Would the battery issue show up as a voltage drop if and when the problem occurred? I can tell, audibly, that there was no decrease in voltage from starter sound as well as light brightness.

I would do a wiggle test. Open the hood in the garage and start wiggling/tugging on connectors and wiring harness and see if you can recreate the issue. Maybe try under the dash as well. 15 min could save you some aggravation.

Check the ground cable located behind engine on drivers side that is attached to firewall. There have been issues with that in the past from other posts I have read.

I picked the Yukon back up not all that long ago.

As per the paperwork, the dealership did the following: "Test drove, pulled codes- - all history. Cleaned battery cables, fuse block per #18NA161. Could not duplicate concern at this time."

I searched this TSB, and it is described as "#18-NA-161 - Steering Jerks Or Kicks Back / Reduced Power Steering Assist / Engine Stall / No Start / Service Stabilitrak / IPC / Radio / HVAC Goes Blank Various DTCs - (Oct 22, 2018)"

Apparently it affects all of these 2014-2019 models, including the GMC Yukon, GMC Sierra, Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, and Chevrolet Suburban.

I have read plenty and have seen plenty of videos of the jerking steering wheel, which has never happened to me. With the exception of the one 2018 Sierra owner, I have not heard anyone else complaining about having neutral in all gears, either. I can't say if this will do anything or not as they said they didn't find any corrosion or anything out of order on any of the connections. It would also be interesting to know if they checked that grounding stud on the dashboard. I assume if they go through a TSB they would do everything it suggests? Who knows, I wasn't there nor did I do the work.

One odd thing I noticed that I had not before, I was stopped and first in line at a red light, and the cross traffic was tripping my front parking sensors. Every time a car would drive by I would get the front parking sensors detecting their movement. This seem to only happen one time, shortly after I left the dealership. Do these sensors need to re-calibrate themselves after a disconnected battery by chance? I have never noticed it doing this any time in the past.

This might only apply to 2003-2007 trucks but I had the same issue a few years back on 03 Silverado.

I went under the hood to the fuse panel and pulled out the fuse/relay that says SEOB1. And or SEO IGN. After pulling them out for a few minutes and putting them back in all was good afterwards. It has never happened again.

This suggestion came directly from an Engineer @ GM, my brother.

That's strange. I really didn't do any digging around that evening other than wiggling the battery cables. It was cold, dark, and of course all of my tools are in my garage where they belong, not sitting in the back of a one year old vehicle. I'll have to remember that for next time.

2017 Yukon Denali here. My battery lost a cell at 18 months and around 10k miles. While it BARELY started, it never threw a code or had electrical gremlins related to that issue. I live in So Cal, and there isn’t one bit of rust or corrosion on this SUV. The only gremlin I have now is the fuel gauge no longer reads full even though I topped off the tank.

Just a data point.

Something else I noticed today while running errands was a strange start. The truck was fully warm after running errands, and I had made another brief stop for about 15 minutes. Came back in and started, and it didn't just fire up. It's difficult to describe but it was almost as if the starter was cutting out. The cranking time was definitely not extended. After this I immediately drove to the nearest O'Reilly Auto parts to have the battery tested.

While the battery was connected to their tester, I fired it up, and it did the exact same thing. The O'Reilly staff member said they heard it clear as day, but did say that the battery, alternator, and starter all checked out. They did feel my voltage was somewhat high though, they said it was almost 15 volts which is higher than what they usually see.

Any thoughts? I know there was a TSB for 2015-2020 models about extended crank times, but I feel that this is different, as I did not experience any extended cranking times where the starter is continually running without firing up.

How repeatable is this new phenomenon?
