2020 Kia Sportage engine problems

“"While driving to work and actively attempting to pass another vehicle, the battery light suddenly illuminated out of nowhere. A short time later, while slowing down at a stoplight coming into town, the engine completely stalled out and died in the middle of a busy, active intersection. I lost all acceleration and power steering capabilities, and narrowly avoided an accident while coasting blindly across traffic to safety. The vehicle has had a chronic, active P0420 Catalytic Converter efficiency code caused by a known Kia manufacturing defect of massive, excessive oil consumption (requiring constant oil additions to maintain operation). The excessive oil burning directly fouled the exhaust and caused this sudden, life-threatening engine failure on a public roadway."”

“On Saturday, XXX, while driving on XXX in [XXX], my 2020 Kia Sportage (2,4 L engine, 152,245 miles) suffered a sudden, catastrophic loss of motive power. The vehicle actively entered Limp Home Mode at high speed, dropping velocity rapidly and creating an immediate traffic hazard that my husband and I stranded 6.5 hours away from home. The vehicle was brought back to [XXX] on Sunday XXX, to Stokes Hodges Kia in [XXX], where a diagnostic scan pulled faulted code P0404. No low-oil pressure warning light or dashboard oil alerts were illuminated prior to or during the failure. The engine suffered a sudden internal mechanical failure directly relating to the vehicle's progressive, severe internal oil consumption defect, causing a severe highway safety hazard.”

“My vehicle's check oil light repeatedly lit up on several occassions before my next scheduled maintenance. Contacted my vehicle's manufacturer for assistance and unfortunately got a lukewarm response.”

“My daughter's 2020 Kia Sportage S was purchased September 22, 2025 from a Nissan Dealership with 96,574 miles on it. It dove great. She used it less than 20 miles per day on residential streets to get to and from work and to church on Sunday. It was not used for interstate or freeway driving. By June of 2026, we noticed that it was requiring more oil between oil changes. The oil level was checked at least once every other week to see if more oil needed to be added. We were adding about a quart of oil every two to three weeks although there was no evidence of excess smoke coming from the exhaust. Then on my daughter's way to work on August 13, 2026 she experienced a sudden shaking of the car and the engine light came on. She immediately pulled over and turned off the engine. We were out of town at the time so my son came to see what was wrong with the car. He checked the engine oil first and it was within the right level. The car was limped to the local Kia dealership to trouble shoot it and they said that there was evidence of rod/bearing failure in one cylinder that was causing the shaking. There is no fix for it other than to replace the engine at a dealer…”

“While driving on the expressway posted speed 65 was doing 70, left lane driving, suddenly my check engine light started flashing, my oil light came on and my vehicle started slowing down. Acceleration was not an option, causing hazardous conditions to have to put my hazards on and cross two lanes of heavy traffic. Vehicle went into limp mode. Vehicle was caught up on an oil change, and was regularly checked and filled with oil. Oil seemed to have been burning rapidly or just simply disappearing. The motor blew and i purchased this vehicle less than 6 months ago. I only put 4,000 miles on it. 2020 kia sportage s, dealership was lilliston ford. Took vehicle to kia dealership to get two safety campaigns fixed. They informed me i was only a couple hundred miles over my warranty and my repairs are not covered. I now have an inoperable vehicle that i have payments on, which now needs a new engine. No recalls matching my vin, only my make, model and year. All repairs were denied. Worst vehicle decision ive ever made…”
