a group complaint will need to be very specific, a few people with gearbox complaints unless proven to be identical will be denied, personally i would like to see BMW reduce not only their service intervals [ not just BMW ] but also add service intervals for autobox's, manual box's and diff's etc, sadly though i dont think there is enough vehicles with major problems to make BMW sit up, realistically for every one with an issue there are thousands that have no issues at least within warranty periods anyway, sometimes in life we are in for a beating without recourse and all we can do as consumers is try and help each other, big buisness doesnt care.
i used to work in a technical dept of a big breakdown organisation, we would be sent technical service bulletins from various makers and give feedback on roadside repair possibilities or even prevention solutions, i learned early on the only makers that gave a damn were Japanese and Korean and even then only up to a point. so really unless there are big numbers involved plus media/news outlets then we dont have much of a hope apart from forums like this where we can put our heads together .....B
P.S sorry to sound like a defeatist, but it is what it is
