I had a similar experience just before 2000 mi on my 2015... sure looks like they are delivering these with barely enough DEF to get going....

Since I filled it the warning has not come back and I am nearing 5k miles.

Mine was the same. Apparently since before the 15s gm dealerships didnt even carry def so they are forgetting to top off during pdi. You get free top off on def for first 2 years on the 15s. I just went back and had them do it.

No way. GM diesels have used DEF for several years now. You mean to say that with all the thousands and thousands of Duramax trucks sold the dealer couldn't fill the DEF? Unlikely.

Mike, I don't know of very many people who own DMaxes that got more than 1000 miles before they got the message to add. I think that when they do the PDI not knowing how long it will sit on the lot they don't fill it up and then when they sell it they have forgotten that they need to fill it up. A friend of mine bought one two weeks ago and I told him he better fill the DEF up when he got fuel the first time and when he pulled in to get fuel he got his first message for 1000 miles left. :jester:

Can DEF not sit in an idle truck?

 

I'm not saying some dealer shithead wouldn't overlook filling but I seriously doubt that dealers are just getting DEF in stock.

The dealers have had def systems since 2011 when it was introduced. Maybe they don't fill them because the def does go bad after a year

I had a dealer who didnt check/fill my trans fluid it was 2 quarts low, once warm shifted hard and slow like it was hung up, check fluid and it was bubbly and low. 1 day old. So when I bought my '14 I had dealer check all levels before I left. Fluid good- lug nuts lose tho.. Wtf?

Dealers are not to fill the tank during new vehicle prep. The fluid is supposed to be filled upon delivery. DEF has a longer shelf life if kept at a constant and cool temperature (i.e. parts department, etc. in the dealer). In the truck, it would get hot and shorten the life of the fluid during the summer (causing DEF quality issues) and freeze during the winter due to the fact that its 67% water. Trucks can sit for months on end on the lot.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Different requirements for oil filters?

      By Grumpy Bear · Posted

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
