There is a continuous leakage of oil from my van even after the dealer replaced valve cover gasket . When I complained they said it was the leftover oil. After a month again I complained . Then they re-checked and said it is my car's timing cover reseal leaking . Again after few days I had to complain as there was a leak. I got the same standard reply of leftover uncleaned oil is the cause. Few weeks later I took the van to them and they said they thoroughly cleaned and there won't be any leak. I sent them pictures of oil drops underneth the car like I did on earlier occassions. On August 11th this year they checked the car after my complaint and said there was no active leak. On 30th of this month I sent them the pictures of leaked oil spots which they are going to check on 18th September!. Since I got my first appointment on January 19 2025 I took the vehicle to the dealer 5-6 times. In between I complained to them about failure of door locks and wiper blades. They said they were fine and had no issues. A week ago passenger side door lock stopped working often . I took to a mechanic store run by AAA. Their response after few days was that the electrical system was failing due to bad alternator as the battery got depleted. They recommended me to the dealer again. I was searching google and realised that an oil leak can cause alternator to go bad leading to electric failure and even fire accidents. On [XXX] I noticed red flashing sign of alternator and some other (?) after 2 minutes drive from home. So I immediately turned back and went home and parked the van in the garage and waiting for September 18 for an inspection by the dealer. Last week drove to St Louis from Lexington, after the dealer confirmed there was no oil leak. In all their reports they mentioned vehicle is in good health! Each time when I sent a picture of a leak I requested managers at the receiving desk to park at a clean place and check the leak which they never did.

THIS IS UNRELATED TO THE SAFETY RECALL FOR THE FUEL RAIL The electronic door locks fail, (mine are not fully automatic, but when you turn on the key you can hear the safety locks trying to engage before permitting the vehicle to move - they do not work. Worse even with the key, the doors will not consistently lock or unlock. Doors can become locked to the point that you can not manually open them, creating a fire hazard for occupants. Additionally, there is NO safety or emergency release on the back hatch. if you are inside when this locking aberration occurs, you must exit via a side (if it HAPPENS to be working) or front door (again, if it happens to be working. I fail to understand why this is not a major safety issue and why no recall has been issued. There are literally 1000s of such reports on various car forums. With at least one registered here: CS1603A Confirmed via independent service center. Records available upon request. No insurance inspection and no warning alerts occur.

Reported as far back as and paid for repair of both sliding doors staring in 2015-2021 doors at first would not open on button press no matter which button used key fob or inside vehicle had to force pull the handles to open and eventually to close. Just a week ago april 2021 while taking my elderly mother to store while parked after leaving the store, the passenger side sliding door stuck in the open position and no amount of force nor button push would close it. In march of 2021 I received notification from kia of limited warranty extension (wty018) which specifically lists power sliding door lactching for 2011 to 2014 sedona's. I reported the door not closing at all which happened on a saturday when parts was likely closing for the day and when I finally got through to them on monday dropped the car off to my same kia dealership that has done all of the repairs and place of purchase they looked at the vehicle and informed me they were not sure the roller was covered under the warranty and I would be charged $750 and only the the latch and motor of the door was covered (all parts of the same mechanism) I declined the repair being they wanted me to pay rented my own out of pocket rental for a week because I am an essential worker while I contacted kia corporate directly by phone with my issues and how rude they were trying to explain how parts of the door would not be covered the car is undrivable being the door remains open going into week two out of my own pocket I finally got someone from corp to acknowledge something is wrong and was told they would fix it in "good will" four days ago I am still without a car while they wait for part they needed and called back today to corp who called the dealer and somehow part came in "last night" but they can't pick up till monday to fix again I am without my car and work for the county tax admin office.

Took vehicle to dealership for recall, wiring harness. When done, the horn, left rear door lock switch and the radiator fans stopped working. All these worked prior to the recall work. And these items do work when bypassing with a battery, hooking them directly to power.
