Since then I bought a CTek battery charger and have been using it regularly, the battery loses charge and hence voltage over time for sure. At a certain point it's going to cause issues with the car's electronics and imo it could explain the rear diff issue.
If the dealer doesn't replace the battery I'll probably just buy an Optima and charge it monthly with the CTek in hopes of it lasting longer.

These cars get really flaky when voltage is low. IMHO, the heat in Florida kills them pretty quick (i'm on my 3rd) and the car starts to exhibit random annoyances. I have a NOCO now that I will use on mine from time to time.
