2015 KIA Sedona problems

ENGINE

The check engine light illuminated with diagnostic code P0018 (crankshaft/camshaft position correlation, Bank 2), first recorded on a scan XXX. The vehicle was taken to a franchised Kia dealership in [XXX] on XXX at 88,719 miles. The dealer performed an engine teardown and provided a written diagnosis on XXX: metal debris on the exhaust camshaft position sensor, damaged camshaft phasers, a sheared camshaft pin, and metal contamination throughout the engine. The dealer states the engine requires either a major timing-system repair or complete engine replacement. This failure mode can cause sudden loss of motive power while driving. There was no crash, no injury, and no fire. The engine remains disassembled at the dealership and is available for inspection upon request. The problem was confirmed by a franchised Kia dealer in writing. NHTSA previously examined loss of motive power in this 3.3L V6 engine family in PE23-019, which named 2015-2021 Kia Sedona vehicles with 3.3L engines as peer vehicles. Warning prior to failure: check engine light only. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STRUCTURE:BODY

Right side sliding became stuck in closed position. Door was not openable by inside nor outside door handles. Not openable by automatic means such as push button. This situation slowed egress and could be a safety issue during emergency evacuation. During repair, KIA mechanics informed me that the forward latch (not the rear latch) of the sliding door was mechanically locked in closed position. The latch had to be destroyed from inside of vehicle to release latch to open door to be able to repair.

VEHICLE SPEED CONTROL

Our 2015 Kia Sedona VIN [XXX] developed CAN Bus fault codes U0001 U0100 U0101 rendering it completely undrivable following an incomplete warranty extension repair under WTY019 by Kia of Des Moines on [XXX] RO# [XXX]. The power sliding doors have been a persistent safety concern. The incomplete warranty extension repair left the sliding door not closing properly creating a safety hazard. The vehicle subsequently developed CAN Bus communication faults making it completely undrivable. After 28 days at Kia of Des Moines from May 4 to June 1 2026 under RO# [XXX] the CAN Bus fault was never diagnosed or addressed. The power sliding door still does not function after two warranty extension repairs. Upon retrieval June 1 2026 the vehicle continues to exhibit active CAN Bus warnings BDS warning lights flickering humming sound and rough driving. We believe the sliding door safety issues and CAN Bus failure are directly connected and represent a safety concern for other 2015-2017 Kia Sedona owners.

POWER TRAIN

ENGINE

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.

ENGINE

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 AND ENGINE COOLING

The contact owns a 2015 Kia Sedona. The contact stated that while driving at an undisclosed speed, the engine overheated. No warning lights were illuminated. In addition, the thermostat gauge indicated that the engine was overheating. The vehicle was taken to the dealer, where it was diagnosed with a cracked head gasket. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was informed that the repair was not covered under warranty because the mileage was over the limit. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 182,000. The VIN was unavailable.

ENGINE

The auto will go into safe mode when driving on the highway. You have to try to get to the side of the road without getting run over. This is a recall for most Kia's, but the dealer said my year car is not one of them. But it is doing the same as the ones under recall.

ENGINE

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.

UNKNOWN OR OTHER

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.

All of a sudden my vehicle has started consuming large amounts of oil. My wife was driving with my two small children when a check engine light went on and she pulled over and there was no oil left in the engine! i am unsure of the scale of the problem or if any significant damage has occurred. I worry that the car is at 149k that I will go over the 150k and be out of luck for a recall claim. I know that this was a complaint with other kia engines, but the 3.3 GDI Lambda seems to have the same issue. Please take care of it!

ENGINE

In 2021 we purchased the van and within hours the motor blew. The car dealer had the motor rebuilt and it has been good until recently. It seems the head gasket is blown as it’s using coolant and blowing white smoke. It’s also burning oil. This should not happen every couple years

EXTERIOR LIGHTING

Low Head Lights do not work. High beams and fog lights work. This seams to be a KIA problem across makes and models. Why has a recall not been issued?

NHTSA complaint #11635354 — an unverified report by a vehicle owner.

ENGINE

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.

ELECTRICAL SYSTEM

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

When driving on freeways and using my cruise control….. If I need to use my brakes to disengage cruise control when traffic slows and then use the “resume” feature on the C.C. my vehicle continues to accelerate until I shut the cruise off and reset it. If I am resuming to say 65 MPH I can reach 85 MPH in a couple seconds. This happens more than 50 % of the times I use my C.C. As I continue to age and my reflexes slow, this issue becomes a safety issue for me.
