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.
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.
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.
Transmission was having issues, car would not accelerate properly. Engine light came on and vehicle was towed to the original dealership for inspection where they confirmed transmission had gone out and it did get replaced. Vehicle was driving strange for about 3-4 days before engine light came on (12/30/2023).

MAKE: 2020 KIA FORTE MODEL: FORTE ODOMETER: approximately 88,000 miles VIN: [XXX] [XXX] On [XXX], while driving my Kia towards my home driveway, I noticed that the car's speed was fluctuating unpredictably. Despite having my foot slightly on the brake and off the gas pedal, the vehicle continued to accelerate and decelerate as I made the turn into my residence. The Forte exhibited irregular and sluggish shifting, displaying a reluctance to engage or maintain gears, as well as experiencing missed or delayed gear changes. Additionally, it demonstrated unpredictable trembling and stalling occurrences multiple times while being driven in the driveway. The check engine light turned on. I promptly deactivated the engine and abstained from operating the vehicle. Afterwards, I had the vehicle undergo a scan, during which the check engine light turned on, indicating the presence of the code P0730. Without delay, I scheduled an appointment for service and maintenance at the Kia Bulldog dealership located in Athens, Georgia. Following a consultation with the service department, I scheduled a diagnostic assessment and test drive for the vehicle. On [XXX]. The mechanic at Bulldog Kia conducted a thorough examination of the vehicle and diagnosed it after performing a test drive. Additionally, he confirmed that he observed the same driving condition that I had previously described to him. It was associated with the transmission which related to the sc. However, when he scanned the vehicle for any code, the code reading was not accessible. I have photographic evidence of the exact state of distress and audio recordings of the car's engine accelerating as I approach the residence. I consulted a nearby mechanic with extensive expertise, who thoroughly examined and scanned the vehicle. The mechanic determined that the problem may be related to the transmission bearing, which corresponds to the diagnostic code P0730.

On highway at 65mph engine began revving, accelerating higher on its own then speed would drop down 10-15 mph, erratic tachometer going up to max 6 at 65 mph, slipping gears and took total control of speed and then dropped down to 10mph at 6 tachometer and then wouldn’t go past 5 mph. No warning lights, no check engine.
My expectant granddaughter was driving the vehicle on a trip. The transmission started intermittently slipping en route. She stopped and when she returned to the vehicle she discovered it would no longer go forward or backwards. It is still under warranty. The vehicle is still in Colorado. This happened Sept 4, 2021. It is now 10/13. I have contacted Kia multiple times speaking with different people. I escalated the call and was told someone named Melissa was my escalations person. I have never spoken to her. I have requested a buy back of the vehicle due to possibility of reoccurrence. My granddaughter was stranded for a week. The car is at a dealership, Ft Collins Kia. We have had to pay for hotel, car rental, and a flight out of pocket. I requested reimbursement. They have not responded. I filled out the information for the buy back, but I do not have all of the paperwork. It is in the car in Colorado. We live in South Texas. No way to get access to it. This is wrong on so many levels. We are at a loss as to what to do. If the transmission had quit while she was moving the results could have been disasterous. Kia says the part is sitting on a dock somewhere waiting to be picked up. Is there an expected timeline? We had to replace the vehicle due to the cost of car rentals.
