I had this problem on my 2016 Sierra, someone said to Google G218. I did. I cleaned the dash grounds and replaced the negative cable off the battery. I also took a grinder and totally cleaned where the cable connects in the passenger wheel well and then sprayed it with undercoating. My truck hasn't shut off since.

Welcome to the site.   Maybe start here?   It was the G218 (I think) that had material pinched between nut and framing, half the contact point was covered. This and a loose negativ

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.

That one really sounds like the ground at the base of the windshield under the dash trim.  There is a sound matting that can be pinched by the ground wire terminals and it will cause poor contact.  Th

My truck is "shutting off" while driving! It is typically at low speeds while making a turn or putting car back in gear from a stop. The power steering locks up & I loose all power. This is extremely dangerous, I have read several other reports of this happening. A stabilitrak message appears, then says to lower driver side window upon restart. The radio is reset to like 87.7 (the default station), as if you had dis/reconnected the battery.

Did anyone find a solution to this? I’m experiencing this exact issue.

I’ve had this issue as well, except mine almost killed me! I just replaced the alternator and battery about 2 months ago and out of the blue it dies mid drive on the highway during rush hour going 75 mph. Lost all power and no power steering and almost crashed head on into a guard rail. The battery and alternator are brand new and this will be the third brand new battery I have put in it so there has to be another underlying issue that I am not seeing, if anyone has any insight on this please let me know. I have always been a Chevy guy but I also had this same issue with my 2011 Camaro. Chevy is t doing me justice right now

What a great forum!  My 2018 Sierra Denali has been experiencing these issues for some time, but it's been so intermittent I've been afraid if I take it in, they won't find anything and look at me like I'm some crazy lady LOL   I lost the steering twice the other night, fortunately while going slow, AND the truck totally shut down (vs shut off) as I pulled into a parking space.  She's going in Wed and I'm going to mention this G218 and the negative battery cable for them to look at.  It's still under warranty, so crossing everything that fixes it!

There's a TSB on this also, but my dealership was too lazy. My truck is still running great since I did the repairs. Basically the ground cable was the culprit.

I was under the impression that this mostly affected 2014-15 and was pretty much a non issue on later models. The negative battery cable is definitely something to get checked though. There is also a main ground on passenger side rear of the front wheel well. It has been found that it is sometimes not cleaned properly from where frame was coated before ground is attached and this causes a poor ground. It can be removed and mounting spot cleaned and scuffed as well as connector on ground wire. Reattach and then just have coating applied over it.

I have a 2017 Silverado LT 4x4 lifted 6” with 35” tires. I had this happen to me back in November of 2023 and after investigating it pointed me to my throttle body. I replaced with a GM OEM and everything worked fine. Recently I’ve had the same issues( truck shutting down, steering wheel locking up, the stabilitrac message as well as a power steering message that says drive with care). After more research, everything is talking about the power steering assist motor/module located on the racket pinion. I’m gonna look into the faulty grounds but very close to taking it to the dealer??

I’ve checked my ECM for codes and it says I have no codes. At this point, I’m a little concerned about driving it

I'll think the main issue was the ground cable, I bought a new one and installed it. I read somewhere it could be an issue.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
