I too have the same problem with mine and it's only got 500 miles on it. There are no campaigns or recalls out on it but I may have to take it in for them to see the symptoms. Let me know if you find out anything. Does you passenger side headrest have a strap sewn on to the top of it? What is this for? Did your M come with a lug wrench for the tires? any info would be greatly appreciated.
