2020 Kia Forte Engine Problems

Your car has an oil leak that's causing the oil level to drop between oil changes, and you've noticed a strong gasoline smell in the oil along with dark discoloration, which suggests fuel is mixing into your engine oil. Your lane departure warning system also jerks the vehicle unpredictably, which you find unsafe. Your check engine light recently came on, and these issues together indicate a potentially serious engine problem that needs immediate professional diagnosis with a diagnostic scanner.

Your 2020 Kia Forte lost 3 quarts of oil between scheduled oil changes without any warning lights illuminating, and the engine has failed completely and requires replacement. No check engine light or oil pressure warning appeared to alert you to the problem, and a recent inspection found no visible leaks or oil spots underneath the vehicle. The dealership confirmed this issue on 5/7/25, and the lack of warning could have put you at serious risk if engine failure had occurred during heavy highway traffic.

Your check engine light is on due to a failing catalytic converter, which has been confirmed by a mechanic. You're experiencing reduced acceleration power on hills and vibrations through the gas pedal, which could be unsafe during highway driving. The catalytic converter and oxygen sensors will need to be replaced, likely costing $3,000–$3,600.

Your check engine light came on and your engine is burning oil. A mechanic says the engine needs to be rebuilt. Since your car is financed through Kia, you may want to contact them to see if this repair is covered under your warranty or financing agreement.
