Complaint Summary

VISIBILITY/WIPER

Owner Narrative

My 2021 Honda Pilot has a recurring electrical/network communication failure that causes “Network Communication Lost” and “MOST Net Off” messages to appear on the infotainment screen. When this occurs, the infotainment system malfunctions, audio becomes unavailable, and the backup camera display is lost without warning. The problem is intermittent, unpredictable, and has occurred numerous times. The loss of the backup camera is a serious safety concern because it occurs while the vehicle is otherwise operating normally. During reversing, rear visibility is reduced, increasing the risk of striking another vehicle, pedestrian, child, cyclist, or object. The error messages and loss of infotainment functions also create driver distraction and raise concerns about the reliability of the vehicle’s electronic systems. I reported the issue to an authorized Honda dealership multiple times. They recommended replacement of the audio/display unit, and I paid for the repair. However, the same failure returned. The dealer later advised that the root cause may involve wiring, MOST network components, or another electrical defect and estimated approximately $3,000 in additional repairs. Despite multiple visits and approximately $983.29 in diagnostic and repair costs, the defect remains unresolved. Honda Service Bulletin 20-058 describes similar MOST bus symptoms, including communication errors, loss of audio, infotainment malfunctions, and multimedia network failures. My vehicle exhibits the same symptoms. Because the dealer-recommended repair failed, the problem appears to involve the vehicle’s electrical communication network rather than a single component. This recurring defect affects the backup camera, infotainment system, and other electronics relied upon for safe operation. I believe it may affect other 2019–2021 Honda Pilot vehicles and may represent a widespread safety defect. I request NHTSA investigate to determine whether a recall / other corrective action is warranted.
