My '08 4.8i had it's fair share of battery issues (as did our Z8 Alpina). I just find it totally ridiculous, that with a car that costs ($50-100,000 for X5 models or $140,000 for the Alpina)...that BMW can look a customer in the face and say "put it on a charger" at night.

While we have had several Mercedes and Range Rovers that had their fair share of unique problems...NEVER once did we need to worry about battery chargers. Even my old 1983 300TD with 193,000 miles (that got driven maybe once a week to the Supermarket or Home Depot) never needed a battery charger.

Considering a great deal on a new X6 5.0i. Wondering if all these X5 "goodies" happen to the X6 as well!!
