I am reporting a transmission failure in my 2020 Kia Forte with approximately 54,000 miles. The vehicle experienced a sudden and complete transmission failure on March 19, 2026, on the highway from Cleveland to Cincinnati. after being owned for less than seven months. The vehicle is now at a dealership 2.5 hours away, requiring a full transmission replacement. This appears to be a premature failure and not consistent with normal wear and tear for a vehicle with this mileage. I am aware of a Technical Service Bulletin issued by Kia regarding IVT transmission issues in 2019–2021 Kia Forte models, which may be related to this failure. As well as legal investigations and lawsuits regarding said transmission models. Given the safety implications and potential for loss of power while driving, I am submitting this complaint for review.

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.

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.

Check engine light came on, got a code of P0867-Trans Fluid Pressure reading. May need a transmission fluid pressure sensor replacement, or to replace the transmission control module. Lastly, it could be a leak.
