Had this happen 3 months ago and the battery was dead so I replaced it and now it is happening again, but the battery is good
Are you certain that the battery is good? Make sure that there's nothing in the car that's drawing additional power, such as leaving the headlights or radio or other accessories on when the engine is not running.
If everything else seems good, then it's possible that the alternator has gone bad. The alternator is what charges the battery while the engine is running, and if the battery isn't charging that could be why it gets weak. Your car is a 2010 car though, still quite new, so it's unlikely that the alternator goes bad this quickly. If your car is still covered under warranty, you might want to take this in for a mechanic to check.

Clean out the Idle Control valve. remove the air duct from the aircleaner system. spray directly into the valve opening. it is a small component with 2 small hoses . Sludge build up and oil deposits will dirty the valve. If that does not work you can remove it and spray directly into the 2 holes on the underside of the valve. Clean the air filter or replace it.if that is not it, then it is probably the EGR valve.

Hi. this is defiantly a slow or major drain that is occurring within this vehicle. Here is a test that you can preform that will help you find this battery drain so you can illuminate this issue.
--BATTERY DRAINAGE TEST PROCEDURE--
Using a 12-volt test light, hook one end to the negative battery post the other
end to the negative battery cable you just disconnected. The test light will glow
or "light" if there is a drain. If the "light or glow" is faint, that is probably
normal draw for the clock or computer. If the "light or glow" is bright, then there
is a large drain. That should be corrected. Now start removing and replacing the
fuses one by one until the light goes out; that one will be the circuit with the
drain. Remember to hold in the button in the door jam for the interior lights.
Please rate and god bless:)

Make sure by having them tested. The battery and alternator. Autozone should do it for free. Basic tests is all they do. but it might show something.

I was told by a loca mechanic that Nissa has had problems with electrical grounding for some time. Ii had a 1997 Altima that I intened to drive forever but finally gave up at (only) 90,000 miles. It went through 4 alternators in three years. Also a corroded radiator. The mechanic said Nissan has used the engine block as a ground, since cards today don't have the old-fashioned frame rails. Any loosening or other disturbance to that engine block ground will cause electriclaly-charged coolant to flow throughout the system: definition of elctrolysis. I don't if this applies to 2000-and-beyond vehicles, but it did in the 90s. Elsewhere in this section someone posted a ground solution (Maxima) that looks good. These are great vehicles, but if you have one (any make) with a persistent electrical glitch it can be one of the most frustrating and costly problems to fix.
