NSX2NV

So long story short my buddy tried to jump start a car with mine and reversed the polarity. Since then my heated seats won't work sometimes and to make them work when they actually do I have to turn on the passenger side then the drivers side. They will work for about 10 minutes then shut off. Also I the "Check Fuel Cap" red light turns on saying the cap is loose even when the cap is on tight. That happens a few times a week. Does anyone know what I can do to try and fix this?

Thank You,

Ty
