Bad glow plug. Had to order it. Going back tomorrow to get it fixed. On a side note I noticed my remote start quit working before the engine light. They said the glow plug was more than likely the issue there.

CEL causes remote start not to function on previous generations as well.

Just a heads up....there is a known software issue based on a GMC Service Bulletin where the NOx sensor is incorrectly reading the exhaust values. There is no fix in place as of now, as the Engineers are working to update the software. I had mine come on at 1700 miles and serviced. They cleared the code and its back. No issue with Glow Plugs and etc.

is that code P20ee? mine just popped that up saturday

i got the same P20EE  (emissions issue) yesterday with 565 miles on my 2 day old 2020 3500 Denali...(500 of those miles were from the dealer driving it down from another dealer).

 

also, no remote start, side veiw mirror indicators only turn on when a car is half way past, got email from onstar saying problem with my airbags (Onstar rep says they have no record of it!), screen blacks out occasionally...not happy.  I've had Yukon XL's for a long time-never a problem.  This truck though---...

Dealer says there is a service bulletin w/fix for the P20EE per "PIP5664A" this also covered an issue that may indicate the air bag has issue.  Just got them fixed today...we'll see if it sticks!

      OCI, not when but why?

      By KARNUT · Posted

      It seems fine because it pulls everything out of a hot engine. I’m not going to worry about a thimble full with 5K oil changes with synthetic oil. Every other oil change is at Honda they pull the plug. I watch them through the process. It turns out going to Honda what amounts to their normal oil change intervals.

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.
