Odometer resets everytime I start the car?
 

This happens for about a month or so now. When I start up the car all the needle would go all the way to the end and back to normal just as you would see when you reset the battery.

Two days ago, the car failed to start up on the first crank, but that may be due to very cold weather.

Is this a sign of dying battery? This battery is about 4-5 years old.

Yep, your battery is going on you.

That's what I figure.. any quick recommendation? I was looking into Optima but I think there's fitment issue with our stangs.

its the battery. just get a stock replacement unless you just want to pay for the better looks of an optima

I forgot to mention that the needle indicator for battery life is normal (points a little above midpoint).

Thanks for all your help.

the needle is really reading the alt output unless the car is not running! i would get a new battery and test the alternator because bad alternator can kill a brand new battery in no time.

This means you got a good alternator, but a crappy battery.

Maybe testing the Battery and Alt first would be better than throwing money at it and not fixing the problem.

I'll do just that. The car only has 20k miles on it though.

Thanks for all your help again :icon_bunny:

before changing battery check out this post <click here> and scroll down to cliffys reply , i had the same issue and this took care of it. i checked all of my fuses when i did and found a bad one though cant say for sure it was the same one but it worked.
