Battery Cable problems of the 2007 BMW 328

My car shuts off unexpectedly with total loss of power can not use remote to unlock car doors while stuck inside the remote key will not release from car the car was running went a few miles came home and car just shut down electrically with me inside . . . Had to call from my cell phone that I could not get out of the car reports state this can be from a recall on certain models due to the battery cable connector and fuse box degrade over time I am hearing impaired so email communication is best.

I was leaving my place of employment when the vehicle cut out with no electrical power and the engine died. It restarted and I went home. The next morning the vehicle had no power and would not start. Upon investigation, the battery in the trunk had 12. 60 volts and the fuses at the power distribution center/box had only 2. 80 volts. With a screw driver I moved the large red battery cable going to the back of the pdc and all the lights came on. I subseqeuntly removed the pdc and inspected the main power lead. The terminal was corroded has a relatively loose fit and just clips to the back of the pdc, even though it is a large gauge wire.

In June of 2011 my Bmw328i had intermittent start. I sent the vehicle to a dealer for service in fremont. I was told that the vehicle did not start because of the battery. Battery was replaced at this time. Two days later, the vehicle did not start again, after testing it was determined by fremont dealer that the problem was a faulty negative battery cable. After cable replacement, today problem occurs again.

In October of 2009 my leased vehicle did not start, I had the vehicle towed to a dealer for service in detroit. I was told that the vehicle did not start because of the battery. Battery was replaced at this time. In January of 2010 the vehicle did not start again, after testing it was determined that the steering column was defective. This was replaced at my expense. In April of 2010 the vehicle did not start for a third time. I contacted a dealer to have the vehicle towed in; after 5 days the dealer identified the problem as a faulty negative battery cable. I contacted BMW na as I felt that this may have been the original issue and reason for the vehicle not starting. After two weeks of "investigation" BMW na contacted me and stated that due to mileage on the vehicle no assistance would be granted the vehicle is still under lease and was sold to me as a demo vehicle with roughly 9000 miles already on it at time of lease inception.
