I have a set off a 2014 - white caps - live in MI too

Mine did it once - after several no starts I tracked it down to the "known" negative battery cable crimp (2014 Sierra) - replaced a year ago, no repeats to date.

Received my notice in the mail yesterday - it states "failure to follow recommended oil change intervals could contribute to this condition." I can already hear the excuses for a sub-par part failure being blamed on oil change recommendations between manufacturer (oil) and DIC.......Too - I do not have the DTC set as of yet however, the condition is present. I have some time before this "fix" runs out - so I will let the garage monkeys figure out the technique before I get in line to change out mine

My '14 had bad corrosion in the sockets - $41 @ Rockauto for a new wire harness - problem solved....

I have read lots of these things failing on this site, here is what I found: Harness needs to be replaced - ordered from rock-auto - anyone else see such corrosion inside 5 years? I could not believe the dirt that is thrown at these bulbs, once I removed tail light assembly. This will become a yearly service - remove, clean and reapply dielectric! 34K Miles - right side blinker indicator "malfunction comes" on - simple, replace bulb (top bulb), lasts a week. Second try, scrub clean with electric cleaner and use good dialectical, install new bulb. Now the lower bulb goes out, same thing - all rusted up, this time cleaning and new bulb do not work. Top and bottom bulbs have rusted the terminals away inside the sockets. Just sharing my findings

2014 - did the same thing. Put a new negative cable on, no issues for 9 months now. Bad crimps in some harnesses, some battery posts are smaller in diameter, so clamp wont tighten down......give that a try next

Drilled and slotted on the bosses Acadia - LOTS more brake noise - I would not put these on my truck. I went with best from Rock Auto, so far great after a year

Went thru the same issues back in the spring - replaced the negative battery cable......bad crimps in many of OEM's installed at factory. Fixed the issue, no problems since

Used the lithium ion schumacher several times now on a couple vehicles including mine (2014 battery vs. neg cable fight).....holds a charge for a long time and fits under the rear seats. under $100 at super store here in Michigan

Try resetting the ECM - disconnect the neg cable for a couple minutes. Might blank out a fault this is prohibiting the start

Similar issue - changed out negative cable (bad OEM crimps)......working fine for a couple of months now. New battery at first did not solve issue. Too, I hear of park/gear selector switch at tranny being an issue as well.

Update - day 10 after replacing negative battery cable and things are still good

Several similar issues posted here - Mine died about 3 weeks ago: new battery did not solve issue, new negative battery cable and things are good 10 days into it. lots of 2014's experiencing this: new cables fixed many a recent one was the park/neutral switch.....keep posting issues and soiutions

You dropped the pan or a heat shield? FYI - my fix so far is a new negative cable (1 week trouble free but I wince every time I turn the key to start position). I can state that P/N: 84319729 is not a direct replacement like GMParts stated. This cable is about 1 foot longer then the original P/N: 23138970 at the engine side.
