I learned yesterday that going forward, the 5.3L engine option will not have the DFM/AFM feature due to the chip shortage. I read the GM bulletin while at the dealership. It claimed a loss of 1mpg due to this deletion. Frankly, I consider this a good thing. Seems to me, one less thing to possibly go wrong over time.
I could have left with a 6.2l yesterday, they had 2 equipped as I want, but opted to order a 5.3l instead. The 10spd transmission has given new life to this power plant IMO. I’d driven Tahoe’s at work with 5.3l for years, our fleet never had a single issue with that engine.
Also due to the shortage, no safety pack option. Again, for me no big deal. Wife’s SUV has more alerts than I can stand!
I welcome comments or opposing point of views.
