“On December 16, 2025 at approximately 0830 hrs. EST my wife attempted to start the above vehicle. There was an "odd" odor in the garage by the vehicle at the time. She was unable to start the vehicle, there were not functional lights and no other accessories were functional. I perfomed a test on the battery later in the afternoon using a battery testing probe, it indicated the battery was non-functional. At approximately 1515 hrs. EST I replaced the battery in the above vehicle.

“Adding to NHTSA Safety Issue ID # 11685509. The car was taken back to the dealership on 9/8/2025 and the maintenance department was showed were the Junction box that controls a lot of safety features could be the issue and why normal diagnostics tools used could not isolated the issue to it. Online research shows that this Junction box is a common issue and an undiagnosed issue with major safety issues. Actually the maintenance department had no clue as to were it was even located on a 2019 KIA Sonata. Please look into this issue. I am having mine replaced but it will take a week to do it. It maybe because of the unavailability because of quality fixing the issue.”

“Upon starting my vehicle after going to the grocery store, the ABS, ESC, Check Forward Collision-Avoidance Assist System, and Auto Hold warning lights illuminated. The cruise control was then inadvertently deactivated. When vehicle is started the Check Forward Collision error comes on. After a few months when entering the freeway and accelerating I received an error regarding unknown engine issue. Took vehicle to Kia dealership and was who diagnosed that the hydraulic electronic control unit (HECU) needed to be replaced. Manufacturer being notified, vehicle not repaired at dealer due to cost.”

“I received a safety recall letter from Kia America July 2023 and Dec 2024 and called Jerry Seiner Kia Salt Lake City and they will not help me. I then called Kia customer care number on the recall letter 800-333-4542 and it goes to roadside assistance and they cannot help me. I then called the USGOV safety hotline listed on the recall letter 888-327-4236 and that goes to Coach Elkhart. So the Kia customer care number is incorrect and the USGOV safety hotline number is incorrect and no one except me knows this? Zombieland America. Anyone out their know why the USGOV safety hotline number lists Coach Elkhart phone number? I have had 3 other people look to see how crazy this all is.”
