Software Problems of BMW 750

The vehicle has had a dead battery numerous times with dealership diagnosing rear trunk lock, then rear door hklmodule, then reencode vehicle,, battery replaced twice, was not retrofitted correctly, redone, continued to have dead battery requiring jump starting, submitted case #29008954 to replace vehicle, denied. Replaced dme and programmed vehicle, cas,lm and dme failed during programming. Reset battery and reprogrammed until passed test. On 8/23. 2011 again car would not start, jump started with transmission fault light on. . . Called BMW and they said to drive in to dealership. Driving on the freeway at 75mph, the vehicle jolted and faltered so calling I pulled over 6 lanes to side of fwy to call dealership that it was no longer safe to drive. They towed in. Diagnosed for 2-3 weeks and returned. Problem with dead battery has continued to this date where I keep a powerful battery charger in the car. It would not start on a public street so BMW said to drive in to dealership again and are now diagnosing. Initially called after 4 days to say it was a bad battery which is not the case as it is evidently an ongoing electrical or software malfunction draining the battery. I have requested this vehicle be purchased back by BMW or some resolution as I no longer trust or feel safe driving this vehicle. I am now waiting a response from the dealership.

The car, while driving, rebooted its internal systems and the car had a 2-second shut-down and greatly reduced speed and responsiveness. When the dashboard and middle console came functional again, it displayed several warnings that certain features (like dynamic drive) were shut off and the car needs to go to a dealership. This car has been plagued with "electronic" problems since its purchase and has been in the shop every two weeks with a system failing or shutting off. BMW has proposed many solutions but have yet to fix it, and after the last "fix" the car started to reboot itself and turn off safety features. The car has had a "version update" of the software but that has seemed to make matters worse. I have pictures of the on-display faults that were being displayed as well as a video recording of the system rebooting itself.
