Car Stall problems of the 2012 BMW 750

Rough idle,stalls at stops, shaking. Every time vehicle is taken into BMW of ontario for one problem it comes back with a different issue, I believe BMW of ontario is purposely damaging items on my vehicle that isn't covered under warranty so I'll pay them out of pocket.

Dealer reported that moisture entered a waterproof enclosure that houses the brake modulator. Water entered thru a drain hole from the cowl and bypassed a plate meant to keep water out. Once effected by moisture the modulator shut down all functions of the car including the engine while moving. BMW blamed it on partial submersion of the modulator but car was never effected by water/submersion and the dealer agreed that their was no evidence of that and could not find anything to support that condition. Upon repair dealer went to great lengths to try and seal compartment and install diverter that was replaced in the repair to prevent reoccurrence. This is a very dangerous condition that appears to be a manufacturing defect in manufacture on a very limited number of cars made by BMW for this specific model. Owners need to know that the conditions experienced have a much different effect on safety due to the hybrid design than a standard non hybrid car.

When entering the on ramp to merge onto the highway. I accelerated to merge into traffic and car vibrated violently and would not accelerate. I continued to press the accelerator but nothing happened and a message appeared on the display. Now, I'm stuck between the on ramp and the highway with a tractor trailer rapidly approaching. He barely has enough space to merge to his left and avoids rear ending me. This could have been catastrophic. I continued to press the accelerator and nothing happened. I put my hazards on and quickly read the message. It read, "maximum engine output not available. " so, I turned the car off and restarted it, and it worked fine for a few hundred feet until I tried to accelerate. It did the exact same thing but this time it allowed me to creep along at 35 mph. I pulled over into the emergency lane and turned it off and on again, and it worked as normal. But this time I just continued to drive to work at 35 mph. During work, I scheduled a service appointment the next day. After work, I pulled out of my parking space and something popped and once again it stalled. After turning it on and off again, I was able to drive it home. The next day at the dealership, I was informed of the customer care package (recall). But what I didn't know at that time, the car had already been recalled with the previous owner. A lot of the same work was duplicated. Btw, this is a 2012 750li with 37,000 at the time of the second occurrence. The first occurrence happened at 29,931. It happened again 2 months later. This vehicle is unpredictable and you don't know when it will stall on you. The last repair reduced the powertrain output and takes a deep gasp before accelerating. Please read BMW's customer care service. The number of repairs are too numerous to list on the remainder of this thread.
