Misfire on other Sonata years

Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2019, 2021, 2022, 2023, 2024.

What this problem usually is

These reports start with the check engine light. Many describe the engine running rough or shaking at idle, a P0300-series code, or a catalytic converter code. A worrying number say the light was flashing. Owners often list ignition coils or spark plugs already replaced, and the light coming back afterward.

Is this a known problem?

The manufacturer has sent NHTSA 9 service bulletins or notices for the 2014 Hyundai Sonata that deal with this problem. Newest first.

Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote

“I was driving at a higher rate of speed 50 MPH in the center of 3 laned road no warning or indicator lights were on in my vehicle when the engine without warning blew and stopped working. Again no check engine lights were on no warnings were given. It shut down and would no longer accelerate or drive. We almost caused several accidents as this was a very busy roadway.”

Filed Sep 19, 2024

“Extremely rough idle when stopped. Trying to accelerate to merge into traffic the my. Car had no power and I almost got creamed ! I had to pull over so other cars could go around me. Several other issues with car like oil every month or so. I had gas pouring from a hose on my engine and when I brought it to dealership they wanted 1100.00 knowing it was a recall. I hope the dealership and Hyundai rot. !”

Filed Aug 10, 2024

“I was driving on the freeway when the check engine turned on and was blinking. I pulled off the roadway as flames began coming from the hood of the car. The car became completely engulfed in flames within minutes. It was a total loss in a matter of 15-20 minutes.”

Filed Apr 8, 2024

“I was on the interstate and my engine started to sputter and the check engine light came on. I quickly decelerated from about 70 down to under 50. I was able to safely pull over to the shoulder and had to have my vehicle towed.”

Should you keep driving it?

This page can't tell you that. 1 of 65 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
