I started having issues that seem to be related to a grounding problem. I cleaned and secured the ground located on the frame behind the front passenger tire and the ground under the dash on the driver side that seems to be referred to as G218. I inspected the ground under the dash on the passenger side and it was clean and did not seem to have any noticeable problem. I was hoping someone could point me to other ground locations I should inspect or possibly anything else I should look at.

 

Here are the issues I have had in order over the past 2 weeks.

1. I noticed the occasional reset happening and started having some slow starts.  it was time to replace the battery and I noticed the battery caps had pushed up some so I replaced it with another AGM battery.

2 drove about 20 miles got out for about 15 min then drove another 10 miles I went to start the truck no lights no starter no anything. I pulled the key out and tried again the dash lights flickered I cussed tried a third time it started up just fine drove home about 30 min.

3 I cleaned the 2 known problem ground screws went for a 10 minute drive everything worked as expected

4 Drove about 30 minutes stopped for an hour then went for gas everything still working as expected. After getting gas I drove about 5 miles and started into a parking spot and the wheel jerked out of my hand. If i turned right or left the dash lights would flicker the wheel would jerk and things showed signs of a battery disconnect IE clock reset stabil trak popping up but the truck never died. I sat idling for about 10 min and the wheel would jerk when trying to turn. I decided to turn it off and restart the truck. It started as expected and all the issues cleared up enough for me to drive it home about 30 min. once home i started the truck 3 times with no noticeable problem.

I have no mil light coming on but it is asking me to roll the windows up and down like it does when things have been reset

 

Sorry its so long i try to provide as much as i can

2014 GMC Sierra 140k mostly kept in garage and driver a couple of times a week.

 

TIA

I tried posting a link to a video on YouTube but it keeps getting blocked. So check out South Main Auto on you tube he has a lot of good videos on Silverado grounding issues.

OEM ground cable seems to have resolved the problem I will know for sure in a day or two.

They are on back order almost everywhere I would stay away from the knockoffs.  I had an oem and knockoff on order the china version was poorly made.

 

Thanks for the responses

Almost exact symptoms for me as well!!! I have a supposedly ‘exact GM replacement’ on the way from RockAuto. Complete negative cable with current sensor. Other GM original options available but folks on here recommend GM instead of cheaper knockoffs and so far the ideas/suggestions here have been pretty much dead on! My replacement is scheduled for delivery tomorrow. Guess I’ll see ..

 

Kudos to all that help with these concerns. Very appreciative!

 

Thanks!

      No Software Updates - Old Build

      By DaleB · Posted

      Hi all - my current truck is a 2022.5 1500 High Country 3.0. I bought the truck used last year. After doing some digging, I noticed that my truck's software is stuck on the original build from 2022. I have no available software updates. I talked to my dealer about this and they recommended not trying to force an update since the 36,000 mile warranty is expired. This is a big bummer since there have been many major releases since that have fixed small issues and improved speed/usability.   For reference, the current software build number is: full_gminfo37_gb-user 10 W158E-W164.4.2-QIH22B-563.3 158 release-keys Has anyone had a similar experience? Should I just forget about it and move on, or try a different dealer?

      Using zip ties but 2-3 they snap due to sharp edges. Just using a shoestring. Last longer. 🤣

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I ordered the Snap On...waiting for it to come in later this week or early next week.   New front cover, new crank seal and new balancer are on. Water pump, pulley, fan, hoses, and plastics reinstalled. I can move forward knowing all my timing marks are dead on and the front engine is hopefully sealed better than it was. Take 2 with the water pump...trying high temp thread sealer on the lower bolts.   Rebuilt injector and new-new regulator is in, it looks like new. Top intake reassembled and all the bits are reconnected and snugged down.   Thinking about knock sensors again, I located both of mine and, there's your problem, Francis... The driver's side one is broke, plastic is bashed in, part of the wire is bare, and it appears to have been damaged like that for a long time. I saw the wire but didn't think anything of it. The knock sensor might not be my pulled timing issue, but it sure looks suspect. It must still be conducting, otherwise I'd expect a CEL. But perhaps with its sacred crystal inside exposed, jilted and dirty, maybe it's sending mixed signals. So I'm waiting for one of those and a new pigtail to come in. Pass side sensor looks good, except for the spark plug wire resting on it (!). The plug wires are healthy so it shouldn't be causing an issue, but I separated them and added zip ties to nearby looms to keep everything well apart.   So, I'm down to installing a knock sensor AND, oh, replacing the exhaust and cat. I actually think that's going to be fairly easy, it's all bolt-together, all new stuff from Walker is laid out on the shop floor ready to go. Hopefully have this thing on the road again for the weekend.   My luck? It will still be leaking oil, coolant, pulled timing, intermittent CEL for running rich, or it probably won't run at all -- because that's how this project has gone.   I've never worked on a vehicle so ...hurt? ...cursed? in my life. Everything has been effed with SO HARD, but I think...knock on wood...I've managed to undo all the backyard stuff and we're almost reset back to "just" an 80k mile, 30 year old Blazer.

      Would this CV Shaft be bad?

      By PunchT37 · Posted

      Yes. You need to check out that thing, and the hub further.
