    odd stumble when accelerating

    I'll try tow mode and see if that makes a difference. I disconnected the battery the other day to "reset" things. Seems to have made it worse. It was actually shifting bad in all gears for the first few miles I drove it after that. Now it's back to just doing the 2nd gear stumble, but it's...

    odd stumble when accelerating

    Thanks for the responses so far. I did clean the throttle body and the MAF, forgot to mention that. They were both very clean, but I hit them anyway while I was in there doing the seafoam. I was assuming it wasn't a software issue as it only seems to do it when it's cold. Once it warms up it...

    odd stumble when accelerating

    I've owned my 2015 Yukon for about a month now and after about 1200 miles I've had a nagging issue with it that I'm hoping to get some suggestions with before I start replacing stuff. This only happens in the morning on my first drive with it and only happens under certain throttle positions...

    Holy Squat! Yukon XL Towing

    It seemed to handle the weight fine, I'm just not used to my vehicle being so sensitive to tongue weight. I ordered the helper bags. I'll get those installed and report back. I plan to keep this Yukon for 4-5 years at least so I want to treat it right. Thank you for all the responses.

    Holy Squat! Yukon XL Towing

    Yes, I was surprised at how high the hitch is on this and did not bring my 6" drop bar with me. This was a 4" drop. I'll be using my 6" from now on with this Yukon.

    Here's the factory spec sheet on it. Not sure how to tell what suspension, it's not air I know that much. Truck has 54k miles on it.

    Holy Squat! Yukon XL Towing

    I do understand that the weight on the trailer was more forward than desired. The question I'm asking is about air bags and if they will help reduce squat, not if my trailer was set up properly. I did not have a choice on where to put the tractor as there was a 4' brush hog behind it which was...

    Holy Squat! Yukon XL Towing

    It's a 2015 Yukon XL slt without the factory tow package as already stated. There's only 1 engine/trans option and without the tow package there's only 1 rear end so I'm not sure what additional information you are needing here...

    Holy Squat! Yukon XL Towing

    Weight was a little forward on the trailer because I had a brush hog behind the tractor, but it was so little weight that it shouldn't matter too much. Tractor and loader only weight about 2500lbs mower deck and brush hog probably another 450. I'm used to my Titan XD that I traded in that was...

    Holy Squat! Yukon XL Towing

    So, My new to me Yukon XL did it's first bit of towing last night. Did a 5hr round trip to pick up a Kubota tractor. total weight behind me was only about 4,000lbs. Man, this thing squats! Other than that, it towed great, I could barely tell there was anything behind me, but I'm looking to see...

    New Yukon XL owner (soon to be)

    My local GMC dealer here fixed it yesterday for me. $168 bill for that and I had them do an oil change while it was there too. Just sent the bill over to the selling dealer, waiting to see what they say. I do have it in writing.

    New Yukon XL owner (soon to be)

    Here's a few pictures. Picked it up yesterday and drove it 180 miles home for the first trip with it. It runs and drives great, seems to have no issues other than the sunroof weather stripping on 1 side was hanging off. They told me to get it fixed locally and they'll pay the bill. Super...

    New Yukon XL owner (soon to be)

    I was able to get most of the service history on the vehicle from the 4 different dealers / shops it's been at over the years. The rear AC lines were replaced and the rear ac had a "service kit" done to it. I'm assuming it was leaking as it was recharged twice before that repair was done. Then...

    New Yukon XL owner (soon to be)

    It does have the 3.08 gearing which is the only thing I'm a bit disappointed with. My truck now is rated for 12,800lbs towing although I never towed more than about 6500 with it, it was nice to know I could tow pretty much whatever I wanted. The build date on this one is 12/22/2014. I did just...

    no more lease sales to Carvana or anyone other than GM

    I did this with my Ram 1500 last fall. I had to "buy" the truck from FCA and then immediately sold it to the dealership. The wrote me a check for the value over the lease and I walked away. I was only halfway through and still cleared a few grand.

    New Yukon XL owner (soon to be)

    Hello I just put a deposit down on a 2015 Yukon XL SLT. It has 54,350 miles on it. 4x4 with the open road package. I haven't actually seen it yet as it is about 3hrs away from me at a dealer in Tampa Fl. I was planning on ordering a '21 diesel Suburban, but I was told it would be a 6 month wait...
