I'm beyond frustrated... not home a week and the "fix" is leaking transmission fluid on my driveway. Can't get the dealer that did the repair to return my calls either.

Got it back yesterday. Driving normally post repair, but took it to a Ford dealership for trade in evaluation. I've been a GM guy for years, but this experience has put me off. With the engine replacement, brakes and now transmission this truck has been in for service for over 4 months of my experience. All within 27k miles. I've ordered an F250 platinum with a 7.3L gas engine. Done with this thing.

Finally have a diagnosis. The stator shaft support assembly needs to be replaced. Parts on order, hoping to be in next week. No loaners available so currently without a vehicle.

Getting the GM run around. One dealer confirms they hear it, but don't have the staff to handle the repair. The second dealer at first claimed its normal operation, so I had to go out and drive the truck to normal operating temperature for them so they could hear it. Sounds to me like the flywheel or perhaps the starter tapping the flywheel. Hearing again they don't have the staff to do the job. So going to a third GM dealer now. What a pain in the ass.

Hi all: Been a while as I've had a relatively decent run without incident. Recently started hearing a ticking sound by the front driver side wheel well in my 2019 Sierra 1500 (6.2L with 10 speed). Took it in to my dealer and they isolated to the transmission but don't have a transmission specialist on staff right now. So taking it to another dealer Thursday. Anyone else run into this with their trucks? Doesn't do it on cold starts, just when at normal temps. I had an engine replacement at 6k miles (27k now) due to the oil cooler line issue; had the whole brake failure issue a couple of years ago as well. Starting to think I need to cut bait on this truck.

Late in adding the pictures. Made some upgrades in preparation for the Airstream I have on order. Added the Brembo brakes and two 1,000 pound leafs to the leaf packs. Considering changing to 20-inch wheels with E load rating/10 ply tires as well both for towing as well as the fact that I'll be spending some serious time on the dirt roads of northern Maine this summer. If there are any 20-inch wheel guys in the Chicago area looking to swap into 22-inch wheels we might be able to work out a trade. The wheels and tires in these pictures wouldn't be the ones I'd be swapping; these are my winter wheels and tires.

I found a set of winter tires that match the factory size for 22 inch wheels. Mounted them to a set of suburban take off wheels. Toyo Observe G3 Ice. I've run them three winters now and they work much better than the stock tires (I also toss a few sandbags over the rear axle when I know bad weather is inbound). They can be studded as well; sadly I can't do that in Illinois (I miss having studded tires from my days in Maine). Edit: This appears to be another stock size option for you as well: https://www.1010tires.com/Tires/Continental/IceContact+XTRM/03477130000?vehicleid=185582

I'll add some pictures later after I've washed the truck, but I added a couple of mods for towing to my 2019 Denali. First, added the Brembo brake upgrade. It's pricey, but wanted the added stopping force. Love the look too. Definitely a lot more grab and a lot less pedal squish. I also took it to a suspension shop and had a 1,000 pound rated leaf spring custom molded and added to both of the stock leaf packs. It definitely rides a little stiffer; not harsh, but stiffer. Added rake to the stance which I'm good with since the truck sat pretty level prior anyway. I'm towing a 27 foot Airstream, max weight of 7,600 pounds and tongue weight loaded of 870 pounds. To that I added a ProPride hitch which, when loaded and on the trailer, upped the tongue weight to 910 against my 930 limit. That's before cranking up the weight distribution bars. Note, I won't use the added spring as an excuse to overload the rated hitch weight or payload; I'll be keeping the pickup bed pretty much empty when towing. But I anticipate a reduction in porpoising effect I still had on occasion even with the weight distribution bars cranked up. I won't be towing again until spring so it will be a while before I can report on the experience.

They did, it's the truck not the trailer. Fuses are present and all good. Going to the dealer Tuesday.

Didn't think of the fusebox (slapping my forehead). Will check that next before taking it in.

Hi Guys: Bought an Airstream to tow behind my 2019 GMC Sierra Denali (added a leaf spring package and the Brembo brake upgrade to assist with it, but that's another topic). Anyway, the truck doesn't recognize the trailer nor any tester units. Only the 12v power works; none of the signals/lights (rechecked with a multimeter and the same). I've checked the connections and grounds and as far as I can tell everything is fine. I've checked it both with tow/haul on and off; same deal. Before I throw my hands up and make an appointment with the dealer is there anything obvious I'm missing? Thanks!

Cool. DM me an address.

Folks... my wife gave me a set of red mpg caliper covers that say "DENALI" on them. It doesn't really work with my set up. So... if anyone here wants them just reply and let me know. I'll ship them to you. No charge.

Not that it helps you now, but you hold down the start button without your foot on the brake for 15 or 20 seconds. All functionality other than the engine running. Ask me how I know..... Had lots of time to read the owners manual while waiting for a tow truck for the very same failure last April.

Added a cold air intake to feed that new Borla ATAK exhaust.

Borla ATAK catback install. This video is me surprising my wife ... I was about 75% sure she'd hate it, but she loves it. Today was the nicest day yet in the Chicago area this spring and she had me drive her around with the windows down. ? https://video.nest.com/clip/5803c0b019d4424784119ab4d88585f9.mp4?fbclid=IwAR3WLZ7sW1rENbAznhzCPmwenqqJpHbkVFUyuDP5mFgUDIE8PDehM3i-vv4

My truck has been in the body shop (again) for nearly three weeks now; was sideswiped by a dipshit that made a left turn from a straight lane. Anyway, my buddy owns the shop and offered to install a goodie or two while its there. So.... putting on a Borla Atak today. Hoping to get it back tomorrow or Friday. Then I'll put in the factory cold air intake. My wife is, umm, not pleased I'm getting this - but I really want that classic American V8 rumble. Anyone put an Atak on? How loud is it? I do leave for my office quite early in the morning - hope the neighbors aren't upset.

I had the newest update for a few weeks now. No issues since then.

I'm sorry man. Happened to me at 6k miles. I was without my truck for nearly 4 weeks while they did an engine replacement.

Thanks, but I just got sick of the corporate double speak and run around from GM. I was a reporter once upon a time; had a strong sense this would be of interest to a reporter so I contacted the paper right in GM's back yard. Turned over service records, the TSBs, etc. It's a shame they wouldn't do the right thing until they were called on their BS, but I wasn't going to sit quietly while they used my family as test subjects for their faulty software.

That's me with my Denali in the picture....

I was interviewed for a story on this, coming out in the next day or so. GM is supposedly going to issue a new recall for all the 2019 to correct this. In the meantime we're all R&D dummies for GM.
