2018 Kia Sedona — Known Issues & Recalls

While driving on the interstate, your van made a banging or tingling sound from the front engine area with no warning lights to alert you. You had just experienced a sudden loss of power going uphill when you heard the noise. The engine threw a rod (internal engine failure), and if you hadn't pulled over immediately, the engine could have completely seized while you were driving at highway speed. Repairs will require engine removal and complete internal rebuild or engine replacement.

Your engine developed a blown head gasket and cracked block between 64,000 and 72,000 miles, despite no warning lights appearing on your dashboard. You initially noticed antifreeze smell and took the car in for leak inspection, but the problem wasn't caught until the head gasket failed. The repair will require engine disassembly to replace the head gasket and address the cracked engine block.

While driving uphill on a busy highway, your engine suddenly began running at high RPMs and your check oil and check engine lights started flashing, making steering difficult and creating a serious safety concern in traffic. When you pulled over and checked the oil, the dipstick showed the engine was completely empty of oil. You were eventually towed to a mechanic who confirmed your engine had seized and needed complete replacement. Addressing this will require a full engine replacement, which typically involves removing the old engine and installing a new or rebuilt one.

Your 2018 Kia Sedona's engine started knocking and burning through oil despite regular oil changes. After adding oil the knock went away temporarily, but three weeks later the engine completely shut off on the highway with no warning lights or sounds. A mechanic diagnosed a seized engine with locked pistons that requires complete replacement at only 107,000 miles. The repair will involve a full engine replacement, though the original engine is no longer available.

Your head gasket failed, allowing coolant to leak into the engine, which caused the vehicle to break down on the interstate. The engine damage was severe enough that it needed to be completely replaced. There were no warning signs before the failure occurred.

Your engine failed at 108,000 miles. This 3.3-liter V6 engine has known issues, but Kia is refusing to cover the repair. You may need to pay out of pocket for engine service or replacement.

Your engine has failed completely and requires replacement. Your vehicle is currently at the dealership where it was purchased, dropped off on July 30, 2024, and you're waiting for the replacement engine to be installed.

Your engine failed at 108,000 miles due to a known rod issue with this engine model. This is a serious engine problem that can cause sudden failure while driving.

While driving on the highway, your dashboard lights suddenly came on and your engine shut off completely, leaving you without power steering. The engine wouldn't restart and had to be towed to a mechanic, who discovered the engine had seized due to lack of oil. Your owner reports that all routine maintenance was performed and documented, but the dealership denied a warranty replacement, claiming the engine showed sludge and was neglected—despite maintenance records. The owner believes the engine failure was caused by a manufacturing defect in the GDI engine that caused excessive oil burning with no warning signs. An engine replacement may be necessary to restore your vehicle to working condition.

While driving normally, your engine suddenly lost power and started using much more fuel than usual. You noticed a strong fuel smell inside the cabin and white smoke coming from the exhaust. This combination of symptoms suggests a serious engine issue that needs immediate diagnosis, likely involving the fuel injection system, engine sensors, or internal combustion problems.

Your engine has failed at 90,000 miles, and the dealer won't cover it under warranty because you're the second owner. You noticed your car was burning oil before the failure. Since other 2018 Kias have been recalled for similar engine failures, this appears to be a manufacturing defect rather than a maintenance issue. Fixing this will likely require engine repair or replacement.

Your check engine light keeps turning on and off intermittently. When the light is off, you may notice a lack of power and hesitation when accelerating (throttle lag). Your Kia dealership has identified that the CVVT Assembly and Oil Control Valve need replacement, with the possibility of full engine replacement if there's additional damage. The fix will involve replacing these valve components and possibly the entire engine depending on the extent of the damage.

Your airbag warning light came on in 2022 and was supposedly fixed under recall when the airbag control module was replaced. However, you were in an accident in August 2022 where the airbags failed to deploy, and the warning light has remained on ever since. A dealership later told you the entire passenger airbag unit needs replacement for $800+, but Kia refused to cover it under warranty, saying it's unrelated to the 2022 recall fix. The underlying recall issue involved the airbag control unit cover potentially contacting a memory chip, which could disable the airbags entirely. Fixing this will likely require replacement of the passenger airbag unit and possibly recalibration or replacement of the airbag control module.

Your airbag warning light keeps coming back on even after the dealer has replaced nearly every part of the airbag system nine times. The light typically returns within an hour of driving after each repair visit. This ongoing issue may require a complete diagnostic workup or potential replacement of the airbag control module or wiring harness.

Your driver's side door is stuck in the closed position because the electric motor that opens and closes it isn't working. You may not be able to open the door normally. The fix will likely involve replacing or repairing the door latch electric motor assembly.

Your car's paint is peeling off in areas. This is a cosmetic issue that doesn't affect how your vehicle operates, but it may expose the underlying metal to rust over time. The fix would likely involve sanding down the affected area and repainting it.

Your child pulled the second-row passenger seatbelt (next to the window) so tightly that it wrapped around their neck and became stuck. Turning the car off and on again didn't release it, so you had to cut the seatbelt with scissors to free them. The seatbelt retractor mechanism appears to have jammed and failed to allow normal release.

Your engine suddenly failed while driving, causing holes in the engine block and an oil leak that ignited a fire under the hood with no warning lights beforehand. Your husband lost power and had to coast to the roadside as flames appeared. Kia's service center indicated the engine likely threw internal rods, which damaged the block and allowed leaking oil to ignite when it contacted the catalytic converter. Repairs would require a complete engine replacement costing $12,000–$15,000.

Your engine suddenly failed while driving, causing all warning lights to illuminate and the engine to smoke and leak fuel. Multiple systems failed at the same time including power doors, steering, and acceleration, forcing you to have the car towed. This appears to be a recurring problem affecting multiple owners, suggesting a potential design or manufacturing defect that may require significant engine repairs or replacement.

Your engine suddenly shut off completely while driving with no warning lights or indication beforehand — just a clicking sound followed by the vehicle going dark in the middle of the road. A mechanic determined the engine is defective and needs to be replaced. The fix will require a full engine replacement rather than a simple repair.
