Hyundai dealer says battery is corroded but I see no evidence only a little black on top of battery?

Hi Janice,drive to Autozone,they will scan it for free and tell you why that light came on.It only takes a few minutes.

Fuel and spark circuits tend to be separate. A faulty crank and/or cam sensor will stop the spark and injection signal but unlikely, I think, that it will completely stop the fuel pump.

I am wondering if the immobiliser is disengaging?
A friend with a Kia once left his keys on the kitchen microwave with a similar effect. Fortunately the car was almost new and the dealer took pity on him and reprogrammed the system free of charge.

I suggest you check the fuses. There is sometimes several associated with engine management, fuel pump and suchlike.

Completely dead is usually:
a corroded battery cable near the connectors, -cut off corroded end & refasten or replace cable.
a loose or in adequately tightened terminal connector, -replace terminal or cable
bolt off starter motor, -replace or repair bolt.
battery plates out of alignment, -replace battery tray \, hold downs & battery.
A blown fuse is rarely the problem.
Good luck.

Replace the terminal the other wire is for the computer.

Start with the basics - I had a car with this exact problem an the solution was simple - corroded battery terminals. Try cleaning them first if that does not get it try to jump start it or check charge the battery as if the terminals were corroded then it may not have gotten good charge from the alternator. If still no joy then look towards starter motor / solenoid for starter.

wouldnt have thought so ,i would say a year on the battery tops but i could be wrong go and ask at the dealers

Yes you can have the battery replaced. This however needs to be done by an Authorized Service Dealer. To find your nearest dealer in the USA, use the online search function here:

If you are in another country, go to the top right of the screen, mouse over the Country and select your country. Look for a tab for the Authorized Service Dealer search function.

check the battery. if it has a little clear eye on top it should be green if it is black replace the battery.

Any overcharge situation can corrupt an ECM. Incorrect placement of jumper cables and not grounding properly can definitely damage an ECM (computer) However most people still jump cars like they did before computers.. red to red and black to black.. this is WRONG.. black shoudl be grounded on alternator or car frame. If you did this and didnt ground properly you very well may have corrupted or burnt ECM. If corrupted it may be "reprogrammable" by dealer also called "flashing" if you burned it then it will have to be replaced by dealer as it requires programming to specific VIN of your vehicle.

the battery is weak, and need replacement.But sometime your batt terminal is poor get it repair first.
