I have a 2006 Toyota Rav4 - The other day, the car wouldn't start. We jumped the battery and it started right up. No lights were left on and nothing is plugged in that would be causing this. I took it to the dealership and they said the battery was fine. Every morning it struggles to start, but eventually starts up. The dealership said it may be because I don't drive it far enough daily - However, I drive the car every day and I don't think that is the problem.
Does this sound like an issue with the alternator or starter - or does it just sound like the battery is bad - but was charged after jumping it and gave false results?
