2020 Honda Odyssey: backup camera failure

Filed Oct 14, 2026 · Visibility · VA

Associated Recall: 26V‑423 (Rearview Camera Cable Harness) Description of Safety Defect & Insufficient Recall Remedy: I am filing this complaint to report that the current manufacturer remedy for recall 26V‑423 is insufficient due to a related, pre-maturely failing structural component that Honda is failing to address. The rear window seal for the glass sliding door (Honda Part # 73220-THR-A01) on this generation of the Honda Odyssey is made of a defective rubber material. On my vehicle, this seal is prematurely disintegrating into small shreds [Optional: See attached photos]. This degraded seal allows water to seep directly into the rear camera housing area. While the recent recall may have replaced or repaired the immediate rearview camera wiring, the ongoing water intrusion caused by this disintegrating window seal will inevitably cause the new camera components to fail again. Fixing the camera without addressing the root cause—the failing rubber seal letting water in—makes the current recall remedy entirely temporary and insufficient. the federal safety agency needs to investigate part number 73220-THR-A01 and compel Honda to issue an expanded recall to replace this seal with a higher-quality, weather-resistant material to prevent future safety failures of the backup camera system. I have already reported this issue to the service advisor on Oct 12 2026 at ourisman honda of woodbrige VA and they said they cannot help me with it and recall is not addressing the windshield molding on the rear sliding door of the minivan.

I went to the dealership today for my recall on the backup camera where my screen goes black in reverse. I also told me my dash lights had come on and could like lane keeping assistance, adaptive cruise control and blind spot warning. Dealership then tells me it is a faulty internal camera in the windshield and wants to charge me $2K. Is this not a recall since it happens to a significant amount of honda odysseys and pilots? Please make this a recall as it is not safe to drive my van anymore and should be apart of the recall I took it in for.

I own a 2020 Honda Odyssey with approximately 73,000 miles that has experienced recurring infotainment and electrical system failures. The vehicle has undergone two prior repairs related to the Fakra connector issue, but the problem continues to occur. During the failure, the infotainment screen becomes inoperable, audio functions are affected, and the rearview backup camera becomes unavailable or unusable. The issue appears to be intermittent and is often triggered during or after rain. In addition to the infotainment failures, I have experienced key fob recognition issues requiring the key to be placed near the start button to start the vehicle. There is also static through the speakers, particularly when turning the steering wheel. The vehicle has been taken to a Honda dealership multiple times for this concern, and dealership personnel have witnessed the malfunction. Despite two previous repair attempts, the issue persists. Because the failure affects the operation of the rearview camera system, which is a critical safety feature, I am concerned about the safety of the vehicle and whether the prior repairs adequately addressed the underlying defect. I am submitting this complaint because numerous other Honda owners have reported similar recurring failures involving the infotainment system, Fakra connector repairs, backup camera operation, and related electrical concerns. I request that the federal safety agency investigate whether there is a broader defect affecting these vehicles and whether previous repair procedures are providing a permanent remedy. The dealer recently confirmed the fault was present and advised that additional diagnosis and consultation with Honda technical support would be required to determine the cause.

The contact's daughter owns a 2020 Honda Odyssey. The contact stated that while his daughter was driving at an undisclosed speed, several unknown warning lights illuminated. The contact attempted to inspect the vehicle but could not determine the cause of the failure. The vehicle was taken to a dealer, where the contact was informed by the technician that the failure might be from the wiring connected to the rearview camera. The contact declined to pay for a diagnostic test. The contact attempted to repair and realign the rearview camera; however, the part needed to realign the camera could not be purchased and could only be serviced at a Honda dealer. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.

Upon starting the vehicle, it failed to engage in reverse. Although the backup camera activated, the vehicle remained stationary. After multiple ignition cycles, the vehicle eventually engaged in reverse and then moved forward in Drive. However, shortly after, the vehicle experienced a sudden loss of power and entered "limp mode," restricting speed to approximately 15–20 mph regardless of throttle input. The engine revved excessively high without corresponding acceleration, and a severe burning/heat smell emanated from the transmission/engine compartment. This failure occurred without any prior warning; notably, no dashboard warning lights or "Check Engine" indicators illuminated to alert the driver of a mechanical or electronic fault. The sudden, un-signaled drop in speed on a public roadway created a significant safety hazard for following traffic and risked a rear-end collision. The vehicle was towed to a certified Honda dealership where the Transmission Control Module (TCM) was diagnosed as failed. The TCM is currently being replaced under the Honda Certified Pre-Owned (CPO) warranty. We do not know what else requires replacement and repairs. The dealership will not cover the replacement of the transmission fluid, or engine fluid, despite the fluid being subjected to extreme heat and potential damage during the failure and subsequent limp mode.

This is now the second time that we are having a rear hatch failure. with about 37,000 miles on this van, the control module shorted out due to water getting into it due to a bad seam (according to other Odyssey owners who are suing Honda for this). We could not get the hatch to open or close, so I paid the dealer to fix it. Honda did give us a check after the fact to cover some of the bill. Now, with less than 51,000 miles, it has happened again. The hatch will not open or close. In the event of an emergency, this is a major safety issue, to be potentially stuck inside the cabin. The hatch started going up and down randomly, and we could not control it. Now, it won't go up or down. This van is is a mess. Not only does it have this issues, but the rear back up camera still does not work, even though it was recalled...they would not honor their recall, and the brakes occasionally come on without cause, when going around a corner and there is oncoming traffic. It thinks that we are headed for a collision, and it's another safety problem here in the northeast. Honda needs to own up to their quality problems relative to these three safety issues.

FEDERAL SAFETY RECALL 23V‑431 FAILED AFTER FOUR REPAIR ATTEMPTS - MULTIPLE SAFETY SYSTEMS NOW NON-FUNCTIONAL My Honda was subject to Federal Safety Recall 23V‑431 (MOST Communication Cable causing backup camera failure). After FOUR repair attempts, the original defect persists AND multiple additional safety-critical systems are now failing. REPAIR HISTORY: August 7, 2023 (30,749 miles) - Honda San Carlos performed recall repair 23V‑431. Dealer claimed issue resolved. October 5, 2024 - Original backup camera/infotainment failure returned. I documented with photo evidence but problem was intermittent. September 29, 2025 (48,038 miles) - Returned to Honda San Carlos. Same backup camera failure. Dealer attempted repair. November 18, 2025 (48,928 miles) - Returned to Honda San Carlos. Problem persists. Dealer claimed repair complete. December 20, 2025 - Returned to Honda San Carlos. Original problem PLUS multiple NEW safety system failures now appearing: Backup camera (original recall issue) - STILL FAILING Adaptive Cruise Control - ERROR Collision Mitigation System - ERROR Lane Keep Assist System - ERROR Auto High Beam System - ERROR Front camera - ERROR DEALER RESPONSE: Honda San Carlos now claims new failures are "unrelated" to recall 23V‑431 and proposes $2,900 for front camera replacement. I declined as all failing systems communicate via the MOST network that was subject to the original recall. SAFETY CONCERN: I now have a vehicle with MULTIPLE non-functional federally-mandated and safety-critical systems due to what appears to be the same MOST communication defect that recall 23V‑431 was supposed to fix. The recall remedy has demonstrably failed and the problem is worsening. Honda's recall remedy is inadequate and has resulted in cascading safety system failures. Vehicle is unsafe to operate with non-functional collision mitigation, lane keep assist, and camera systems.

Complete infotainment system loss and screen blackouts Repeated “Network connection lost” errors Inoperative reverse camera and parking assist systems Ongoing 12V battery drainage due to system faults My Honda dealer has diagnosed the problem as a defective floor wire harness and advised that the entire harness kit must be replaced at an estimated cost of approximately $7,000. While I greatly appreciate the 80% goodwill coverage already offered, the remaining $1,400 out-of-pocket expense is still a significant hardship — particularly since this is a known and documented defect affecting vehicle safety systems. This issue directly impacts the federally mandated rear visibility system (FMVSS 111), rendering the reverse camera and related safety functions inoperative. As such, this is not simply a convenience or infotainment problem, but a critical safety concern. Honda is charging $7000 to fix it and now it says it’s the floor harness kit. They are only covering 80%. I’m required to pay 1400 even though this is a known problem with this vehicle and it’s been occurring since I have owned the vehicle due to multiple visits to the dealership for a resolution, thousands of dollars being spent trying to figure out what it was, we already replaced the head unit and Head unit harness, multiple sensors on the doors, which were not even necessary because the battery was draining from the head unit and now I have no camera and my car is crashing and shutting off and Honda is refusing to escalate

The Infotainment system continually goes blank, while driving leaving the backup camera disabled and without navigation. I returned the van a week after purchase and did not get it back for a month. Despite the recall was never completed. It has been back to the dealer 6 times for the same issue with no improvement. Currently the problem still exist and the dealer WILL NOT HONOR the uncompleted RECALL ISSUE. The dealer insists the recall was completed yet the original issue was never resolved and is saying I will need to cover all costs.
