Even a 1 day repair means 440 miles and many hours. Called BMW Recall Hotline at [XXX] & explained my situation. They declined help saying the dealer decides how the repair is handled. I called BMW Customer Service [XXX] . They declined help & said a BMW dealer must repair unless it wants to work with another repair facility. I submitted a web-form…”
