I have a '11 accord SE that is giving me fits. It will intermittently decide not to start unless it is jumped off or hooked to a charger. I know it sounds like a battery problem but the battery has been replaced already and the new one checks good. When it does this it acts like the battery is very weak and the engine will not catch. I can hook the charger to it for about a minute or so and it will fire right up. My wife started the car at 4:30 in the morning to make sure it would start and it started fine. When she went to leave for work at 5:30 no such luck. After she put it on the charger it started up and she went to work. 8 hours later she gets in the car to come home and it acts normal. I am at my wits end. I have not been able to find anything on the '11 model about this like I have on the older models. I keep seeing the main relay being a problem on the older ones but I can not find any information about that relay for mine. Could that be the issue or should I start looking somewhere else? Any help or advice would be greatly appreciated.

 

2011... take it to the dealer.

 

It is out of warranty. We have logged 57k miles on it since we bought it and this issue has just started to rear its ugly head. I hate to take it to a dealer and have them fix something that I could have possibly done.

 

do a voltage drop test on both neg and + battery cable
