Took the car in for a "free" oil change that the dealer sent a coupon for...got to upgrade to Mobil1 for $20 bucks...sold
Picked it up and they said the coolant bottle was empty. But wouldn't tell me why. I thought they were full of it...didn't see any coolant on the ground and it wasn't running hot. Got home and opened the hood...smell coolant over the left fender.
Came to search on here....TSB for a cross threaded oil cooler fitting in the block.
Took it back to the dealer the next day....fixed now. So the same issue they had from 2010...still happening in 2013.
Check your coolant bottles and sniff around/over the left fender!
