The Information screen goes blank. Then at that point the backup camera will not show on screen when backing up. Creating a blind spot and hazard

This complaint is being filed regarding a FAILED REMEDY for the federal safety agency Safety Recall 23V‑431 (Honda Campaign ZEM) on my 2021 Honda Pilot Touring. Although the vehicle history shows that the recall repair for the MOST fiber-optic wire harness was previously performed, the authorized remedy has completely failed to fix the safety defect. The central infotainment dashboard screen regularly displays a "Network Connection Lost" error message before freezing or shutting down entirely. This failure causes an immediate, total, and unpredictable loss of the backup camera display while the vehicle is in operation. Because the backup camera is a federally mandated safety feature, its random failure creates an active safety risk for myself, my passengers, and pedestrians during reversing maneuvers. Honda customer service has refused to provide further diagnostic or repair assistance because the recall is already marked as "completed" in their database. However, the safety hazard remains active and unresolved. I request that the federal safety agency investigate this failed remedy and compel Honda to provide an effective, lasting repair for this defective system.

The electrical for the infotainment system cuts out and the rear camera is no longer on the screen, it will cause loud popping while driving as the MOST Net system is failing. There is also poor gas mileage and reads the gas tank contents incorrectly while displaying incorrect MPG typical with the fuel pump recall for this generation of Honda Pilot, but both of these recalls removed my specific year shortly after they were announced.

The infotainment system and rearview backup camera malfunction continually. While driving or attempting to reverse, the infotainment system frequently shuts off entirely and loses its fiber optic network connection. When it attempts to reboot and turn back on, loud popping and crackling noises emit from the vehicle speakers. Additionally, the backup camera regularly glitches and displays a message stating that the system is "Too Hot," causing the rearview monitor to go entirely blank. These issues are especially severe on hot days.This creates an immediate safety hazard, as it unexpectedly eliminates rear visibility while backing up, increasing the risk of a collision. It also causes distracted driving conditions due to the sudden, loud audio popping and screen blackouts. This failure mimics the exact symptoms outlined in Honda's active MOST Bus Coaxial Cable recall, yet my vehicle is experiencing the same severe safety defects. Rear view camera does warn it no longer works due to heat. No inspection done as of yet but plan on taking it to dealership.

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 the federal safety agency investigate to determine whether a recall / other corrective action is warranted.

My 2021 Honda Pilot has a failing rearview camera caused by the identical MOST network coaxial defect described in the federal safety agency Campaign 23V431000, but Honda drew the recall population too narrowly and excluded my VIN.

The infotainment screen blacks out completely and sporadically, but as of recent, almost daily. Sometimes for about 3-5 minutes. When this happens, the rearview backup camera is completely disabled, creating a blind-spot safety hazard, violating Federal Motor Vehicle Safety Standard 111. This issue directly impacts back over prevention and driver visibility. I have multiple videos of this occurring. In 2023, a Honda dealership performed the MOST Bus/FAKRA connector safety recall on this vehicle. That manufacturer recall remedy has FAILED, and the exact same safety defect has returned. I did schedule the vehicle for a formal diagnostic inspection at a Honda dealership this Friday to pull the network communication error codes. There were no warning lamps or warning messages prior to the system blacking out.

Infotainment system doesn't work, including maps, and backup camera. I have read this is a common problem, but Honda isn't doing anything about it.
