  1. I've had my Denali 6.2l 4WD for a couple of years and have put nearly 30k miles on the ODO. I jumped to it from a 2010 Sierra SLT Z71, which was a great truck. The issue with this Denali for me is the limitation of Magneride. My truck has tongue rating of 500lbs. I tow a small toyhauler, several sleds with all of the gear, extra gas etc. I also have small tractor and 20' flatbed leftover from my SLT days. I go on snowmobile trips every winter, towing trailer sled nearly 2000 miles each way, a three day trek, two lane. Pretty isolated, so need to take with me everything I need in case I happen to get stuck along the way. The route is sketchy at the best of times. Ice roads etc. The 3500 is overkill for what I need, but it is new, has the 6.6l diesel, LTZ and Plus package, sensors, heated steering, heated/cooled leather seats etc. No lane assist though, it isn't something I use in my Denali. Other than that, it is a crew cab like the Denali, is a Z71 and currently it is selling at a significant rebate. I've been looking for a while (still not certain though) for something that would handle more payload, handle the towing, and not limit my truck life otherwise... getting to my camp etc with all of the kit I have. I currently feel like I'm driving a car in a truck skin with the Denali. I may have made a mistake giving up my SLT but the 5.3 was too light for a long haul. Love the 6.2l though. I hope this is the appropriate placing for this topic. Thoughts appreciated.
  2. Had the transmission flush and fluid changed. Still not as liquid smooth as it was new but haven't had the kick so often between 1-2 and back. If it gets worse, I'll bring it back.
  3. I guess I'm asking for experience from those who have made the change in terms of the vehicle they drive, specifically the 6.2 and the 8 spd. I haven't decided on a change at this point. I also, don't want to void any warranty or give GM a chance to say I didn't follow their service specifications/oil etc.
  4. I used AMSOIL in an older vehicle because I read it was good stuff. I didn't keep the vehicle long after that so haven't the experience of seeing the benefit, which I do not doubt. I too am all in on the best oils and cold starts, heat etc. I tow a little, (3200lbs) or so, most of it during the dead of winter. I believe that maintenance is the key not only to longevity but also to performance. My question ref the transmission was specific to the shifting issues with the 8spd. If I can mitigate the problem by switching out the Mobil to AMSOIL, I will do it and the engine oil and filters too. I love this truck of mine and the 6.2 is smile maker.
  5. I have the same truck. Recent bulletin for 8spd transmission called for a flush and Mobil 1 Synthetic LV ATF HP fluid if you've experience rough shifts. Have you changed yours with this juice or have you used AMSOIL for the transmission as well as the engine oil?
  6. Had the same thing done a couple of weeks ago. Seems a little better. Shifting is nowhere near as quiet as when it was new. Keep going back until something is found to remedy it, I plan to.
  7. I've gotten 9.0l/100 km -- 9.9l/100 km ... highway, cruising 120km (75 mph) with occasional 130 (80 mph) to pass. Distance of 500 kms. I'm certain that it could be better if maintained 100 KPH.. (60 mph).
  8. I agree. If I could have, I would have bought an 8' bed crew in Denali trim but with a z71 package. Works for me.
  9. I have a 2017 Sierra Denali 6.2 4wd. I've only heard a clunk when coming to a stop at low speed just after a cold start. Doesn't happen every time, but very noticeable when it does. I've read some folks refer to something similar with their trucks. I've got about 20k miles on it.
  10. Other than the premium fuel requirement, I don't see a downside for the 6.2.
  11. Digging this up because I've a 2017 Denali and thought about putting a small ultra light camper in the box and towing a 23ft snowmobile trailer.. about 2,000 lbs empty but more like 5,000 lbs loaded. GM says not to put a camper in the bed. I guess it would compress the MagneRide too much and cause some of the concerns mentioned by the OP. I am wondering what the new 2020 model is like because I think that GM discontinued use of the MagneRide.
  12. It was a few years ago... prefer it though. Perhaps it should be an option.
  13. I currently have a 2017 Sierra Denali Ultimate 1500. Really dislike the blue in the dash, had a SLT that had red, so much easier on the eyes imo. Stepped aboard a 2020 2500 Denali diesel yesterday. Seating position wasn't as comfortable as my 1500. There is no peddle adjustment, the dead peddle angle has increased and limits stretch room for the left foot. Supposedly these vehicles have more space but it doesn't make them more comfortable. The seats could do with more adjustment, wouldn't hurt to be a little bigger and the steering wheel telescope could do with a couple of inches more adjustment. The stereo in this model was very nice sounding, full and rich. In terms of the AT4, I don't think you can get the offroad package in Denali spec. Belly plates, shocks etc... GM thinks that Denali's never leave the asphalt.
  14. I'm thinking about a tuner as well. Wonder if it is worth it and whether there is significant change. Would not send anything away to be messed with. I'd like to cut out the speed limiter, would like to tune for better towing when needed... if possible. Something easy to use, multiple programs.
  15. I have a 2017 Denali 1500 with the ultimate package, frost tri coat. I like the way it looks and sits from factory. Handles like a dream. Not sure what I'd buy if I jumped but I love the 6.2l, just not the fuel requirement. Can't get high test everywhere I travel so I have to can it when I do go off grid. I don't treat it like a car so would have liked some plates on the belly too. No factory option for that. Good luck with the lift kit.
  16. Sound like the tech messed up. Take it back and make sure it is entered in your profile. I'd write GM while you are at it in case something happens with your vehicle as a result of the water damage. Other truck owners have experienced water damage from the satellite antenna being replaced, tech bulletin.
  17. Had my 17 in to have the fuse removed in the fall. In my case, the dealer wasn't too proactive about letting me know (when a fix was avail) when I could bring my truck in for the update. I stopped at a different dealership while out of province, done, no bs. Both times, in and out less than a half hour. Can't be too much to it. My 2010 model didn't have half the recalls this model did, throughout the 8 years I owned it.
  18. I doubt very much they'll give me money back. And although I could do without the slider, I bought the truck with it. If I sell it, I'll put an ejection sticker over the rear window button and call it sold? Perhaps another class action is required to light a fire against GM.
  19. So it is the defroster in the slide that is the issue and fire associated with it. GM should at least provide a timeline for a fix. I hear you on holding my breath. Thanks. to both of you for your reply.
  20. I recently received a recall notice about the sliding rear window and an issue with fire. The recall said that the dealer would remove the fuse associated with the function until GM provides a fix. I questioned the dealer about it and they haven't heard of a fix but have said they replaced one window complete. I am bringing my truck in for service soon and it has two recalls on the books for it. The other is a software programming for brakes I think. Appreciate any thoughts or experience on the window issue. I've had the Sat antenna replaced so far under warranty but the truck has been issue free other than that. I apologize if this post is in the wrong location.
  21. I have the 2017 model of the same truck but with the short box. Love the performance but do tow a 19' toy hauler (5K LBs + sled and gear) for a sled trip most winters. My issue is the gas tank size... because there is generally regular gas not 91 or better where I travel,.. which is very rural with few communities and stations. I'd like to install a bed tank, even if I have to pump the fuel with an electric pump. Not sure what the regulations are on that but it would be worth it.. just for those winter trips. It is that or carry a dozen gas cans for the round trip.
  22. Me too. I find most vehicles today are made for short/small drivers. The seats adjustment isn't enough to offset the hardness in seat. I find nerve pain when driving distance of an hour. My 2010 w/leather was better than the Denali seats I have now. Not sure where to turn because it feels like industry is going the way of airlines, as if I care who is in the truck with me.
