Want to get a poll together since this is a new engine to see who owns and have had problems with this new engine.

Yes I know there is a lot of info.  I personally haven't had issues with mine.  I have seen a few were they can't get engine/emission issues resolved.  I just wanted to see for us who own one, how many people are having issues since it's a new engine

No problems with the 3.0 duramax motor . However I just took mine in to the dealer for transmission fluid leak . They are going to race the torque converter seal. I’m not to happy about that.

Diesels are prone to problems with all of the emissions crap the government requires.  My last vehicle was a 2017 X5 35d and I  had EGR valve and pump issues immediately after taking delivery.  About a week at the dealer to replace the defective parts and had good performance thereafter.  Before that I had a Benz diesel and drove it 70k miles with zero issues.  So all told I have about 7 years and 100k miles of experience with diesels albeit German diesels.  Started out looking for a Sierra 1500 diesel but ended up with the 6.2 and am happy with it.  The days of the V8 are numbered and since this is my first truck I went all in.  That said, the GM 3.0 Duramax is a well made inline 6 and has a good rep so far.

What I miss the most about the diesel is the range.  Could get close to 700 miles on the Bimmer and the Benz.  Will take 2 tanks to get that with the 6.2!

I’m getting anywhere from 23-27MPG in town. On the highway I can get 31-32 MPG with the 3.0L Duramax. Not bad considering my previous Ram gas truck was lucky to get 13MPG in town.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      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!
