I am new to the forums and hoping someone may have seen this or run into this before. I own a 2012 Silverado LTZ Crew Cab, 5.3L, 2WD, 102K miles, Factory radio with a harness plug for a an amp for subs. Electric drop down side steps. LED headlights & fogs. K&N Nighthawk Intake. Battery is less than a year old but i'm in Arizona so batteries get wrecked yearly. I recently took my truck to my local DIY car wash place where I always go. I washed my truck like normal and dried it off like normal. I did not spray engine bay, just the front grill area inward but not heavy. I don't usually use my AC but I'm in Arizona and it was about 109* outside. When I was leaving the car wash I kicked my AC on so I wouldn't mess up the clean windows from rolling them down. I proceeded to leave and as I was coming to the stop sign before making my turn and my truck's idle started to drop, truck kinda sputtered, the battery voltage dropped, the stabilitrak light, traction light, ABS light, all kicked on. The radio shutoff and turned back on. The AC shut off and turned back on, but switched from recirc to fresh. I turned the AC off and then back on again and continued to drive home. It did it a few more times so I swung into the gas station to park and see if it would do it while i was sitting there. Nothing. So back on the road again, turned my AC on and hit the next light, and it did it again. I changed my oil today (6/13), I cleaned my K&N air filter last weekend. I took a trip to Lowes this morning to see if it was still doing it, and sure enough it was. The photos are attached of it doing it in the lowes parking lot before I left. I rolled the windows down, turned the AC off and cruised home. It didnt do it again. So I am thinking the AC is drawing a huge amount of power from the system when I run it, or my battery is done for. Any helpful feedback would be appreciated.

Greetings to everyone Recently I have made few fixes in my 2017 GMC Yukon and my fixes was in the car suspension and control arms due to a very strong vibrations in the middle console and after the mechanic was done I asked him to take a look at my lane assistant because it hasn't been working properly for a while so he hooked up his obdII diagnosis and started reprogramming and learning for the steering assist and front camera module (which is located at the windshield behind the mirror) little did we know these issues will appear after he is done, so before the reprogram process I had no lights on the Dash at all, only when I started the vehicle I get (service parking assist) but it wasn't an issue for me, so after he press learn on his device ABS, traction control and stabilitrak lights all went on suddenly like Christmas lights and ever since it didn't go off and he couldn't fix it back even though he tried to do all the learning and programming of the device and his diagnostic said it was successfully learned but the faulty codes kept coming back. I attached the obd diagnostic report and hope anyone could help Also in the report I saw new to me codes like HVAC and radio weird codes even they're working fine 2017 GM Vehicle Diagnostic Report_1GKS17EC5HR103833_2024088181503.pdf

Hey everyone, I have a 2017 Chevy Silverado 1500. I bought it in April of last year and it has been miserable. I visited the dealership more times than i can count and some problems still are happening. The main problem is my truck shutting off. In Early September, I noticed as i was driving my radio would go black, then as i would tap my breaks everything would shut off and turn back on. As this happens, the stabilitrak light comes on, my truck stalls (sometimes) steering wheel locks and starts shaking. Now this happens everyday when i drive it. Go to the dealership they say it is a corroded wire, they take care of it and send me on my way. December of 2019 my truck starts doing the EXACT same thing, except now i can't even do anything but shift my truck into park and restart it, every small touch on the brake shuts my truck off. Now i live in the mountains, and we have a lot of hills. Imagine driving a blacked out truck in the middle of the night on a hilly road with no lights and your truck completely cuts out. It was sketchy. I go to the dealership, ONCE again. They replaced a WHEEL BEARING. Saying it caused the issue. tf... To my surprise the truck has been fine. Fast track to June, present day. Drive my truck for a half hour or more, the problem is back. Now i am pissed. My boyfriend and myself do research and we found a youtube video about GM trucks and problems with G218. All the exact problems to a T! i brought it to the dealership this morning, they refuse to do anything until the truck signals any of these problems. Instead of popping open the dashboard to even just look. It has been 6 hours and now they are keeping it overnight. 40 minutes from where i live.. I am pissed. I did my homework and presented it to them, thought they had listened but apparently not. From how it seems, i am not the only problem having this issue with 2014+ older GM trucks. Everyone keeps saying this needs to be a recall but the dealerships WILL NOT listen. I know people on this forum who have spent thousands on diagnosis's for their trucks to just have them messed around with. Anyone else having this issue? I would love for my boyfriend to just fix it but then it voids my warranty. How the hell do we get GM to acknowledge this and make it a recall. I am by far not the only person having this issue.

Ive got about 12k miles on my 2018 Sierra SLT. Last week I started getting the “service stabilitrak” message nearly every time I went through mud. I took it to dealer and they said there was a TSB on it. Said it was mud/debris hitting underneath the truck, for which the remedy was to spray some dampening coating. Well, I was out deer hunting this afternoon, went through some mud... ding... service stabilitrak. Any ideas?

I have a 2017 Silverado 1500 and just this year when the cold weather started, in the mornings when I start driving I get traction control off, stabilitrak off, and brake fluid low messages. I don't lose power and nothing else happens. After the sequence the traction control turns back on. It does it when I start accelerating and sometimes just random while driving. Anyone having this problem?

Okay so I have a 2008 GMC Sierra with 130 on a 5.3. It's my daily driver and now has some issues. Basically a misfire in cylinder 2 that I would like any good help with before I keep trying new things that might not work. So the stalibitrak and traction control lights also flash and are on regularly which started at the same time. Meanwhile the engine light has flashed for a couple seconds but is usually solid. It is a p0302 misfire. So far I have cleaned the MAF, checked for leaks, changed all spark plugs, coils, and wires, ran some seafoam through it at the brake booster line and some in the gastank. I pulled the new spark plug after it didn't work for inspection and it was very carbon fouled after 3 days and very little driving. It runs good at higher speeds but idles rough and loud I would say klunky. Has not stalled. So Does anyone have any ideas before I keep changing things that are not the problem? 2008 Chevy Silverado/ 08 GMC Sierra 5.3

Hopefully you guys can help me out here a bit. I have a 2014 Silverado CCSB Z71 5.3 with 38000 miles on it. I was driving to work this morning and had the reduced engine power alert come up in my DIC along with the stabilitrak light. I pulled over, shut the truck off and re-started a few times with no success in clearing the codes with drive cycles. While driving, the transmission was banging gears pretty hard and the torque converter was clunking worse than "normal, by GM standards". I got to a good spot to park the truck and that is that for now. I am anticipating a tow to the dealership as I am about 20 miles away from it now for what will hopefully fall under the powertrain warranty as my bumper to bumper was up 1 months and 2k miles ago. Anyone have a similar problem with this or any insight as to what it may be. Im iffy on driving it home to scan it, as I dont want to compound any problems. I drove the truck Saturday night, probably 60 miles on the highway with no issues and it sat in the garage until this morning. Help me out, internets!

My warning lights come on when temp outside is in the 40’s and below. It says “ Low Brake Fluid, Stabilitrak Off, Traction Control Off” and this morning it also said low coolant. I live in south Florida so this happened last year when I went to Ohio in December, the truck had 12,000 miles on it. Got back to Florida and it happened one cold morning so I took it to dealership. They could not find anything wrong. Later with 38,000 miles the low coolant light came on. I took it to dealership again, they could not find anything. Now I am back in Ohio for Christmas and the lights started coming on again when I got into colder weather. They do go off at times while driving but come back on within 10 minutes if the temp outside is still below 40. It is very annoying as the warning bell starts going off and the lights flash. Any advice?
