Hope it's the first and last issue you have. Unlikely but swapping to another car won't make any difference as virtually BMWs have unique quirks; give them a chance to remedy this one first. I bought my 328 convertible used with a smidge over 10K miles; it had a ton of issues but with the help of this and other forums it's virtually trouble free now.
