Need Help Please!!!! I truly appreciate anyone that reads this long post. Hopefully someone can help me figure this out. Bought my 2017 Silverado CrewCab LT Z71 new. For 5 yr & 10 mo. the temp gauge sat at 210 with no issues and no variation. Then, in June 2023 the temp started rising about 10 degrees and would fluctuate from there back to normal. Thermostat was replaced, didn’t resolve the issue. Temp sensor was replaced, didn’t resolve the issue. Truck is well maintained, radiator/coolant flushes done a normal intervals with no issues found. Dealership has checked out this issue 3 times and says it’s operating as normal, temp fluctuation is normal. I have been calling BS on this since June, how is this normal? Almost 6 years with no variance but now it’s normal? So here I am in October, with continued temp issues that are anything but “normal” The temp gauge has progressively increased, the gauge goes up to 245-250 then will drop back down to 210 and fluctuates between 210 - 230/235 as the drive continues. Things to note: I have never had a Check Engine light, adding to the frustration. Coolant level doesn’t change, no leaks whatsoever. This temp issue does not happen when idling. I’ve idled for 20-30 min both from cold and after driving with the issue happening, no fluctuation. I have thought through some other possible issues but then wonder could it be “this” when the issue is not consistent or throwing codes. Are the active shutters not opening / operating correctly, that should throw the check engine light Belt is loose, again should be a more consistent issue with sounds and other functions having issues. Water pump going out, again I think that would cause more consistent issues and would overheat the engine. Fan(s) going out, wouldn’t that be more of an issue when idling vs driving and would be a more consistent issue. Could this be some other sensor, relay, electrical issue. Any help, experience, and/or suggestions you have on this issue are greatly appreciated.

Has anyone had this issue? sorry for lengthy post but its all details that are odd. 2019 z71 LT issue free. Daily driver ~60 miles per day. All was normal, as I was pulling into a gas station, the truck dinged and gauge said service ESC, reduced engine power and shut off. didn’t think much of it because it happened as I pulled up to the pump. Filled up full tank, go to start it, and it cranks with no start. The starter and battery are strong, it cranks like normal, but no start. Thought it was fuel pump at first. Called the tow truck after 30 min of checking all fuses and disconnecting the battery for a few min. About an hour after multiple attempts of crank no start, tried to give it another shot and to my surprise it started but ran very rough. I immediately shut it off. Gave it 30 seconds and thought I’d try again. To my surprise again, fired right up, smooth as butter. No ticks, no rattles, no smoke, ran like normal. Gave it about another 5 min to idle beforere driving home, with no issues. Started driving home and after 15 min of driving, the truck dinged again, flashed service ESC, reduced engine power, and shut off. Pulled off on the side of the road and this time waited for tow truck. It did not start again no matter what i tried. When the tow truck brought it to the house, the driver wanted to put it in park, but accidentally held the brake and pushed to start and the truck fired right up. With no issues. Drove it off the tow truck and when I tried to move it 10 min later, it would do the same thing, crank no start. I scanned for codes and had 17 DTCs at first, once cleared, 9 DTCs remained with Ignition circuit issues. I went through all fuses and relays under the hood, driver side, and passenger side fuse boxes with multimeter and all tested good. Also tested relays with 12v power to each relay at pin 85 and 86 for an audible click. All tested good. What could be the issue? Was thinking a ground cable? I am open to your thoughts and ideas. Thank you in advance

I have a 2005 Silverado that shakes above 65mph. I have replaced rims, tires (had them balanced), shocks, controls arms, springs, carrier bearing….and the shake continues. Any ideas? Would bad rear Axl bearings cause this?

So I go to start my truck and it runs fine for about a minute and then starts rough idling and sounding like it’s misfiring. I have no clue what the problem is. Doesn’t throw a code and I have scanned it. 2016 GMC Sierra 1500 5.3L V8 140k miles

2019 Silverado facelift 5.3 103000 kms getting the generic Misfire code when I scan it it shows service esc, service parking break and a flashing CEL. It has a rough idle and clunks hard when coming to a stop almost like being rear ended. This isn’t what’s weird it also occasionally billows white smoke out of the tailpipe for around 10 seconds this only happens about once every 2000 Kms. It also backfires occasionally and sometimes is a little extra Smoky the smoke isn’t blue it’s a thick white but doesn’t smell like coolant it smells like gas the coolant and oil levels also never change the normal exhaust also smells very rich spark plugs look fine I changed them and the coils dealership says they don’t know what’s wrong with it can anyone provide me some insight?

Recently bought a leather steering wheel from a 2012 2500 sierra. I swapped it into my 2007nnbs silverado ls/base model. I've searched for hours trying to find the correct information on what I need to get the radio controls to work. The harness that came with the wheel had 1 more wire than the ls model did. Original harness had 6 wires. New wheel had 7 wires. Everything I looked up said the swap should be plug and play. But it is not. I need some help to know what I really need? New clockspring? Different harness? Harness behind clockspring? Or is it just not compatible at all? Picture is of new steering and harness that came with it Thanks everyone!

Hey guys so I asked on Facebook and I didn't really get very far so I figured I'd bring it up here. 120,000 mi completely stock. Here's what's going on. so with the converter locked and I believe in 5th gear around 1500 RPM I randomly get what feels like a misfire when applying light throttle until the turbo spools up. I bought this truck from an auction all the glow plugs were bad replaced all those. The truck had some dead battery issues right before it went to auction so I looked at the stored codes but ended up clearing them because a lot of them were communication codes which would be related to a dead battery. All filter replaced, all fluids (except trans and xfer) replaced. I meant to write down the actual codes but one of them was for EGR and the other ones was for glow plugs. I've replaced the glow plugs everything is completely fine as far as that goes. the filter head does like to lose a little bit of prime overnight so if I just fire it up first thing in the morning it'll run a bit rough if I put about two pumps onto the primer it runs completely smooth after start. I have conflicting data from different scan tools some of them are showing the EGR experiencing large error % as far as deviation. My all tell is showing small amount of error (2% at idle) but not enough to trigger a code. Doesn't feel like 605 torque if I'm honest. Pretty sure my 8.1 could out pull it at this point. Here are the fuel numbers Attached is some OBD live data First few are some screen shots. The one with the date is the most recent. Here is a link to the EGR doing it thing last week while I drove around town. Big drive south (AK to AZ) supposed to start tomorrow night. But I don't want it to brake down in the middle of nowhere.

So I was pretty stupid yesterday and I just got a this beautiful 2016 1500 30k miles in the crimson red and it came with theses butt ugly pinstripes so of course I did what any one would and went and got a 3M Pinstripe eraser wheel and took it to the pinstripes and my speculation is that I had the drill on too high of a setting possibly on the first section as you can see in the pictures it left like a yellowish streak mark in the paint. Then I turned the drill way done and suprize suprize the rest of the truck looks flawless. So what do you all recommend I do to correct that section? I’m really not even sure what to call the damage. Burnt? Thanks in advance.

Thanks for the add. Greetings All!! Going to start my membership, by asking what I hope is an easy question. On an online site, they have a deal on a power retractable tonneau cover that I really like, (like same price as non-powered), but I also just installed a Weather Guard tool box. My hope/want is that I can put the retractable canister in back of the toolbox, (tailgate side) and then mount my onboard air tank under it, with the compressor in the toolbox. Finally my question is; will the electric cover stop at my tailgate automatically? I understand I have to cut the rails to accept the canister in the different location, but the cover stopping in the correct stop has me guessing what other mods I’ll have to do. please help ASAP, as I do not know how long this deals gonna last. Thank you! Collin 2018 GMC Sierra Denali 3500hd

The transmission went out last November in my 98 k1500. I started it up a few times afterwards ( over the coarse of a month or so ) with the transmission still out. I have let it sit since then . I am fixing to get the transmission rebuilt and get it back on the road , but for some reason the Anti theft or “passlock” system has activated . It won’t let me do the “relearn procedure” either . I have no idea why it has activated and don’t have the money to by a new bcm or ecm. Can someone explain why it activated ?

Hi... im in need of the spring arm assembly from a monroe hauler air suspension. Having some trouble locating one.. yes I've called monroe. Yes I've called some junk yards. YES I GOT RIPPED OFF FROM A GUY A DAY BEFORE X MAS SAYING HE HAD 2 OF THEM. YES IM AN IDIOT. I'm giving this one last try before I go ahead and make it 4 link.. she needs to get back on the road asap. Love Ed

So this one is a little complicated I drive a 2011 GMC sierra denali, it has the 6.2L V8 with long tube headers and cold air intake. It has also been tuned trying to fix the issue with no luck. While driving about 30-40 mph it begins to buck or lag like the truck is misfiring but there are no codes and i dont believe it is actually misfiring. it seems to struggle unless i am on the gas constantly. It has a similar issue when in the 50-60 mph range as well. Any other time the truck seems to run fine. The best way to describe the anomaly is it seems to oscillate almost for the time it does this instead of smooth acceleration or smooth cruising. It isnt the tac either, it can be heard in the exhaust that it is not running smooth. The things i have done chasing the problem: New injectors, new spark plugs, oil catch can, new spark plug wires, tune, replaced transfer case, cleaned throttle body, new throttle position sensor, new crank shaft position sensor, cleaned all grounds, new MAF, new MAP, new o2 sensors, new air intake manifold. I am starting to think this truck will never be fixed. HELP WANTED lol Thank you for your time.
