2018 Kia Niro

The vehicle just shut down as I exited. The power and gas pressure decreased. Pulled over to see if my hybrid battery was defective or drained. It wasn’t. A notification popped up and said “Hybrid Control System or Low Voltage DC/DC Converter, Contact dealer for service. Finally got it towed to Kia of Valencia the next day and they said it was “Hydraulic Clutch Actuator” and they want charge me $2200 to fix it. But looking up the part, it says there’s a recall for that exact problem.

The contact owns a 2018 Kia Niro. The contact stated while driving at an undisclosed speed, the engine revved up. The contact stated that the accelerator pedal was depressed; however, the vehicle was slow to respond. Eventually, the vehicle shifted into gear and started to move. The contact stated that the check HEV and turn off engine error messages were displayed. The vehicle was taken to the local dealer, where it was diagnosed that a faulty engine clutch activator needed to be replaced. The mechanic informed the contact that the vehicle was not covered under a recall. The vehicle was not repaired. The contact stated that the failure was related to NHTSA Campaign Number: 23V534000 (Power Train). The manufacturer was not contacted. The failure mileage was approximately 120,000.

The car can slow down suddenly in the middle of traffic even if I accelerate. The engine has a problem according to the mechanics who was trying to fix my car twice without succes. The car does not hold coolant liquid for more than 15 minutes. It looks like the coolant is staying somewhere in the engine. It overheats too. Yes the car is available for inspection upon request. It's a high risk because the car can suddenly slow down in the middle of traffic or when leaving a light turned green. And the last time I drove it there a weird smell. Yes, an independant service center located at College Park Maryland informed me about the issue. The vheicle or compenent has not been inspected yet by the manufacturer, police, insurance representative or others. When the car starts slowing down in the middle of traffic, I feel a kind of vibration first on the gas peddale and comes up the engine light. This happened last month

I WAS DRIVING ON THE FREEWAY. AFTER SLOWED DOWN AND STOPPED COMPLETELY, SUDDENLY IT LOSE POWER TO RUN. TRYING TO STEP DEEPER THE GAS PEDAL, BUT NO REACTION AT ALL. AFTER TURN OFF AND TURN ON ENGINE FEW TIMES, IT CAN RUN AGAIN, BUT THIS TIME, THE REAL PROBLEM OCCUR. THE ENGINE SOUNDS SO LOUD..IT'S HYBRID CAR SUPPOSED TO SO QUIET (THAT'S WHAT SOUNDS USUALLY). LATER ON, I FOUND OUT HOW TO STILL CAN DROVE IT, BUT WITH HIGH RISK SUDDENLY LOSE POWER ON THE STREET. LATER FOUND OUT, WHEN THE CAR IN MOTION, THE HYBRID SYSTEM DIDN'T WORKED COMPLETELY, AND THE TRANSMISSION SOUND VERY ROUGH. EVERY TIME WHEN COME TO BRAKE OR WANT TO SLOW DOWN, CAN FEELS OBVIOUSLY AND HEARD THE TRANSMISSION IS VERY ROUGH MAKING CLUTCH LOUD SOUNDS. THE CRUISE CONTROL SYSTEM ALSO TOTALLY NOT FUNCTION. WHEN IN STATIONARY, VERY FIRST WHEN STARTED THE ENGINE, MADE LOUD SOUNDS ON THE ENGINE, AND CAN'T REVERSED OR MOVE FORWARD, JUST STAYED IN PLACE. THE DASHBOARD DISPLAY "CHECK HYBRID SYSTEM". AND ON THE MIDDLE SCREEN DISPLAYING, "LOW VOLTAGE DC / DC CONVERTER".
