Kia will notify owners. For model year 2011 Sedona vehicles, Kia will instruct dealers to verify the ACU part number and, if necessary, install an extension wire harness kit between the ACU Connector and the Vehicle Harness Connector. For all other affected vehicles, Kia will instruct dealers to install the extension wire harness kit. The recall began September 28, 2018. Owners may contact Kia customer service at 1-800-333-4542.

My car started losing its lights one by one. I lost the front right light first, then yhe right back side light, and now the brakes lights. I replaced all the bulbs and still does not work. Then my car just cut off while driving with no notification. I towed it in to Mavis. They checked and said the battery was not keeping charge. I paid to replace the battery ,belt and alternator. Four days later my check engine light, battery indicator, airbag indicator, door indicator came on and still is on.
Electrical system, Service brakes, Aug 30, 2023
While driving down the highway the cars Hybrid warning system came on causing the car to lose all breaks and lose power. The component of the vehicle that failed is the HECU. Kia already did a recall for this but did not include the hybrids for the recall. This is very unsafe losing all breaking power, driving 65 mph down the highway with my children in the car! There was absolutely no warning, no check engine lights nothing. I had it towed to the dealership and upon them driving it, it also cut completely out and did it to the person at the dealership. This is going to cause someone to lose their life and when you call Kia, it’s the same run around that your year wasn’t included in the recall yet there was a whole lawsuit about this.

Here I explain the problem better, when the car is at a low speed, such as when parking, the gasoline engine starts and it starts to rev up to 6k RPM and after that it brakes and hits hard, this would be dangerous on the highway and another problem is that when accelerating it has a delay of 1-3 seconds, and I want to report this problem to see if there is any solution

I was driving down the highway going 75 mph and all of a sudden my car tells me pull over safely do not drive and it shut down while I'm driving. It never turned back on. It started smoking and you could see orange light coming through the vents. I was stuck on a [XXX] bridge for 4 hours and I missed court that day. I called Kia and they came to pick up my car. They said it was free because my car has been recalled but ever since they've had it, they stop answering my phone calls and emails and now they are trying to charge me 5000 to get my car back and fixed. Before any of this happened, I noticed an oil leak at the gas station but was unsure whether it came from my car or not.

Electrical system, Other or unspecified, Engine, Jul 6, 2022, fire
My car caught on fire while driving from somewhere near the engine. The fire was so severe that fire department nor my insurance company were able to determine cause of fire and I’d only had vehicle for 45 days, it was a single owner with no accidents and maintained its entire life up to that point. I am requesting someone to examine vehicle and tell me how this possibly happened.

I BEGAN TO CHANGE LANES TO BE ABLE TO EXIT THE FREEWAY AND AS I WAS APPROACHING THE EDITS STOP LIGHT THE MOVING HEHICLE SEEMED TO LACK MUCH POWER. I WAS LUCKY ENOUGH TO HAVE THE CAR ROLL FAR ENOUGH ON MOMENTUM TO GET ME OUT OF THE WAY OF A VERY BUSY ROAD. IT WAS A MIRACLE THAT THE CAR ROLLED TO THE SPOT IT DID BECAUSE THAT HAPPENED TO BE THE ONLY PLACE THE SHOULDER COULD FIT MY CAR. I HAD IT SENT TO KIA DEALERSHIP AND IT TOOK THEM ALMOST AN ENTIRE WEEK TO FINALLY HAVE AN IDEA OF WHAT THE PROBLEM COULD BE. ENGINE SEIZED AS THE MAJOR PROBLEM AND OFFERED TO REPLACE IT FOR ABOVE $8000! THE CAR ISN'T EVEN WORTH THAT MUCH! COME TO REALIZE THERE WAS A RECALL ON MY ENGINE SO I AM NOW WAITING UNTIL KIA TECH SUPPORT REACHES OUT TO MY MECHANIC FOR THE APPROVAL OR DENIAL. I BOUGHT THIS USED CAR ABOUT 30 DAYS FROM TODAY'S DATE WITH 80K MILES
