My dash board sometimes gives me a 'battery failure' notification, but not all the time.
I have replaced the battery twice and recently replaced the alternator and had the voltage regulator (part of the alternator) checked to see if it tightly screwed.
Anybody have a similar issue and how can it be fixed?

I recently got this Charging System Failure and brought my car to the dealer...they said it was this radiator sensor that failed. I understand that this can also cause your battery to fail. So far so good with this repair.
