Mine is one of them. I've been through two O2 sensors so far since the coolant its burning is fouling the sensors. The first two times I took my truck in, they replaced the sensors but swore there was nothing wrong with the engine. Finally on the 3rd try they took it apart and found that the intercooler was leaking like a sieve (sp?).
Anyway, part is backordered for another month. :-(
Other than that and the suspension clunk in the front end, the truck has performed flawlessly.
