Like The Title Says I Have My Coupe For About Two Years Now And Within The Last 6 Months My Battery Has Died On Me Twice And Dont Have Any Ideas Why

 

Get the battery and alternator checked.

 

Is this a daily driver??? Crazy sound system???

 

bad starter.... sounds weird but mine did it for like a year, ten it got bad enough i had to get jumped off everytime....so i changed the battery, checked alt, and still same ****...but then i changed the starter and problem went away

 

get a new one ;D

 

the battery is new maybe two months old if that and dealer checked starter and alt first time it happen and told me there was nothing wrong with them
and yeah its a daily driver but only 5 miles a day

 

do you have any aftermarket stereo eq? if so make sure you have it wired to acc to turn on and not a constant

 

Start by making shore the Battery Terminals are clean and tight.

 

I can't help you, but if i leave my radio on(alt) after shutting the car down my battery will die.

In my case i think i need a new battery, but i am fine being surprised that my car starts everyday

 

My car is garaged and when I first got the car, I've drained my battery on a few occasions by leaving my keys in the ignition (even if in the off position)...

 

I had the same problem (I have a 2003 G35 6MT Coupe)...battery died in 2007 so I had it replaced (DieHard from Sears). However it died again maybe a few weeks later. Both times the car had been in the garage and undriven for a few days or a week. When it died again I took it to the Infiniti dealer and found that it had a parasitic draw in the radio system. If was replaced (incorrectly the first time..apparently Infiniti doesn't know that the sedan and coupe use different mother boards..go figure!) One last note...the battery from Sears was a dud as well...so had to replace that TOO...so your best bet is to just let Infiniti replace the battery if need be...a few extra pennies are always worth the peace of mind

 

thanks for all the feed back took it to infiniti and there looking into the problem right now
