2020 Honda Odyssey

​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.

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 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.

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.

The rear coil spring snapped with no warning. My safety was at risk because the spring broke and collapsed on the suspension while driving on a tollway. The bottom of the spring that was snapped off completely which presents a safety risk to others as it becomes a heavy sharp steel projectile flying into traffic. The problem has been confirmed by a service center and it is a large issue as the parts are extremely hard to source due to the frequency of these coil springs breaking in Honda Odysseys. They can’t make them fast enough to replace. They are not supposed to break and are not part of any scheduled maintenance. The component has been inspected by a Honda service center. There were no warning lamps or symptoms. The part broke suddenly and without warning.

-Left rear spring broke from normal use. -safety: dealership said van was unsafe to drive -part is on backorder from Honda with no estimated production date. In order to get van repaired a used spring out of a junked Odyssey was installed
