general problems of the 2020 Kia Motor Forte

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.

I leased car 2020 illinois. No problems. I had car transported to in 2022 to los angeles, and after a few months, the car would check engine light all lights I believe, and car suddenly stops and dies out at each stop light. This happened 3 times and frightened me. It happened every couple months and the repair people never put notes on the repair invoice!! about exactly why I was bringing car in for repair, even if nothing on computer showed up, almost like the defect was bypassing (tricking computer) inspection. Have to restart and it would lost all power seconds later and on rainy days, passenger floor soaked. Nothing on repair places nor dealership would show any problem to fix?? however, when brought back to illinois, no problem with car, so far since January. So car did not like California or their emission gasoline no good. Plus even in heavy snow and rain last 3-months in illinois, passenger carpet never got wet.

When fueling after pump auto shut off gas will spill out, causing a gass spill. Dealership has stated there is no fix. Rear driver side window will not lower with switch. Dealership is well aware but states there are no fixes. Also coolant light came on over the dash and the coolant was low with less than 9k miles. Car is less than 1 year old and has less than 10k miles.
