Driver's seating material separated. Not punctured, but separated. Bottom seat cover replaced. Auto transmission shifting too erratically and frequently for no reason. Software update appears to have corrected the problem. Vehicle was "lurching" forward when coming to a complete stop as transmission shifted back into first gear. Told there was a software update for this. Apparently corrected problem. Pronounced accelerator lag from stop. Software update makes significant improvement, but issue still present to a minor degree. My next MB will be a manual shift though. Cell phone bluetooth integration provided echoing and unusable voice response during calls. While I noticed problem, was advised there was a TSB/software update for this. Seems to have corrected problem.
