehicle sells about at MSRP, and the $2002 cash back was all I should be looking to get off of the price. But, as soon as I whipped the TMV printout out, the dealer changed his tune. I wound up negotiating to $1200 over invoice!
Also, the posts here also seem to be getting browsed by some folks at GM--I say that because many of the do-it-yourself upgrades (such as the relays for the auto-opening sunroof, the door unlocking when shifting to park, and installing map-light equipped dome lights on the rear seats) are already incorporated in the Denali we just bought (build date 11/01).
Well, my real question was: has anyone attempted to install the cargo cover from the Denali XL into a base Denali? It appears to have the slots right behind the second row seats to hold one, and the hooks molded into the rear interior panels at the tail gate to catch a cargo cover when extended. But the GM site I looked at (and the Yukon brochure) seem to indicate that the cargo cover is not an option on the base Denali, only the XL. Is this the case?
I don't know whether the cargo cover on my 2002 Denali XL will fit your base Denali but if you call 1 800 462 8782 between 0800 and 2300 hrs you can get an answer from GMC customer assistance.
What is an auto-opening sunroof?
Also was curious if the 02 Denali enables both the low and hi-beams to be on when you activate the hi-beams? Or do the low-beams automatically turn off when you activate the hi-beams? Do you have to turn the fog lites on each time or do they stay on the next time you start up the vehicle?
Fog lights stay off after re start.
1) I hear a strange whining coming out of turns from the front drivetrain. It only seems to happen at low speed ( either that or I can only hear it at low speed ) and tends to go away within a few seconds after straightening out the wheel. I'm assuming it's the AWD system .. I used to have a Jeep GC with the full-time AWD and heard all kinds of drivetrain noises but nothing quite like this.
2) I'm hearing what sounds like an electric pump from the rear when the car is running. I am guessing this is the Autoride, but I would have figured that this noise would go away after any load leveling was done ... of course it could be the adjustable damping .. .
3) I noticed something kinda scary the other day leaving a stop light .... the transmission seemed to slip for about 1 second before I let off the gas and then it caught and has been fine ever since.
Anyway, that's what I've noticed so far. If anyone has any input, pls let me know.
We've been averaging ~12MPG around town ... to put that in perspective my old JGC with a 5.2L ( 318ci) and full-time 4wd used to get about 12.5mpg around town. Color me impressed.

2) The electric pump sound is your auto leveling. However, it should only last for a couple of seconds immediately after you start the car or if there's a significant differential in cargo after the initial leveling. If it's constant, then you may have a problem.
3) My tranny slipped once or twice but that occurred within the first 1500 miles. Haven't experienced it ever since. Got 14k now.
That's my 2 cents.
Enjoy The Ride........

It was a couple minute check with the analyzer and they informed me there was an upgraded software program for the transmission shift "schedule". The upgrade was done while I had an oil change and it made all the difference in the world for me. Check with the dealer because it could be a relatively simple correction.

Other than the lag issue with the DXL which was correctly with the software, I have absolutely no complaints regarding the tranny, although its disappointing to here about those that have had issues. Time will only tell but as of 16K and a fair amount of towing, I'm quite pleased with the performance.
usa4evr: I'm not entirely sure but I think the reason the H2 has a different tranny than the Denali is simply that the H2 has a low gear option that is not available on the Escalade AWD or the Denali AWD. Both the Caddy and the GMC are the same tranny however the H2 gets the additional benefit of a low gear ration which required a slightly different trans design.
After review it seems both are 9005 one being 65 watts and the other 60 watts.
I had called two GMC parts departments and got the wrong information. They obviously looked up Yukon and not Denali.
I owe you one.
As a follow-up on my previous question on Autoride, I noticed yesterday that I get a loud 'electric' pump sound for about the first 15 seconds or so after starting up. After that there is a constant, softer electric pump sound that's present as long it is running. It is not noticeable from the cabin but if you get out you can hear it. Anybody else notice this? I didn't notice it on a regular YXL 1500 with Autoride.
Anybody have any comments highway mileage? Over the weekend we took the whole family ( 5 of us ) up to Mt. Hood from west Portland metro area. It's ~130 miles round trip from sea level to 6000ft and back. On the first leg of the trip we got about 16.5 mpg on flat ground ~65mph. For the whole trip average was 15.9 ... I was pleasantly surprised given the 12/15 rating on the truck. It's got ~1500 mi on it now.
I have heard the pumping sound,but only for a few seconds and never noticed it outside the vehicle, as the vehicle is usually off when i am out of it.
Sorry...I do get a noise at times when i start the truck in the morning. Sounds like lifters that need oil. Sort of a grinding noise. That's why i took the extended GM warranty..
