Reliable Gas Engine Years?

My 2010 Escalade EXT had the first 6.2liter motor with AFM and it was one of the first off the build line as it was a GM corporate vehicle. I bought it with 10k miles and 10 months after production. It's still on the road has 180k miles, it doesn't burn oil and I never had any issues with the motor so I think it's luck of the draw with a bum motor. It doesn't make sense that every motor with AFM was going to fail for those first few years.

I suspect you also are changing the oil at the recommended interval or just prior and using the correct oil type/weight. A lot of failures as I've seen are due to neglecting the oil especially at the very early mileage.

07 & 08 Denalis came with 6.2L L92 engines that did NOT have afm, except for a few built prior to April 1 2006 which had AFM hardware but it was disabled from the factory in their programming.

The GM TSB 10-06-01-008M that applies to most 07-14 TYE should have been done long ago: TSB 10-06-01-008M

99-00 5.3 pretty tuff.
