Low Battery, Engine wouldn't turn over, DIC goes crazy, is this normal?
Purchased used 2021 Yukon Denali w/6.2L last Aug and I've know it pulls down the battery but... after 5 days of sitting the battery was only at ~11.2v according to my battery monitor. Tried to start the car and engine didn't turn, brake pedal pushed back at me, and DIC went crazy with things...- tagexpcom

2021 Yukon 6.2L not driven much - how often does it need to be driven for good health?
We recently bought a used 2021 Yukon Denali w/6.2L for towing our camper. I have a battery tender on it as it can be 4 or 8 or 12 weeks sitting in the garage between camping trips. Question: How often (beside battery charging) does a vehicle need to be 'exercised' to keep oil / internals...- tagexpcom

2021 Yukon Denali - 4wd-hi - bit noisy/awkward at 1mph, sharp steering
Bought a used 2021 Yukon Denali last summer. Went winter camping this week and had my 1st experience with 4wd-hi in the snow. Did a little driving around on unplowed roads with 3-5" of snow, just a little slippery/bumpy from previous snows. When turning around, at <2mph, turn sharply, backup...- tagexpcom

2021 Yukon Denali - 250w pull is causing 120v outlet to shut-off
My 2021 Yukon Denali has 2 x 120v outlets - that are marked as 400w. However, when I reach 250w-300w range they cut-out. Unplug and replug and they re-activate but again cut-out at 250w-300w range. Does anyone have detailed power ratings for these or how they work? Is the 400w split...- tagexpcom

Highway says 5% grade, 2021 Yukon Instruments say 2-3degrees
We recently purchased a used 2021 Yukon Denali and one of the features is the 'level' of the vehicle. We live among the mountains - so anyplace we go to escape town requires going over a 5% or 6% grade as posted on the various highways out of town. However, I've noticed that the rig's 'level...- tagexpcom

2021 Yukon Denali - Battery alarm is LOUD - what makes it stop?
Recently installed a new battery and then a few weeks later a bluetooth battery monitor. Both times this EAR-SPLITTING alarm goes off when the battery terminal is disconnected....

2021 Yukon Denali - Correction, the "40w pulling the battery down" was misread of clamp meter
***I apologize for posting a completely wrong battery draw reading*** It's actually 2-3w. I recently bought a used 2021 Yukon Denali with middle package. I drive once a week. Noticed the battery seemed really low and started measuring it at 12.0v - 12.1v. Thought it was weak (used car...- tagexpcom

Mirror Cracked - 2021 Yukon Denali
Just purchased a used 2021 Yukon Denali and on it's 1st trip to the auto-shop the RH (Passenger) Mirror was loose on pickup. Still worked but would wiggle up/down about 1". I suspect the shop did it somehow but maybe it was that way when I took it in?? The shop are nice folks and it just... -
FORD Dealer says "Waiting on Previous Owner/Lender" - 2021 GMC Yukon Denali
We paid for a used 2021 GMC Yukon Denali 6.2L at a Ford dealership. Part of the reason for going this way was to avoid title hassles and have the nightmare of a car that can't be titled! It's been 3 weeks since purchase and now I have a letter from the dealer saying they are waiting on the...- tagexpcom

SD Card Removed - and I did it! (Yikes)
We're test driving a used 2021 Yukon Denali this week. All is going well, price OK, beautiful car, towing test was a success, everything works so we're likely to buy. However, poking around I ran across the SD Card in the center console and popped it out, put it back in wondering what it was...- tagexpcom

Towing up Mountain Pass - 210F Engine and 199F Transmission
I'm in the process of buying a used 2021 Yukon Denali 6.2L. A key thing for us is towing a 5,300lb 7 x 14 cargo trailer converted to a camper. In Southern Oregon we can't go anywhere without going over 4300 - 5200ft mountain passes and our old car overheats at 70F ambient or hotter. Did a...- tagexpcom

Front Mount Hitch (2" receiver) for 2021 Yukon Denali?
In my previous vehicle I use the front hitch to push my trailer into a tight parking spot along side the house and I have a receiver oriented winch + portable battery so I can winch front or back. I am hoping to continue this capability by adding a front receiver to my 2021 Yukon Denali (6.2L)...
