I have had my Rallye for a little over a week now and although I love the way the car drives, it has a lot of minor quarks that bother me. One of them is that when I have the fan/heater on for about 30 minutes. I notice a burning smell coming from the vents. When I shut the fan off, the smell goes away. I thought that since the car was new, it was just the fan running for the first time but now I have about 300 miles on the car and it still does the same thing. Any ideas or should I just bring it back to the dealer ?
