Mein Auto: BMW 646CI
Voltage Issue

Hey guys,

I have a strange issue going on with my car.. When I initially start the car, after about 5 minutes of driving , I start getting a lot of error messages. ABS, dynamic drive, steering, and the transmission error. The car doesn't shift gears and if I press the gas the air or heat will stop blowing.. After a few restarts the car runs ok with no errors..
The car is a 2004 bmw 645 ci convertible. I do have an off brand battery; I had the battery and alternator tested at Auto Zone and they checked out ok. I never had the battery registered, not sure if registering the battery matters. Also the alternator has been changed with one from Auto zone. Do you guys have any ideas or insight that could help me with this issue?

Thanks in advance
