Our 2011 X3 had its first leak in February after a winter thaw. Water was dripping from the driver side blue tooth mic and the liner around it was damp. Brought it into the dealership but the problem couldn't be reproduced.
We have had the same leak happen 4 times since. It doesn't happen every rainfall but it seems to happen when it is raining steadily for a period of time. Our driveway is also sloped from the house and we back the vehicle in; we think it may be worse on this angle because of how the water drains. The drain tubes have been cleared multiple times with compressed air, visualized with a scope, and the vehicle has been through the dealer car wash and pressure washed many times. They even lifted the back tires to reproduce the driveway slope! There seems to be no drain hose disconnections or clogs and the leak has never been reproduced by the dealership.
The last visit the dealer thought it had something to do with how the rubber flap that covers the sunroof track was positioned. However it leaked again today; this time water coming in through the driver side light/sunroof controls. We have expressed our frustration to the dealership and to BMW Canada. The dealer at least gave us a loaner this time after an angry e-mail was sent to the service manager.
We are going to tell them that we don't want it back it it's not fixed. Wish we had a lemon law in Canada.
After multiple internet searches we see that leaky sunroofs are a common BMW problem that seems to have no fix due to a design flaw.
Our sound system stopped working last week too out of the blue. It still has power but no sound; (blue tooth, navigation, radio, etc.) We have tried resetting it but no effect. Days after that happened, we began getting a message that the battery was discharged and electrical equipment was shut down. This message appears after the vehicle has sat overnight. Had it into the dealer yesterday who replaced the battery but still no sound!
I could really use some good news stories right now of people who have had a similar roof leak and/or audio problem and had a successful fix; PLEASE SHARE!
This is our first new car and our first BMW. Although we love the vehicle, we are starting to regret our choice.
