Van was well cared for. Engine failure occurred while on interstate, causing immediate high-pitched squealing. Problem with 2015 models seems to be known to Kia, and they told us we'd have to replace the engine entirely. No warnings, messages, or symptoms prior to or following failure. Still turns on but afraid to hurt engine further while driving with the terrible noise. We are crushed that such a good vehicle, having been well taken care of and serviced, should have such a distinct, unavoidable, and irreversible loss. Grateful that we were able to pull over, despite the numerous cars surrounding us, and to be safely towed. Won't trust Kia the same way in the future.

The car has 107,000 miles, and one day while driving, the coolant temperature suddenly spiked. I scheduled an appointment at Kia service (Glassman Kia Michigan), and the available appointment was in four weeks. The local mechanic checked the water pump and, after removing it, determined it was good, but he installed an aftermarket gasket because that's the only one available in local stores. At Kia, they replaced the pump with a new one, but the overheating problem persisted. After the car spent five weeks at the service center, they determined it was the head gasket. They offered me an engine replacement (costing $10,000). They never contacted Kia headquarters about a warranty replacement. Engines in 2015-16 Kia Sedonas have head gasket problems, and apparently, this is covered for 150,000 miles. Why do I have to pay for engine replacement?

Engine blew a rod without warning or service light indication. The vehicle is available for inspection. My two children and I were put at risk due to the nature of the engine failure and being able to safely navigate the vehicle off of the highway. The vehicle was inspected by the mechanic of the shop that towed the vehicle. No warning lamps or symptoms of the engine failure until it happened. Low oil was suspected but made no sense since the oil had just been changed a month prior and no leaks detected.

A few months ago we became aware that our Sedona was burning through coolant and oil very quickly. We began to monitor closely and were adding coolant and oil frequently. We did not see any oil leaking on the engine or driveway. We brought the car into the Cherry Hill Kia service center to get checked. We were aware of a recall involving coolant and oil and thought this could be related. I told the mechanic we were checking the coolant and oil every week because it would run low and the check engine light would come on. We would add both oil and coolant and the check engine light would go out soon after. The Kia mechanic told us we needed new radiator hoses and an alternator. I pressed the mechanic because I did not understand how that would affect the oil consumption. We paid for the diagnostic and oil change and took our car to another mechanic and they replaced the entire radiator and alternator. This was in October, 24. In January of 25 we were driving on a 45 mph road with no shoulder when the lights on the dashboard lit up and we began to lose power. The vehicle stopped and we could not even get the hazard lights to function. My children were in the car. The police had to be called to stop traffic so we could safely push the car off the road until it could be towed. The vehicle is currently at Burlington Kia and we have been informed we need a whole new engine. We have always been diligent about maintaining our cars. I have no doubt that this is the result of poor engineering and design and puts families like ours in danger. Please help us and by holding Kia accountable.

Driving at approx. 45 mph the engine locked up and failed causing the van to die and not be able to restart. There was no warnings, lights etc before failure. Luckily the road was empty to be able to navigate to the side of the road to avoid a dangerous situation. Should it have been a busy highway it would have put everyone at risk with a disabled vehicle not being able to move at speed. Kia Dealership investigated the failure and although there was lower oil and coolant level the manifold gasket test failed to meet the requirements for a Kia failure and remedy was a $9000 new engine.

Rod failure, was told there was fuel mixing with the oil and caused the oil to break down and cause complete engine failure while driving down the highway with my kids. Kia will not do anything about it. How can this be right. I know a lot of people with the same issues.

Complete engine failure, knocking like crazy, fuel smell in the oil, The shop said the fuel in the oil broke it down and allowed the motor to fail. We were driving down the highway when it happened with family and kids which was not safe at all. No warning message at all, no check engine light, the shop has inspected and said it’s failed. The kia dealership has said many of the Kia’s have been recalled for engine failure but not ours? But others with the same motor have been.

We were going down the highway when the engine suddenly stalled. We had to shift lanes during heavy traffic without assisted steering or braking and no way to accelerate. This almost caused an accident just to get the car off the main traffic lanes. We were able to coast out an exit where the car came to a stop and had to be pushed of the road. When trying to restart the engine, it immediately seized. There were no warning lights or any indicators before the incident. The engine had been running perfectly fine before with no abnormal oil consumption, overheating problems or any other issues. The car was towed to a shop where the next day a terminal engine failure was diagnosed and we were informed that the engine would have to be replaced for about $8,000. The failure mileage was approximately 128,000.

July 2021 family of 6 driving on vacation. 3 hours from home car started losing power. Dash lights were coming on and no lights were on at anytime before this. Vehicle had 68,000 miles at the time. Lost power would not accelerate for several minutes and car started smoking under the hood. Coolant was spraying everywhere. Family stuck on side of highway in middle of Pennsylvania and no exit for 15 miles. Had to walk to an unknown home to ask them to fill several bottles of water. Put water in the car. It would run about 5 minutes and overheat again. Finally got to a rest stop. Took to O'Reilly auto parts where we had new thermostat, coolant and fluid and other minor parts installed spending about $700. Drove 15 minutes car broke down again overheating. Trucker mechanic stopped to help but no luck. This was on a Sunday where everything was closed. We could not get a ride or a rental. Continued driving about 3 minutes at a time and constantly adding fluids made it to a hotel. Had to store the van for the week at the hotel. They agreed to keep it while we rented a van and went to Virginia beach. Van had to be towed home. Took to a garage near home where the mechanic said the heads needed replaced. Replaced head gaskets, head bolts. New thermostat, spark plugs, heli coil, coolant,oil and labor. They gave us a discounted rate of $2087.00. Drove home worked for few days and needed towed. Broke down again overheating on a main 3 lane busy road near home. This time repair shop said it would need a while new engine. While we paid $700 in parts on way to vacation. Had $1200 in car rental fees. $2100 in head gaskets shop repair fees. $600 in towing fees. And they were wanting $6000 for a new engine. I sat the van in my driveway for months paying the payments and eventually had to voluntarily repo at 70K miles. Car had 1 owner before us and car was regularly serviced. We had free service and oil for the first year we owned. Now being sued for the balance. Help!!!

After driving 3 miles on 2/1, the engine fan ran after the engine was turned off- which never happens. We called Kia for service but nothing was available for 2 weeks; all Kia dealers were similar. No check engine light was illuminated. My husband popped the hood, saw the coolant cap was open and the coolant fluid level in the normal range (slightly above the minimum line). Closing the cap, he test drove the car. Although driving fine, he took the Sedona to a shop where the hood was again popped- the coolant level was showing now above the max fill line, no coolant had been added; as no fluid was seen by the mechanic and since no check engine light was lit, an appointment was made to bring the car back for a full diagnostic. On 2/2/24, after driving 3 miles and making a turn, I thought I saw smoke. But, it was a rainy day so I thought it was condensation from the concrete. After 1 mile, again while slowing to turn, I thought I saw smoke again; I pulled down the window and smelled burning. At this point I was near my home and the check engine light now turned on. Since there was nowhere to safely stop, I proceeded to the front of my home and summoned my husband. He opened the hood and noticed smoke and extreme heat from the engine, but fortunately no fire. After a couple of days, we decided to tow the car to a shop for diagnostics instead of waiting 2 weeks for Kia- we were told the engine had failed. Stunned by the rapidity of these events, we contacted Kia Customer Support and towed the car to our Kia dealer. I have been told the head bolt stripped causing coolant to mix with oil and the engine to fail; the engine itself will cost $8,148 and, and, with ancillary repairs, the total repair will be over $12000. The car has 125k miles and has been fully serviced at Kia over 9 years, lastly 4 months ago which included coolant service. No check engine light was triggered until smoke and extreme heat were emanating from a blown engine, despite progressing degradation.
