FUEL/PROPULSION SYSTEM, ENGINE, LANE DEPARTURE: ASSIST
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.

FUEL/PROPULSION SYSTEM, ENGINE
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.

Kia is lying to a judge in Lancaster county PA and federal court by stating I did not opt out of class action when they know I opted out end of 2023. Kia also knows these cars are still being stolen and have taken no action to prevent thefts or damage to vehicles. The "upgrade" does not work. My car sustained 7000.00 of damage in May 2025 and had the "upgrade" installed. On the same night, the same people stole multiple other kias and caused severe damage to numerous other vehicles within a 20 mile radius. My report was made to pa state police. The only reason why they didnt actually steal my car was because on same night they tried to also steal my neighbors sorrento at same time. When they attacked her car, her alarm went off and the group fled in 2 sedan type vehicles. Kia has done absolutely nothing to prevent thefts or damage to these vehicles and now have lied to judges in my case. They are trying to force me back into the class action as they dont want to pay me for damages they caused and the class action settlement is a joke. That is why I opted out almost 2 years ago now. Kia are liars.

POWER TRAIN
We were driving on vacation in the Nevada desert on a Sunday when the RPMs began to bounce between 2,000 and 4,000 RPMs causing the carto jerk back and forth when we were going up hill. This continued until it got to the point where the engine was going 8,000 RPMs but we were not moving forward. It felt like when driving a stick shift and you are out of gear. We pulled off and were towed to St. George, UT. The tow truck said it was the transmission and that we should go to a Kia dealer because it would be covered by warranty. No warning lights came on. Our mileage was 70,000 miles. The dealer said they could not find anything wrong and suggested it was bad gas. After paying $150 we were sent on our way back home through the mountains. We got about 20 minutes on the road when the car starting doing the same thing again as we went up hill. We immediately turned around and made it to the dealer in St. George. They checked the car again and found the transmission fluid was black instead of red. They eventually got approval from Kia for a new transmission. It ended up taking 5 days to finally get our car working. while the transmission installation was covered, we ended having to pay $2,000 in out of pocket expenses. Kia claims to have a Trip Interruption Policy to cover expenses when they have a failure covered by warranty when you are on vacation. At best, it only covers $100 per day for a maximum of 3 days ($300). But you have to have pre-approval before they will even pay that little amount. We made a mistake buying a Kia but it is one we will never make again. It was interesting to see how many similar transmission incidents with the 2020 Forte have happened when they hit 70,000 miles.

The multimedia screen is delaminating. The screen ends not working making all functions in it inaccesible. Dealer only provides solution if the vehicle has less than 3 years or 36000 miles. The manufacturer only claims to its warranty terms. The screen starts delamination and evolves day by day.

SEAT BELTS
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.

ENGINE
My vehicle lost 3 quarts of oil between oil changes somehow. The engine is bad now and has to be replaced. Never did a check engine light or oil pressure light come on to alert me that my car was burning oil somehow and the oil was low. At the oil change a few weeks ago the techs underneath my car called out that everything was normal under the car. No leaks, no oil spots anywhere. My safety was put at risk because I drive a very busy highway to work every day. If I had been in heavy traffic at the time of engine failure I could have gotten into a wreck or caused a wreck. If a check engine light or low oil pressure light had come on, this whole situation could have been completely prevented. The issue has been confirmed by the dealership on 5/7/25.

POWER TRAIN
Transmission from the original factory failed on it. I was driving when the engine check engine light came on and my car started ringing at me to get it serviced. I got the transmission replaced and not even 2 days later a brand new transmission failed yet again. This time the transmission (new) was revving up and down while driving at a consistent speed for a few minutes. Then my car started slipping gears when I tried to accelerate. The check engine light then came on again after my car started slipping gears stating to get it serviced. It is currently having its THIRD transmission put in.

My vehicle has 74,000 miles on it. While driving on the highway at 70 mph, the RPMs began fluctuating erratically, jumping from 2,000 to 3,000 and then from 2,000 to 5,000 before the car completely slipped into neutral. I was stranded in the middle of nowhere. Took it to the dealership and since it's out of warranty they quoted me 3500 American dollars to replace the transmission. Don't buy a Kia.

ELECTRICAL SYSTEM, POWER TRAIN
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!

The contact owns a 2020 Kia Forte. The contact stated while driving approximately 55 MPH, the check engine warning light, and a message that Kia had been alerted of a failure was displayed on the instrument panel. The contact stated that the vehicle lost motive power and stalled. The contact was able to start the vehicle and drove back to the residence. The contact stated that while attempting to restart the vehicle, the vehicle was making an abnormal knocking sound before stalling. The contact called an independent mechanic who diagnosed the vehicle on site and determined that the intake and exhaust cam shaft position sensors had failed and that metal shavings were found obstructing the cam shaft sensors. Additionally, the vehicle was very low on engine oil. The vehicle had received an oil change approximately 3-months prior to the failure. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 80,000.
