Only happens about once every 2 wks, car acts like needs a battery but the battery checks out fine.
Out of the blue when i start my toyota 4 runner it acts like the battery may need to be replaced. I had the battery checked and they tell me its fine. This happened about 6 months ago a few times then stopped. Now It happenes about once or twice every 2 weeks. Could it be my alternator, and if so how do I get it checked?
