Battery replacement I have a 2005 Santa Fe. It had a hard time turning over this AM. How long should the battery last...when is / if it needs to be replaced? Thanks, John in Florida

Very unlikely. Everything works from cylinder number 1 being at TDC on firing stroke. Crankshaft position sensor and Camshaft position sensor have to be in synch.

If you have had the battery disconnected for working on it, there is a relearning process that takes a while.

try your local dealer

there is a site I heard of (free radio codes) but you need the code off back of radio ,check out site and see if you can get directions on how to.

check your battery first, if not replace your starter.

New replacement ends, available at auto parts stores, are a simple bolt-on repair. They are not noted for quality repair, but they do work if properly installed. The best fix is to replace the entire cable. Hope this helps!

You have an internal security code in the radio. You need to put that code in. If you don't have it, contact your dealer.

check the crank sensor

I had the same problem. Even If I left the cab light on while gassing up(with the car shut off), my battery would die.


Two things.Purchase voltage meter ($20 - $25) to test your battery output. It should read from 12 to 12.8 volts. Anything close to 10 amps or less, you should replace your battery. You can also run this check with an amp meter with cab probably be even cheaper. Another option is a battery charger with a built in amp meter. Just disconnect the cables and connect the battery charger. When you plug the charger into the wall it will should you a proper amp reading. Again, if it shows too low a reading you need a new battery. This comes from experience as I have a 2005 Santa Fe with the same problem.

The second thing is to take your vehicle to have the alternator checked. With older vehicles we used to start the car and disconnect the negative battery cable.( If you do this, DO NOT let the cable touch anything.Just hold it in your hand.) If the cars shuts off, the alternator isn't charging the battery properly.

*** NOTE*** I'm not sure if this is recommended for newer vehicles but it was an easy fix for older vehicles, a time and money saver for sure.

Good Luck.
