2018 Kia Sedona Service and Repair Manual
Kia wrote the service data for the 2018 Sedona against this exact year, engine and trim range, so what you work from is the number Kia published for your minivan rather than a near-enough figure carried over from an earlier or later Sedona.
Engines covered
- 3.3L V6 — DOHC, naturally aspirated, gasoline
Body styles covered
- 4-door mini passenger van
Trims covered
- EX
- L
- LX
- SX
- SX Limited
- SXL
Known issues on the 2018 Sedona. One recall is on federal record for this model year, and it concerns the air bags: the Air Bag Control Unit (ACU) cover may contact a memory chip, and air bags that do not deploy as intended can increase the risk of injury in a crash. Owners have filed 62 complaints for the year and Kia has issued 48 technical service bulletins.
From tracing an air bag warning light back through the restraint system to keeping the 3.3L V6 on its published service intervals, it holds you to Kia's own procedure and the right specification for your 2018 Sedona.
Kia Motors America (Kia) is recalling certain 2015-2018 Kia Sedona vehicles equipped with a power sliding door (PSD). The PSD may not auto-reverse when its closing is obstructed.
If the door closes on an occupant, there is an increased risk of an injury.
Kia will notify owners, and dealers will reprogram the PSD module software, free of charge. The recall began on June 18, 2018. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC164.
Kia Motors America (Kia) is recalling certain 2017-2019 Sedona, Soul, Soul EV, 2017-2018 Forte, and 2017 Forte Koup vehicles. The Air Bag Control Unit (ACU) cover may contact a memory chip on the printed circuit board and damage the electrical circuit. Circuit damage may result in deactivated air bags that will not deploy in a crash.
Air bags that do not deploy as intended can increase the risk of injury in a crash.
Dealers will inspect the ACU, and either update the software or replace the unit, as necessary. Repairs will be performed free of charge. Owner notification letters were mailed March 21, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC226.
Kia Motors America (Kia) is recalling certain 2015-2018 Sedona vehicles equipped with manually-adjusted front passenger seats. Over time, the Occupant Detection System (ODS) wiring harness located underneath the front passenger seat may break from the seat being occupied.
If a child is in a child seat in the front seat, a broken ODS wiring harness will not prevent the front passenger air bag from deploying in the event of a crash, increasing the risk of injury to the child.
Kia will notify owners, and dealers will remove the wire harness clip to prevent the wiring harness from breaking. If the harness is found damaged, the front passenger seat cushion will be replaced. These repairs will be performed free of charge. The recall began March 19, 2019. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC175.

My Daughter was driving my Kia Sedona Van - distracted and on wet roads ran into a firehydrant and pole. During the accident, the Air Bags did not employ. The Passenger fell forward and broke the windshield with her head, leading to a Concucussion. We are thankful for two Children who are alive after this accident. We are disappointed tho that the airbags didnt protect our child more.
There was a fire under my minivan as my husband was driving it, creating smoke and flames. He lost power to the van and had to coast to the right side of the highway where he came to a stop with the flames occurring. This is the family vehicle and I have small children. We had no warning lights or any indication that there would be a fire in my vehicle as the van had been running smoothly, and I had kept up with all recommended maintenance (see Carfax report). On July 31st, I was told by Kia
Our 2018 Kia Sedona SXL caught on fire in the engine compartment while driving. IT almost killed my wife (driver) and my 4 year old son. Car had been driven only 2 blocks after picking up my son from daycare. The car started to produce black smoke incessantly from the engine compartment that made visibility almost impossible. Bystandards were waving with their arms up and trying to warn my wife and she managed to stop in a parking lot and run away with my son. Car got very hot. Despite of keepin
10 mile drive to town. On return home, smoke began pouring from the engine compartment. Within 3-4 minutes flames came from grill area, and within 15 minutes entire car was engulfed in flames.
Vehicle was idling when smoke and fire started presumably from the engine causing a car fire. We are the insurance company that paid for the car and Clearcover Insurance is now the owner.
Head gasket blew and caused coolant to leak into the engine. We broke down on the side of the interstate. Our vehicle sat at the dealer for 5 months awaiting a new engine to be put in. No warnings beforehand.
My [XXX] son pulled the seatbelt so tight it got wrapped around his neck. When I pulled over to unbuckle it, it was stuck. I turned the car off and on again to try and loosen it, but it didn't work. In the emergency, I had to cut the seatbelt with scissors. It's the passenger seatbelt in the second row, next to the window. I reported the incident to Kia in Puerto Rico by phone. They never called me back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Engine in my 2018 Kia has failed. This should be covered under warranty as van only has 90k miles on it but because I am the second owner they are telling me it is not covered. Several other 2018 Kia’s have already been recalled for engine failure. My car was burning oil. This is a manufacturing issue and I am very stressed about paying to get it fixed out of pocket.
WE ONLY HAD OUR VEHICLE 5 MONTHS AND MY HUSBAND WAS SITTING IN TRAFFIC DURING A SNOWSTORM AND THE WIPERS STOPPED WORKING. WE TOOK THE VEHICLE TO THE DEALER AND THEY TOLD US IT'S NOT A MANUFACTURER'S DEFECT SO WE WOULD HAVE TO PAY $507 OUT OF POCKET TO REPLACE THE WIPER MOTOR. THEY CLAIM THAT HAPPENED FROM SOMEONE MOVING HEAVY SNOW OFF THE WINDSHIELD WITHOUT CLEARING OFF THE WINDSHIELD FIRST. MY HUSBAND HAS AN ICE SCRAPER AND HE TOLD ME HE USED IT, NOT TO MENTION, HE KEPT THE HEAT ON THE WINDOW T

In 2022, our airbag light came on. On 5/10/2022 am Airbag recall was issued and it was fixed. The airbag computer/module was fixed.
