Replaced the battery (under original warranty) and the issue went away... for a few weeks. When the error message reappeared I took the car back and the SA told me the issue was now being caused by over voltage. More specifically, when they replaced the battery, they did not register it properly in the car computer and that is why it was sending higher voltage. They registered the battery, reset the codes and told me I was all set. 3 weeks later (this past weekend) the error message came back on! I dropped the car off at the dealership this morning and just got a call from the SA, stating that there's an issue with the wiring in the center console and that it will take a few days to fix. I don't even know what to expect at this point. Will keep you guys posted on progress.

Quick update - just received a call from the SA. He indicated that they found nothing wrong with the center console wiring which led them to believe that the issue was caused by a faulty control module so they just replaced the control module. The problem should be resolved now but we'll see when i pick up the car later today. The interesting thing is that this time around the SA said he wasn't sure why the car was producing under and subsequently over voltage messages and that his best guess is the faulty control module was to blame. This makes me nervous because the last time i spoke with him he indicated the battery was to blame for both the under and over voltages. Needless to say, I've lost all confidence in those guys.

What do you guys think - should i take the car to another service dept and have them inspect the whole under/over volgate issue? I haven't had any other error messages come up apart from the parking brake malfunction so assuming the parking brake issue is resolved should i just assume the under / over voltage issue has been resolved as well?

Any suggestions will be much appreciated! Thanks.
