Sorry! While there are many, happy E70 owners on our board with little or no problems, there are quite a few that have had/or are still having consistent problems. The E70 (for a lot of owners worldwide) is plagued with numerous electrical problems, and in regards to the water in the rear door jamb, design faults. I had a 2007 3.0si (worst car of my life besides my Range Rover) and the 2008 4.8i isn't much better. Sadly, it seems that a lot of these problems will never go away, and as the car (and computer systems) age, you can only expect them to worsen, and new ones to arise. You have 2 choices with the E70...learn to just live with all the problems and develop a great relationship with the Service Dept., or cut your losses and get another vehicle. The MBZ ML, Audi Q7 and Lexus RX are all great alternatives, which have proven to be more reliable than the X5. They might not look as "hot" as the X5, but reliability and peace of mind are much, much more imporant IMO! Good Luck!
