Mine still runs great. Though, I don't know about anything before I got it, 207xxx miles were put on it before I got it. To my knowledge, my truck hasn't given me any problems. Though, for me, when it sits overnight and I start it, it always squeels a bit for a couple minutes, then goes away after the motor warms up. I think it's this damp/humid weather as well as the coldness added to it that I'm in.
