I have noticed that if I am at idle and pull up on the door window buttons (two at a time) the engine will drop idle and you can not only see the RPM lower but feel/hear it as well; things go back to normal when you left off those switches.

Has anyone else experienced this?

 

I think this is somewhat normal. If it's really bad then you may have a charging system issue. The oem battery is garbage and is known to fail. The dealer usually checks the battery when getting an oil change or you can visit an Advanced Auto type auto parts store and they call run a diagnostic on the cars charging system in the parking lot for free.

 

That's alittle odd, I get a slight surge in rpm at idle when rolling up and down on windows, etc

 

Same issue going to have it a year next month considering getting a new battery to avoid future issues.

 

I think that's normal. The more load you put on an alternator, the more difficult it is to turn the alternator.

I think all my Maximas have done this.

 

Every car I have ever owned has done this

 

Thanks all. Dealer usually checks battery when I go for an OC (coupon of course) and it looks okay. It's a 2009 but has 143k so I am starting to look out for things but sounds like it could be normal.

 

At 5-6 years old your battery is pretty much on the downhill side of its life expectancy. Might not be a bad idea to keep an eye out for a new one. I usually change mine around that time so it doesn't leave me stranded somewhere.
