For the past several months I have not needed to raise the roof as the weather has been great. I have had several little things I try to ignore: the radio volume control does not respond properly when adjusting the volume (I did take it apart and clean the 'sealed' pot which worked great for @ 3 months). I have had an initial dsc warning at startup that will go away if I shut down and restart. The steering column started doing the jittery movement up or down. That's it...so I put the top up since it was 45(f) and proceeded to notice that all of the above issues were non existent. I have driven it for 5 days since and they still have not reappeared but I expect to lower the top this weekend, who knows what will occur, I love this car.
