Hello I have a question are the 2012 single cab 5.3l Chevrolet pretty good trucks I have right now with 197k miles it runs like a top I was wondering if their is any problems I need to watch out for with them and also if I could do tuning on them or upgrades if that’s even possible Thanks.
Yes. See our FAQ about cylinder deactivation.
As long as they're well taken care of, they can be alright. But I'd advise you don't get that truck at all! Ford F-150 with a V8, Nissan Titan, and Toyota Tundra are the best full size pickups out there if you'd like to get one of those three. But make sure it had been well taken care of first and/or take it to a mechanic. You wouldn't want to have to deal with a pile load of problems over a vehicle, it's not fun!
It’s ran like a top so far no issues at all I have one right now
