Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
2020 Kia Forte, 2.0L 14F engine, 109,000 miles: On July 3.2026 "check engine" light came on. Drove to local auto parts store to have code downloaded, P0017 cam position sensor. Car was performing fine, except for engine light. Drove car to Kia dealership. While driving, warning light for "front collision system came on and car began performing erratically. Left car at dealership for diagnostics. Yesterday received call from dealer, stating that engine needed total replacement due to "lack of oil". Quoted repair cost estimated at approximately $8,000. Car has been regularly serviced, including oil and filter changes per handbook. I have all records for the services. The were no indications of low oil pressure or engine overheating, no warning lights, all gauge readings displayed normal ranges. This same car had a failed transmission replaced approximately 2 years ago, which was covered by an extended warranty related to a recall. There have been 2 engine failure recalls as a result of 2 class action lawsuits for Kia cars with this same engine failure up through the 2019 model years, providing new engines and/or extended warrantees, however, this does not applicable to 2020 and newer models, even though it's the same exact same engine model with the exact issue causing the failure. Engine failure in traffic condions can obviously lead to immediate safety issues. I currently have a call into the Kia customer service/complaint department, but no resolution offerred to date.
The contact owns a 2020 Kia Forte. The contact stated that while driving at an undisclosed speed, the engine seized. There was no warning light illuminated. The failure had occurred while the contact was driving on a major highway. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that there was no oil in the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that the failure was not covered under an unknown recall. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 103,000.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
The contact leased a 2014 Kia Forte. The contact stated that while driving, the vehicle began to chug. The vehicle was towed to the local dealer, where it was diagnosed as needing a transmission replacement. The vehicle was repaired. The contact eventually purchased the vehicle. After the purchase, the failure recurred. While driving, the vehicle began to chug without warning. The vehicle was taken to the local dealer, where it was diagnosed that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was called, but there was no response. The failure mileage was approximately 200,000.
I am reporting a transmission failure in my 2020 Kia Forte with approximately 54,000 miles. The vehicle experienced a sudden and complete transmission failure on March 19, 2026, on the highway from Cleveland to Cincinnati. after being owned for less than seven months. The vehicle is now at a dealership 2.5 hours away, requiring a full transmission replacement. This appears to be a premature failure and not consistent with normal wear and tear for a vehicle with this mileage. I am aware of a Technical Service Bulletin issued by Kia regarding IVT transmission issues in 2019–2021 Kia Forte models, which may be related to this failure. As well as legal investigations and lawsuits regarding said transmission models. Given the safety implications and potential for loss of power while driving, I am submitting this complaint for review.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.

1st problem, catalytic converter code says it's bad, check engine light on ever since, car is only 4 years old. 2nd problem possible electrical or wiring issue. Had to replace front right headlight(2times), back brake lights both sides, rear top brake light (2 times), daytime running lights both(2 times), currently right light bulb works, but light on says needs replacement. All in total changed 5 to 6 bulbs within 2 weeks of each other, which leads me to believe there is electrical or wire issue? Very frustrated with both issues. Not sure if related but issue just happened, heat blows warm driver side, cold air on passenger side, possible heater core issue. Again car is only 4 years old and should not have this many issues. Please help!
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.

The contact owns a 2020 Kia Forte. The contact stated that while driving 70 MPH on a bend in the highway, a deer jumped over the barrier and landed on the top of the contact's front windshield. The contact stated that she was knocked unconscious due to the impact. The driver’s and passenger’s side air bags did not deploy. The contact was strapped in the driver's seat when she regained consciousness. The contact was unsure whether there was a warning light illuminated. The state police were called to the scene of the accident. Days later, after the accident, the contact went to Urgent Care. However, when the contact explained that she was unconscious, the contact was referred to the hospital. The contact went to the hospital, was informed that there were no bone fractures, and was referred to her personal medical provider. The contact sustained a bruise from the seat belt on her left shoulder; glass shards were embedded in the right forearm. The contact stated that from the impact, the torso slammed into the front windshield. The vehicle was towed to a towing yard, and then the insurance company towed the vehicle to a collision center. The insurance company was pending an investigation. The contact had not released the vehicle. The contact was unaware of all the facts of the accident. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
The lane assist malfunction and periodically jerks. Very unsafe I no longer use this feature . To keep control of the vehicle. I never got it inspected. As the lane assist was in use and it would jerk it would alert me of a lane departure . I mention this to include every known problem I have experienced with the vehicle. The problem That brought me here. Is my engine light came on today. Leading up to this. I have had oil leaks since I've owned the car. Im adding oil in between oil changes due to it being low. In the beginning it was a hint of smell of gas in the oil. I was informed to do more frequent oil changes. Over time the smell of gas grew stronger . No Indication to a problem then. Now the smell of gas is prominent in the oil. When the dip stick is checked its always needing more oil and smells of gas and has blackness like burning in the oil. Now there's a check engine light on. And everything I looked up says to discontinue driving the car. I am having a mechanic look at it with a code reader.
I own a 2020 Kia Forte LXS with approximately 136,000 miles. The check engine light came on with code P0420 (“catalyst system efficiency below threshold”), and an Express Oil Change & Tire Engineers location confirmed the catalytic converter is failing. The back pressure was measured and is within spec but slightly elevated, showing the part is deteriorating. I was also told my O2 sensors are burned due to the failing catalytic converter. This failure affects drivability and safety: the vehicle sometimes struggles on acceleration and hills, and I feel vibrations through the gas pedal. Because I commute 50 miles each way to work on the interstate, sudden loss of power would put me at risk in high-speed traffic. I have learned Kia and Hyundai vehicles from other years/models (including the Forte) have had recalls and extended warranties for premature catalytic converter failure and excessive oil consumption, but Kia has not yet extended coverage to the 2020 Forte. This appears to be the same issue. The vehicle has been inspected by Express Oil Change & Tire Engineers, and the quoted cost for replacement is $3,000–$3,600. This should be investigated for potential recall or warranty extension to include the 2020 model year.

From owner reports, verbatim
Steering wheel is turning completely around and made a noise. I noticed my steering wheel is loose it has been like that for time. But yesterday was the first time it turned completely around were I could not control it.
WHEN BACKING UP THE STEERING, KEY, AND WHEEL ALL LOCK. I WAS BACKING UP SO I WAS ALREADY GOING VERY SLOW. WHEN PRESSING ON THE BRAKE THE CAR SLOWS DOWN BUT STILL MOVES VERY SLOW UNTIL IT CANT MOVE ANYMORE. I TRY TO JIGGLE OUT THE KEY AND PUT THE CAR IN LOCK BUT I JUST JIGGLE EVERYTHING UNTIL SOMETHING UNLOCKS. IT HAS HAPPENED 3 TIMES SINCE I GOT THE CAR IN MARCH 2020.

Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The contact owns a 2020 Kia Forte. The contact stated while driving approximately 30 MPH, the Forward Collision Avoidance camera activated, causing the brakes to stop the vehicle unintendedly. The Forward Collision Avoidance system activated without a vehicle or person nearby. The contact pulled over to the side of the road and waited before restarting the vehicle. The vehicle was started with the check engine warning light illuminated with abnormal gurgling sounds coming from the engine compartment. The vehicle was taken to a certified mechanic who diagnosed that the cam shaft position sensor and the ABS system had failed. The vehicle was not repaired. The dealer was contacted and informed of the failure. The dealer diagnosed the vehicle with engine failure. The Forward Collision Avoidance camera failure was not diagnosed or replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 103,069.
MY 18 YEAR OLD DAUGHTER WAS THE DRIVER. THE CAR WAS PARKED ON A RESIDENTIAL STREET, FACING THE DIRECTION SHE WANTED TO GO. THE STREET WENT DOWNHILL IN FRONT OF HER. SHE STARTED THE CAR. WHEN SHE BEGAN TO DRIVE, THE STEERING FELT VERY STIFF, SHE COULD BARELY STEER. SHE STARTED DRIVING ANYWAY. THEN THE BRAKES DID NOT WORK. IN FACT, SHE SAID THAT PRESSING THE BRAKE SEEMED TO MAKE THE CAR GO FASTER (OR THIS COULD HAVE JUST BEEN THE EFFECT OF THE HILL). SO SHE ACCELERATED DOWN A SUBSTANTIAL HILL WITH NO BRAKING POWER. AT THE BOTTOM OF THE STREET (APPROX. 1/4 MILE) IS A T-INTERSECTION. SHE CROSSED THE STREET, THE CAR WENT UP ONTO THE CURB OPPOSITE, PROCEEDED THROUGH SOME BUSHES, KNOCKED DOWN A FENCE AS IT WENT BETWEEN A TREE AND A BRICK WALL, RAN INTO A BIRD BATH, AND THEN CAME TO A STOP IN SOMEONE'S YARD. FORTUNATELY THE CAR STOPPED BEFORE IT GOT TO THE HOUSE ITSELF. DAMAGE INCLUDED: BOTH BUMPERS, BOTH DRIVER-SIDE TIRES/WHEELS/HUBCAPS, AND EXTENSIVE DAMAGE UNDERNEATH INCLUDING TRANSMISSION.DRIVER AND PASSENGER WERE (AMAZINGLY) NOT INJURED.

From owner reports, verbatim
While I am driving it is hard shifting and idling high, sometimes it doesn't want to pick up speed when starting from a stop. The wheels locked up going down a off ramp. There are no warning lights or anything on the dash. I will have it checked Monday but this started out of the blue. I have had regular maintenance on the vehicle and have all my receipts for proof. This is a serious issue especially with the wheels not functioning right and speed control is fluctuating.

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
The latch for the drivers seatbelt is no longer functioning properly, dealer stated that the hook that holds the buckle in was worn down. Car has 50k miles and is slightly over 5 years old, seems unreasonable that a seatbelt latch would fail that early. In the past, when inserting the buckle into the latch it would not properly latch and immediately fall out, and then once latched again it stayed. Recently it came unbuckled during a drive which caused concern to bring to dealer for inspection. Seatbelt latch issue was missed in PA state safety inspection a few weeks prior to the diagnosis of broken hook in latch.

Tires & wheels
Reports naming tires, wheels, hubs, or the tire-pressure monitoring system.
From owner reports, verbatim
Two sets of Kumho Solus TA 31's (195/65 R15 91T) experienced rapid tread wear issues. The problem and safety issue has been confirmed by Fred Beans Kia of Mechanicsburg, PA, but with hassles to do so. I believe this matter actually effects consumers nationwide, which leads to additional high replacement costs as a result of product quality. Consumers are effected by not just the manufacturer, but by those who knowingly sell & promote the products, such as dealerships like Fred Beans, while aware of the defects or who should know about the defects yet fail to take adequate measures to properly rectify the situation or warn consumers. Kumho Tire has been involved in many lawsuits, primarily related to tire defects which caused serious injuries & multi-million jury award and even trademark infringement where tires are allegedly being falsely marketed & sold as new. I believe Kumho is engaging in breach of warranty where the product they sell fails to meet promised quality or performance standards, while engaging in false advertising that misleads the consumer. They engage in lies in their marketing. In addition, there is negligence with Kumho where the manufacturer fails to exercise reasonable care during production. In addition, there is strict liability where the manufacturer should be held accountable for producing an inherently dangerous product. This has also been outlined in lawsuits & ongoing legal challenges faced by Kumho Tire over product quality. Dealership service managers even deny there is a problem, claim it's normal, and say they can't do anything, unless pressed or are caught in a lie. It appears dealerships, sellers of tires & Kumho are all involved in a scheme that creates additional high costs for consumers to properly resolve the problems. Especially since it's a hassle for people to file complaints or time consuming & monetarily challenging for most to fight the battle with dealerships like Fred Beans, or tire manufacturers, like Kumho.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
