My 2 week old 500's mileage started flashing today. Have read the stuff about getting it re synchronized. Does anyone know if the same fault could cause the backlights on the heater controls to go off. There are 4 dials and 2 had backlights and 2 didn't , it being new i just assumed this was correct, until they miraculously came on again!! Having had an alfa before with lots of quirky electrical problems I wasn't too concerned. Mind you that did end up with a major electrical failure in flames on the M4 so maybe I should get things sorted!! Hopefully the fiat mechanics will be better than my other garage as their usual answer was if its not happening at the time they can't fix it! Oh well back to spending hours at the dealers.
