On at 1100 miles. We shall see tomorrow...

3500HD or 2500HD? Which engine?

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!

    • I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome. 
    • Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
