I get a lot of crazy messages on my darling Puntos display but this one is the best. Middle of winter, 0c, coolant level ok, first start. It says. Excessive radiator temp turn off car. Lol. Then the message goes away and we drive off and enjoy our day. Just in case this message indicates an underlying problem I would like the opinions of other Punto owners. Thanks.

First check your battery power, when its low it creates weird message cause of the low power..
Few weeks ago I had that problem too and after i replaced me battery the message disappeard
Good luck!
