The headlights and Interior lights will get really bright while driving and then go back to normal, it does this a lot. And now the check engine light is coming on. Would love to know what the problem may be.

have the charge system tested, it sounds like the alternator is intermittently overcharging slightly. Is the SRS light on as well ???

Thanks for the response, there are no other lights on except the check engine light, and it only comes on occasionally. I took the car to O'Reily's auto parts and had them test the battery and alternator with there handheld tester, and they said they both checked out fine. So I changed the terminal ends. The battery is the original battery, and has almost 98,000 miles on it, but the parts store said it was ok. Do you think it could be the battery.

since the CEL was on, there most likely may be a code stored in the ECM memory. Best is to have a HYUNDAI tech scan the ECM. You don't want to wait till the system overcharge too much for a longer periode. I had one case, were the alt. charged 87 volt. needles to say, it blew EVERYTING, which was operating/switched on at the time.
