U1110 on Kia
Network Communication Fault (manufacturer-specific; commonly Lost Vehicle Speed Message)
U1110 on Kia vehicles indicates network communication fault (manufacturer-specific; commonly lost vehicle speed message). Au7o has documented this code across 2 Kia models — most commonly on K5, Sportage. U1110 is a manufacturer-specific network (U) code, so its exact meaning varies by automaker. It generally indicates a data-bus communication problem; on several makes (such as Chrysler and Ford) it is associated with a lost or invalid vehicle speed message, meaning a module did not receive the expected speed data over the network. Loss of this data can affect modules that rely on vehicle speed, sometimes causing speedometer, cruise, or related symptoms. The specific definition should be confirmed against the vehicle's service information.
Common Causes of U1110
- •Wiring or connector fault on the communication bus
- •Faulty source module (e.g., ABS module sending speed data)
- •Loss of power or ground to a networked module
- •Corroded connector pins
- •Bus wiring short or open
- •Faulty receiving control module
U1110 on Kia by Model
Kia K5(1 issue)
- Infotainment Screen Blackout and Random Reboots2021-2025
The K5 infotainment system — both the 8-inch and 10.25-inch displays — experiences random screen blackouts, freezes, and spontaneous reboots. The screen may go completely black while driving, losing access to navigation, backup camera, and climate controls. Some owners report the system rebooting in a loop. The issue is typically software-related but can also be caused by a failing display head unit. Android Auto and Apple CarPlay connections can trigger or worsen the problem.
Kia Sportage(1 issue)
- Infotainment System Reboot Loop and Screen Freeze2020-2025
The infotainment head unit in 2020+ Sportages enters a continuous reboot loop or freezes on the splash screen, leaving the driver without navigation, backup camera, and climate controls (on models with touchscreen-only HVAC). The issue is caused by software bugs and insufficient system memory for the connected services. Firmware updates from Kia have improved but not fully resolved the issue. The problem often occurs after USB device connection or Bluetooth pairing.
