2023 Honda Odyssey problems

UNKNOWN OR OTHER

After stopping the car in a left turn lane in the intersection, the car engine, dash board and infotainment system shut down. No warnings or other items appeared, the car died. After scrambling since it put traffic to a standstill, I shifter to park and returned on the car. Which worked and allowed me to continue. This happened again 1 week later while at a red light.

Seems like due to the auto idle, it makes the engine idle so low that it dies- my car died in middle of the road- the first time, I had it jumped, and mechanic said it was a fluke, second time, despite the testing not showing any issue, he said we can try to replace the battery, so we did, but 6 weeks later my car died, and it took 5 attempts to get it to restart with the external battery pack! each time there was NO issue with the electrical system- my A/C was running fine, the whole dashboard showed up fine. Seems like according to a class action suit in california this is an issue Honda KNEW about! People now know to press the Auto-off button so the car does not auto idle- but this needs to be done EACH time, or you will end up KILLING your engine! How is this allowed to be sold?? I was stuck in MIDDLE of a busy street with my DAUGHTER in the car!!!!

My 2023 Honda Odyssey (only 2.5 years old with 60,000 miles) recently had a complete tailgate failure. The dealership diagnosed the issue as a failed roof seal. This factory seal failure allowed water to leak inside the vehicle, directly shorting out the tailgate motor module causing the module to get very hot which could have caused a fire.The repair bill is $1,200. I contacted Corporate Honda to request Goodwill Assistance, considering the vehicle is so young and a roof seal should absolutely last longer than 2.5 years.Corporate Honda denied the assistance. They claimed a leaking roof seal is an "external factor" rather than a manufacturing defect. A vehicle's roof seal should protect the internal electronics from everyday weather. Labeling a structural seal failure as an external factor is an unacceptable excuse to avoid standing behind their product.

ELECTRICAL SYSTEM

When we are idling (at a red light), the engine will suddenly stop. We believe this is the feature of the start-stop system used to save gasoline. We will then have to completely restart the car as the car has been turned off. This creates a huge safety hazard at intersections. We have asked Honda about it twice now and currently replacing the starter. Our car is a little over 3 years ago with about 40k miles. The starter should not be failing at this point and we believe it is due to this start stop issue. The starter cost us $1400 in a car that is just over 3 years old with about 40k miles.

VISIBILITY/WIPER

The remedy for Safety Recall 23V-431 (MOST bus FAKRA connectors), performed 8/2023 at Joyce Koons Honda (Manassas, VA), has failed. The recall's stated safety risk, rearview camera failure when MOST communication is lost over 20 seconds, now occurs regularly on my vehicle. Symptoms began early 2025 and have worsened: intermittent loss of the rearview camera in reverse, infotainment reboots, and speaker popping (the warning signs listed in the Part 573 report). On [XXX] the infotainment system and backup camera were unavailable for over 50% of a long drive. Vehicle logs show 822 MOST network signal-loss events from [XXX] to [XXX] (avg ~15/week), predominantly "Tuner_Amplifier_Unit SUDDEN_SIGNAL_OFF" and "Meter SUDDEN_SIGNAL_OFF", the exact failure mode the recall remedy was meant to correct. I can provide the log data (chart and CSV). I reported the recurrence to the dealer on 5/31/2025; they said they could not reproduce it, and vehicle logs were cleared up to that date. I opened American Honda case #[XXX] in 10/2025 and escalated as case #[XXX] in 6/2026. On 7/1/2026 an American Honda representative told me Honda cannot authorize service without a dealer diagnosis and that I must pay out of pocket for diagnosis of this failed recall remedy, with reimbursement only as discretionary "goodwill." This appears inconsistent with 49 U.S.C. 30120, which requires recall remedies at no charge, including when the original remedy was inadequate. Honda revised Service Bulletin 23-046 to Version 3 on 12/18/2024, after my repair, revising parts and repair information, which suggests earlier repairs were performed with superseded parts or procedures. This is a rear-visibility (FMVSS 111) safety defect. Please record this as a failed recall remedy for 23V-431.

SEATS

The front seat slide lever on my 2023 Honda Odyssey failed completely on its own with no accident, force, or misuse involved. The lever detached from the seat rail mechanism, making it impossible to slide the seat forward or backward. The vehicle was purchased in August 2022 and this failure occurred approximately 3.5 years later, just 10 months outside the bumper-to-bumper warranty. When I brought the vehicle to the Honda dealer, I was informed I would be charged $100 for diagnostics even if I declined the repair, leaving me no real choice but to proceed. The total repair cost was $276 (parts $189.78, labor $70.95, misc $15.60) plus taxes. I contacted Honda Customer Relations requesting goodwill reimbursement. After a 3-week review, Honda denied the request. I believe this may be a manufacturing defect as another owner of the same Odyssey model has reported the identical failure.

FORWARD COLLISION AVOIDANCE: WARNINGS

Feb 2025 my windshield was cracked by a random fly ball at my grandson‘s baseball game. I contacted Safelite who put me in touch with South Florida Auto Glass out of [XXX] . They came down replaced the windshield reset the sensors. Everything was fine exactly one year later (2/2026) I got a warning on the dash that the radar was obstructed & all the sensors stopped working. I brought the car up to Largo Honda in [XXX] City and they reset the sensors. On my way home about half an hour into my 3 hr drive, the sensors stopped working again. I called the dealer (Largo Honda) but they have not returned my call. I love my car but would like to get this taken care of. Can you please let me know what I need to do. I will be staying in [XXX] from mid June until the end of July if something can be arranged during that time. Thank you!

STRUCTURE:BODY

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)

STRUCTURE:BODY

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.
