Thx all. I'm very skeptical of any add-on warranty. It's like insurance, I hate insurance, but I got cancer when I turned 65 and thankfully, everything was covered 100% by Medicare. One year earlier, and I would be screwed!
I am mostly concerned with the AFM/DFM issue. I have searched, and read, until my eyes crossed. I'm looking for the definitive answer as to whether my 6.2 has the earlier AFM or the improved DFM. Is there a production date or VIN range published somewhere that would tellk me? I read that 2018 was the year it changed, which is why I bought the low mileage 2018. Also, what are the production numbers of 2018 6.2 vs the number of failures reported?
I will try again to find those answers and share them if/when I do.
the L86 has AFM, the L87 with DFM wouldn't be in a 2018 (K2). It could be a T2 2019 silverado and is what they use in 2021+ T2's SUV's
generally the Silverado's have been given the updated designs a year earlier than the SUV's. But GM also makes what is called a LD (last design) with the pickups so there are some 2019LD silverados out there
2014 silverado's got the k2 update a year earlier than the SUV's
2007 silverado's were made with either the gmt800 or gmt900 platform
2000 yukons were made in either OBS or GMT800 platform, same with some escalades I think, unsure on tahoe suburban.
generally it is a good idea to stay away from a new model year (2018 is not a new model) because for one they can have design bugs and then gm will tend to make various changes over a short period of time making it hard to get parts for a particular year.
the K2 design alone 2015-2020 suv's saw changes in the transmission of 6sp, 8sp, 10sp some changes were mid year it can be all screwy same with rear axle ratio a lot of them got 3.08 a few got 3.42 depending on the tow rating or engine. a few unicorns got the 6.2 that were not denali or escalade, same with the pickups
some have a regular key, some are push to start, some have a regular shifter, some have push buttons, some have regular cruise, some have adaptive cruise, some have both regular or adaptive (switchable), some have automatic high beams, some do not, some have HUD some do not. the list goes on....
If you are shopping online for a K2 and you want specific features it can be a nightmare because most dealers or sellers DO NOT list specific features or they are listed incorrectly or they don't even know..... so then you have to hope the pictures show it.
