2020 Honda Odyssey Problems

Honda claims they fixed the recall for the MOST communication systems and the FAKRA cables. I have the vehicle and the connectors have not been changed. I called honda and they reefusing to fix the issue after I have priveded them with picture evidence and their repair manual.

The contact owns a 2020 Honda Odyssey. The contact stated that upon starting the vehicle in the driveway, the automatic braking system, adaptive cruise control, auto hi-beams, and Lane Keep Assist warning lights illuminated, followed by a beeping sound, and the systems became inoperable. In addition, the multi-point camera was inoperable. The vehicle was taken to the dealer, where an internal failure of the multi-point camera was diagnosed. The vehicle was repaired. The failure mileage was approximately 83,300.

Auto-stop/start function will randomly fail. Also appears to cause other electrical issues when starting up; complete loss of electrical power.

My 2020 Honda Odyssey EX-L intermittently fails to restart after the Auto Idle Stop feature shuts the engine off at a red light or stop. This has happened probably 10 times in the past 6 months. In order to start the engine, I must recognize that the engine isn't starting, turn off the vehicle, and turn it back on, often 2-3 times before it actually starts. This leaves the vehicle stopped in a traffic lane at an intersection with traffic trying to pass, which creates a risk of rear-end collision or cars trying to pass me. Cars have gotten into near misses trying to pass me while my vehicle is inoperable. I have no warning lamps or messages before it happens. History: The dealer performed Honda’s idle-stop software update (service bulletin 23-008) in November 2024 at about 63,100 miles. The problem continues. The battery was replaced in December 2022, and the dealer’s October 2026 inspection rated the battery “Good.” (as did a second independent auto shop). At 93,331 miles in October 2026 the dealer documented the complaint, charged a diagnosis fee, and recommended replacing the starter motor at a cost of $954.53 plus a diagnostic fee of $184.95. I contacted Honda, which opened a case and offered only partial goodwill coverage. I am not aware of any additional recall or warranty extension covering this on my model. This appears to be the same condition as NHTSA investigation EA25004 (no restart after auto start/stop engages), which covers 2018-2025 Odysseys. The failure persisting after the software update matches the investigation’s finding that complaints continue after Honda’s countermeasures. I can share vehicle inspection records if helpful.

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.

Auto-stop/start function will randomly fail. Also appears to cause other electrical issues when starting up; complete loss of electrical power.

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.

The power tailgate on my 2020 Honda Odyssey EX-L will not stay open sometimes. After it is raised it sags and soemtimes closes on its own, with a beep. This happened mutltiples times over the past year and a few times in XXX where it has closed on my young children while they were near or loading into the vehicle, and it hit me on the head. Nobody was seriously injured, but a heavy tailgate closing on a child's head or neck could cause serious harm. Honda service bulletin 22-018 (XXX) describes this condition and says to replace the right tailgate spring (74981-THR-A01) and clips. Honda has not issued a recall. I opened Honda Customer Care case XXX. The dealer told me Honda needs a paid $250 diagnosis before it will consider goodwill, which I declined. I am concerned this is a safety defect affecting other Odysseys and ask NHTSA to review it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

Front camera malfunctioning causing errors ACC, LKAS, Collision mitigation problem, road departure problem, auto high beam problem

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.

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.

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.

The contact owns a 2020 Honda Odyssey. The contact stated that while coming to a stop, the vehicle independently shifted into Park (P). The contact stated that the check engine warning light initially illuminated before the vehicle automatically shifted into Park (P); however, the failure escalated, with the vehicle shifting into Park (P) and shutting off the engine entirely without warning light illumination. The vehicle was able to be restarted following the failure. Additionally, the collision warning light illuminated on the instrument panel, with no vehicles nearby. The vehicle was taken to a dealer. The failure mileage was 55,000.

At roughly 5,000 miles, this 2020 Honda Odyssey was brought into an authorized Honda dealership due to transmission concerns. The dealership service department improperly evaluated the 10 speed transmission, and diagnosed a 9 speed transmission system, assured me that what I was feeling was completely normal, and instructed me to only bring the vehicle back if the issue got worse. At approximately 60,000 miles, after experiencing a transmission slip, I immediately took the vehicle to an ASE Blue Seal Certified shop for a complete transmission service to ensure proper maintenance was performed by qualified technicians. At approximately 80,000 miles, while driving on a highway during a family trip, the transmission suffered a sudden, catastrophic failure, resulting in a total loss of motive power at speed. Losing all propulsion on a high-speed highway created a severe safety hazard for my family and surrounding traffic. The complete mechanical failure was subsequently confirmed by a service center, and the failed transmission assembly remains available for inspection upon request. Initial symptoms were presented directly to an authorized Honda dealer in Annapolis MD while under factory warranty and the vehicle was properly maintained by certified technicians thereafter, but the underlying defect went unaddressed until complete failure occurred on the road.

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. NHTSA 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.

Dealership has not resolved the problem since they are waiting for parts

The rear coil springs on my vehicle failed before reaching 100000 miles. This affected the performance of the suspension system which reduced steering response and stability at highway speeds. It also likely caused early failure of the rear shocks which had to be replaced at about 105000 miles. The problem also lead to uneven tire wear increasing the risk of a tire blowout. The springs are currently being replaced with Honda OEM parts at a mechanic shop.

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.

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.

2020 Honda Odyssey EX-L, 49k miles, no prior collisions. 1. Faulty system: SRS airbag module, defective factory aluminum clip (official Honda recall defect). EDR data verified this component failure by dealer technicians. ​ 2. Safety risk: Driver airbag spontaneously deployed at 41MPH with zero impact. Seven occupants suffered soft tissue injuries and PTSD; sudden deployment created severe risk of secondary crash. ​ 3. Dealer confirmation: Bay Ridge Honda (Brooklyn NY) diagnosed and confirmed the airbag clip defect via EDR readout and physical teardown, filed service records for this issue. ​ 4. Inspectors reviewed vehicle: Honda dealer techs, EDR forensic specialists, and GEICO adjuster all inspected the car and confirmed no pre-crash damage. ​ 5. Pre-fault warnings: No SRS warning lights, error codes or abnormal electrical symptoms appeared before the airbag deployed unexpectedly.

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.

While traveling from Florida to our home in Pennsylvania in December 2022, we were on [XXX] and after going over a pothole, the side curtain airbag, and the driver seat side airbag inadvertently deployed. It was very traumatic and we are fortunate that we were able to pull off the side of the highway without getting hit by vehicles., The repair, which totaled over$16,000 was done by GERBER COLLISION AND GLASS Easton, PA. we personally are trying to recoup our out of pocket expenses of $781.08 from HONDA. And now, a month ago, May 2026,(almost 4 years after our incident) we received a SAFETY RECALL notification from explaining the exact issue we had.NHTSA Recall number26V227. we can provide photos and documentation, invoices, out of pocket expenses, etc if necessary but we have no idea how to include them on this form.

There where not other vehicals on the road.Rolled the vehical 3 times. On several occasions our honda van has slammed on the brakes without any vehicle or obstacle present.

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.
