Deliveries should be underway now, so I'm confident that this has already been resolved for anyone with one on order. Catching these kinds of problems early on goes a long way in helping to maintain sales and overall interest in a new model.
That can be said for any automaker in almost any SUV segment. Demand is through the roof!BMW is lucky because there in a position that this won't impact their sales.
People have wanted the X7 more than any other SUV yet. Similar to what can be seen from Mercedes and Audi.
Ultimately what matters is how BMW deals with issues like this.
