Why does my Sonata’s check engine light come on when I start it?

It’s usually normal for your check engine light to turn on upon ignition. This is just your Sonata testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.

Are Hyundai Sonata engine noises bad?

Unusual noises can signal a problem with your Hyundai Sonata engine. Tapping or knocking could mean you're low on oil. Whistling sounds could mean you have an intake leak or misaligned belt. Squealing can indicate a loose fan belt, and grinding could be a sign that something is wrong with your brakes — not the engine.

Some driving habits are not so great for your engine.

Can I add water to my Hyundai Sonata radiator?

An emergency is the only time you should consider putting water in your radiator. Outside of that, it’s recommended you use a pre-mixed coolant or a 50/50 blend of water and coolant. However, if you need to continue driving your Sonata when you’re out of coolant, having water in the coolant reservoir is better than nothing.

What could cause my Sonata engine to suddenly stop?

If your Sonata car engine suddenly stops, it could be due to overheating, low fuel, a faulty ignition system, sensor problems, electrical system trouble, or mechanical issues.
