Why is my Hyundai’s check engine light on?
My Hyundai’s check engine light is on. I don’t really know much about cars, and I don’t have time to dive into it. I need this fix, like now. Can someone tell me why my brand new Hyundai would have the check engine light come on all of the sudden?

Great question! I’m sorry to hear that you’ve got a check engine light! Unfortunately, there are literally hundreds of reasons why your
Hyundai’s
check engine light might be on. Most often, the light is caused by a gas cap that isn’t on all the way or a faulty O2 sensor. Try tightening your gas cap. The light may turn right off. If that doesn’t fix things, you may need to get an OBDII scanner and check what the exact engine code is. That will tell you the source of the problem. Of course, you can always have a mechanic check for you, too.
Some of the most common causes of the check engine light (besides the gas cap or O2 sensor) include:
- Failing catalytic converter
- Faulty spark plugs or spark plug wires
- Faulty mass air flow sensor
Once you’ve got the check engine light resolved, take a couple of minutes and save yourself hundreds on your
