2016 Kia Sedona

In Feb of 2023, my van had no known issues and out of nowhere it started making a terrible noise, every light in the dash came on, my power steering stopped working and then my engine shut off. I had it towed to a mechanic shop, they said it needed an engine. I had it towed to our local KIA dealership. They said it did not need an engine, it only needed a timing chain. That was $8000. We decided to get it done. 4 weeks later exactly from when we picked it up, I was on the interstate and the exact thing happened. I had it towed back to our local KIA. They stated it now needed an engine and it would be a used engine because they do not manufacture the engine anymore. It had over 60K miles on it and it would be $13K not including shipping or labor. We decided not to do this. After further investigation, this should have been under warranty the entire time and we never should have spent any money on it. This has been a terribly unreliable “family car”. I will NEVER buy a KIA again. My family is still suffering from paying $8K+ to have it “fixed”.

I have a 2016 kia sedona. Engines on the vehicle have been known to be bad and I already had 1 engine replaced under their extended warranty that covers to 150000 miles after a blown head gasket. I got a new engine 11/2024 however car overheats & coolant leak everywhere&bust hoses. I was told to replace radiator and all cooling/heater hoses, but video show coolant bubbling car still overheating. Replaced one loose hose under warranty. Car overheats again was told to replace relay switch for fan another. Dealer crash my car waited a month for parts and they never repaired damages to my bumper and airbag light. 2 month later car overheats again now coolant spraying into trunk and hose pop again now at heater core. There is no light notice of when car overheating tiil very hot. Or someone tells me my car is smoking by then it is followed by a loud noise and coolant leaking everywhere again. This time the overheating bust the heater core hose in my trunk and was spraying coolant all in trunk while I was getting ready to get of freeway. Very scary. I pulled over just in time for noise and coolant to leak out everything from resovoir again. This is my family car and have 5 kids under 18 and feel very unsafe now. Despite paying for everything kia suggest every 1-2 months they still fail to find cause of overheating and constant hoses breaking or coming loose after the pressure build up and I am scared this car will catch fire or stall one day with my children in car. Already noticed sometime its like car struggles to accelerate despite a supposed new engine but car been constantly overheating even after engine replacement and it also still causes sludge in hose& had 4 coolant flushes in a year and new hoses and now seems people working on car not sure what they doing because I was told I needed new heater hoses 2months later they didn't know my heater core was at back car so didn't replace so this hose burst despite kia recommendation to replace. Please help b4 it too late

The contact owns a 2016 Kia Sedona. The contact stated that while her husband was driving 50 MPH, the contact heard a knocking sound coming from the engine and the vehicle lost power. The contact was able to pull over to the right side of the road, turned off the vehicle for several minutes, restart the vehicle, and the vehicle worked as intended. There were no warning lights illuminated. An independent mechanic was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case; however, the case number was not available. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was 88,500.

In October 2024 we broke down on the highway outside of DesMoines, IA. The van slowed considerably in the midst of 11am traffic on I [XXX] from a lack of power, not from applying the brakes. Cars behind us had no warning, but no one hit us. The 4-way flashers and turn signals would not engage. There was no warning from the dashboard of a pending issue. Trent’s Garage in Clive, IA determined the main reason was an internal oil leak that damaged the alternator, which they replaced along with the right-side valve cover gasket. There was an earlier incident that I attributed to a service mistake. Shortly after Napleton Elmhurst Kia in IL serviced the vehicle in June 2023, it began to hesitate and become unresponsive while we were driving. There was no indication from the dash lights or from our garage floor that the engine was leaking any fluids or was low on oil, but I checked the oil at a suggestion from my wife. It barely registered on the dipstick. I added oil and the van ran fine. I now monitor the oil level regularly and add a quart of oil every 1000 miles. There is still no visible oil leak. Napleton Kia Service told me nothing could be done short of replacing the engine, and that I should change the oil more frequently (April 2025) than their original recommendation of every 5000 miles.

in June 2026 sever engine knocking at startup and during slight acceleration lead us to have vehicle inspected. there were no warring lights on and no other indicators of issues. An independent mechanic as well as a Kia dealer performed inspections and indicated a lifter bearing failure due to inadequate oil delivery. at the time the oil level was within range and within 3,500 miles since the previous oil change. Dealer indicated a complete engine replacement was needed due to the bearing failure and damage to the lifters.

I am writing to report an incident with my 2016 Kia Sedona, which experienced a sudden engine failure. The failure was diagnosed with engine codes P0014 and P0018, indicating camshaft timing and crankshaft correlation issues, consistent with internal engine failure and symptoms related to the known Theta II engine defect with Kia’s of that year, including metal debris and timing issues. For many of these Kia’s the warranty was extended to 120,000 miles. My incident took place at 120,600 miles. I have maintained this vehicle responsibly, and this issue occurred with little to no warning. Though I understand the mileage technically exceeds the warranty limit, the proximity to the cutoff and the nature of the failure suggest that the defect likely developed well before the warranty threshold. I contacted Kia to request goodwill coverage for an engine replacement or the associated repairs. I believe that other customers in similar situations have received assistance under goodwill policies, especially for issues tied to known manufacturer defects, unfortunately Kia declined to open a case on my behalf.
