NHTSA Complaint #11607738 — 2025 KIA CARNIVAL

On July 19, 2024, my 2025 Kia Carnival SXP experienced a significant battery drainage issue, rendering the vehicle inoperable. The cause is currently unknown, but it seems to involve a parasitic electrical draw that drained the battery while the car was parked and turned off. This issue occurred despite no prior warning or indication of battery problems. Compounding the situation, the door locks, including the mechanical lock, were disabled, preventing access to the vehicle. Kia roadside assistance sent a locksmith, who had to jump-start the vehicle to restore operation. After the jump-start, I received warnings that multiple systems were inoperable, including critical safety and driver assistance features such as the integrated braking system, motor-driven power steering, and tire pressure monitoring system. These failures raise serious concerns about the vehicle's reliability and safety, as it became inoperable and inaccessible without warning, potentially leaving drivers and passengers stranded in dangerous situations.
