It's alright looking, has some really aggressive looks but I don't like the HD truck front clip on an SUV, they look great on the trucks but not that. or the humungous flared fenders and it has side markers and clearance lamps like a dually.... I don't know i'd would have to grow on me, maybe with some time.

There are some things I don't like -such as the marker lights on the fenders - but overall I think it makes a statement that the burb is not a sissy - but a serious tough truck.

I agree on the whole, why use the Silverado front clip. When the Chevy Suv's have the best looking front clip of all the 900 series designs IMO. My second favorite front clip of the GMT 900 series is the Siera, so I imagine if this Diesel Suburban is production ready like it looks to be, I imagine there is a GMC version that will be pleasing to those of us that don't care for the Silverado HD look, provided they use the pickup HD front clip on it as well. I realy like the wheels they used. I hope those make it into production. Those good looking 8 lug rims are something GM has needed for all there 3/4 ton trucks for years.

The engine is the real story here. A compact 4.5L diesel producing at least 310HP and 520lb-ft of torque? I'm very much looking forward to this oil burner. Having this engine available in half-ton Silverados and Sierras is going to be huge. Can't wait. It's too early to say for sure, but based on early information it looks as though GM might have hit a home run here.

    • Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
    • Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."    
    • Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.  
    • Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
