2018 Kia Niro Phev Recalls & Complaints

Incident: February 25, 2026 · Filed: June 1, 2026

Year/Make/Model: 2018 Kia Niro Hybrid Mileage at time of incident: approximately 69,000 Component: Hybrid Propulsion System / Powertrain My 2018 Kia Niro Hybrid has experienced five recurring "Hybrid System Failure — Turn Off Engine" errors occurring without warning while the vehicle was being operated. Each occurrence rendered the gas engine ineffective in moving the vehicle, creating an immediate safety hazard. The driver was forced to quickly navigate to safety each time. The vehicle has been brought to the dealership four times for this issue — February 25, May 4, May 15, and May 30, 2025. On May 30 the dealer performed a repair they stated would resolve the problem. The vehicle was returned the same day. On May 31, one day later, the error occurred again. The defect remains unresolved after four service visits. Out-of-pocket towing and rental car costs have been incurred each time. I believe this defect is related to the hydraulic clutch actuator issue covered under Kia recall SC276 and the active class action lawsuit (FeganScott v. Kia/Hyundai). The recall repair has not resolved the problem.

I received KIA letter about the recall SC276 for HCA issue around 1/15/24. I brought my 2018 Kia Niro PHEV to Kia Dealer in San Jose. They inspected and concluded that the vehicle is safe with the recall SC276. However, they did not replace the fuse as stated in Kia's recall instructions. Ten days later, I was on the road, slowing down at the intersection and the car suddenly lost power, the Dashboard show the message for 'EV System failed'. My battery was fully charged at work, which is 2 miles away. My gas tank was full and I couldn't start my car again. Lucky enough, I was 1/4 mile away entering a Freeway. I couldn't imagine what would happen if I was on Freeway. Police stopped by, put road warning while I scrambled to get a tow truck. An hour later, they was able to move my car off the road. The first Kia Dealer is 3 miles away. They, however, refused to service my car because the other Dealer in San Jose already checked my car for recall before. I had to tow my car 36 miles to San Jose Kia Dealer. I asked them to check again if it was the issue with the recall. Kia Dealer diagnosed and concluded that the 'Relay Assembly Power' unit, Fuse-High Voltage failed for whatever reason. I asked for picture of the damage part and haven't received them. The Dealer said they still have system message which Kia's Engineers haven't figured out why. I am on the 3rd week without a car. I don't have a car to go to work and pick up my kids. I am renting a car at $300/week for my family and work tasks.

I was driving myself and two passengers on a highway at night in the rain. I was using the adaptive cruise control and was maintaining speed when i went through a puddle and I think the car hydroplaned a little. A warning sign flashed up on the dash that said something towards "deactivating cruise control" - i am not sure of the exact warning. I've had a warning similar, im not sure if its the exact same, when the adaptive cruise control turns off in traffic and it slows down and turns itself off. But when it turned off this time after the puddle I tried to take control of the car and the gas pedal was completely unresponsive. Pedal to the metal, nothing. I was, thankfully, the only car in sight, so i was able to change lanes and check my brakes, which worked, and coasted/braked my way off the shoulder. I turned the car off and then back on and the car and pedal responded normally.

In July 2023, Kia identified a defect that can increase the risk of an engine compartment fire while driving; namely that the printed circuit board in the hydraulic clutch actuator may become contaminated with fluid and lead to an electrical short circuit. To date, there is still no remedy available. I am filing this complaint for your assistance in ensuring the company provides a remedy within a reasonable time.

2018 KIA NIRO PLUG-IN HYBRID, 16,235MI. VEHICLE HAS BEEN IN 5 TIMES IN LAST SEVERAL MONTHS FOR A TOTAL OF OVER 30 DAYS IN SHOP. TRANSMISSION WILL DO A VERY HARD DOWNSHIFT INTERMITTENTLY WHEN STOPPING. MAKES VEHICLE DIP HARD..NOTICEABLE ON DASH CAM VIDEO. ON HARDER ACCELERATION, POWER TRAIN HAS TROUBLE DECIDING WHAT TO DO AND OFTEN THERE IS A NOTICEABLE DELAY IN ACCELERATION. FEELS SORT OF LIKE IT IS SLIPPING, BUT IS A DELAY IN POWERING THE ELECTRIC MOTOR FULLY AND STARTING THE GAS MOTOR.THIS HAS CAUSED A COUPLE CLOSE CALLS WHEN PULLING INTO TRAFFIC EXPECTING THE CAR TO REACT APPROPRIATELY. SOME ONLINE RESEARCH SHOWS THIS IS NOT AN UNCOMMON OCCURRENCE. DEALER HAS REPLACED A HYDRAULIC ACTUATOR, BLED SYSTEM AND REPROGRAMMED PCM. THIS FIXED A SQUEAK NOISE IN POWER TRAIN BUT NOT THE HARSH/ERRATIC OPERATIONS. AS FOR THE BRAKES, RECENTLY, DEPRESSING THE BRAKE WITH MORE THAN LIGHT PRESSURE CAUSES A RUBBERY GROAN SOUND FROM UNDER DRIVER'S DASH. THIS HAPPENS MORE WHEN THE CAR IS COLD OR SITTING FOR SOME TIME, LESS AFTER IT HAS WARMED UP. DURING THESE EPISODES, THE BRAKE PEDAL TAKE MORE EFFORT TO PUSH AND BRAKE ENGAGEMENT IS DELAYED. THE NOISE WILL HAPPEN WHEN YOU STEP ON THE BRAKE TO START CAR OR WHEN DRIVING. DEALER HAS BEEN DISMISSIVE ABOUT THE ISSUES. WE WERE TOLD WE WOULD GET A 'FLIGHT RECORDER' TO HELP THEM DOCUMENT THE TRANSMISSION ISSUES AND RECORD VEHICLE DATA FROM THE COMPUTERS. TODAY WE WERE TOLD WE WILL NOT BE GETTING IT AND TO COME PICK UP THE CAR. KIA CORPORATE IN IRVINE, CA HAS BEEN NOTIFIED AND A CASE HAS BEEN OPENED. WE ARE WAITING ON A RESPONSE NOW.
