I love GMC trucks since I saw Lethal Weapon 2 when I was 16. I was hooked. Even went to as far as to recreate the 89 dually from the movie and always had them throughout the years. When the redesigned body style came out in 2014. I was in love. It was awesome they brought back the GMC logo back on the middle of the tailgate and I love the front end with the LED headlights. But never purchased one because of the bad reviews and the problems with the transmissions and the motors with AFM. After my son got one and I drove his, I'm ready to get one.

Thank you very much for your input. If I end up buying it I know the risk I will be taking. Thanks again.

Thanks. I think I can purchase it for $9,000.

So what you're saying is, AFM doesn't worry you guys with this motor and they are still half decent? Thanks.

I understand that but I'm talking about active fuel management on these motors. That is the ticking time bomb. What's the most milage some put on a 5.3 with AFM?

So that motor is that much of a tickling time bomb?

Hey guys Might be able to get a great deal on a 2014 GMC Sierra 1500 SLT Z71 with a 5.3 with 220,000 miles on it. Truck is mint besides the high mileage. If this was a first generation LS motor I wouldn't even blink about purchasing the truck. But with that active fuel management and lifters and cam going bad. I am very skeptical. Trans was replaced about 30,000 miles ago and supposedly the mechanic turned off active fuel management at that time with 190K on the truck. It's the original motor. Should I stay clear of the truck? 3 months ago my son bought a 2014 GMC Sierra 1500 SLT with 112,000 mi on it. The transmission was just replaced at the time of purchase. 3 months later the lifters and can went on the motor. Thanks, Ted
