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
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
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

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.
Spendit replied to Spendit's topic in 2014-2018 Silverado & Sierra TroubleshootingUpdate - 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.
Spendit replied to Spendit's topic in 2014-2018 Silverado & Sierra TroubleshootingAnyone have the correct part number for the negative battery cable, as 84319729 sent from GMpartsgiant is not compatible. The engine side terminal is flat/straight on the vehicle and the part sent has a 90° bend. P/N 23138970 that is on vehicle is no longer available, obsolete....maybe they changed the mounting location to accommodate the new P/N - anyone have a manual or experience?
