2015 Kia Sedona engine problems

“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.”

“Was driving down the road with zero issues known, no check engine light, and only 114K miles. There was a sudden noise that was quiet so I turned down the radio, and then within 2 seconds or so a loud bang occurred, followed by a lot of smoke. I looked in the side mirrors and noted flames coming from underneath the van. Pulled over and got my family out.”

“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.”

“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?”

“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.”
