If none of that's true, the charging system could be a problem or the dealer may have gotten a bad batch of batteries and gave you one of them... rare but it happens.
It could also be a loose ground wire somewhere between battery and a hundred places. Or something more serious that the dealer needs to find.
Hmmm.. I do belive that I have a charging system problem... THat is what I told them when they replaced the battery.. but the computer said everything was fine..
they put the new battery in .. and all was well for a day.. but this afternoon with the A/C on the battery warning light came on again..
I am sure they will find something in the charging system is awry...
I too am betting that it turns out to be a loose ground..
Before they changed the battery I tested the charge voltage with the engine running at the battery and found it to be only about 12.6v.. (not enough to charge).. and I told the technician that... but he said the computer said it was OK...
I do think though.. that my not "knowing" how the car starts has added to the problem... I think that when it does not start every time that there is something terribly wrong... when in reality.. I am just not used to wating long enough for the starter to engage...
THat leads me to complain to the dealer that the car is not starting..
when in reality it would be fine if I had only waited a little longer..
the battery problem though.. that is a problem...
