“On August 22nd, I was driving from the grocery story to my house (5 miles away) when the transmission started failing only going on 2nd gear and the check engine light came on, when I got home, I called my mechanic and he connected his code reader to my card and the error code is P090B$07E9 Clutch "B" actuator control circuit performance error, he told me that Kia motors had an open recall for the clutch actuator, I called the Kia dealer to make an appointment for August 26th I told them the issue with my car and they told me they will check that error, it took two weeks for them to return my car and they told me that they replaced only the fuse for the Recall SC275 / NHTSA 23V534000 and they told me that I needed a new transmission and the price to replace it was $6,000.00 plus tax, I told them that the issue it was because the clutch actuator, they said no, so I took my car home, and took it for a second opinion with an independent service center, after the inspection they told me that the transmission failed and it was stuck on the 2nd gear and it was better to replace the transmission, I went back to the Kia dealer ship and demand a formal diagnostic report…”
“A major drivetrain service and repair was completed by an authorized manufacturer dealership. After picking up the vehicle, an unusual front-end/steering noise was immediately reported to the staff. Over just 390 miles of driving, the symptom worsened. A subsequent formal inspection by a separate, independent authorized service center confirmed the root cause of the safety failure: the primary axle nut had been left completely unstaked during the initial drivetrain assembly, rendering the vehicle entirely unsafe to operate. The vehicle was grounded to prevent an accident. Because the mandatory safety protocol of staking the axle nut was omitted, the critical fastening hardware was allowed to back off under normal driving conditions. This component failure directly compromised the structural integrity of the front drivetrain, steering knuckle, and wheel hub assembly. Had the vehicle continued to be driven, the omission presented an imminent risk of complete mechanical separation, which could cause a wheel assembly to detach or lock up while in motion at high speeds, putting the safety of the occupants and other motorists at extreme risk. The vehicle remains…”
“The contact owns a 2019 Kia Niro. The contact stated while driving at an undisclosed speed, the vehicle jerked. The check engine warning light and the hybrid battery warning light were illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the clutch actuator was leaking, and the dual clutch and slave cylinder needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure but denied assistance in covering the cost of the repair. The contact stated that the engine and dual clutch were replaced two years ago. The contact related the failure to NHTSA Campaign Number: 23V534000 (POWER TRAIN); however, the VIN was not included. The failure mileage was approximately 100,000.”

The contact stated that while operating the vehicle, the message "Pull Over and Shut off Engine" was displayed and a burning odor was coming from the engine compartment. After restarting the vehicle, the failure was self-corrected. The vehicle was taken to the local dealer who determined that fluid had leaked into the clutch actuator and the clutch actuator needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the VIN was previously inspected as part of the NHTSA Campaign Number: 23V534000 (POWER TRAIN). The contact stated that the vehicle experienced the failure listed in the recall. The failure mileage was 35,000.”
“The contact owns 2019 Kia Niro. The contact stated that on several occasions when the vehicle was started, the check engine warning intermittently illuminated. The contact stated that while driving and accelerating, the vehicle lost motive power momentarily. The vehicle was taken to an independent mechanic and DTC: P074A, P1921, P074A/73, and P1921-77 were retrieved. The vehicle was taken to a dealer where it a diagnosed and determined that the transmission gear actuator needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 75,000.”
“2019 Kia Niro DCT engaged REVERSE during manual 1→2 upshift attempt in Sport Mode, causing violent reversal. Resets with ignition cycle. Smell of burnt clutch present. Happend at 41,000mi, then 73,000mi then again today at 154,584. Believe it may be a faulty range selector, corrupted tcu logic, or both. **Canadian Recall R238 (May 2022)** for DCT clutch actuators”
