Two intermittent problems began about one year ago at approximately 43,000 miles (current mileage approximately 48,000): 1) Rearview (backup) camera intermittently fails. When shifting into reverse, the display screen goes black or the camera image freezes. This causes a loss of rear visibility while backing up, creating a risk of striking a pedestrian or object behind the vehicle. 2) Audio system intermittently produces loud static and distortion across all audio sources (AM/FM radio, Bluetooth, etc.). This distracts the driver and can mask audible safety alerts. Contacted a Honda dealership regarding recall coverage for these issues; the dealership stated this VIN is not included in the recall. Neither issue has been repaired. The vehicle is available for inspection upon request. These symptoms match the federal safety agency recall campaign 23V‑431 (Honda MOST communication coaxial cable recall — intermittent loss of MOST connection causing rearview camera failure and audio popping/crackling); the dealership stated this VIN is not included in that recall.

The infotainment system and back up camera screen went completely black. We took it to Howdy Honda since there was a the federal safety agency Recall 23V‑482 that they had fixed once before. Now though, they are saying the issue isn't covered by safety recall and that we have to pay $6900 to have it repaired. However this faulty camera system is a known issue. In addition to the recall, there has also been a class-action lawsuit filed Mar. 22, 2019 in the U.S. District Court for the Central District of California, owners of the affected vehicles report that the infotainment system – an integrated in-vehicle communication, navigation and entertainment system – behaves erratically, malfunctioning, freezing, and creating a safety hazard and distraction. This is exactly what happened with our vehicle. The defect caused safety-related systems (including backup camera functions) to fail. The defect also caused the entire center console to go black while the vehicle is in motion, and caused navigation and other dashboard features to shut down completely while in use. The lawsuit alleges Honda breached its own warranty by simply replacing defective parts with equally defective parts. This is exactly what they did with the first recall. And now they're trying to charge us $6900 to fix it.

COMPONENT/SYSTEM: The infotainment/audio head unit and instrument display, which communicate over the vehicle's MOST (Media Oriented Systems Transport) fiber-optic network via FAKRA connectors. The vehicle is available for inspection on request. FAILURE: While driving, the center display and Carplay screen spontaneously reboot and show "Network Communication Lost." During these events I intermittently lose the rearview backup camera and other display functions and navigation as well as communication. The failures are intermittent, happen more often over bumps, and sometimes at startup, and even during smooth road conditions. SAFETY RISK: Losing the rearview camera is a hazard when backing up, and having the instrument/infotainment display reboot while driving is distracting and removes information the driver relies on constantly. CONFIRMED BY A DEALER: Yes, repeatedly. The manufacturer issued a safety recall (Recall 23-047, "MOST FAKRA service cables"), which a franchised dealer performed in May 2024, replacing MOST network components. About 15 months later, the same defect returned; the dealer found the audio-unit connection was not secured, reseated it, and confirmed the wiring had proper continuity (ruling out rodent or wire damage). The dealer otherwise offered only workarounds - an aftermarket Bluetooth adapter and recording video of the failure - not a durable repair. The issue still persists. INSPECTED BY MANUFACTURER: The manufacturer-directed recall remedy was performed by the dealer; there has been no police or insurance inspection. WARNING MESSAGES: Yes - a "Network Communication Lost" message accompanies each reboot. The problem was present before and after the May 2024 recall and had clearly recurred by mid-2025. KEY POINT: This is a failed safety-recall remedy. Recall 23-047 was performed at about 29,000 miles and the same defect returned by about 36,700 miles - a failure within roughly 7,600 miles. It persists today.
