2015 Kia Sedona electrical system problems

“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.”

“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.”

“Car engine overheated without any warning indicating that it was overheating. It just started smoking. Car is available for inspection upon request. Our safety was put at risk because in 95-degree weather, warm air was coming from AC when car sat idle. The root of the problem has not been confirmed by the dealer. Vehicle pictures were sent to insurance. No warning appeared before failure.”

“July 2021 family of 6 driving on vacation. 3 hours from home car started losing power. Dash lights were coming on and no lights were on at anytime before this. Vehicle had 68,000 miles at the time. Lost power would not accelerate for several minutes and car started smoking under the hood. Coolant was spraying everywhere. Family stuck on side of highway in middle of Pennsylvania and no exit for 15 miles. Had to walk to an unknown home to ask them to fill several bottles of water. Put water in the car. It would run about 5 minutes and overheat again. Finally got to a rest stop. Took to O'Reilly auto parts where we had new thermostat, coolant and fluid and other minor parts installed spending about $700. Drove 15 minutes car broke down again overheating. Trucker mechanic stopped to help but no luck. This was on a Sunday where everything was closed. We could not get a ride or a rental. Continued driving about 3 minutes at a time and constantly adding fluids made it to a hotel. Had to store the van for the week at the hotel.

“The brake lights went out. The bulbs were replaced. The fuse was replace and there still no lights. The top led brake light works, but lower lights on each side are out. I don't know if the brake switch is the problem when the upper led works. I have researched the issue and discovered that this is a xommon kia issue with many models. When a Google search is conducted for "kia no brake lights it comes up with other people that have the same issue with multiple models."”
