No direct sunlight...
It happens both with the top on and off... Also, the heat will continue to build up while the car is parked, before it actually cools off. The metal portion of the shifter eventually gets pretty hot and given enough time, so does the rest of the console and cup holders. My friend has a 325i which is also RWD and has none of these symptoms. Is this normal for this model or should I have it checked?
