Good Morning Yall,
Long time lurker, first time poster as a member, and really appreciate this forum.
Recently the past year I have had some symptoms that didn’t affect the drivability of my 2014 Silverado z71 4x4 5.3, but were very present on a random basis, especially during rain.
Service Stabilitrak, Service Trailer Brake(nothing being towed) popping up the screen, sometimes binging back to back for extended amounts of time near to 30 minutes frequently.
Today the truck would not start, and presented these codes above under a check engine light. The truck started after having the battery disconnected for 15 minutes and has started since so far the previous 12 hours. Also while driving and the typical service notifications, one headlight being out, the truck engages the transmission at a slow roll/acceleration and a very very rough/lurching, almost feels like being rear-ended engagement, it would not engage power steering, and also presented a warning of reduced engine power. Some of these symptoms of course seem to be directly related to the codes, but seem to have progressed as time has gone on.
One issue noticed was a tail light having a small crack, and a sliver of water pooled inside of it. I am unsure if that may be related to the issues present, but I have ordered new lamps.
I have also previously installed a new ground cable from the battery to the block, and also verified the ground on the driver-side front beneath the dash/tweeter. The battery also tested good, so did all of the fuses on the battery side and the box side with the voltmeter. I have not checked the starter or alternator, but they are less than a year old.
Any help or suggestions would be greatly appreciated.
I have a 2012 Suburban, owned since new. Yesterday the key fob / remote / keyless transmitter stopped working. It stopped, then worked a couple times to unlock, then quit completely. I assumed it was a bad battery (10+ years old), so I replaced it with a new battery, still didn't work. I have the second remote that's only been used a couple times when the keys were "lost", and it doesn't work either. No response from any buttons. I checked the batteries in both, and both batteries are at 3.3 volts. I pulled the DSM fuse for 5 minutes and then disconnected the vehicle battery for 5 minutes, no change. I have tried holding the remote right next to where (I think) the RCDLR is in the left-rear pillar, still no response. The TPMS system works fine, reading all 4 tires correctly with no errors. I hooked up my ODB2 scanner, and it doesn't show any codes.
Do I have two dead remotes? Or has the RCDLR partially stopped working? I called the dealer, all they said was "buy a new remote, your two remotes have died". I asked, why would an unused 10 year old remote die? No answer, just come in and buy one. I have no faith in my dealership's service department based on previous repairs unfortunately, so I thought I'd ask here. My local locksmith will attempt a re-sync for $50, but they said if they're both not working it's not that. Unfortunately this year model won't allow the user to add or reprogram a remote.
Thanks in advance for any ideas of what to try, or what might be the issue.
TIA for your help and time…
BLUF: Ticking noise under truck, not heard from top of engine compartment.
I noticed a ticking/clicking/pinging noise under my truck today, took a video, hopefully you can hear it. Anyone else?
Truck was in Park and Neutral (Parking brake engaged) and still heard the sounds.

Reciently the Check Engine Lamp (MIL) came on at start and remainded on with no noticable engine running rough. The error codes were read which indicated 400+ Cold Start error codes on Cylinder No.3. Their are several GM Service Bulletins (PIP5498M, PIP5628E) on this subject V8 on engines from 2000-2022. The bulletins indicate the "Cold Start" causes misfires due to coolant entering the at the liner to deck face casting or the casting line in the intake port of the cylinder head, in my case No. 3. The GM Service bulletins indicate "engine replacement" is needed to fix this problem. I have been very happy about this vehicle however, at 67K miles, this type of issue should NOT be occuring. Apparently GM has know about this problem since 2000-2020 model years described on the attached Service Bulletins.
After Two days of MIL being ON, the lamp is now OFF. My question is how can the problem described repair itself and could the diagonistic codes be attributed to another problem? I was under the impression that once the diagonistic code is initiated, the only method of turning OFF the MIL is by resetting or clearing the codes.
Tips | Suggestions | Advice - Looking at buying a Chevy/GMC truck. What should I watch out for the GOOD and BAD?By SlowerTrafficKeepRIght
What suggestions or advice is available for buying a GMC | Chevy truck? What should I watch out for -- the GOOD and BAD?
I want to come back to the GMC | Chevy family. For over 20 years, we owned a 98 GMC Suburban, putting over 230k miles on it myself, and I LOVED that truck. Other than typical wear and tear -- I never had any problems or issues with my Suburban.
I am looking at 2016-2022 -- GMC | Chevy 1500 | 2500 series, all trims (4x4), except the base models. My budget is around $35k plus'ish; yes, I understand my budget limits what I can get. I am a USAF retired veteran living off a fixed income.
Yes, we tow hitch pull RVs and various trailers, but not as often as before. What are the GOOD, BAD, and UGLY these days on the GMC | Chevy trucks? Is the additional price for either diesel and/or 2500 worth it?
SHORT STORY: so, a few years ago, I bought a 2015 Ram 1500 4x4 EcoDiesel 6cyl w/turbo Lonestar -- well, I have been disappointed with Chrysler | Fiat (FCA). They lied about the EcoDiesel, and after forced recall ECM updates, they sucked all performance and mpg from the truck. Buying a newish GMC | Chevy, I do not want to fall into what happened with my 2015 Ram. When I had my suburban, I never had so many recalls, been lied to, and never had poor performance.
Thanks for any suggestions that you will provide -- Gary (ExFalconFxr)
