2023 Honda Odyssey

I am submitting a formal safety complaint regarding a failure of the power tailgate system on my 2023 Honda Odyssey. The issue involves water intrusion into the liftgate control system, which has resulted in corrosion and subsequent failure of the power tailgate. This malfunction presents both a safety concern and a significant reliability issue, particularly for a vehicle of this age and mileage. What is most concerning is that this does not appear to be an isolated incident. There is a documented history of similar failures in Honda Odyssey vehicles, including prior class action litigation related to tailgate and electrical system defects. Despite this, the issue does not appear to have been adequately addressed or corrected in newer models, including the 2023 version. My vehicle has approximately 30,500 miles and is only slightly outside of the warranty period. I was explicitly assured at the time of purchase that the vehicle was reliable and that the manufacturer would stand behind it. However, I have since been informed that this repair will not be covered, despite the apparent design flaw and known history of the issue. A power tailgate failure is not merely an inconvenience—it can pose safety risks, especially when transporting passengers, children, or cargo. A malfunctioning liftgate can fail to open or close properly, potentially causing injury or limiting access in urgent situations. I respectfully request that NHTSA investigate this matter further, as it appears to be part of a broader pattern affecting Honda Odyssey vehicles. Consumers should not be responsible for costly repairs stemming from known defects that have not been properly resolved. Thank you for your time and attention to this matter. I am happy to provide any additional documentation or details if needed. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The power tailgate control unit (part #74970-THR-A12) failed on my 2023 Honda Odyssey at approximately 46,000 miles and 3 years of age. The tailgate stopped functioning entirely. Upon removing the interior rear trim panels to diagnose, I discovered the failure was caused by water intrusion into the rear body of the vehicle. Behind the interior panels I found: significant rust on interior sheet metal, green corrosion coating the power tailgate control unit, dried water stains showing pooled standing water that had evaporated over time, and clear evidence of repeated slow water exposure over an extended period — not a single incident. The vehicle has no rear windows that open and no exterior damage that would explain the water source. The symptoms and damage pattern match the class action Dubrosky v. American Honda Motor Co., [XXX] , which alleges defective polyurethane rear body seam sealant in 2018-2021 Honda Odysseys allowing water to leak into the rear driver's side panel and destroy the power tailgate control module. My 2023 exhibits identical symptoms, raising the question whether the same defect extends to later model years. SAFETY RISK: The class action documents that this defect has caused tailgates to open or close unexpectedly while the vehicle is in motion, fail to latch, short-circuit, and in some cases cause fires. Items in the cargo area can fall out during driving, creating road hazards for other vehicles. My tailgate failed completely; I consider myself fortunate it failed closed rather than opening in motion. The damaged components are available for inspection. The vehicle has been inspected and photographed by Pohanka Honda of Salisbury, MD, who confirmed the damage but denied warranty coverage. No independent inspection has occurred. WARNINGS PRIOR TO FAILURE: None. No dashboard warning lamps, messages, or symptoms appeared before the tailgate stopped functioning.

Back up camera display went black and issued error. This error is sporadic. please approve replacement.

Rear lift gate randomly opens and closes automatically while driving and when parked. My kids were in the back seat and there were groceries in the trunk that could have fallen out. Dealership said it's not a recall, and that it is due to a bad weather stripping around the rear window allowing water into the lift gate and damage the controls.

While driving, the vehicle loses power, hesitates, and jerks, then stalls and shuts off without warning, especially in extreme heat and stop-and-go traffic. The failure occurs more frequently when the fuel level drops below approximately half a tank. After stalling, the vehicle will not restart until it cools down for 20–30 minutes, then temporarily operates normally before the issue repeats. Warning symptoms prior to failure include loss of acceleration, hesitation, and engine overheating. A fuel pump–related fault code has been detected. The vehicle has stalled while driving, creating a serious safety risk due to sudden loss of power in traffic. This condition matches NHTSA Recall 23V858000, which states the fuel pump may fail and cause engine stall while driving. The fuel system component believed to be involved is available for inspection upon request. The issue has occurred multiple times and is reproducible under similar conditions.

I reported issues regarding egress failure and children stuck within the back seat of the van, Electronic Dashboard failing while driving, and no start issues amongst others (11709419). Previously the certified dealer stated the issues just could not be reproduced, despite my videos, however, today they stated a Honda admin level director showed and told them the issues are being reported by others, they dont know how to fix it, and I need to come get my car, continue driving it.

My 2023 Honda Odyssey Elite has recurring, intermittent safety-related malfunctions across multiple systems. The most serious issues are: (1) door lock/unlock and rear door opening failures preventing emergency egress (children trapped), (2) intermittent “no-start/no-response” where push-button start does nothing (no click/no crank and sometimes no lights/electrical response), and (3) intermittent dashboard/instrument/electrical abnormalities while driving. I also previously experienced dangerous driver-assist behavior including unintended automatic braking and lane/steering behavior in construction zones. Door/egress: Rear doors sometimes will not open from inside or outside even when the vehicle audibly indicates it unlocked. I have video of my children unable to exit the back seat. This is an emergency egress hazard. No-start/no-response: Multiple events where the vehicle appears electrically dead and will not start, then after waiting ~10–30 minutes it starts without a jump. Stranding hazard. Recent examples: 12/31/2025 – doors would not open initially; after entry, no lights/electrical and start button produced zero response; after ~10–20 minutes it started. 01/05/2026 – while driving, dashboard/instrument display went off; buzzing noise believed HVAC related occurred. 01/05/2026 – after parking at Costco, vehicle again would not start (zero response); after ~30 minutes it started. 01/06/2026 – locking/unlocking malfunction again; rear doors would not open despite audible unlock (video). Repair history: Authorized Honda dealer (Bell Road Honda) previously stated “cannot reproduce,” replaced DVD/recall items and performed a “reset,” but did not diagnose root cause; problems returned worse. Honda Customer Service case opened. Injuries: Prior unintended automatic braking event (reported around 08/29/2023) caused injury (my legs hit dash; child had marks from car seat) and near rear-end collisions. Request: Investigate potential safety defects

The front right sensor goes off randomly. Sometimes all day long for days, then nothing for a week or 2 then back to it. Various lengths of time, usually stressfully long times, with nothing aroundcausing stress and making fucus hard. It started a few months after getting the van. We cleaned it, had the dealer inspect it and no one has ever figured out why we have to live with this blaring warning alarm. The dash says object warning with it and if i close that out nothing stops the alarm but putting it in park which I can't do on the interstate or in pickup line at school

I have a 2023 Honda Odyssey. The engine is making a knocking noise. The oil has just been changed with 5.7 quarts, following the factory specifications, but the knocking is still there. The timing belt tensioner has also been replaced, as well as the high-pressure fuel pump. However, the knocking noise is still present, especially at low speeds.

The vehicle engine failed to restart after being idle for a few minutes in heavy traffic on Southern State Parkway. The vehicle’s Auto idle stop function was being utilized during this time.

I was driving about 15 mph in my neighborhood when my passenger side mirror exploded and flew onto my passenger side door/window. It hit so hard that it left a scratch on the window and on the paint.

The contact owns a 2023 Honda Odyssey. The contact stated that while driving approximately 30 MPH, the vehicle started to lose motive power. The contact stated that the check engine and several other unknown warning lights were illuminated. There was an abnormal metallic grinding sound coming from the engine compartment before the vehicle stalled. The contact was unable to restart the vehicle. The contact stated that a tow truck was called, but the driver was unable to restart the vehicle to shift into neutral(N). A tow truck with a dolly was called, and the vehicle was towed to the dealer. The dealer diagnosed the vehicle and determined that the engine had failed and needed to be replaced. The contact wanted a second opinion and had the vehicle towed to another dealer, who also determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 71,000.

The contact owns a 2023 Honda Odyssey. The contact stated that while the vehicle was turned off, the contact pressed the tailgate release button on the tailgate, and the tailgate closed and struck the contact on the back. Medical attention was not needed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000.

I was driving down the road and all the sudden I hear a loud bang/shatter noise. I look over and see that my passenger side mirror is hanging down and shattered. Didn’t notice any impact or anything when it happened. The mechanism that works the mirror broke. No damage to the plastic casing or nothing.

Engine shut off in traffic after Auto Idle-Stop failed to restart. While stopped at a red light with Auto Idle-Stop active, the engine shut down normally. When I released the brake to proceed, all electrical power dropped—cluster went dark, accessories reset, and the engine did not crank. Vehicle coasted dead across the intersection and required a full key-cycle to restart, exposing my family and surrounding traffic to a collision risk. Component that malfunctioned Dealer diagnostic later the same day showed the 12-V battery-current sensor reporting an internal resistance spike from 3 mΩ (normal) to 25 mΩ (fault), which commands the powertrain ECU to inhibit Idle-Stop restart (“Idle-Stop Inhibit – Large battery internal R” flag). An AGM load test confirmed the battery itself is healthy (958 CCA). Reproducibility / confirmation The stall occurred twice on public roads. At the dealer, the fault could be reproduced in the data list: resistance value jumps whenever the negative-terminal sensor is jostled. Inspection status Vehicle was inspected by the franchised Honda dealer; screenshots of the diagnostic session and the Midtronics load-test slip are available on request. Manufacturer has NOT yet repaired the sensor; dealer demanded an unnecessary battery purchase first. Warning indicators No MIL or warning lamps illuminated before the stall. After the first stall, a brief “Auto Idle-Stop System Problem” message flashed but cleared on restart. Risk Loss of propulsion and power steering in the middle of an active intersection without warning. If this sensor defect is common, any similar 2022-24 Honda minivan/SUV with Auto Idle-Stop could stall in traffic. Component is still installed and available for inspection. Filed report with FTC (report #188697846).

Auto stop/start struggles to start at lights or stopped traffic, rough idles and has already killed 1 battery, replaced under warranty and I'm having to charge my new one already since my car struggles to cold start sometimes! Incredibly stressful having 5 kids and 1car I spent a fortune on so it would last forever and it's a lemon I'm holding my breath doesn't strand us any time I have to break.
