Vehicle Details 2023 GMC Sierra Denali with a LZ0 3.0L Duramax Diesel. It has 7,300 miles in total. Issue DEF Level indicator not reporting proper fluid level. At startup, with DEF tank full, the center dash display shows “DEF Range 200 mi”. If the level drops by one gallon below full, the display shows “DEF Level Empty” and you can not use any of the other center dash displays. It locks the display and only shows “DEF Level Empty”. Appointment With Dealer After arriving for my appointment and explaining the above for the second time, 1 hour and 20 minutes, they said I was all set. They didn’t perform SB # 22-NA-150. They reset the DEF system and cleared its data. This seems to have corrected the issue, but I’m not confident that this is a long-term solution. The DEF level indicator still is reading less than full when the tank is, like it will show no higher than ¾ full. Anyone else having this issue? Any long term fix?

Ok, something just started happening with our 2016 GMC 2500HD Denali 4x4 with the diesel. The remote door lock and unlock won't work every time from either of our fobs. We bought this truck last August so I can't imagine the batteries in both of our fobs have died at the exact same time and only 7 months in. My fob gets used the most with my wife's fob barely getting used at all. Anyone else experience/experiencing this? And, what did you do to remedy it? I guess we can try replacing batteries first, but batteries only lasting 7 months in a fob? And both failing at the same time, especially given one gets frequent use and one barely gets any use. We know it's not a fuse because it does work from time to time.

Has anyone found a blanket that fits the lm2 turbo or modified one to fit? Amazon has some inexpensive blankets for other turbos I wouldn't be against modifying. https://a.co/d/8BgHzyR

Hello, I am about to buy a 6.6L Duramax 14' 2500hd Sierra with 136K on it. But I just learned it has a small heating core leak, the dealer is replacing the whole core prior to purchase. Should I proceed with this purchase? Or is this the sign of this truck going down hill. The service recorded were regular until 2018 then the car fax no longer shows any updates. Any help would be appreciated, I have a 92 Sierra with a 5.7L small block so the diesel world I am not as comfortable with. Also do not want a newer truck as I do not want to deal with DEF and I would not be able to do a delete.

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. -
Shopping for a used 3500 - drowning in options
alku1 posted a topic in Dealerships, Pricing & Orders
Hey folks, We are looking forward to do a 5th Wheel roadtrip with two small kids this sping-fall cross country and may be even into canada. Currently, we are aiming to get a 5th wheel in the 12.000 GVWR range (pin weight ca 2700 lbs). Now we are shopping for a tow vehicle. Since we are out of country we are just looking for a limited time ownership of 7-8 months, therefore budget is not so much an issue, as long as the prices remain stable. But was hoping to find something in the 40-50k area. However, we never owned a truck and I was hoping to find some guidance on what to look out when buying used and get any tipps for "best" models since Im absolutely confused about the different makes per year, trim levels, tow pachages etc... What does "best" mean? An equal mix of reliability, driving/towing comfort and MPG. Requirements based on aboves 5th: 1 ton truck that provides >14'000 GVWR and payload > 4000 lbs; (SRW, 4x4) long bed/8" (piece of mind and dont have to go for a slider hitch, extra storage) diesel "crew" cab?! the bigger option (to comfortably seat 2 kids, potentially also SO during feeding / play times ) Questions: Is there any specific year as of which there are crucial differences in the truck? Any mile thresholds we should have in mind? Is it OK to buy above 100k miles? Anything we should specifically look for / check at the particular truck? What trim levels are required/ usually meeting the above tow requirements? Or anything else I can differentiate potential offers? Unfortunately, there is sufficiecnt filter at autotrader, so Im currently screening 1 by 1. Any other sources besides autotrader we should check out? Since we are out of country, we have some flexibility locationwise (potentially using third party inspection / delivery?!). As of March we would probably focus around Raleigh NC, where we start our journey and have family. Thanks for any help, really appreciated!

Ok, I want to come back to the GMC/Chevy family. For over 20 years, I owned a 98 GMC Suburban, putting over 230k miles on it myself and LOVED the truck. I too owned a 2003 Chevy 1500...put many miles on it too. I am looking at the GMC/Chevy 2500 series diesel trucks. I will stay within the 2016-2019 year range, with about $35k plus'ish budget. I might look at the 2021 trucks, only due to many deals/rebates etc. What suggestions or tips are out there for these trucks? What should I watch out for and/or look at getting? So, a few years ago, I bought a 2015 Ram 1500 4x4 EcoDiesel Lonestar -- well, I have been disappointed with Chrysler/Fiat (FCA). Short story, they lied about the ecodiesel, and after forced recall ECM update, they sucked all performance etc., from the truck. 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 -
Bought this vehicle brand new. I love it, and perfect for myself, my family, and the fact it's Diesel puts the cherry on top for me. But... now things have started. We have currently 1,137 miles on the vehicle and had the first message populated: - Service steering column lock. (see photo) Everything else worked, remote start, standard start, and the vehicle had zero issues. The following day from our road trip, we had to go to the DMV with our out-of-state paperwork to submit for plates. My wife now received a new message. - Service emissions system. See owners manual. (see photo) She drove to the DMV and left to get the smog paperwork. Then a new issue: - Vehicle remote start isn't working. (see photo) She is in the car and tries to start... Nothing. She tries again. It starts, and she drives it to a local dealer. They come to look and scheduled us for an appointment. She drives the vehicle now, and Onstar now shows the emission issue. ( see photo ) We now can't register the vehicle in California, because, the check engine light is on, emissions warning, and they won't smog it until it's corrected. Awesome... I noticed that none of these issues happened until it updated the software in the vehicle. I'm hoping this is something that can be fixed. I've been looking around for answers and only finding more issues that are all pretty shitty. Sorry, no better way to say it. I've also seen a post of people saying, “deal with it, it's a new breed of vehicles,” etc. I’d challenge that answer. No one should pay this much for a vehicle and face these issues I'm reading about. So here's what I'm going to do, document everything, and I mean everything. This will be for everyone who may have this issue now or who may come across it. My opinion...but I'm not a mechanic, is that there is a massive software and hardware issue with these models. I believe GM internally has to know about this from Dealers, Customer Service, Compliance Reports, etc. I'm sure all issues are in the queue to be address or fixed. I do, however, feel with the challenges of physical hardware that they chose a vendor that was most cost-effective, which is a component of these issues a long with the capability to support the software complexity of the current models. Or maybe I'm just wearing a tin hat, who knows. So, I open this up to you. Any advice, similar issues, outcomes you've faced, and other topics, please comment below. May the journey of dealership visits begin. Hopefully, this journey isn't to long.

I just bought a used 2021 AT4 with the 3.0 with about 3,800 miles. This is my first diesel but I have read a ton of documentation, forums and Facebook groups specific to the 3.0 Duramax. When I got the truck I scrolled through all of the information in the DIC. I noticed that the DEF gauge is a about a third full. I figured the previous owner may have done a lot of towing with it because at 3,800 miles it should not be that low. Am I correct in that assumption? Should I go ahead and fill it up or wait until the truck tells me to? How much do I fill it? Until full? Thanks!

Had a 2018 Sierra 2500 for a loaner while my 1500 was having warranty work done. We got a couple 0 degree days here in St Louis during the polar vortex and the 2500 went into limp mode and wouldn't allow me to go above 25 mph. CEL came on and a message popped up "Reduced Engine Power". I was 30 miles from the dealer that loaned it to me and they sent someone out and gave me a 2019 Silverado 1500. Next day they towed the 2500 back and found the diesel fuel had "gelled" from the cold temps. Curious, is this common in diesels? I let it warm up for at least 5 minutes before driving as I know diesels need a little more warm up time than gas engines. How could it idle and drive up to 25 mph with the fuel "gelled" as the dealer put it? Didn't shake or sputter, just had the rpm limiter kick in at 25 mph. -

Ok guys (and gals), I am very likely in need of a second "loaded" work truck this year. Having been a Cummins guy for the last 22 years but since 2017 an owner of a Yukon and as well now a Camaro the way the new GM product is spec'd it has all the bells and whistles but still functions like a truck, minus the solid front axle. Having tested a new 2021 3500 AT4 DMAX - I really like it. I love the upfitter switches, the HUD and the ride is as good or better than my 2012 3500 RAM (which has aftermarket FOX 2.0 shocks and a nice lift). Now for what I do, it still needs to be leveled out as that front lower valance will get ripped off in a week but otherwise, very nice. Comparing to a similarly equipped 3500 RAM and honestly, and this is coming from a RAM guy, these aren't even in the same park, let alone field. Sure the Cummins is great but the truck felt a tad cheap and when both are over $100K (CDN) it has to feel right. The other big gripe I have is with that 12" screen. I love tech but if you just want to turn on the seats or something, there are too many screens, too much distraction and frankly as I do a lot of driving at night, even turned down it was too bright and made it hard to see outside. So for this knowledgeable group here are some questions: 1. cost of ownership? this will be a work truck and not a grocery getter so it will do a lot of long hauls but more so, a lot of slow bumpy driving on goat trails. So is the drive line up to the task? I don't want to be getting alignments every other oil change or whatever. 2. V8 DMAX vs I6 Cummins - again cost of ownership? will I get 400,000 km before I need to do anything major with valves, rings etc.? 3. I do a lot of idling (no comments from the greens please) so this must be able to handle that without burning a bunch of fuel (or something might just fall off). EGR? DPF? DEF? 4. I wasn't planning on a shorter than 8 FT box but I really don't need another "barn on wheels" so is this "standard box" good enough? 5. GM 10 speed auto vs the RAM 6 speed auto? The RAM is not all that great but I know how to fix it. Now to throw a wrench in here, I started looking at the 1500 AT4 but quickly found no upfitter switches and it needed a 4" lift kit even though it claims to be taller than a regular sierra - although frankly, that is marginal at best. I though the 6.2L would do me fine with the 10 speed auto but I am concerned about my 10 year 400,000 range I typically consider for replacement but equally thought that I could add a 2.7L super charger to it after the jobs and make my own version of a Hennessy - because I think I could do that. So, thoughts? comments? am I crazy? remember, work truck, long distances, lots of idling and so on... Any help would be greatly appreciated. -
Picking up my first ever Denali on Saturday and can't think of what music should be played first. Back in 2004 when I picked up my Colorado I remember playing Collective Soul - Perfect Day which is pretty much what it was. This time, I can't think of anything quite as fitting. Suggestions? What music did you choose for such a significant event? -
i have a 17 l5p and took off the intercooler pipe for the turbo on the driver side to replace some parts and i everything back together as soon as i got on the highway the bottom connection fell of the intercooler and ran for a couple minutes after realizing it had disconnect, after that the truck didn’t accelerate and turned off, i secured the pipe and turned the truck on but only runs for a couple seconds and powers down, the turbo starts making unusual noises and it blows off air thru out the air filter suggestions what the problem is?
