At 10 months old and 26K miles I got a low coolant warning. I took it in and the dealer said it was the TSB about the air not being purged from the factory. They topped it off and sent me on my way. I marked the tank with a sharpie at cold level at that time. 6 months later I noticed the coolant level has dropped 2"-3", so I took it back in. Dealer said they pressure tested it overnight and there was no drop (no leak). My only thought is if they hooked up the pressure testing device to the top of the reservoir by removing the top cap then maybe my issue is my cap. (Side note...there is also a cap on the side of the tank I just found out about).
Thoughts???
