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

On [XXX], my vehicle overheated and started to leek coolant. This happened while driving at about 65 MPH with my family. No check engine lights came up just noted that the HVAC started to blow hot air and then the vehicle shutdown making difficult to break. I remembered that received a letter from Kia on May 26, 2014 that extended the warranty to 15 years / 180,000 miles for this type of issues - warranty number WYT039. I took it to a Kia dealership in Puerto Rico to get service and they diagnose the vehicle with the same issue as stated in the letter. However, Kia claims that they can't do the work because it is in Puerto Rico and I will have to take to USA mainland. I argue that federal law covers Puerto Rico for Safety Recalls and Warranty information and that they can discriminate for this.

In February 2024, while driving on the highway, the van overheated causing us to pull over. Upon opening the hood, it was found that coolant was boiling in the reservoir. After letting the vehicle cool down, I began driving it again. Once back on the highway I heard a loud pop followed by smoke. I immediately pulled over. Coolant had sprayed all over the exterior of the van. When trying to tow the vehicle, it was found that it wouldn’t start. The vehicle was towed home and sat until we received the recall from Kia at the end of May/beginning of June. Once the recall was received and we noticed the symptoms of the recall matched those of our van, we scheduled a diagnostic appointment with MidWest Kia in Wichita, KS. We received news from the dealership that Kia declined the request for repair due to hoses being broken and according to them, they are not covered by this warranty extension in the recall. We started researching and found that faulty head gaskets(the reason for the recall) can cause hoses to deteriorate and even break. We contacted Kia Motors and talked with them about this. They still denied the claim. The cost of the repair would be over $10,000. Ki has records of the phone calls made to appeal.

Kia sedonas have known headgasket engine coolant leak issue that can result in engine failure and is dangerous. Engine coolant leak had been confirmed by smell initially, as well as white smoke, low coolant in reservoir. Then took to 2 separate mechanics who both verified engine coolant leak. First said did not fix these. The 2nd mechanic refused to fix due to difficulty removing this particular engine to repair, would not touch it. Got letter in the mail from kia directly saying "warranty extension on 2015-2016 kia sedonas with engine coolant leak" "take to dealer if above symptoms, and will be diagnosed at no cost, fixed at no cost etc"... Kia of asheville, nc dealer, wanted money to diagnose despite showing letter. Paid them. They verified engine coolant leak w relationship to headgaskets. Now wants approx $1000 to "look into it more" and kia customer service is not supporting dealer to fix this known issue with 2015-2016 kia sedonas regarding coolant leak. My engine could have caught fire or seized if I had not been so careful with it and immediately stopped driving. I have evidence verifying this from independent mechanics as well as kia. There is a serious risk of death of driving these vehicles, where a major recall needs to happen immediately. Without coolant, loose headgaskets, engines overheat and get destroyed and mine happened suddenly, and luckily I was not on the interstate. Welch automotive franklin nc was the first mechanic to diagnose, then stamey perfromance franklin nc was the second one to confirm, paramount kia asheville nc was the most recent one who still has it and now is trying to give it back without fixing..... Oddly enough they recalled the 2015-2016 sorentos with the same motor and issues, but not sedonas...... I can add diagnosis from welch and stamey performance as well if needed, but this is kia saying the headgasket coolant leak from their own mechanic. Also have more evidence. Please investigate this. Thank you!!

2016 Kia Sedona 3.3L V6 Engine overheating due to head gasket failure and coolant leakage, which subsequently caused noxious fumes to enter the cabin of the car which is a health risk especially for people who suffer from asthma, chronic diseases, or other high-risk populations such as pregnant women or children. While travelling with my family of five (including three children), we noticed an intermittent smell inside the cabin of the car while the air-conditioning was turned on, which days later we realized were engine coolant fumes. There was no warning light or indication of head gasket failure with coolant leakage. We were all exposed to these engine fumes inside the cabin, which contain ethylene glycol, that likely caused two children to feel nauseous and an adult with diagnosed asthma felt headaches and shortness of breath. According to the CDC, breathing ethylene glycol vapors may irritate eyes and lungs (source: [XXX] ). Kia acknowledges that a coolant smell may be experienced in the 2016-2017 Kia Sorento’s vehicles equipped with the 3.3L V6 engine [XXX], which is the same engine that is equipped in the 2016 Kia Sedona. We confirmed the 2016 Kia Sedona experienced a head gasket failure from an authorized Kia dealership and repair shop.

Our 2016 Kia Sedona SX with the 3.3L engine was consuming engine oil very quickly and experienced overheating. It is available for inspection. One time when the engine overheated, my wife was driving on the highway during a very cold day and had to pull over to stop the car. She had both of our children with her. The engine failed a block test that was performed by an independent mechanic shop. It was also taken to a nearby Kia dealership, and found to have a cracked head gasket, which is the cause of the steel bolts pulling and destroying the threads in the aluminum engine block. Since the dealership said they had to pull the engine apart to inspect it, the engine CANNOT be put back together since the threads are destroyed. There was no indication light that the engine was consuming oil so fast and low. We did get warning light and message when the car was overheating. There was NO indication on the warning lights that oil volume was low.
