2016 KIA SEDONA Complaints

Experienced overheating issues at only 105,000 miles due to leaking cylinder head gasket diagnosed at multiple mechanics, including the local Kia dealership. I was informed that this engine has a common defect where the head gasket bolts strip out of the engine block.

The contact owns a 2016 Kia Sedona. The contact stated that while operating the vehicle, the heater was no longer blowing hot air. Additionally, the engine was overheating. The vehicle was taken to the local mechanic who replaced the thermostat and the water pump, but the failure continued to occur. The vehicle was taken to the local dealer who diagnosed that the rear cylinder head bolts had failed, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 123,000.

There were absolutely no warning lights on my dashboard for the engine, engine oil or anything. I was on a busy 2 lane road with my 7 year old on December 21, 2023 and suddenly the Charging System Warning light and the Immobilizer Indicator came on and the car stopped accelerating. I had to coast off of the road where there was no where to pull over. There are only 61,355 miles on my car and I had just had the safety inspection completed by Kia on September 7, 2023. I had the car towed to the Kia dealership in Leesburg as I always trusted them with servicing my car. They now want me to pay $9,899.72 to replace the long block, starter motor, and intake manifold OR they said they will pay me $500 for my car. The car is in the Kia dealerships lot right now because we would have to tow it somewhere else. The only symptom started 2 days before the incident. When starting the car it made a clicking sound. There were absolutely no other symptoms.

The contact owns a 2016 Kia Sedona. The contact stated that while a State Inspection was being performed on the vehicle, it was discovered that water and condensation were present inside the driver's and passenger’s side rear brake light housing. The contact stated that the vehicle failed the safety inspection due to the failure. The water and condensation were removed from the housing and the light bulbs were replaced but the failure reoccurred during the next rainstorm. The local dealer was notified of the failure, but no assistance was offered. The manufacturer was not contacted. The failure mileage was 97,000.

Coolant all over everything! Mechanics will not touch it. Constantly adding coolant. Can’t drive far. Without overheating. Cracked heater core less then 90,000 miles

Valve cover is cracked, loosing coolant and oil, ruining alternator, smoking, smells like it’s burning. Runs rough, dash lights up. Dies while driving

The contact owns a 2016 Kia Sedona. The contact became aware that the radiator was overheating while driving. There was no warning light illuminated. The contact replaced the thermostat, the radiator cap, and flushed the coolant and radiator system. While driving at an undisclosed speed, the contact noticed that the temperature gauge was indicating that the vehicle had started overheating. Due to the failure, the vehicle was towed to the dealer. Upon inspection of the vehicle, the mechanic discovered that the head bolts on the cylinder heads had been stretched, causing coolant to leak into the engine cylinders. The contact was informed that the engine needed to be replaced. The manufacturer was notified of the failure and informed the contact that there were no recalls on the vehicle. The vehicle was not repaired. The failure mileage was approximately 100,000.

No warning lights ever came on. We took the vehicle to the KIA dealer because the fan stayed on when we shut off the engine and the heat stopped working. The KIA dealer said the vehicle needs a new engine due to head gasket leakage. This vehicle clearly has a major engine defect that could cause the vehicle to breakdown at any time with a failed engine. How does an engine fail without the engine light ever coming on? The vehicle has been properly maintained with timely oil changes and fluid checks.

Engine failed without warning on a trip to urgent care with our daughter. Was running normally, then started losing some acceleration and knocking loudly. Further inspection showed almost no oil in car, with no evidence of a leak. Car is parked in same spot on driveway daily and there isn’t even a drop of leaked oil. Both the loss of power on the freeway and failure with no warning during an emergency left us and others at risk. Our son, a certified mechanic, has confirmed a thrown rod bearing. It failed October 6, Kia can’t even look at it until the 26th. I’m currently incurring the cost of a rental vehicle in addition to the cost of replacing the engine. No warning lights were illuminated before the failure, and none are illuminated after the failure.
