2019 Honda Odyssey Electrical System Problems

The monocular camera in the windshield failed and multiple warnings are present. It has been well known by multiple consumers the camera fails more often in the 2018 - 2020 Honda Odyssey.

Issue: Intermittent infotainment failure – MOST network connection lost I am reporting a recurring electrical failure involving the infotainment system in my 2019 Honda Odyssey. The system intermittently loses all audio and displays a “MOST network connection lost” message. At times, the screen also goes black and reboots. This issue has occurred repeatedly over time, especially after extended driving (e.g., long trips). The audio will stop working completely, and the system may or may not recover after restarting the vehicle. Multiple repair attempts have been made, including replacement rear entertainment system. Despite these repairs, the issue continues to occur. Based on the error message and symptoms, this appears to be a failure within the MOST communication network, potentially involving the amplifier or related components. This creates a significant distraction while driving, as the system becomes nonfunctional and unpredictable. I am unable to access hands free phone capability and navigation features. I am also unable to access the heating and cooling features in the car when the screen is black. This has been happening since about one week after I purchased the vehicle in 2021. I am concerned that this may represent a broader defect affecting multiple vehicles.

On April 13, 2026, I brought my 2019 Honda Odyssey to a Honda dealership in Chicago, IL for a dealer-initiated recall service. The dealer contacted me and asked me to come in. Before the recall service, the vehicle had zero warning lights, zero error codes, and was operating completely normally. Immediately after the recall service was completed, the following warning lights appeared on the dashboard: Brake System warning, Hill Start Assist Problem, VSA (Vehicle Stability Assist) warning, and additional stability/steering system warnings. None of these warnings existed before the service. I returned to the dealership the same day. The service team cleared all error codes. However, within minutes of driving off the lot, all warning lights reappeared. This confirms the issue is persistent and not a one-time post-update self-check. I returned a second time. The service manager stated the warnings were not caused by the recall service and refused to investigate further. The dealer quoted 800 for diagnostic work. I also contacted American Honda by phone and was told they could not intervene. With the Brake System and VSA warnings active, the anti-lock braking system and vehicle stability control may not be functioning properly. This puts me and other drivers at risk, especially in emergency braking situations and on slippery roads. This pattern of multiple safety warnings appearing immediately after recall service on 2019 Honda Odysseys has been reported by other owners. The vehicle and its warning lights are available for inspection upon request.

I was driving to work on April 7th, 2026 and parked the vehicle at my company parking lot. Prior to parking, I noticed unusual smell and then parked the vehicle. I parked the vehicle around 8.10 am and I got the call from my facilities manager around 8.30-8.40 am that my car caught on fire and by that time I noticed Houston Fire Department extinguishing the fire. There were no check engine sign and this vehicle is a brand new vehicle when I purchased. Though there is no recall associated with my VIN #, the fire issue is similar to recalls for 2019 Honda Odysey. The recall numbers are 23V-751( Engine Fire Recall) & 20V-066 ( Electrical Wiring fire Recall)

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated and remained illuminated. The dealer was notified of the failure, but the vehicle was not repaired. The manufacturer was not notified of the failure. The contact believed that the failure was related to a sensor malfunction within the rearview camera. The approximate failure mileage was 114,000.

Both power sliding doors are malfunctioning, with the left side being critical. The dashboard intermittently flashes "Door Open" and "Left Sliding Door Problem" warnings during travel, regardless of speed or road conditions (highway, low-speed, and cornering). A certified Honda technician (Case #16203079) confirmed DTC B2037 is stored for the left sliding door ratchet switch. The diagnostic report explicitly states the rear latch is failed/stuck in the open position, resulting in a half-latched state that "CAN OPEN WHILE DRIVING." The right door also shows intermittent issues with the ratchet switch and pinch sensor. Despite this documented, life-threatening safety defect, American Honda has refused repair assistance. I have video evidence of the warnings flashing while in motion.

Multiple safety systems on my 2019 Honda Odyssey Elite have simultaneously failed, including LKAS, ACC, Collision Mitigation Braking System, Auto High-Beam Headlights, and other driver-assist features. The dashboard displays warnings for nearly every safety-related system, and the vehicle disables these features without warning. **Detailed Description of the Problem:** Whenever I start my vehicle, multiple error messages are displayed related to the Lane Keeping Assist System (LKAS), Adaptive Cruise Control (ACC), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, Auto Headlights, and other safety features. These warnings appear together and persist even after restarting the vehicle. Apparently, this issue is widespread among 2018–2020 Honda Odyssey owners, with many reporting the same cluster of system failures. The problem appears to be related to a malfunction in the vehicle’s electrical system, sensors/ cameras, or control modules. In my case, the failures occur without any external damage, weather event, or driver action that would explain the sudden loss of safety functionality. When these systems fail, the vehicle disables critical safety features such as automatic emergency braking, lane keeping, adaptive cruise control, and automatic headlights. This creates a significant safety risk, especially at highway speeds or in low‑visibility conditions. **Frequency:** The issue occurs whenever the vehicle is started, affecting my driving everyday.

Five days after getting back our car from the Honda dealership where they “fixed” the two recalls all warning lights came on and not turn off. Steering, breaking, accelerating all are difficult. There were no issues prior to the dealership “fixing” the recalls. The car was just at our mechanic for brakes and they check our engine, fluids etc every time. There were no prior issues.

I was commuting home, about 30 minutes into the drive, all of the dashboard and radio went blank for a few seconds. It came back on and the break light, anit-collision, lane departure, lights were all flashing. It did this 2 more times in the over the next 5 minutes. I was concerned for my safety because I wasn't sure if my breaks and all the other things were working propoerly. I didn't know how fast I was going or if my car was going to stall on the highway. I see that a recall was issued by honda yesertday, not for my car model, but a similar issue (a software bug can cause the instrument panel and rear-view camera to go blank). It has not yet been inspected by a repair person. There wre not any warning lights prior to this happening.

I own a 2019 Honda Odyssey with approximately 100,000 miles. The power tailgate began malfunctioning suddenly. The rear hatch repeatedly unlatches and beeps as if it is opening even while the vehicle is in motion. After inspection, the dealership stated the tailgate control module failed due to water intrusion into the rear hatch area. I was told this is a known issue affecting multiple model years of Honda Odyssey vehicles (2018–2021), but there is currently no recall. This malfunction creates a potential safety hazard because the tailgate may unlatch unexpectedly while driving and causes continuous warning alarms and electrical issues. Owners are being required to pay for repairs caused by what appears to be a design defect allowing water to damage the tailgate module. I am requesting that this issue be investigated for a potential safety recall.

My infotainment system has gone completely black, resulting in the loss of several critical functions, including the rearview camera, AC vent direction controls, navigation, and radio. This has made reversing significantly more hazardous, and the lack of proper AC control is especially inconvenient during the summer. The Honda dealer performed a recall-related diagnostic, but it did not resolve the issue. After further inspection, they concluded that the infotainment unit has completely failed. However, they were unable to identify the root cause and recommended a full replacement at a cost of $2,850. I contacted Honda America to request assistance or a goodwill discount, but my request was declined. Due to the high cost, I have not proceeded with the repair. Although my vehicle is not currently on the recall list and has approximately 70,000 miles, there is a known history of infotainment system issues in Honda vehicles. A complete failure of this unit at this stage is unexpected and potentially related with their manufacture, as it is generally intended to last the lifetime of the vehicle. Thank you for your consideration

All the warning lights shows up in the dash and the problems are diferent like bad battery or front monocular camera and all the futures assistence stop working like automatic brake cruise control.. etc

The driver-side power sliding door latch, motor and cable system on my 2019 Honda Odyssey Elite failed. Honda performed Recall A88 (sliding door handle cable repair) in 2021. After this repair the door began intermittently failing to close fully and would close about 80% before the sensor triggered it to reopen. This continued until this week when the door suddenly stopped latching completely. The automatic door buttons no longer work and the door can only be moved manually. I believe my vehicle should also be included in recalls Z33 and O36 addressing sliding door latch failures affecting similar 2019 Odyssey vehicles. The failed components are available for inspection upon request. This defect creates a serious passenger safety hazard. Because the door will not latch, it opens while driving. The automatic function does not work and the door can be moved manually but will not latch. This creates risk of passenger ejection, especially children, and the possibility of the door opening during a crash. The vehicle is unsafe to operate. Yes. The failure was reproduced and confirmed by a Honda dealership that inspected and diagnosed the sliding door failure. The vehicle was inspected by a Honda dealership and I was charged a diagnostic fee. Honda refused recall or goodwill coverage because my VIN is not included. I request the repair be performed free under recalls Z33 and O36 and the diagnostic fee reimbursed. I am waiting for NHTSA inspection and request Honda be required to include my vehicle and repair it at no cost. Before total failure the door would close about 80% and automatically reopen. When it stopped working this week, the dashboard displayed a “Left Sliding Door Problem” warning and the vehicle produced continuous beeping while driving.

Multiple possibly related issues: 1) Power Lift gate (rear hatch) will on occasion close unexpectedly and can trap a person between the hatch and the back bumper of the car. Very dangerous for children and for handicap adults who cannot move quickly (I have had both have issues with mine). (Has consistently occurred since purchase, dealership refuses to acknowledge/correct issue when it was under warranty). 2) Random electrical problems (various sensors malfunctioning, sliding doors unable to open/close, power lift gate would not close/latch). Occurred twice (Jun 2023, Feb 2026).

Multiple system problems constantly on my dashboard. Has brand new spark plugs and battery and problem is still there.

As I was driving the car computer showed overheating, brake failure, transmission failure and the car started shaking and the engine died. I had the car towed by triple AAA to a auto repair shop, but the next day when they went to fix the problem could not replicate it.

The computer system for the sliding doors and back hatch do not work properly. They will occasionally stop working or will stop mid-open or close. In addition, on three separate occasions the sensors did not work. One time the back hatch started to close while I was getting something out of the trunk. It did not sense by body and would not stop. I tried to stop it physically but the hatch continued to close. If I had not gotten out of the way, it would have crushed me. This happened to my husband on a separate occasion as well. He is athletic - [XXX} and [XXX] and was pushing up with all of his strength and the hatch continued to close on him before he had to jump out of the way. On the third occasion - the sliding side door started to close on my [XXX] as I was helping him into his car seat. This issue WILL KILL SOMEONE. The 2019 Honda Odysseys need to be recalled immediately. I alerted my local Honda service center (Don Jacobs in Lexington, Ky). I asked them to notify Honda and they told me they wouldn't do that unless more people had similar issues. They have attempted to fix the computer system on several occasions and always say the issue is fixed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Odometer Fraud. The contact purchased a 2019 Honda Odyssey. The contact discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 54,970 and at the time of registration, it was discovered that the mileage was 254,970.

Since January 15, 2026, our Honda Odyssey has experienced a persistent and unresolved infotainment system failure affecting critical functions, including the rear-view camera. The issue has been reported across three separate service visits (January 15, March 6, and March 26, 2026), during which attempted repairs—including wiring adjustments, battery replacement, and amplifier replacement—failed to resolve the malfunction. Despite escalating to a regional Honda engineer and multiple dealership interventions, the system remains inoperable, and the defect continues to immediately reoccur after each repair attempt. As of April 12, 2026, the vehicle’s infotainment system and rear-view camera are completely non-functional. The issue has persisted for 87 days, resulting in loss of use of key vehicle functions and raising significant safety concerns due to the inoperability of the federally mandated rearview camera (FMVSS 111). The repeated unsuccessful repair attempts and extended delay have led to the conclusion that the vehicle is currently unsafe to operate and has not been restored to a usable condition within a reasonable timeframe.
