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. |
