I love my car, but there is a definite design defect. The electronic module that controls most of the electronics in the car is located under the tire well in the truck. It's very easy for liquids to seep into the compartment and cause an "electronic malfunction". I was carrying groceries in my trunk and some liquid spilled. Before I made it home, my car's electronic system went haywire. I took it to the dealer and explained my problem and he new exactly what it was. It seems many other car owners have had the same problem. At a cost of $790 they repaired the problem and relocated the electronic module. It seems this is an ongoing problem and BMW should have made owners aware of the issue
I had a leaky trunk seal and during a rainy day discovered my car wouldn't start.
Water had gotten into the modules.
Very expensive repair.
Under warranty, but the car was out of service for days.
The 6-series apparently had a recall for the trunk seal issue but not the 5.
