    This is my first post to this board. I am in the Atlanta GA. Area. My history is I have followed (and enjoyed) the board since I purchased my 2002 Denali (Shorty) in June of 2002. Anyway, since new, I have had many problems. They are as follows:

    1. Front end gear noise
    2. All interior lights flicker at idle
    3. Tranny hesitates when shifting from 1st to 2nd gear
    4. When leaving a red light, the tranny will sometimes fall out of gear, free rev the engine, and then bang in to gear (this is horrible for a AWD vehicle)

    However, the main problem I am claiming is the gear noise from the front axel because I can duplicate the noise every time. It drives me crazy!!!! GM kept my vehicle in the shop over 50 days and spent over $8,000 of GM’s money to fix. Nevertheless, they have yet to fix the problem. Finally, the Area Svc Mgr (I am in Atlanta, GA.) drove my truck and said it is supposed to make that noise. YEAH RIGHT! It is funny that the svc dept hears the noise and attempts to fix but he claims that the noise is normal. I disagreed and began the BBB Auto Line process. I am set to arbitrate on the 26th of August. Do you have any suggestions? Also, I took my truck to another dealership and acted like I knew nothing about cars and asked them to test drive. They drove it and put in writing that there is something wrong with the front end. Was this a good move to prove to the arbitrator?

    Any feedback from anyone would be helpful!!!

    Thanks in advance for everyone help!
  • My Denali had the same problem. Very frustrating since I bought it new and noticed the noise the day I picked it up from the dealer. Service dept. ended up calling GM engineering and traced the problem to a bad wiring harness, which was repaired instead of replaced. The entire center console needed to be removed.

    In doing so, they made a tear on one of the leather seats and failed to re-attach the center storage bin lamp. Service dept. couldn't "recreate the problem" regarding that lamp. I ended up disassembling the bin/console myself to find the lamp assembly tucked away where it didn't belong.

    Let me know how your repair goes.
  • Can you describe the conditions when the transmission hesitation occurs on your truck - light or heavy throttle? all the time or sporadically? warm or cold temp? Can you also describe the conditions when it slips out of and back into gear?

    I had the trans on my '02 Denali replaced when it was only a week old. It still doesn't feel right to me.

    Thanks!

    I could go on for days about the problems but I will try to keep it to the point! I, like you, have a 2002 Denali. My tranny details are as follows:

    1. Tranny hesitates when shifting form 1st to 2nd:
    a. Happens when cold and at normal operating temps
    b. Only happens under light throttle (never under hard acceleration)
    c. Feels as if it wants to shift in to 2nd by learching back and forth but doesn’t
    d. It stops once in 2nd gear
    e. Summary, GM claimed that the clutches were slipping in the rear end. They drained the rear end and filled with new oil and additive. This did not solve the problem.

    2. Tranny falls out of gear and slams back in gear:
    a. Does not happen all the time.
    b. Only happens after fully warm and have been driven for a while.
    c. It always happens at red lights. The light turns green; I hit the gas (with it in gear of course) the engine free reves and suddenly bangs in to gear. I always look in my rear view to see if I left any tranny parts on the road.
    d. Please note: If it ever happens as I attempt to merge in front of traffic I will either blow up the engine or tranny due to hard acceleration.
    e. Summary, GM cannot duplicate the problem so they have not fixed. Nevertheless, they claim that there is a TSB out there.

    I love the truck; I hate the problems. Why did you have the tranny changed in your truck? Please explain. Also, do you have problems with front gear noise of pulsing lights?

    I could go on all day but will not bore everyone!!!
  • During the first few days I had my truck, it would "slam" into first gear from rest like you described. Happened randomly. On its first long-distance highway trip, it was slipping between gear shifts and wouldn't go into fourth gear. I checked the trans fluid level and found it low. The dealer did diagnose clutch slippage and ordered a new trans. Took a little over 2 weeks before I got it back.

    I have 18K miles on the truck now and on rare occasions it does hesitate during the 1-2 shift.

    I feel the same way - I love the truck but hate the problems (I still have others).

    Good luck to you!

    Trip last week from Annapolis, Md to St Louis, Mo.

    Annapolis to Wheeling, WV. 16.1mpg, speeds 65-70.

    Wheeling to St Louis, 17.0mpg speeds 75. (lots more level ground).

    All from DIC on '03 YDXL, 3 adults, 2 little ones, rear full to roof.

  • I am an idiot. I assumed (from reading a review) that the 2003 Denali had Telescopic Steering, prior to buying one. Wrong! What a mistake! Even when I lower the pedals to the floor and move the seat forward - I still don't get the desired steering wheel position I would have with any other vehicle with a $51,000 MSRP (which obviously would have telescopic steering).

    I have a 2002 Denali that has a problem with the front axel whining. Has anybody with the same problem had GM perform the following fix?

    TSB: 03-04-17-005
    · Replace the front propeller shaft with an internally tuned dampened shaft*

    If so, please respond back and let me know what the results were. This seems to be a “Cover Up” solution. Why would the “front end” gears whine while the “rear end” gears are quite? I can’t seem to figure it out and neither can GM.

    As always, thank you for the feedback.

    My 2002 front axel disintegrated at 4000 miles. Almost everything under the hood was replaced by GMC. Now no problem and no noise. It appears factory and dealer didn't check front or rear axel fluid levels.

    I am looking for TSB 02-05-26-002 on the parking brake. Does anyone have a copy of it or know where I could get it?

  • Just had GMC dealer install GM Accessory exhaust tips (made for GM by Corsa) on my '03 DYXL. What an nice appearance change. The dual tips nicely fit in the space below the body from behind the rear wheel well to the rear bumper.

    GM would do well to make it standard issue on Denalis and Escalades.

  • lobsenzalobsenza Posts: 619
    They were standard until 03 when they were eliminated.
  • avolvofanavolvofan Posts: 358
    The exhaust tip that was standard until the 2003 models was a single tip. Compared to the "no-tip" 2003s, the single tip was better. However, compared to the dual tip Corsa, the single tip on the 2001 and 2002 models comes up a bit short. I have had numerous positive comments about the Corsa dual tip that I had installed on my 2003 Denali - the body shop manager at the dealer had the Corsa dual tip installed on his Yukon after he saw my Denali with the Corsa.

    whole Corsa system?
  • If you find anything about the technical service bulletin on the parking brake let me know. I recently installed new parking brake shoes and this system is really poorly engineered. Basically, the rear brakes are disc, but they have a drum rotor to accommodate the parking brakes which work like the older drum brake systems. There is a star adjuster, but no access to it through the rotor/drum (like on older systems). Essentially, you have to remove the rotor/drum and adjust the brakes based on an oversized vernier caliper measurement. This works well if you have a matching new set of drums & shoes, but with my older set, I had to give it a couple of tries before finding a setting that provided marginal holding power since there is slight wear on the drum. They still won't hold the truck on an incline, but at least there is some braking action. I had even slackened the line adjusting nut on the cable before installing the shoes and now have it tightened at the limit. The next major service I'll have a dealer look at it to see if they can apply more experience to this and improve the braking capabilities.

    This bulletin is being revised to add Suburban and Yukon XL models. Please discard Corporate Bulletin Number 02-05-26-002 (Section 05 - Brakes).
    Condition
    Some customers may comment on a scraping noise from the rear of the vehicle while driving. The noise may be intermittent.
    Cause
    Condition may due to the parking brake shoe contacting the drum in hat rotor without the parking brake being applied, causing premature wear on the shoe lining.
    Correction
    Replace the parking brake shoe and install a new designed spring clip retainer. Follow the service procedure below to correct this condition.

    I have not seen dyno results that show enough of a hp/torque improvement on the Vortec 6.0 liter engine to justify spending for the full cat-back system. If/when the exhaust fails after the extended warranty has lapsed, then I will be in the market for the Corsa cat-back system. Until then, I am quite happy with the dual tips.
  • Lobsenza, thanks for the TSB info. I did not replace the redesigned clip when installing the new shoes since I did not know about the recall. The linings I replaced at 40k miles were worn out indicating that they do drag on the shoe, so this is definitely a problem.

    I was curious to know if anyone has checked out EBAY lately. There are two “Denali SS” models out for sale. I like the equipment installed and plan to call the dealership to see if I could get one built. However, I wanted to poll the board first to get some honest feedback regarding the trucks looks, equipment, price, etc….

    Let me know what you think about the “Denali SS”

    Thanks!
  • I just got the results back from arbitration yesterday! In summary, I DID NOT GET WHAT I WANTED OR BETTER YET “WHAT I DESERVED”!!!

    The verdict is as follows:

    Give GM 30 days to fix your concerns. When repairs are completed, drive the vehicle for 30 days and if you are not satisfied we will reconveign the hearing and I will come up with my decision.

    This is how it went down:

    The hearing lasted 4 hours. (Wow, it was long) I gave my side of the case; GM gave their side of the case BLAH BLAH BLAH. GM did nothing but put up smoke and mirrors. Their main case was claiming that I purposely left me vehicle in the shop to create a paper trail. Please Note: Every time I put my Yukon Denali in the shop I get a Ford Focus to drive. Why would I NOT want to pick-up my car? Anyhow, I used the following problems to support my case:

    Noisy drive train: The arbitrator drove my vehicle and recognized the problem. She put in her report that the problem is a manufacture defect and that it impairs the safety, use and value of the vehicle.

    Flickering lights: The arbitrator drove my vehicle and recognized the problem. She put in her report that the problem is a manufacture defect and that it impairs the safety, use and value of the vehicle. I also submitted my “Police Warning” issued to me for having a unsafe vehicle. She acted like it was no big deal that I am driving an unsafe vehicle in the laws eyes.

    Tranny hesitates when shifting 1st to 2nd: The arbitrator drove my vehicle and recognized the problem. She put in her report that the problem is a manufacture defect and that it impairs the safety, use and value of the vehicle.

    GM had their rep drive a new Denali to the hearing to support their case. Reason being, GM claims that all my problems are CHARACTERISTICS of all Denalis. After driving my vehicle, we all drove the new Denali that the rep brought. It performed perfectly. No noises from the drive train, no flickering lights, and tranny shifted perfect. The arbitrator commented to GM and myself that my vehicle has several problems and the vehicle GM brought had NO problems.

    Overall, I felt as if I won my case. She recognized all my problems and noticed that the other vehicle (the one GM brought to the hearing) was flawless. Therefore, I was happy because I felt GM’s vehicle helped prove my case. Furthermore, the GM rep stated that he did not want to work on my vehicle for fear of making the problems worse. With all this said the ruling was to allow GM one more chance to fix my truck. Let me state for the record that they have has 3 attempts at fixing my truck and a 4th and FINAL ATTEMPT to fix the truck. Now, the arbitrator wants me to give them a 5th chance to fix the truck.

    Any suggestion would be helpful. I guess that GA Lemon Law is next because I do not want them touching my truck anymore. The BBB works in GM favor!!!

    Thanks for sharing your story. I hope everything goes your way even after the "5th" attempt. I looked at the Denali the other day and really like it but your story makes me very leary. If I get one, I'll do a "major" test drive!

    Good luck, Mark156

    Their main case was claiming that I purposely left me vehicle in the shop to create a paper trail.

    And where exactly would you be had you not created a paper trail? Did creating a paper trail cause the defects? Amazing!

    Any comments with regard to towing with '03 Denali XL with 6.0 litre.I am looking to purchase this type and pull a 28ft trailer.(5000lbs).Mostly in midwest,flatlands.Thanks.
  • I tow a 35oo boat trailer without difficulty. GM has a 24 hour test drive. Take one out and bring it to the trailer dealer and test the 2 together. I did that with the DXL and my trailer prior to purchase.

    The 04 Denalis get the exhaust flange eliminated in 03.

    We have a Prices Paid discussion but it's empty. Are Denali's that easy to get at discount or something?

  • Does anyone have this? What do you think? Is it worth it? I have one in my Acura MDX and looking at a Yukon LT or Denali and wondering if the Nav System is worth it. I love mine now.
  • Juice 22, I test drove the Red Denali SS with the supercharger. What an awesome truck. Fast! I took it on Hwy 51 and mashed the gas. I also did a few standing starts on some back streets. It throws you back pretty good into your seats and with AWD = pure acceleration. I spoke with the Tech who built it and he says he's gotton 14.2 1/4 times at the track and thats easy to believe. The sway bars make a world of difference. I stomped on the gas when making a right hand turn out of a parking lot and the SS hugged the corner tight. The salesman flinched as he saw oncoming traffic, but was also amazed how the big truck handled.

    I couldn't get the price down to what I could afford, but I did buy a denali that night with Mods at a sweet price. My baby is a:

    03 Garnett Red Denali
    Sun roof, 2nd Row Captains Chairs
    22" Rims with Toyo Proxes
    K&N Cold Air Intake
    Flowmaster Cat Back Exhaust
    Automate factory upgrade alarm
    $49,000

    I Love the sound the exhaust and intake make. Sounds tough. I haven't had it dynoed yet, but there's a noticable improvement in acceleration. The tech told me I should expect 15 - 25 additional HP and an increase in torque, especially in the higher RPMs, plus it sounds bigger and badder than my dads 345 hp slade.

    Next: supercharger - $6300 and hotchis sway bars - $1300. Brembo brakes - $1200.

    Whats nice is it's all covered under the warranty. My .02 when buying a car. Go late Friday Night right before it closes. I didn't sit down and talk prices until 9:30pm. They all wanted to go home and got me out the door before 11pm.

    -Adam
  • Sounds like you have a great truck. Does GMC back the warranty, or is it only through the Dealer? I've got a Garnet '01 with a K&N filter & stillen Metal Matrix pads, but otherwise stock. I have been eyeballing a whipple supercharger system, but for now I'll keep the $$ and stay with the current setup. Only problem I have with the truck is an electrical drain on the battery which I think is due to the aftermarket DVD system which has a short somewhere. Still troubleshooting that one. Otherwise, I really love this truck. Not as refined as other vehicles out there, but I still think this is the best package for the money.
  • eveything is covered under GM warranty up to 36000 miles or 3 years. I was told only certain brands are covered and they have to be installed by a GM approved tech. It costs a bit more for the dealer to do it, but it doesn't void the warranty.

    I got to test drive a supercharged model. I have to tell ya, that thing was fast. There is a huge difference in acceleration when you don't have tire spin.

    I would advise checking into an exhaust. It really makes the truck sound tough, like there is a big block under the hood
