Are Yukons/Tahoes reliable?

07 - 08 - 09 6.2L Yukon Denali and Escalade without the AFM / cylinder deactivation feature. They’re hp/tq & AWD makes them feel like you’re in a smaller vehicle. It’s a 300k+ mi truck

Escalade has the uncommon air conditioned seats (not vented). A/C seats went away in 2010. It’s an option on 09 Denali. Both run e85 starting 09 and a 2WD option that year too.

You’ll actually be looking forward to your 6SP trans giving out because you can now add a 2019+ 10SP trans to improve milage, launch and not feel it shifting at all.

2016 5.3 traded with 170k miles no issues
2017 5.3 traded with 70k miles no issues
2020 6.2 10 speed treated with 107k miles

The first two had lifetime powertrain warranties, but the 2020 did not do I took the opportunity to get a 21 upgrade

My first GM full size was a '79 GMC Suburban, purchased used with 85K on the 350 ci V8 and TH350 trans. It was 2WD. I sold it to my sister-in-law with 200K on it. She was a newspaper distributor and hauled papers to her carriers every day for 3 years. Never had a failure of engine or trans, retired the truck with 350K miles.
I had a 2001 Chevy Suburban, 5.3 Flex-Fuel/4L60E 4x4. Traded it in on a new 2005 GMC Yukkn XL 5.3 Flex-Fuel/4L60 4x4. It now has 268K miles. I have had no engine problems at all, and had the 3rd-4th gear assembly fail at 145K. Dealer repaired it and I've had no problems since. Have had to replace the MAF sensor once, and the Evap vent relay for the fuel tank. I do not intend to buy another vehicle. If I do have an engine or transmission failure, I will replace them with remanufactured units. If I HAVE to buy another vehicle, it will be another Suburban or Yukon XL.
