U0155 on Kia
Lost Communication with Instrument Cluster
U0155 on Kia vehicles indicates lost communication with instrument cluster. Au7o has documented this code across 1 Kia model — most commonly on Rio. This is a network communication code meaning a control module (usually the engine or body computer) has lost communication with the instrument cluster over the vehicle's data bus. Modern vehicles share information between modules over a network (such as CAN), and the cluster both displays data and relays messages. When messages from the cluster stop arriving, this code sets. You may see warning lights, dead or erratic gauges, missing displays, or other modules acting up. It usually points to wiring, power/ground, or the cluster itself rather than the engine. Typical repair costs on Kia range from $120 to $900, depending on the specific model and root cause.
Common Causes of U0155
- •Faulty instrument cluster
- •Loss of power or ground to the cluster
- •Damaged or corroded CAN bus wiring
- •Loose or corroded connectors at the cluster
- •Blown fuse feeding the cluster
- •Short or open on the communication bus
- •A different failed module dragging down the bus

- 12V Battery Drain and Intermittent Dead Battery from Telematics/Infotainment Sleep Issues2021-2023
Some Rio owners have experienced repeated dead batteries after the car sits overnight or for several days, despite the battery testing good initially. Reports point to parasitic draw from modules that do not consistently enter sleep mode, including infotainment, telematics, or body control functions. The result is a no-start condition, especially in colder weather or on vehicles driven short distances.
