Hi, just joined ... own a 2003 G35 Coupe, silver, 6 speed....nice car....I have some questions about some repair items needed with the car and was hoping to get someone else's input. My circuit board that controls my radio and air conditioning speeds is intermittently spazzing out. My dealer tellsl me it's like a $750 repair job.....my local mechanic tells me that he is seeing alot of that with other cars and is suspicious that it should be a recall item.....is Infiniti HQ any help on this?
