2020 Kia Optima power train problems

“While driving to work, my 2020 Kia Optima suddenly lost engine power and went into limp mode in the middle of the highway, leaving me stranded and creating a severe safety hazard in traffic. The check engine light immediately started flashing and displaying diagnostic code P1326 which indicates an abnormal engine and/or a catastrophic rod bearing failure. This problem has been confirmed by the Kia dealership along with a 3rd party auto repair shop. However, Kia is refusing to cover the inspection, diagnostic, or any repairs due to the vehicle not having any open recalls, having more than 100k miles and the model of my vehicle despite this being a well known and documented manufacturing defect issue to these engines. The vehicle is currently available for inspection.”

“While driving, my 2020 Kia Optima suddenly lost engine power and went into limp mode on the road, leaving me stranded and creating a severe safety hazard in traffic. The vehicle threw diagnostic trouble code P1326, which indicates a catastrophic rod bearing failure. The problem has been confirmed by a Kia dealership scanner. However, both the dealership and Kia America are refusing to cover the inspection and repair under their safety campaigns or goodwill due to the vehicle having 180,000 miles, despite this being a well-documented manufacturing defect inherent to these engines. Prior to the failure, the check engine light started flashing. The vehicle is currently available for inspection.”

“Engine replacement needed at 99,782 miles. P1326 code continuously popping up. Also has excessive oil consumption and electrical problems concerning the forward collision system. Kia refuses to replace engine although the P1326 code is covered by lifetime warranty. The cause of the incident was defect in engine resulting in a recall of all 2011-2019 models. The 2020 Kia optima LX contains a 2.4L GDI engine which has identical problems relating to previous lawsuits.”

“Car is consuming oil every three weeks. Engine is going to burn if it does not stop. It’s not in a class action but probably should be. It’s been 4 months and over 1,000 spent.”

“I purchased in July 2020, from sept 2020 I've had it at the dealership with shuddering, stalling and loss of acceleration. I originally thought fuel pump or transmission but kia said no. then in 2022 I received a letter from kia corporate stating low pressure fuel pump failure. so i called the dealership and told them the letter states everything I had been in to see them about numerous times. made an appointment they said they found an error but had no fix. I complained heavily due to the fact I sat there for 4 hours, and they knew they had no fix as of yet. It was too dangerous like this. so the Manager said he'd just replace it with a whole new fuel pump but it could also fail. I sent the car in for 4 days just to find out they did not replace it. they only changed the fuel filter. stating kia wont let them put in a new pump due to their system not showing any other issue. The problem persisted and multiple visits to kia to no avail. Then on top of that my air bag light came on Jan 4, 2024. They said it was my responsibility it's not covered 1138.67 it would cost me. Then in Feb kia corporate sent me a letter about airbags. I did not go back because the…”

“I have kept up on regular oil changes and maintenance on my Kia which I bought new 5 years ago. My issues started when my car's orange check engine light came on, I experienced loss of power such as difficulty accelerating even at low speeds, especially up hill. As soon as I was able I checked my oil which and there was nothing on the dipstick. I put in 3 quarts of oil. I brought it into my usual dealership for service and let them know about the oil issue and issues with power when driving. They failed to address the root cause of the issue, they performed an oil change, engine light turned off, and they started an oil consumption test. But when I drove off the lot the issue with the power continued, and the check engine light came on again. I took my Kia to another dealership to address the car's power issue and the first oil consumption test was not completed because it was unsafe to drive. When I brought my car in, the check engine light was not on, even though there were significant power issues. The dealership was able to confirm my concern, including loss of power and evidence of oil overconsumption. They replaced my turbocharger under warranty. I then…”
