My FTM keeps alerting me that I have a flattire, when indeed I do not. Happened before and I was by the dealer so they checked the air and said it happens sometimes when it is cold. Happened again today, and yes it was cold, but I figured they would have designed a better monitor. Should I take it back to the dealer?

Yes, check the pressures and reset. Mine used to go off when one tire was as little as 3-5 psi lower than the rest. The system doesn't tell which tire unfortunately. And if on tire is bordeline low, then the cold weather can reduce the pressure (Yes, I did learn something in physics class!) enough to set it off...
