Absolutely. One has to keep on top of the condition of the cars battery.
If I were you I'd regularly, as in daily, measure the voltage of the battery and at the same time of day. With the age of these cars now the alternator may be showing signs of dying. As an example. My beloved is250's alternator packed up at around the 85k mile mark. And my car had a 100% dealer service history. Just a thought.
