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?

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 last week of February I took my 2020 Kia Sedona at 67,500 miles into Kia Ferguson in Tulsa, OK to have them replace my High Pressure Fuel Pump which was covered under an extended warranty. When I received my van back, the battery was dead and the AC wasn't working nor the control knob.(it was stuck) I had to replace my battery, and that Friday Kia said they would take a look at it. When I went to pick up my van, they told me it was going to cost $1500 to fix, and that I was responsible. I called Kia consumer Affairs, and discussed this with them as well. To no avail, I am being held responsible. I took my van somewhere else however was quoted higher. I asked if after they fix it was there a possibility it still might not work and that it could be something else, and the gentleman said yes. I don't want to put all of this money to fix a problem, Kia may have inadvertently disconnected something that really just needed to be reconnected. This is a safety issue for me and my children, as I get weak when I am overheated, and it gets entirely too hot in Oklahoma during the summers. I didn't have any prior issues with my AC prior to them replacing my high pressure fuel pump.

Car seemed to be running as normal except for a slight rattle sometimes when starting. No warning lights, overheating etc. After listening to radio while parked, Car acted as if battery was dead. AAA couldn't get it started. Had it towed to dealership and was told it was a catastrophic engine failure.
