2007 350z stock about 39xxx miles 6-speed

I notice my car when I start it sounds like it is struggling before the engine actually turns. This recently just started. I checked my battery and the voltage is fine so I dont think its the battery. Any idea what else it could be that would make my car have a hard time starting?

thanks

 

Starter maybe? I know you checked the voltage, but you could try jumping it and see if it starts normal. If you're sure it's not the battery, take it into the dealer. Your 07 should still be under warranty right?

Coincidentally, my car was having a hard time starting this morning. Took it into the dealer today for service and they had the batter charged.

 

Mine was a bad battery. Just replaced it and it was fine. No harm in getting it tested at autozone or something.

 

Battery. Voltage may be fine but amperage is not when it's under load
