Mine came on once on my 07 SE and it was because I didn't twist the gas cap on where it clicks 3 or more times. I have a 2011 Pro4x with 3k miles and no issues yet.
i'm that buddy,My buddy just got his 11 back from the dealer. The spark plugs weren't gaped properly
I would bet the dealer would never ever give you a new truck.^^^
Plus, you could have one of those sucks stuck in the intake manifold waiting to clog a valve.lol Seriously though, take that truck and exchange it. pro4alberta is right something pops up down the road don't think for a second the stealership will try to shaft you. 99% of the beauty of buying new is starting with a clean slate. Unacceptable!
Good luck man, hope all goes good, my truck has been running great since they fixed the filter and the sensor, feels alot more powerful too, well considering my engine is getting clean air now lolwell....you're right....my light came back on today.
will be taking the truck back to the dealer on friday....this will be take 2.
