Engine Shut Off Without Warning Problems of BMW Z4

My BMW Z4 2011 stalled for the third time. This happened in a parking lot as my car was slowing down. The engine shut down completely and I had no power steering. I took my vehicle into the dealership the next day for service and contacted BMW USA. I purchased and installed a dash camera and captured the stalling on the third incident and provided them the footage. BMW USA did a visual inspection and claimed that my after-market led light bulb in my daytime running lights was the cause of my stalling without providing any documentation or testing. Based on their conclusions, they voided my electrical and powertrain warranty and denied any repairs to be made by any BMW dealership per BMW USA. There is a definite issue with this vehicle stalling that BMW cannot resolve and they have resorted to blaming the consumer without proper testing or documentation.
