BuMp...could it be starter relay?

First and foremost, make sure your battery posts are clean and the battery terminals are tightly connected to the posts. You may also have a loose connection somewhere in the wiring going from the battery.

Turn your headlights on, and your interior dome light and try to start the car with them on, and pay attention to whether or not all those lights shut completely off when you try to crank the car. I've seen that happen before in cars with loose connections going to the battery. Normally when you turn the key, the lights would dim a bit instead of turn completely off.

This is what has been replaced in my G

Gas Tank
Window motors
Radio
Speakers
Climate Control panels
Transmission MT6

I have owned my G for about a year and a half. I am glad I have an extended warranty!!!

warranty all the way!
10 years and 100,000 miles!

im having starting problems as well but i just need a new battery

thanks for all the replies, much appreciation.

Do you have an aftermarket alarm?
Why did they replace the gas tank?

Damn.

I only had my Bose replaced because my cd's got stuck inside. And I'm going on 3 years soon.

have my coupe for 3 years never a problem, love it all day every day!

The meter stopped working so after replacing the sending control unit that fixed nothing they just replaced the whole system including the tank.

I'm so ****in pissed, it feels like I'm getting taken advantage of from Infiniti. I jump started the car and it works fine now. I'm going to the dealer and going to get my point across as much as I can, this is ****ing ridiculous, I payed those ****ing bastards $700 to ****in fix a radio? What a ****ing joke, I normally don't drop the F word this much but this is what it has come to. If these ****ers can't find the problem again then we have us a problem, one that I will have to deal with in a personal lawsuit against infiniti.

Dont ****ing gouge a customer 700 bucks for a repair and in a month down the road the car is having the same ****ing problem. What a ****ing joke, I'm so pissed. I deal with customers all day providing the utmost customer service and what do I get in RETURN. ****? **** infiniti.

PS: I love my g35, but sometimes it's a bitch.

end rant/

man for $700 I would have got a DD kit and a aftermarket headunit

yea I was thinking about that, but didn't feel like going thru the pain and hassle...
