2015 Kia Sedona Powertrain & Transmission Problems

My Husband was driving my van with me and my 2 children inside the vehicle and the vehicle lost all power and stalled in the middle of the road and would not restart there was no warning light no noise from the motor or anything. The problem has been confirmed by a independent garage and a Kia dealer this happened on 12/20/25

The contact owns a 2015 Kia Sedona. The contact stated that while driving at an undisclosed speed, he heard a loud pop and the tachometer redlined, after which the vehicle inadvertently lost motive power. The contact was able to coast to the shoulder of the roadway, where he observed that the engine block had separated from the engine with oil covering the entire engine compartment. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure, but since the failure had not caused a fire or an injury, no assistance was provided. The failure mileage was 112,000.

OUR 2015 KIA SECOND MINIVAN OVERHEATED REPEATEDLY IN 2020 FOR UNKNOWN REASONS RESULTING IN A TOTAL ENGINE FAILURE AND COMPLETE LOSS OF VALUE. AFTER LEAVING A HIGHWAY, THE MINIVAN OVERHEATED, RESULTING IN A BLINKING ENGINE LIGHT. IT WAS QUICKLY PARKED AND LATER DRIVEN TO A MECHANIC, WHO COULD NOT REPLICATE THE PROBLEM. AFTER A PERIOD OF OPERATION AT NORMAL TEMPERATURES, IT BEGAN TO MISFIRE. NO WARNING LIGHTS APPEARED PRIOR TO OR DURING THESE MISFIRES. NONETHELESS, WE HAD THE STARTER COILS REPLACED BASED ON A REPAIR CODE. AFTER ANOTHER PERIOD OF NORMAL OPERATION, IT AGAIN BEGAN TO MISFIRE AND OVERHEATED WITHOUT TRIGGERING ANY WARNING LIGHTS. WE DROVE IT IMMEDIATELY TO OUR MECHANIC, WHO DETERMINED THAT THE HEAD GASKET WAS BLOWN. A KIA DEALER TO WHICH WE TOWED THE CAR CONFIRMED THIS ASSESSMENT AND REPORTED IT NEEDED A $6K NEW ENGINE THAT WOULD COST $3K TO INSTALL. (NEITHER WE NOR OUR INDEPENDENT MECHANIC COULD LOCATE A USED ENGINE FOR LESS THAN $4K.) IN ITS CURRENT STATE, THE DEALER ESTIMATES THAT THE 5 YEAR OLD MINIVAN'S TRADE-IN VALUE IS $500. KIA REGIONAL IS UNABLE TO CONFIRM THAT A REPLACEMENT ENGINE IS AVAILABLE AND THEIR REPRESENTATIVE REPORTED THAT IT IS REMANUFACTURING THESE ENGINES AND MAY NEED TO WAIT FOR PARTS TO BE CREATED AND SHIPPED FROM SOUTH KOREA. THE 2015 SEDONA ENGINE IS OF THE SAME TYPE (KIA LAMBDA II 3.3L V6 GASOLINE DIRECT INJECTION) INCLUDED IN VEHICLES THAT WERE THE SUBJECT OF THE RECENT ENGINE FIRE LAWSUIT (ANDREA SMOLEK V. HYUNDAI MOTORS AMERICA AND KIA MOTORS AMERICA). HOWEVER, THE SEDONA WAS NOT INCLUDED IN THE SETTLEMENT OF THAT CASE OR THE RELATED RECALL.

THE ENGINE STOPPED AFTER DRIVING THROUGH A SMALL BUMP AT THE PARK LOT (LOW SPEED), ACCOMPANIED BY STEERING WHEEL LOCKING BY ITSELF. TRIED TO RESTART THE CAR AND IT DIDN'T WORK. JUMP START WAS ALSO UNSUCCESSFUL. THE CAR WAS TOWED TO THE NEARBY DEALERSHIP. AFTER DAYS OF WAITING, I WAS TOLD PROBLEM CAN NOT BE DIAGNOSED BUT THEY OFFER TO REPLACE THE COMPUTER. NOW I AM WAITING FOR THEIR NEW RESULT.
