2025 Kia Carnival

On or around [XXX] the rear occupant sensor warning light came on. We scheduled a service appointment with the dealership for 7/15/25 at 7:00 a.m.. We were informed later that morning that it was a defective module that could affect the air bags and it wasn’t safe to drive the car. It is 7/26/25 and we still wait on the part. Yesterday we were told by the service department that they didn’t know when the part would be available, it is back ordered due to the number of vehicles with the same issue. While our car waits at the dealership we got an email from Kia Connect giving us a 12 volt battery discharge warning. We don’t know if this is related or not but when looking online we found several people with that same problem as well. Our mechanic agreed that the 12 volt battery should not be discharging that fast due to just not being driven. The car sits at Russ Darrow Kia in Madison WI where parts and other information should be available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is the second time, while I was driving that the car would not want to pick up speed and shuddered. The engine light came on again. And stayed on this time. I brought it back to the Kia dealer. They ran a diagnostic. They first wanted me to pay the cost. It is under the warranty. Now I am waiting for the parts and was told to not drive my car until it gets repaired. No loaner was offered. They said to drive it home and they will contact me.

While I was driving on a highway, my vehicles "check engine" and "batter" lights were illuminated and a warning came across the car screen that said something along the lines of "Battery Management System Failure" and then "Powertrain failure". The car was not able to accelerate by pressing the gas pedal, and the heating/cooling features within the car stopped working. I quickly changed lanes to get to the far left shoulder of the highway, putting other cars at risk of my car that was slowing down to 50mph as I was getting over. When I would press on the gas pedal, nothing would happen. The car did remain on. When the dealership received the car the next morning they conducted what they referred to as a recall, but KIA refers to it as a "Service Action" - SA617 MCU DTC Logic Improvement. This requires a simply software update, which the dealership conducted, and the car was then working just fine, with no issues that I had indicated above. The dealership was Greenway KIA of Rivergate, 1526 Gallatin Rd North, Madison, TN 37115. The warning lights in the car illuminated about 5 seconds before the car was no longer able to accelerate due to the powertrain failure. In talking about the problem with a KIA representative, it was communicated that KIA has looked into this and it didn't pose any serious problems, so they left it as a "Service Action" item, not a recall.

The vehicle's battery drain after turning off and cannot restart. It can cause to stall the vehicle on road. Kia Connect sent "Our backend team has determined that a TSB ELE341 (Network Reset) is needed to refresh your vehicle’s connection to the Kia Connect servers. To resolve this, please contact your preferred official Kia dealership to schedule an appointment and mention TSB ELE341 for the network reset." Took the vehicle to a Kia dealer's service; they reset, but problem remains. I just received from Kia"Dear [XXX] , This is nothing that we can troubleshoot. You will have to wait for your appointment to have them handle the issue. Thank you Sincerely, Kia America INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at highway speeds the exterior and interior lighting/electrial system shut down completely. My headlights shut off, as well as all electrical/lighting inside the vehicle for approximately 1 minute before turning back on as if I had turned the car off and restarted it. I have a low tire pressure warning that comes on when the car is started, and it came on again as if my car had just started, while I was still driving. This poses a safety risk to myself and other drivers depending on the headlights for visibility. The incident did not cause my vehicle to stop driving although I did break due to the sudden loss of all electrical components.
