I had this car built and I am the only owner and driver. I have had a personal mechanic take meticulous care of it over the years and the car is stored for approximately 6 months/year because I do not drive it in the snow, and frankly, hardly drive it even when raining. However, it never fails that each year some warning light goes on for no apparent reason. Last fall it was the ABS light and the brake light. My mechanic put the car on the computer, and found no issues. Now again, this spring it started out as not being on, but within 5- 25 minutes (varies each time when I start the car up and drive) those two lights come on. Every year there seems to be new lights that come on for no apparent reason. I haven't driven the car more than a few times before a light comes on. It's cost me so much in diagnostic time. Also another problem is that often the radio doesn't turn on. When this happens, the screen also does not pop up. I have to stop the car, turn it off and then restart. Most times the electrical system seems to 'restart' itself so that the radio turns on and the screen pops up. The electrical system in this car has never been right.

GM5 module fail. When the GM5 module fauls windshield wipers won't work (this could be a big problem if it rains!), interior lights won't work, windows won't go up or down, no alarm functions and of course no automatic door lock control (doors can manually be locked and unlocked as long as the double lock is open.)

I left my BMW in the sun all day and now my locks wont work. Many resources link this problem to the GM5 which controls the lighting and locks. Bad locks can be a safety and security issue on parked cars but also for moving cars as children may open vehicle doors in traffic.

My BMW Z4 which is still under warranty has defective headlights and the dealer refuses to repair them. BMW used an inferior type of plastic which is clouding over and preventing the headlights from working correctly. Please recall these vehicles so that BMW will repair the lights and make it safe to drive at night again.
