Be sure you can leave the vehicle while the entire download happens....dont turn off or on unless instructed. As above, it will eventually force you...better to choose on your time where you can wait for it...also park outside so no issues with interference.
Thinking seriously of going back to XL from current 2021 AT4 Yukon (always drove the longer model since mid 90s)? Anyone have good info on when 2022 production is scheduled to start?
Rolled over 17,000 miles this past road trip. AT4 continues to roll on with only a few minor (corrected) issues. From previous posts there were the too short pigtail wire and a couple of issues fixed with software updates. Beyond that, nothing....not even a rattle. Am always hesitant to buy first year new design but it has been rock steady. Gas mileage is finally back to where my 2017 Denali XL with the 6.2 was. Last highway trip (cruising in the 75 to 85 range) was over 18 mpg. The 5.3 with the new transmission is responsive and more that up to the task
UPDATE TWO - I let the update run and when done, battery was dead. Used OnStar for service call to jump and then took to dealer to check. On the way vehicle was throwing every error message including "Service Steering Column". Dealer fully charged and checked battery and reset to factory settings. When I put in park at home, the update message came on again (see below). So I let it run. Checked back in an hour and there was a sucessful update message (see below). Vehicle started right up no issues so all good. >>>>>>>>>>>>>>>>
Rolled over 7,500 miles on my 2021 AT4 Yukon. Have driven Suburbans/Denali XLs for years. This is my first Yukon/Tahoe model. Issues are none. To date, a reset of the TPI and the too short pigtail wire under the driver's seat have been the only issues. Impressive for new model. Finally use to the push button transmission. Still not a fan but don't have to think about now. It took this long to adapt. Gas mileage continues to climb but still not equal too or better than my 6.2L 2017 Denali XL. A couple of suggestions for the GM folks on how
You are entirely correct on turning off the "Exit Mode" in the settings....I have never been one to read Owner's Manuals and am old enough not to be able to figure out this new fangled technology...THANKS!
Rolled over 5,500 miles this weekend. A couple more observations to my 3,500 review (link below).. 1) Have you noticed the front wheels sit to the rear of the sheet metal arches....looks odd when viewed straight on. Wonder why not more centered. 2) Suggestion to GM...the LED lights on the three seat heater A/C buttons are on the outside of the switches. If the full seat heater is on, it is hard to see the LED lights from a normal seating position. Move them to the inside side of the switches for an easy read. 3) Fuel mileage continues to climb. Did a 526 mile roundtr
Awesome...is is white or silver on the outer lip of the spokes?
I ran Nitto Grapplers (OEM size) on my 2017 Denali XL 4x4 and put nearly 30k miles on them...no visible sign of wear at that point. My use for off road is Texas ranchland so not rock climbing, mud bogging etc. Appear they would be great in snow as well (I grew up in Wisconsin). Tires were exceptional in my off road use. Road noise was surprisingly quiet. I immediately swapped out the OEM POS Goodyear tires on my 2021 AT4. Same size as factory.
I debadged my 2021 Yukon AT4....the AT4 logos on the front doors and the YUKON type on rear tailgate. I like the cleaner look. May still remove the AT4 logo from the tailgate, not sure yet. Easy to do with the old hair dryer, fishing line and 3M spray automotive adhesive remover. Took about an hour total including the clean up and waxing were they were.
