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: 2016, 2018, 2019.

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 4 service bulletins or notices for the 2014 Kia Forte 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

“Driving down the highway and check engine light came on and dropped the cars speed down to 30 mph and was stuck on the highway and I called the KIA dealership that I got the car from and they cleared the code on the car and claimed they fixed it just for the car to go back into limp mode and now I’m stuck without a car and the dealership doesn’t want to fix it”

Should you keep driving it?

This page can't tell you that. 0 of 45 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.
