U0155 on Chevrolet by model: symptoms, diagnosis and fix
The 10.2-inch infotainment touchscreen in the Bolt EV develops ghost touch inputs, screen flickering, unresponsive areas, and random screen blackouts. The screen registers phantom touches that change radio stations, adjust climate controls, or activate features without driver input. The issue is caused by a failing digitizer layer in the touchscreen or a loose ribbon cable connection behind the display. Hot weather and direct sunlight on the screen exacerbate the ghosting behavior. The issue affects both the original infotainment system and the updated system in 2020+ models.
Common Symptoms
- Screen registers touches that did not happen
- Radio station changes by itself
- Climate controls adjust without input
- Screen flickers or goes black intermittently
- Touchscreen unresponsive in certain areas
- Ghost touches worse in hot weather or direct sun
How to Fix
Perform a system reset by holding the Home and Fast Forward buttons simultaneously for 10 seconds. If ghosting persists, the display panel needs replacement ($500-$1,000 for parts, $200-$400 labor). A loose ribbon cable behind the display can sometimes be reseated without replacing the entire screen — ask the technician to check this first ($100-$200 diagnostic). Some owners have resolved minor ghosting by installing a tempered glass screen protector, which insulates the digitizer from temperature-induced phantom touches.

Frequently asked questions
What does U0155 mean on a Chevrolet?
U0155 stands for "Lost Communication with Instrument Cluster." 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. On Chevrolet it is documented across 1 model: Bolt EV.
What are the most common causes of U0155?
The most common causes of U0155 are: 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.
