Honda Odyssey 2020 — Problemas reportados

Front Camera failure which disables the entire Honda sensing Suite, Shuts down Cruise control, lane keeping assist, front collision warning and Auto emergency braking. This has caused the loss of many safety features intended to prevent accidents and injury. There are numerous warning lights on the dash that are constantly displayed and can be a distraction to other safety or maintenance concerns. Dealer has diagnosed the problem to be an issue with a faulty front camera system. The repair for this is extremely expensive

While sitting at light, Idle stop engaged and engine stopped - then car lost all power. I was boxed in in heavy traffic and could not move. The car could not be shifted to neutral when I tried to consider how I could get off the road. After a minute or so power suddenly returned to the vehicle and I was able to proceed. The next day, lucklily at a less busy intersection the same issue occurred (again with Idle Stop engaged). After these events I scheduled to take to dealership. Over the next several days I made sure Idle stop was not engaged and had no further issues. Took to Honda dealership and they determined started needed to be replaced. This repair was completed at my expense.

Code: U3000-49 Multi purpose camera unit/millimeter wave radar internal electronic failure Camera

While Automatic IDLE was on, engine shut down at a red light. Dashboard showed message: put in park. Alternator was fine. Battery fine. I DID get the software update but this happened AGAIN. This time was able to put in park and was able to start the car. I have to remember to turn OFF Automatic IDLE to avoid this from happening again.

SUNROOF stopped working. diagnosis: motor is the issue. I may have used it 20 times since purchase. I believe water intrusion caused this. it just decided to stop working.

after a heavy rain, the automatic tailgate opening/closing function stopped working. Trunk can only be opened manually. warning message on dashboard: POWER TAILGATE PROBLEM. water intrusion. cracked seals.

Upon starting my Honda Odyssey, the dash immediately started saying, Collision Mitigation System Problem, Adaptive Cruise Control Problem, Road Departure Mitigation System Problem, Lane Keeping Assist Problem, Auto High Beam Problem.

The contact owns a 2020 Honda Odyssey. The contact stated that on several occasions while stopped at a red light, the vehicle shut off unintendedly and had to be manually restarted. The battery warning light was occasionally illuminated. The vehicle was taken to a dealer where it was diagnosed, and the contact was informed that the battery needed to be replaced. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was 39,000.

One morning, with no prior issues, we started driving our van and it suddenly displayed several warning lights, including brake system, adaptive cruise control, auto emergency braking, forward collision warning, lane departure warning, and lane keeping assistance. We took it to Darcars Honda in Bowie, MD who diagnosed it as a front facing camera failure. The dealer replaced the camera and kept the old one. This failure in a six year old van increased the danger of collision while operating the vehicle.

The auto idle start when I am at a red light it will turn off and put it in park. I have to restart the van and put it back in drive. I believe this to be a safety issue. I have my kids with me and its dangerous. I would like to know what can be done and why hasn't this been a recall. I have to remember to push the auto idle button each time I get in to drive otherwise Im afraid ill get stranded at an intersection. Its been going on for at least a year and the dealership thought it was the battery we have replaced the battery so that is not the issue.

Front windshield mounted sensor failure on 2020 Honda Odyssey. Disabled Honda Sensing safety suite which included lane keep assist, adaptative cruise control, auto high beams which all triggered warning messages on the dashboard which all occurred at the exact same time. This problem has been reproduced an inspected by Honda of Frontenac.

The power liftgate is no longer working and locked shut a few hours after multiple warning messages. There was heavy rain that night. It did randomly open and shut all or part of the way before that, sometimes after closing. This often happened after heavy rain when the van was not even in use. It could have popped open at any time, and then warning messages popped up and blocked the notifications and other dashboard information and distracted the driver. It was confirmed by the dealer and they recommended it get replaced, however, the electrical panel was corroded by water damage from a suspected leak in the roof rail. The dealer said that it would probably happen again and not to get it fixed until the leak was determined. Many others have reported this online regarding the Odyssey.

Both sliding door keep stopping when closing or opening. Have to manually do it sometime. Rear door don't close anymore either only opens has to always be manually close.

The monocular camera failed causing the car to lose all ADAS features. Honda said this not a recall issue and I have to pay for the repair which is significant. Not only are all the ADAS features lost, but the dashboard flashes warnings and beeps reflecting the lost features

Stopped at a light, auto idle stop engaged, engine shut off normally. The moment I pressed the gas, everything died — engine and all electronics. I pressed the start button two or three times with no response, then it finally started. It was still in Drive. The hazards wouldn't turn on right after, then everything gradually came back to normal.

The electronic module for rear power tailgate quit working due to water getting inside module. This causes rear lift door to malfunction. Ive seen online there's been a class action lawsuit for this and the door can open randomly. This has not happened to mine. It just quit working and beeps excessively. I had it repaired and it happened again 7 months later. It has been diagnosed by honda dealership. Thanks

U3000-49, multipurpose camera unit internal failure, no impact, no glass work

On September 14, 2026, my 2020 Honda Odyssey experienced a sudden, severe low-pressure fuel pump failure while idling/parked. The engine began running extremely rough, surging repeatedly between 300 RPM and 1,000 RPM, knocking, and stalling. I was parked at the time, preventing a severe accident. Upon trying to restart, the vehicle turned over multiple times and would only catch when depressing the accelerator pedal, accompanied by cylinder knocking and an engine thermal spike. The vehicle was towed to an independent repair facility (Tuffy Auto Service). The diagnostic scan confirmed DTC P0087 (Fuel Rail/System Pressure - Too Low). A mechanical gauge test showed the low-side fuel pressure dropped to 10 PSI (far below the standard operating pressure of 50–60 PSI). The shop verified that the in-tank low-pressure fuel pump assembly failed internally and requires complete replacement. This failure, symptom pattern, diagnostic code (P0087), and component match the exact defect profile in NHTSA Recall 23V-858 (Denso Low-Pressure Fuel Pump Impeller Failure). However, when checking my VIN, American Honda claims this specific vehicle is excluded from the recall range. American Honda Consumer Relations subsequently refused goodwill assistance due to non-dealer service history and vehicle resale status. This creates a severe safety hazard. A vehicle experiencing a sudden drop to 10 PSI fuel pressure while driving in traffic will lose motive power, stall unexpectedly, and disable power steering and braking assist. I am submitting this report because American Honda has failed to include all affected production batches in Recall 23V-858. I request NHTSA expand Recall 23V-858 to include out-of-range 2020 Honda Odyssey VINs exhibiting identical low-side fuel pump failures.

I randomly received a series of 6 warning messages when starting the car on 9/3/26. They were all warnings related to the automatic safety features such as lane departure, collision detection, auto bright lights, etc.I took it to the dealer on 9/4/26 & they diagnosed an internal failure with a multi-purpose camera embedded in the rearview mirror. The dealer ordered a new part, installed and reprogrammed and recalibrated the camera. This vehicle has been owned only by me, is kept in a garage away from weather exposure, there is no reason for this part to fail on a 6 year old car with a hefty cost to the consumer.

As per the attached there is a recall on this for the airbags and you are in charge of this On Sunday XXX I was driving in [XXX] and suddenly my air bags deployed. (all driver side airbags from front to back, not the steering wheel). I took the vehicle into a body shop they reached out to my insurance for a claim.

​I am writing to issue a formal complaint regarding gross negligence, logistics failures, and deceptive service practices surrounding mandatory recall work on my 2020 Honda Odyssey. ​1. Failure to Complete Recall Software Work After Overnight Retention On Tuesday, September 1, your service department texted stating: "the software update did not finish. We do need it overnight." We agreed to leave the vehicle. However, upon pickup, the infotainment display confirmed that the update was never completed and remains stuck at Step 5/6 (System Update 24084.7 / Front Control Box B.1.4.6). Retaining a customer's vehicle overnight under the guise of completing software work and returning it unfinished is a direct misrepresentation of labor performed. ​2. Extreme Logistics Failure and Disregard for Customer Time At 12:55 PM on Wednesday, September 2, your department texted: "Ready to go now!" My wife arrived promptly, yet your staff forced her to wait until 2:40 PM—nearly two hours later—before physically releasing the car. This gross delay caused her to miss our children’s school pickup, forcing me to leave my workplace unexpectedly to handle child transportation due to your operational incompetence. ​3. Cascading Network Faults and Critical Safety Systems Disabled Prior to service, the dashboard displayed minor Sensing suite warnings, for which your department quoted an exorbitant $250 diagnostic fee. Upon picking up the vehicle, the dashboard warning count escalated from 5 to approximately 9 active system failures. Due to the interrupted ECU software installation corrupting the CAN-BUS network, the following primary vehicle controls are now completely inoperable: ​Supplemental Restraint System (SRS / Airbag) (Newly triggered post-service) ​Vehicle Stability Assist (VSA) System ​Automatic Brake Hold System ​Electric Parking Brake (EPB) System ​Electric Power Steering (EPS) ​Hill Start Assist ​Honda Sensing Suite (Lane Departure, Collision Mitigation, Road Departure) ​Releas

Safety mitigation compoments failure that started as intermitent issues and now is consistent. Warning lights come on for Adaptive cruise control failure, Forward collision failure, Lane departure warning failure, high beam failure, lane keep assist failure and others all link back to the DTC U3000-49 internal multipurpose camera unit failure. This compenet failure puts all oppcpants and other vehicles at risk as driver have become reliant on all feature working properly to enhance safety for all. The problem has been diagnose and inspected by two different dealerships. No accident or vehicle comprimised, the camera component just fails and have talked to two other familes that have had same issue. The issues started as a inteitent flsh of all the warning lights and that moved to a constant issue. Currently you can drive the vehicle for a various amount of time and eventually the lights will go on or the dash will be lit up like a christmas tree as soon as you turn it on. Concerned as this is a vehicle that a majority of Moms and kids drive in, as is the case for our familiy.

The contact owns a 2020 Honda Odyssey. The contact stated that while driving approximately 60 MPH, the rear hatch tailgate door opened unintendedly. The vehicle was previously taken to the local mechanic who diagnosed the vehicle with electronic tailgate door control module failure, which was caused by water intrusion from the roof drainage system. The control module was replaced but the failure reoccurred on two other occasions, and the electronic tailgate door control module was replaced by the owner. The local dealer and manufacturer were notified of the failures, but no assistance was offered. The failure mileage was 50,000.

The contact owns a 2020 Honda Odyssey. The contact stated that the Traction Control, Adaptive Cruise Control, Lane Keeping Assist System, and Road Departure Mitigation warning lights illuminated. The vehicle was taken to a dealer, where the cause of the failure could not be determined. The contact continued to drive the vehicle as it passed state inspection. While driving approximately 65-70 MPH, the cruise control suddenly failed, requiring the contact to manually steer the vehicle. Additionally, the Collision Mitigation Braking System, battery, and ABS warning lights illuminated. The contact stated that the ABS light illuminated after the brake pads were recently replaced, and the ADAS calibration was not performed. The vehicle was taken back to a dealer, who informed the contact that the monocular camera burned out due to windshield brackets; however, the contact stated the failures occurred prior to the windshield replacement. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The contact owns a 2020 Honda Odyssey. The contact stated that five days after the vehicle was repaired under NHTSA Campaign Number: 26V332000 (Air Bags), while starting the vehicle, five warning lights were displayed. The Lane Assist warning light and the cruise control warning light was illuminated. The dealer was contacted, and the vehicle was diagnosed with a front-facing camera failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 55,000.

The multipurpose camera located behind the rear view mirror gets too hot and has errors and then fails and is expensive to repair. I had the recall completed for the camera at the rear of the vehicle and then the multipurpose camera in front died the next day.

2020 Odyssey Elite multipurpose camera unit internal electronic failure DTC U3000-49. Component is still installed and available for inspection upon request. Failure disabled Honda Sensing safety systems: Adaptive Cruise Control, Lane Keeping Assist, Lane Departure Warning, Forward Collision Warning, Collision Mitigation Braking, Road Departure Mitigation, Automatic Emergency Braking, and Auto High-Beam. Dash showed Honda Sensing system failure warnings. No crash, no injury. Vehicle remains drivable but without active safety features, increasing risk of crash, especially on highway. Dealer confirmed failure and reproduced it, recommended camera replacement plus ADAS static/dynamic calibration, quoted $2,243. No prior symptoms, no accident, no damage, well-maintained. First warnings appeared Aug 2026 and stayed on continuously. Manufacturer was notified and denied goodwill coverage, stated out of warranty. This is a known widespread defect — same U3000-49 failure documented in NHTSA complaints 11615376, 11584269, 11603801 for 2018-2020 Odyssey, Art's Automotive public statement on pattern, YouTube coverage 2016-2021, and eBay repair market with one seller showing 485 repairs for this exact camera and 111 watchers. Similar to prior Honda backup camera recall. Request NHTSA investigation / recall consideration.

multipurpose camera stopped working. no direct physical damage to camera so it shouldn't need replacement after 6 years. others with honda odyssey have reported similar defect.

when I start the car, I get 8 or so warnings: Adaptive cruise control, Automatic emergency braking, forward Collision warning, lane departure warning, lane keeping assistance, etc. the air bag warning for passenger also blinks. the dealer indicates this is a faulty front camera and will require about $2500 to fix it.

Multipurpose camera failed. Now I have no cruise control, auto high beam, lane keeping assist, collision mitigation, road departure mitigation.

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.

The engine auto idle system failed at a stoplight. The auto-idle engaged, but when I took my foot off the brake, the engine did not restart. It completely shut down, putting my car in park in a busy intersection. The engine light and an error message flashed briefly but disappeared. I was able to restart the car and drive, however, only after waving several other cars to pass by me. I've noticed recently the restart function lagging, and if I put my foot on the gas too soon, the car lurching and jerking forward (indicating the engine isn't restarting quickly or properly). I recently had a full routine service on the vehicle, indicating battery life is good. No other issues appeared such as overheating.

Error U3000-49 Multipurpose camera failure...Adaptive Cruise Control, Lane Assist, etc. do not function. I cannot even get a basic cruise control to function! Honda wants $2000+ to fix this problem that has become a common problem with 2020 Honda Odysseys. Please push for a recall!

Multipurpose camera internal failure disabling my all my safety features in ADAS.

Camera failed after 65,000 miles and is a known problem out there with thousands of these requiring a $2000 dealer replacement.

NHTSA Campaign 26V227000. My vehicle VIN: [XXX] Vehicle modified by Vantage Mobility International (VMI) into a Mobility Van. Van submitted to dealer 7/16/2026. Dealer claims they cannot perform work until factory clearance obtained. I cannot get information on when repair can be completed. VMI engineer Andrew Socha (602) 304 3294 informed me on 7/20/2026 there was nothing in the VMI modification that would interfere with this safety upgrade I called American Honda Motor Co, Inc Headquarters in Torrance, CA (800 999 1009) pn 7/22/2026 where safety recall department employee Antonio (would not give last name) commiserated with my situation but had no authority to ameliorate the situation I can't get a straight answer from American Honda Motor Co. Inc. and when or whether this repair is done. The 30 day window for this repair is closing in 5 days. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The driver side rear coil spring broke abruptly on both the top and bottom leaving the majority of the spring mechanically unattached. The driver side rear shock also broke from the additional strain on it. With a complete loss of suspension on the rear driver side, as I hit bumps on the freeway, I could feel the van jerking quickly nearly sending me out of the lane. If it was slippery with rain or snow, I felt like the van would spin out. The broken parts were confirmed and shown to me by an independent service center. The shop also informed me that he has seen many Honda Odysseys from the same model year with broken coil springs. When he called to order parts from the Honda dealer, none of the 3 nearby dealers had springs in stock and all had vans in their service center waiting to replace their broken springs. There were no warning signs before this happened. I perform all regular maintenance such as brakes, tire rotations/replacements, and oil changes by auto shops so the car is regularly looked at. This happened at 6 years old and 60,000 miles. While springs generally lose some tension, snapping through in two places is unacceptable. Honda has recalled other vehicles for rear suspension failures and needs to expand that recall to additional vehicles. Specifically the Odyssey.

My son turned around in his second-row seat of our Honda Odyssey, causing the seat belt to cinch tightly around his waist. Even after the buckle was released, the seat belt continued to tighten instead of loosening. It became so tight that he could barely breathe, and we ultimately had to cut the seat belt to free him. There was no way to manually release or loosen the belt once it had locked. This presents a serious safety hazard. Seat belts should include an emergency release or override mechanism that allows a locked belt to be loosened during an entrapment situation.
