    40,000 Mile Report

    Any idea how much it costs to do the second bank? I'm 99% sure I'd just have paid to do it and try to get the money back later. One of the stupidest policies ever. I hope they changed it because they were getting hammered in public opinion. Right now, I'm planning to do TSB 22-NA-027 on my own...

    What can be done?

    Being fortunate enough to work remote, I would go camp out at an open table in the sales department every day until I had a vehicle.

    1000 miles from home dead 2022 Denali

    The dealer I purchased from wouldn't give me the regional manager's number. Customer care still hasn't forwarded my request. Going to a new dealer this week.

    1000 miles from home dead 2022 Denali

    It's a Duramax. ;) And I will definitely be asking for them to pick up my 7/70 warranty cost.

    1000 miles from home dead 2022 Denali

    We were on a cross country RV trip and the dealer had a week to figure out we had the misrouted harness around the alternator before we needed to move on to the next town. They rented us a one way Uhaul to tow our trailer. The cab was too small for two of us and our two dogs, so they flew my...

    Beware: GM Nightmare - Defective 2024 and 2022 Yukon Diesel

    This. No way would I have taken the 2024 to the same dealer as the 2022. If there was only one dealer in town, I would have taken the money. Our dealer is rated pretty highly, but it appears I will need to change, as they aren't willing or interested to get to the true root of the issues...

    2023 Tahoe Premier towing issues, no air ride

    Get an Equalizer hitch. We tow a 7500# GVWR high profile tandem axle travel trailer and it sags like crazy, even with the Equalizer, with no way to add helper springs/bags (shame on you, GM), but it tows like a dream. We traveled through an atmosheric river in Cali, with road signs advocating...

    Yukon water torture

    Yeah, I'm done buying new. Dealers have their hands tied trying to debug known issues or just aren't good looking for TSBs. I have two known issues with TSBs, so I'm now engaging corporate to try to get dealer to resolve. We are quickly closing in on lemon law out of service limits, which is...

    2021 Suburban LM2 reliability sob story

    Yeah Yeah, found that. Dealer said they didn't find a leak. When I asked if they used the defined process, they said the error code that indicated the need for the test wasn't present, so no. When I asked if I needed to contact corporate, they said "if it is a concern for you". Yeah, it's a...

    2021 Suburban LM2 reliability sob story

    Do you know if there is a TSB on this? My dealer doesn't seem very interested in finding the source of the diesel smell in the cabin of our Tahoe RST (what idiot designed the exhaust to exit underneath the truck?!).

    Need suggestions - After the mess I have gone through over the past 9 months, what should I ask GMC to do? Vehicle repurchased, new vehicle in shop

    Did you check the carfax? I wouldn't be surprised if the engine or lifters were replaced and owner got it replaced. If repaired properly, shouldnt be any issue, but it's really hard to get over that experience. I wouldn't risk it, if it has been out of service a long time, even though I know a...

    Here's a new one - transmission

    Sure, but I had downhill sections and it would not shift up. There was definitely something off in the transmission control.

    Here's a new one - transmission

    Always use tow/haul, mostly use cruise, watching EGT. Today running about 13 MPG, well above average. ‍♂️

    Here's a new one - transmission

    Hadn't even gotten to the mountains. Was wondering about wind, but like i say 10-20 miles later, comparable conditions, and it started allowing higher gears. Same through mountains on the easy bits, but it did hold lower gears in going downhill. Was in tow mode the whole time. Also, been towing...

    Here's a new one - transmission

    Started out from Bodega Bay with the travel trailer this morning and looped around to I-80 and north toward Oregon and stopped early in Orland for fuel after about 180 miles. Fuel mileage was terrible, like 8 MPG. Continued heading north and realized I had never seen the gear indicator on my...

    Knocking, check engine light, emission and speed warning after NEW crankshaft sensor installed

    Oof, that's an invasive repair. I would go over the harness in detail first. They could get the harness, get everything exposed, but not removed, then really inspect everything. I'd much rather have a patch, than count on everything getting routed correctly. The assembly people struggle enough...

    21+ IRS SAG issues when towing product design (looking for someone in Michigan)

    Met a guy with a Silverado and he swore there was an extended bump stop solution for the SUVs, but no, I didn't find it.

    Knocking, check engine light, emission and speed warning after NEW crankshaft sensor installed

    To be a little more helpful (but not much :p), someone mentioned a TSB in particular for chaffing at the alternator bracket, due to improper routing. I had a litany of crazy errors.

    21+ IRS SAG issues when towing product design (looking for someone in Michigan)

    My thought is the damping needs shouldn't increase. The shocks should already be adequate for the increased load, and the spring reduces the amount of travel. I suppose you could get unlucky and end up with a weird harmonic, but otherwise should be fine.

    21+ IRS SAG issues when towing product design (looking for someone in Michigan)

    I think part of the front lifting is caused by the rear squatting, so it should help. But that's kind of the whole challenge, no one knows. Someone has to do it, since none of the air shock guys are committing to even investigating the solution. :confused:

    First Towing Experience 2021 Yukon Denali - 5300lb trailer, with and without stablizer

    Sorry to bring this back from the dead, but I’m techy. Did you have water in the tanks to begin with? If not, you could have added water to see if it eventually settles down. But at about 80 pounds of propane (or perhaps 80 pounds of generator, as someone brought up), I would start by moving...

    Yeah, barring a ringing endorsement, I'll probably try the coil Sumo spring first.
