Hi people, new to the forums. I have a 2016 Silverado crewcab 4x4 z71 with 17k miles. Over the last few months my truck has been "jerking" or feeling like a hard slam when coming to a slow stop or after I hit the gas pedal. I'm scheduling an appointment to get checked out, but looking for input on possible cause or better way to describe it. Additionally, I've noticed the truck idling really rough lately. My kid even said "why is he truck shaking". It's not like this always, but becoming more frequent.

 

Appreciate any info. Thanks!

New software release see for the 2017's. Did a bunch of them today. Stop in the dealer and see if yours is updated.

 

This applies to the MYC 6 speed by the way

I had the same thing happen with the rough idling with my truck for about a week at around 18,000 miles... everything is fine now. As for the jerk at stop and go my truck does that as well, I've read that this is the normal operating conditions on these transmissions unfortunately

My 2017 Yukon Denali suffered from random "missing" - car would run rough, jerk and chug at idle and only sometimes throw a CEL. Dealer had it for 2 days, couldn't duplicate and no saved codes. Happened again yesterday on the highway, flashing CEL and was able to get OnStar to run a diagnostic while heading for the dealer - OnStar said P0300. Light was still on when I pulled into dealer. They determined bad injector and are replacing - we'll see if this fixes it. When it would start to miss it felt as if car was driving over those rumble strips you occasionally see on the highways.

Thanks for the quick responses. I'll ask the to check software and see if they're seeing anything like this locally. Sucks to buy an expensive truck to have issues.

Went to one dealership and was told that it's normal in newer chevys due to air compression. I was also told it has like 32 computers on board so the idling is normal unless the check engine comes on. I went to another dealership and hey said it has some wiggle room, but I shouldn't feel a significant jerk. Now I have to figure out how to make sure it happens when they test drive lol.

Wait, what?!?!

 

I have been following this issue for a while now and saw the latest notice on TechLink. But even that one says it only applies to the 8-speed.

 

Great to hear it works on the 5.3L / 6-speed. I'll be asking my dealer about this!!

Supposedly fuel injector cleaner will fix the rough idle (brother was complaining about it, said that cleared it up) You would think a new truck would have clean injectors though

Mine had been doing this, 2016 silverado 5.3 z71, put fuel injector cleaner as well and it cleared it up some. Idles smoother now. Have 24k miles.

I did BG fuel cleaner today, so we will see if they helps out some. Otherwise, the jerking feeling when coming to a stop we couldn't replicate at the dealer. I'll keep an eye on it.

      Needing this part.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
