2015 KIA Sedona electrical problems

ELECTRICAL SYSTEM

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. They agreed to keep it while we rented a van and went to Virginia beach. Van had to be towed home. Took to a garage near home where the mechanic said the heads needed replaced. Replaced head gaskets, head bolts. New thermostat, spark plugs, heli coil, coolant,oil and labor. They gave us a discounted rate of $2087.00. Drove home worked for few days and needed towed. Broke down again overheating on a main 3 lane busy road near home. This time repair shop said it would need a while new engine. While we paid $700 in parts on way to vacation. Had $1200 in car rental fees. $2100 in head gaskets shop repair fees. $600 in towing fees. And they were wanting $6000 for a new engine. I sat the van in my driveway for months paying the payments and eventually had to voluntarily repo at 70K miles. Car had 1 owner before us and car was regularly serviced. We had free service and oil for the first year we owned. Now being sued for the balance. Help!!!

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."

OVER THE PAST COUPLE OF MONTHS OUR LEFT TURN SIGNAL BEGAN ACTING UP. YOU WOULD TURN IT ON, AND IT WOULD EITHER SHOW NOTHING, OR SHOW THE RIGHT TURN SIGNAL ON. YOU WOULD HAVE TO TURN IT OFF AND ON SEVERAL TIMES TO GET IT TO WORK CORRECTLY. WE HAVE TAKEN IT IN FOR REPAIRS AND WAS TOLD IT NEEDED A NEW SWITCH. WE HAVE OWNED SEVERAL VEHICLES OVER THE PAST 35 YEARS AND NONE OF THEM HAD THIS ISSUE, AND MANY WERE DRIVEN NEARLY 200,000 MILES OR MORE. THIS ALL OCCURRED WHILE NORMAL OPERATION/DRIVING OF THE VEHICLE.

ON MULTIPLE OCCASIONS MY HEADLIGHTS WILL TURN ON OR OFF WHEN USING TURN SIGNALS OR JUST HITTING A BUMP. THIS IS EXTREMELY DANGEROUS AS I LIVE IN A RURAL AREA WITH NO STREET LIGHTS.

TAKATA RECALL: OUR 2015 KIA SEDONA'S WHEN IN MOTION OR STATIONARY, THE TURN SIGNAL COMPONENT DOES NOT SIGNAL THE DIRECTION WE HAVE SELECTED. WHEN I CHOOSE LEFT TURN IT SIGNALS RIGHT TURN. I HAVE TO PLAY WITH THE TURN SIGNAL LEVER ABOUT 10 TIMES BEFORE IT MAY OR MAY NOT SIGNAL THE PROPER DIRECTION. THIS IS EXTREMELY DANGEROUS AS THE CARS AROUND US THINK WE ARE PLANNING TO GO RIGHT INSTEAD OF LEFT EACH INTERSECTION. PLEASE ISSUE A RECAL ON THESE TURN SIGNAL COMPONENTS FOR 2015 KIA SEDONA MINIVANS.

PASSENGER SIDE SLIDING DOOR GRINDS WHEN ATTEMPTING ELECTRONIC CLOSURE. SOMETIMES IT DOESNT CLOSE COMPLETELY. ON THIS OCCASION, DOOR WAS COMPLETELY CLOSED, NO DOOR LIGHT ON, AND WHILE DRIVING ON THE HIGHWAY THE DOOR ELECTRONICALLY OPENED WHILE AT SPEED. OUR 2 YEAR OLD CHILD WAS IN HIS CAR SEAT ON THAT SIDE PROVIDING A LIFE-THREATENING SITUATION WITH THE OPEN DOOR. TOOK IT TO THE DEALERSHIP AND THEY SAID THE MOTOR NEEDED TO BE REPLACED, BUT EVEN IF THE MOTOR WAS FAULTY, UNDER NO CONDITIONS SHOULD THE DOOR OPEN WHILE AT SPEED. THE MANUAL SPECIFICALLY STATES THAT THE DOOR WILL NOT OPEN WHEN OPERATING OVER 5MPH, AND YET, IT DID.

ABOUT 2 YEARS AGO I TOOK MY VEHICLE TO THE SERVICE DEPARTMENT TO GET THE A/C HEATER CONTROL UNIT REPLACED UNDER FACTORY WARNING, THIS WAS AT 70,000 MILES, THEN AT ABOUT 130,000 I HAD TO GET IT REPLACED AGAIN, ONLY THIS TIME IT WAS NOT UNDER A FACTORY WARRANTY THE REPLACEMENT PART COSTS FROM $1200 TO $1500. I ENDED UP REPLACING IT MYSELF AND AS I BEGAN TO REPLACE THE UNIT I NOTICED SOMETHING DISTURBING. THE A/C POWER BUTTON HAD MELTED AND BURNT, THE CONNECTORS WERE NEVER REPLACED THE FIRST TIME KIA REPAIRED THE A/C CONTROL UNIT UNDER WARRANTY. I THEN KNEW WHAT THE PLASTIC BURNING SMELL WAS WHEN MIGHT A/C WAS TURNED ON. I ASKED THE KIA SERVICE TECHNICIAN WHY DOES THIS KEEP HAPPENING HE TOLD ME IT WAS BECAUSE I USED THE CAR FOR UBER AND THE SYSTEM WAS NOT DESIGNED TO BE RAN AS MUCH AS I DRIVE THE CAR, THE PICTURES ARE ATTACHED. IN APRIL OF THIS YEAR AT ABOUT 201,232 MILES MY FRONT BLOWER MOTOR STOPPED WORKING AS I WENT TO GET IT REPLACED, I NOTICED THE SAME ISSUED WITH THE CONNECTOR. THE PLASTIC CONNECTOR BURNT OUT AND SHORTED THE BLOWER MOTOR, AND JUST WHEN I THOUGHT THAT WAS A COINCIDENT, I UNPLUGGED THE BLOWER MOTOR RESISTOR TO CHECK IT AND FOUND THAT CONNECTOR THERE TOO HAD BEEN MELTING AND BURNING. I AM INFORMING YOU, OF THIS PROBLEM BECAUSE IT KEEPS HAPPENING IT SEEMS ABOUT EVERY 70K TO 80K MILES ON THE A/C CONTROL UNIT BECAUSE I AM ABOUT TO PUT A 4TH A/C CONTROL IN MY VEHICLE, I AM FEARFUL OF FIRE HAZARD/POTENTIAL THIS MAY CAUSE. THIS IS GETTING EXPENSIVE TO CONTINUE TO HAVE TO REPLACE/REPAIR PARTS BECAUSE THE CAN'T WITHSTAND HEAT. THE FIRST FOUR PICTURES ARE FROM THE A/C CONTROL UNIT THE LAST PICTURE IS FROM THE BLOWER MOTOR.

THIS STARTED WITH 60K MILES ON MY CAR. DEALER SAYS IT WILL COST ME $2200.
