So the Dealer looked at it last Wednesday and said it was the battery... The #6 Cell was bad... I was kinda a happy with that answer... So I picked one up on the way Home and Man, they aren't cheap, $175 after getting $15 core charge back... I installed on Friday and so far so good... None of my 6 symptoms have occurred yet...

Having the exact same issues..... Did the G218 clean up bit..... Battery tested at an Auto Parts store said the battery was good.  Curious if your symptoms have come back.

You're welcome on the post. Believe me I was pissed when my truck did this. I love the truck to much to get rid of it and I love electronics and troubleshooting things. So glad my video and posts are

Extremely happy to say that they have not returned.. I also had an auto parts store test it and said it's fine. The dealer tested it for a fee and said it was bad.. I am convinced its your battery..

 

Good Luck and keep us posted..

Ok I just did this last night. I figured it couldn’t hurt. The rubber sound proofing was definitely clamped under the grounding cable washer. No issues this am, however, my issues with the dimming/flickering lights, and temporary loss of power steering when turning at a slow pace were pretty intermittent. My truck even shut completely off a few times when turning into a parking spot or a drive, I had to turn the key to restart. So hopefully this will help. This seemed like the same thing that happened back in late 2017 when GM issued the TSA Recall 17V-414. My dealer fixed it and I was good until about 2 months ago when it would intermittency do this again. I wouldn’t recommend taking it to your dealer unless you can have them climb in the truck with you when it is happening, otheriwise you’ll pay $117 for them to say that dimming/flickering lights are normal, bs. Their service manager must be busy because he was supposed to call me back 11 days ago regarding my concerns for safety. 

One other thing, I think everyone here has downplayed how difficult it is to reach/manipulate that bold and cut the soundproofing. If you have large hands it will be challenging

So this did not fix my issue. Drove it for a few weeks and the problems persisted, most notably a brief loss of power steering and all gauges when turn signal or brakes were initiated. Fortunately I wasn’t needing to make turns, just traveling straight at 75mph with my wife and child in the truck. When I got to my destination, I wiggled the battery cables, they did not budge, but when I restarted the truck to head home all the issues were gone. At home I cleaned all the battery connections thoroughly, although they were already clean and nuts were all tight. Have had no issues now for approx 3 weeks, not even the dimming lights. I’m skepical that this was my entire issue but time will tell. FYI, battery is only 1 year old

After washing my truck thoroughly 2 weeks ago, all these issues popped up on my 2017 silverado 1500 WT, 4X4 Crew cab. At first, it was intermittent and usually on a rough patch of highway. But the last week it was steady. I finally got to my service appointment 2 days ago. There were several communication errors between a bunch of sensors. My truck has 49000 miles, and was told none of it would be covered under warranty(complete and extended warranties were purchased). So i took it home and tried all these fixes,(I assume i still have a lot of wiring yet to check), but the issues are still there. Service stabiltrak, service trailer brake system, no cruise control, no TPMS, ABS light on, hit a bump and the power steering "grabs" for a split second. The only one of these fixes I didn't try yet was battery to ground cable replacement. Beginning tonight I will be tracing wires and ground points, so we shall see. I just wanted to share so maybe, someone watching these forums who may be taking note, realizes how far this problem goes. One of my coworkers had a couple sensor issues on his 2018 Chev 1500 LTZ he purchased in Nov/18 with only 3800 miles on it, but disappeared a couple days later and hasn't returned. It doesn't help that the 2 local GM dealerships in the area are not very helpful. ( whole slew of different stories on that topic lol)

Well sign me up. On the jobsite today, I pulled up to a storm pond the crew was working on, shut the engine off and spent about 5-6 minutes there. When I returned, truck started but no marker around the PRNDL. Then received a Stabiltrak warning and "drive at reduced speed". CEL also illuminated. Shut off and restarted. Gear marker returned but truck now in limp mode. Drove a short distance and shut down. Restarted and only CEL illuminated. Drove to another site a short distance away with truck still in limp mode.. Parked and completed what I came to originally do. Took about 30 minutes. Restarted and everything is clear, truck in normal mode. Code reader showing 0700 and 0073 codes. Plan to remove codes and see what's next. I did install a catch can last Saturday but I'm guessing I have a ground problem too.

All, 

I am experiencing all of these issues. One thing I’m experiencing along with the stabilitrak, the flickering lights and the cruise being kicked off with the turn signal is that my radio will flash on and off occasionally when I press the brake and some times when I use the turn signals as well. 

 

Initially I got the dampening material out from the ground and it stopped for a while. 

 

Then I scrubbed some of the paint off the ground and put a star washer on the ground as well as run an additional ground from g218 to the center ground behind the light sensor. 

 

The guy at advanced said my battery was fine and that it was pushing over 900 amps. 

 

These issues have have persisted all of these failed fixes. 

 

Would anyone have any idea what I could do next to fix this issue? 

 

I don’t want to have come to the part of trading in the truck, so I would like to fix it 

 

Any help would be appreciated. 

 

Thanks

Tjbrande, I had those issues you have and the under dash grounding fix didn’t work for me. 

Try disconnecting and brushing all the battery connections with a wire brush or terminal cleaner. My connections all looked fine but I disconnected all the wires connected to the battery and cleaned them anyway, haven’t had any issues since.

 Thanks man I will try that. I’m guessing you just used a battery brush for the terminals and cables? Also did you unscrew and clean the distribution box as well?

 

Thanks

I can’t get my hand in the tight space to even remove the tweeter, much less get to the ground. I see it, but can’t get to it. Guess I’ll just live with it. I’ll try the battery and see if it’s bad.

      Lower trims ( WT, Custom, Silverado ( aka LT )

      By newdude · Posted

      HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.

      2021 vs 2026 handling (1500 X31 Sierra)

      By dennismc · Posted

      I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it.

      frustrating P0446 code

      By Old Bay · Posted

      So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.
