Engine

57 reports2 crashes1 fire
“Recently, while my boyfriend was driving my vehicle, the engine suddenly lost power without warning. He had the accelerator pedal fully depressed, yet the vehicle would barely move. He was fortunate to safely maneuver the vehicle off the road. Upon inspection, he discovered there was no oil present in the engine. Critically, neither the low oil warning light nor the check engine light had illuminated prior to this failure, providing absolutely no warning of a severe mechanical problem. After adding oil and performing a proper oil change, the engine began violently shuddering and shaking upon startup, and only then did the check engine light illuminate. The vehicle was immediately towed to an authorized Kia dealership, where I was informed that the timing chain had failed.”

Air bags

16 reports8 crashes1 related recall
“The engine went out in the middle of a busy highway road leading to a dangerous situation that I almost lost my life the vehicle was purchased in 2021. There shouldn’t be no reason that the engine should have went out that quickly when maintenance was kept up not only that there was an airbag defected issue, which is a safety hazard as well. It was the most scariest situation ever when the engine shut off in the middle of the road. Also, there was many concerns of my vehicle being reported of also being almost stolen by Kia boys I have a report on that.”

Vehicle speed control

10 reports
“2018 Kia Forte, purchased certified used June 2022, will randomly go into ECO or Sport mode on startup or while the vehicle is in motion. Vehicle is not equipped with Drive Mode control buttons, indicating that ECO/Sport modes are not supposed to be active feature. While I vaguely remember the mode change occurring during previous two years of my ownership, the first noticeable incident in 2024 was of the vehicle going into ECO mode (green indicator light) happen upon startup the morning of 5/26/24. This was noticeable due to the fact that the ECO mode slow down caused me to nearly be rear-ended by a semi while merging onto the freeway. The vehicle remained stuck in ECO mode for several weeks. On the morning of 6/10/24, while driving, vehicle began to sputter/hesitate and ECO light blinked on/off then switched to Sport (yellow indicator light) mode and vehicle surged forward. Vehicle then switched back to ECO mode and it remained in this mode until the morning of 6/13/24, at which point it went into Sport mode upon startup. It went back into Normal mode (no indicator light) upon startup the evening of 6/13/24. Vehicle was inspective by selling dealership…”

“Engine would run fast and then sound like was going to stop and then it would start shaking and rumbling while driving on highway and in town. Car would stall while at a stop. Gas smells inside the car. Did not feel safe driving. Had the car towed to an independent garage on February 7th and They did an oil change, change 2 Sensors, changed all the spark plugs and changed all 4 Cylinders and on the way home from Starks garage the car was doing the same as before going to the garage with gas smells inside the car, shaking, rumbling and stalling of the engine. And the car wanting to stall while on the highway speed limit of going 60 mph. the next morning My mom and stepdad had the car towed again to another mechanic close to them at Hudson Import Automotive -Napa Auto Care and they emailed a list of problems after inspecting the car. Attaching the list of codes from a diagnostic test from Auto Zone Store # 00791 , and the Estimate for Service from Hudson Import Automotive - Napa Auto Care.

Power train

8 reports1 crash
“While driving the car with the flow of busy traffic, the engine failed and the car stopped. It eventually turn back on (side of the road) but now drives with hesitation, a strange noise, and with the engine light on. This cycle continued until we arrived at the repair shop. And after much research, it seems that this experience is common for other Kia engines. Why was mine not included? Someone could have been badly injured!”
