My family has two G37 coupes (yes, we're spoiled )...I have one and my sister has one, they both happen to be at around 30k miles. In the past month, every other day or so, one of our car batteries would die...They're the '08 models.

Obviously one would think for a new battery, but, dont batteries usually last a minimum of 3-5 years? Or does it go by mileage?

What Im trying to see is... is it a coincidence that both the cars are having the same problems? or is there a problem with this line of G's with batteries? We're not leaving the lights on or anything, we leave it on auto.

For example, I was listening to music in my car after about 20 minutes of driving, the car was off and i was listening to music for 5 minutes...and the car wouldn't start.

Just wondering if I should just go ahead and get the new battery or is there another factor that should be assessed?

Thanks

 

just came back from parkway infiniti and they replaced my battery since it was doing the same thing...lotta threads out there about dead batteries, better get your free battery replacement ASAP!

 

Infiniti OEM batteries SUCK. I'm on my second one and now that the temps are dropping again it is starting to show signs of dieing again.

 

many threads, it's the batteries.

 

My oem battery went out after 18 months. I brought it in to Autozone to buy a new one and the guy working there asked if it was a Nissan battery? I said yea sure is, he's like yea im not going to bother testing it cause its more than likely toasted.....i was like yea, its dead haha. Apparently word on the street is Nissan batteries blow

 

Mine has been messing with me the last few weeks and then died the other day. Only had the car 18 months.

 

Nissan should send us all complimentary batteries!

 

go to the dealer you should get a new battery
i just got one on monday
i was having the same problem

 

another one bites the dust,, well two actually because you got two Gs hehehe
seriously though, these batteries are garbage. Funny thing is after they recharged my battery, i havent had any problems with it--- YET!

 

have had mine for 16 months and is starting to crank slow. i can see the same problem coming. i wont be buying a battery from infiniti thats for sure. i wont even take a free replacement one. i will get a good quality battery!

 

Taking mine in tomorrow I will let you know what they do.

 

Same here, I'm going to go with a Die Hard Platinum

 

Interstate is the supplier for our Infiniti Batteries.

 

replaced mine with a yellow top battery

 

Funny how I come across this thread now.

I was about to go gym earlier but I noticed my trunk not opening with the keyfob, thought it was the keyfob battery.

I tried to start the car and all lights were dim and car wouldnt start.

Now it's dead.

car is about 16 months old/17000 miles.

Is this a known problem?, as in considered by Nissan/Infiniti?

Going to give my dealer a call and see what happens.
