    Hi guys, I just changed my Tucson ix35 car battery today from the stock to Motolite 2SM Excel.
    Now Im not sure if its related or coincidence but it only lit up after I changed my car's battery.
    Should I be worried? Should I send it off to hyundai for checkup?

    Try to reset your ecu. Usually after batteries are changed, the ecu should be reset. Turn your key to on position for 10-15 seconds then back to off postion. do this 3 times then remove key then start car. If this doesn't do the trick then have an OBD check.

Malfunction Indicator lighting up after battery change?
