I bought a new battery in March 07.

Here we are now, Nov 08, and the car has been having a hard time starting sometimes, and sometimes it fires right up. I was thinking, maybe the starter, maybe the battery. My wife went to use the car a couple of weeks ago and didn't realize it was on and tried to start it, so thats why I am thinking the starter may have been damaged.

Took the battery to Advanced and they checked it, and the battery tested bad, so I got a new one under warranty. That in itself, is a bit concerning because why did the battery go bad after just a 18 months after being installed....hoping it is because of manufacturer defect.

Put in the new battery, and the car would not start for nothing. FINALLY got it started, drove for a few minutes, came home and parked it, then tried starting it 10 times in a row, and each time, no issue.


Starter bad?


I still have a check engine light on, but nobody knows what the code means, not even the Infiniti dealers. I think its an O2 sensor because its related to emissions, and it comes and goes.


Thoughts please.
