2020 Honda Odyssey complaints

The Auto-Idle Engine system malfunctions constantly. For example, several times I almost got into dangerous or possibly fatal accidents- I was in stop and go traffic on an interstate. Traffic slowed to a stop. I held the brake. The engine idled. I took my foot off the break and moved it to the gas when the traffic abruptly restarted. The car stalled and shut down. The cars around me expected me to go and had to swerve around me while I desperately tried to restart. There is no way to set a default that the auto idle feature is off when I start the car. I have to remember to turn it off. This also happened at an on ramp with a stop light, I almost got rammed by the car behind me. This feature is a drain on the engine and battery and is dangerous when it is not working correctly. The default should be off or just not have it at all. Honda dealerships aren’t willing to help me.

The rear lift gate fails to hold in the up position, the powered lift gate subsequently and randomly closes on its own without any driver intervention. The powered lift gate closed on me while I was retrieving groceries, almost crushing me had I not forced it back up by force. This has happened multiple times and could be lethal to a child or even an adult. The vehicle only has 39,xxx miles and has been used lightly as a family vehicle. The vehicle is available for inspection by NHTSA officials. Additionally, I have seen other vehicles with the same problem video taped on YouTube. Such links can be provided to investigators. Honda should recall these vehicles and disable the automatic closing of the lift gate that is occurring without any driver intervention. It is beyond reasonable to assume this fault can be lethal or cause serious bodily injury.

The contact owns a 2020 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while attempting to move from a stop, the brake pedal was released, and the engine stalled. The vehicle was restarted, and the vehicle was driven to the destination. In addition, the contact stated that on several occasions, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact stated that the vehicle hesitated. The contact stated that the collision detection system warning light was illuminated. The vehicle was taken to the dealer however, the vehicle was not diagnosed. The contact was requested to provide a diagnostic fee. The dealer was made aware of the failure but confirmed that parts were not yet available. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 35,000. Parts distribution disconnect.

The contact owns a 2020 Honda Odyssey. The contact stated that upon starting the vehicle, the instrument panel failed to display any information and the rear-view camera failed to display an image. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the gauge control unit. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 20V439000 (Back Over Prevention, Electrical System), but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was unknown.

Three times now our 2020 Honda Odyssey's entire instrument and infotainment system has gone out - both screens at the same time just don't turn on. Which means we have no MPH gauge or back up camera. It is extremely unsafe to drive without a speedometer and we paid extra to get a van with a backup camera and now we don't even have that. We've taken it to Honda and are getting charged to replace the entire system, even though it is clearly a connection issue (since it turns back on by itself). On the exact same vehicle, the entire right rear shock is completely blown out and needs replaced. Both happened with no warning. Honda is not helping on a vehicle that only has 40,000 miles on it.

The rear hatch door closed with me standing under it and I injured my arm trying to stop the door from closing on me. The door will not stop closing even with a person there. This is very dangerous! The mechanic said that we need to replace the rear struts- this car is only 3 years old!

The design defect of the camera in front of the car seriously affects the life safety of the driver. The dealer did not pay attention to this problem. The car did not collide, but six error prompts appeared during driving: Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Auto High-Beam Problem.

Our vehicle is only a few years old and the front camera failed. It will not do any Automatic Emergency Braking, Forward Collision Warning, etc. Honda refuses to cover this even though it is a manufacturer defect.

Power tailgate module exposed to water due to manufacturer defect in sealing above module. causing various electrical systems to fail including safety features. I do have the damaged module. Tailgate opened and wouldn’t close, when car in motion. Unable to use vehicle, the amount of electric items, due to fear brakes or transmission would fail while driving minivan full of young children Vehicle had warning light shortly after heavy rain. Was intermittent.

Auto idle stop. When the auto idle stop is on, when the vehicle is stopped at a light or due to traffic the vehicle while in drive will completely turn off. Unable to hit the accelerator to move as designed. We have to restart the vehicle and sometimes it takes multiple restarts. Extremely unsafe since we are unable to keep up with traffic. It has happened multiple times without warning. We have to make sure make a point to keep the auto idle engine turned off, but when you turn the car on it is automatically turned on. Called Honda, no recalls on this issue.

At random the following would come on when driving or when starting the vehicle up. It would also reset itself at random. Very scary when you have small children in the van. 1.Collision Mitigation Braking System (CMBS) 2.Road Departure Mitigation System (RDM) 3.Lane Keeping Assist System (LKAS) 4.Adaptive Cruise Control (ACC) 5. Auto head lights The vehicle has not been in any collision. This started after a required update was installed. The code reader scan code does not match what is being stated. When you are using the cruise control then it would turn off. Brake warning will not work. The cable harness for the audio for the entire van was redone last Summer 2023

We bought a used 2020 Honda Odyssey, and a few months after buying this vehicle, the infotainment screen blanked out and the vehicle information screen also blinked out. This occurred at the same time with no warning whatsoever. I just turned on the car, and none of the screens came on. These screens are the ones that show the mph, our mileage, cruise control, etc, and also the screen that shows the back up camera, in car calling, back up alert system. None of that works anymore. We made an appointment to take it to a Honda dealership and a few days later it flickered back on and so we did not keep the appointment. Just a month and a half later, it happened again and this time it has not come back on for over a month. We took it to the dealership and were charged $200 for them to tell us it was something wrong with the Honda computer system and the whole thing would need replaced and we would be charged $1800. This is on a barely 4-year-old vehicle & we did not have the money to replace a defective system. So we have been driving without a mph display. We put our phones up on the dashboard and try a GPS MPH app, but it is wildly inaccurate, and it is a major safety concern because we have no idea what speed we’re going and we have to guess. This is a car with low mileage and barely 4 years old!! We paid a lot of money for the back up camera, in car calling, and extra features like that specifically for the safety of those features. And now we’re being told that basically they

Adaptive cryise control, collision mitigation system, road departure mitigation system, lane keeping assist, auto high beam all have errors and are not working. It happened without cause. Apparently it isn't uncommon for radar and sensor safety systems to just fail for no reason. The dealer said it could take several days to figure out the cause then a lot of money to fix it. The safety systems should not fail for no reason.

When trying to close Rear sliding doors it just beeps once it gets half way closed then it gos back open and it won’t close unless you turn off automatic mode to manual and you have to physically Very hard to close them and they are very hard to open like very hard to open and close so if you don’t have the strength and it happens to you your screwed or stranded with your little kids and specially if you don’t live in a great neighborhood that can be very scary and from what I’ve researched online that on the Honda odyssey it is a very common issue and Honda just wants you to spend 1500$ to fix it and from what I’ve seen it’s either the cable or the motor or the rollers apparently it’s very common for the motor and the cables to die and break and if you call the Honda dealer, they know exactly what the issue is that’s how common it is. I definitely believe it should be recall. And I believe in my opinion, that’s a major safety issue

1. Issue: *Multiple (5+) warning lights on dash [i.e. road departure mitigation system problem, adaptive cruise control problem, lane keeping assist problem, auto high beam warning, collision mitigation system problem etc.] 2. Honda Dealer diagnosed & confirmed the issue as "multi purpose internal camera failure" 3. A failed camera affects safety related functionality which affects the safety of both driver and other drivers. 4. The issue first appeared March 16th, 2024

Multipurpose front camera failure causing adaptive cruise, lane keep, auto highbeams, and collision mitigation to be disabled at 51k miles, error code U3000-49

All systems associated with the Lane Keeping Assist System are intermittent. No event caused them to initially fail and no discernible conditions cause it to fail currently. The system works intermittently.

A latch inside the driver door of the car broke and my husband was unable to exit the vehicle. There was no reason for this part to break, no collision or rough use of the door. We just drove from our home to our destination without incident and the door would not open when we arrived. The dealership had to replace the broken part.

In 2020 I was driving in Sequoia national forest and hit a small pothole/erosion hole in front of a gate at approximately 2-3mph. I slightly bottomed out the car. The airbags deployed. Mild abrasion friction burns on my wrist. My wife's airbags in the passenger seat also deployed, but since we had zero forward momentum they didn't even contact her. I was told by Honda that this is my fault and that their airbag system only deployes when it should, and ultimately just filled an insurance claim. I was extremely ignorant of how not road safe my car was, and drive it home. The car was towed for repairs. I just recently learned about this complain line, so I'm submitting now in early 2024.

Fuel Pump quit working while driving and caused my vehicle to stop in the middle of the road. My vehicle had 63000 miles when it stopped working.

My 2020 Honda Odyssey started showing SRS problem error on its 4th year of ownership. Since it’s not under warranty after 3 years I spent close to 1k to replace SRS computer module by dealership from where I purchased my car. Same error came back a month later and again I took it to dealer and they said it has loose connection on cable and fix the loose connection. About a month later SRS light came back again and then I took it to dealer and he said connection is good but one of the connector is not sending the signal to SRS module. They asked me to replace entire SRS module wiring which will be around 4k which might resolve this problem. I reported this problem to Honda Corporate and waiting for their response. Since it is SRS problem, I am more concern to drive the my car with Kids. If I meet an accident and airbag won’t deploy then it will be risk for me and my family.

The heads up unit, navigation and audio system completely shut down after Network connection lost message. This started happening after recall of a cable, before it was fine, same cable was replaced under warranty a year ago. The problem is reproducible, simply driving vehicle and hitting a bump on passenger/right side cases the system to malfunction, disconnect audio, and eventually whole system shutdown and restart. I will take this back to the dealership but electronics in Honda Odyssey has been unreliable and feels like a safety risk.

Car stuttered and completely stopped running on the road. Cops had to come and direct traffic around me while my car had stopped. Towed the car to the dealership and the fuel pump was identified as the problem. Car has 63000 miles on it.

There is a water leak in the factory seals of the rear tailgate which causes the Power Tailgate Control Module to fail. The tail gate can no longer be closed/latched and requires replacement and sealing of the water leak.

I have a concerning noise from my car's engine that I’ve already brought in for diagnosis. Knocking/ticking/rattling noise on stand-still acceleration at relatively low speeds/under light load. Does not duplicate when revving in park, only under light load. Sound present with HVAC on or off. Does not make noise when cold or after long trips. Honda seems to be aware of this issue and has remedied it through work involving the crankshaft bearings and possibly other components as it relates to their service bulletin 23-097. The problem is that my vehicle falls outside of the stated range of production years as mine is a 2020 model year, but the likelihood seems quite high that the engine in my vehicle is suffering from this exact problem. The service department refuses to help me and the corporate line I've contacted through email me simply refers me to the service department. I just spent $38,000 on this vehicle with 30,000 miles and I have no other recourse at this point to remedy this.

The auto idle feature cuts out the engine in stop and go traffic and will not restart. This has happened on numerous occasions, creating unsafe conditions for traffic.

Was driving to work while raining.hit a water puddle hydroplaned, The stop brake warning light came,vehiical slammed on the brakes, and the steering wheel locked up. 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.

In my area, there has been lots of heavy rain. There was a water leak on the interior rear driver side, causing the tailgate control module (TCM) to fail part # 74970-THR-A12 The tailgate trunk or 5th door is not working, will not open, will not activate. I took my 2020 honda odyssey my local dealership but no help. Many vans from Honda, years 2018-2021 are having this very same issue. Please help Me resolved this matter. Honda should have a recall on this and replace at no charge.

9/29/23 Vehicle left my wife stranded on in parking lot would not start. Had vehicle towed to garage. Garage had to replace the fuel pump as the impellers were no longer working. Vehicle would not turn over acted like bad gas, shop put in fresh gas still would not start. Found failed fuel pump. 1/04/24 Called Honda 888-234-2138, rf teh 12/23/2023 recall on additional 2.8 mil units including my odyssey. spoke to angel at Honda, he told me my unit was the only one out of millions of units not affected by this recall, even though my wife was left stranded in a parking lot. I have the invoice but your system will not allow me to upload anything. [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car stalled when stopped at a red traffic light. This happened on 2 occasions, 11-3-23 and 12-9-23. The second time other cars behind us had to go around us while we tried to restart the car which put them at risk of being hit by cars in the other lanes. There was no warning. I took the car in for regular maintenance a few days ago during which the dealership did a multi point inspection but did not discuss this issue. Yesterday I heard about the fuel pump recall and think this might be the same issue. I called the dealership today but they said our car is not under the recall. Our car is available for inspection upon request.

Idle stop caused engine to stall 3 separate times leaving me stranded in busy intersections making it difficult to restart vehicle and move safely out of the way. Initial start up checks come on, asked to put car in park, step on brake to restart car, car won’t restart. Once happened at night and shut off all my lights for 30 seconds making me not visible for cars coming up to me.

The entire ADAS system has begun loosing sensing capabilities for a time period but start working again later. It comes and goes regularly at this point. This inconsistency could cause and accident. There are system problem warning lights on the dash when the system is down. The car is too new for this issue. The dealer reports that the front camera is the issue but I would think it has more to do with the wiring possibly shorting out.

While stopped in preparation to make a left turn across traffic on a 4 lane road, our 2020 Honda Odyssey engine stalled- the engine idle stop function did not restart the engine as designed. We had to restart our car, but the car did not immediately restart, it took us 2-3 attempts. There was no prior warning or indication there was a problem. We could have easily been hit by another car, injuring my wife and children. Our system is available for inspection, we have not had it inspected yet.

Driving in traffic, switched lanes into a turn lane and came to a stop. The van put itself in park and wouldn't do anything for 5 minutes...the van kept running. It couldn't be shifted out of park, it couldn't be turned off. After approximately 5 minutes was able to put it back in drive and drive away.

My vehicle has the engine idle option and shuts the engine off when idle in traffic or at traffic lights, etc. There have been incidents where the engine doesn't just shut off but it powers off the entire car and doesn't want to turn back on. My battery is fine because i just had service done on it and they tested the battery and its 100% fine. This issue is not a battery issue for my car. I literally had PTSD when the car shut off though because it happened at a location on the roadway where i had previously been rear ended in another vehicle and after my car shut off this time - my anxiety was very high that day and i was literally shaking. I was scared not knowing what was wrong with my car.

I had a Recall on my 2020 Honda Odyssey Vin # [XXX] for NHTSA Recall # 23V-431. The recall was for rear camera failure. The Fix was to replace MOST cable harness. In Early October 2023 my rear view camera did fail and no longer conformed to Federal Motor Vehicle Safety Standard No 111, “Rear Visibility” I took my Honda Odyssey to Serra Brighton Honda for repair , Serra Brighton Honda replaced the cable and it did not fix the problem. I was told it was the camera which was not part of the recall and was charged $302.42 for replacement of the camera, Invoice # [XXX]. It only seems logical to me that if “Rear Visibility” is a Federal Motor Vehicle Safety Standard , the camera should have been included as part of the fix. It could have been possible that the cable shorted out and damaged the camera’s electronics. My Honda only has 21,500 miles and is always stored in a garage and has never been in an accident.

All advanced driver assistance systems have stopped working while driving. This has also caused brake and transmission errors to show.

LKAS, Adaptive cruise control, forward collision warning, automatic emergency braking, lane departure warning all malfunctioned. Dealer inspected and determined it is an overheated camera that controls all the mentioned safety functions. This happened while driving on highway and has never worked again. I did confirm with the dealer this is the 3 instance they have seen of this in the past 3 months.

My wife was driving our honda odyssey on a state highway and it began lurching and drastically reduced speed while in 65 mph traffic. The vehicle almost created a large accident as it uncontrollably and suddenly reduced gears and instantly slowed well below the rate of travel of the vehicles on the road. She managed to pull over on the side of the road but was unable to move the vehicle . There was never a check engine indicator or any other warning signs prior to this happening. The vehicle was towed to the local honda dealership in Scranton PA. Today the service center there stated that the transmission fluid was charred and burnt up gears in the transmission. This is a huge safety concern as there was no warning signs of the issue until the vehicle rapidly and suddenly shifted down gears and slowed to almost a complete stop along the highway. The vehicle is only 3 years old and is 900 miles over the powertrain warranty. Has there been a check engine light or any indicator we could have had the problem addressed before it became catastrophic and put my families lives in jeopardy. The vehicle has been regularly maintained

The contact owns a 2020 Honda Odyssey. The contact stated that on several occasions while driving at various speeds during rainy weather, he attempted to defrost the windows; however, the HVAC failed to operate as designed with warm air coming from the HVAC system. As a result, the windows failed to defrost as needed, making it difficult to see the roadway. The vehicle was taken to the dealer where it was diagnosed and determined that the blower motor had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The manufacturer was notified of the failure and advised the contact to take the vehicle back to the dealer for assistance. The failure mileage was approximately 32,400.

Occasionaly car will not start of up after Idle Stop engages. Collision warning flashes then leaves us stranded in intersection. Very Danagerous.

Vehicle driver side sliding door has issues closing. Mentioned to dealer, but dealer dismisses it as possibly from water residue after car washes. Door needs to be manually closed with pressure to latch. Vehicle has lost all electrical function while in Economy mode while in idle mode while at red lights and also while parked with accessories running. Vehicle batter life was verified and in excellent condition at battery replacement shop.

I have had 2 major issues, the idle stop feature has multiple times caused my car to stall. It has even happened on the highway during traffic where the car went into idle-stop mode and would not restart the engine. Last week it happened again on a major road and the only way to restart the car is shift to park in the middle of a busy 4 lane road, turn off the car completely and then attempt a restart. The other issue was with the rear sliding door, my 3 year old son closed the automatic sliding door by pressing the button and his hand was crushed/ stuck until I was able to reopen it. I have called Honda who told me I could have it looked at but it would cost me for the diagnostic and repair if needed due to the fact that it was one month past their 3 year warranty period.

My rear entertainment does not show dvds playing however when I Insert a dvd I hear audio but the bluray rear entertainment appears to be stuck in loading setting and does not show a picture. Honda said there is a recall for this issue however My vehicle is not listing the recall. It is distracting to the driver and passengers causing stress.

The contact owns a 2020 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 23V431000 (Back Over Prevention). The contact stated that on several occasions while driving at various speeds, there was a static sound from from the radio. The vehicle was not diagnosed. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000.

When the car engages the Idle Stop feature and shuts the engine off, the engine does not restart immediately once the brake is released. This has happened multiple times but the last time a message appeared that said to change gears and restart the car. In the meantime the vehicle was in traffic and stopped for over a minute before it could be restarted. This put us in danger of a rear end collision as other cars were wanting to go.

At a stop light the engine idle shutoff feature shut off the engine. Then a few moments later the entire vehicle shut off. I could not turn the vehicle back on after trying several times to do so. After about five attempts the vehicle turned back on in park gear. During this time the light turned green and the vehicle would not turn on, cars behind began honking. This has happened a few times since owning the vehicle. I was dead in the middle of a busy intersection. I have asked the dealer to look at the electrical system as there have been several anomalies but it checks out fine. I replaced the battery thinking that might be the problem but did not work. I believe it is the same problem as PE22005

I believe the idle start stop malfunctioned. The three times this has happened, I have been at a stop light and when I released the break and attempted to accelerate, my car turned off. It took several tries to get the car started and I felt very unsafe. In researching online I've discovered that I am not alone and am concerned that Honda hasn't had a recall to address the problem. Are they waiting for someone to die or be severely injured before addressing the issue?

This event happens intermittently, and has occurred approximately 4 times. When the issue occurs it happens as follows: 1. Vehicle comes to a complete stop, and driver's foot has depressed brake pedal 2. Vehicle automatic start/stop feature turns off engine. 3. Driver lifts foot off pedal, begins to apply pressure to gas pedal. 4. Vehicle automatically re-starts engine 5. Vehicle starts to move forward, and then lurches - it feels like the brakes are being applied by the vehicle independently from the driver's action. 6. Alerts start appearing on the dashboard - a message that the Forward Collision Warning System has been disabled and the "BRAKE" light starts flashing for 30 seconds to a minute afterwards. 7. Vehicle then starts to move forward without issue, Collision System message goes away, but BRAKE light on instrument cluster continues to flash for a period of time. This issue presents a safety risk as the vehicle does not respond to driver's input as expected when this issue occurs, appears to brake on its own. Interferes with a driver's ability to move through an intersection after stoping. I have taken the vehicle to a Honda dealership (Penske Honda, Indianapolis Indiana) and they were unable to replicate the issue and did not find any stored error codes in the vehicle comptuer.

On at least 5 occasions the car has not restarted after going into auto idle while stopped. Normally after pressing the brake pedal all the way down while stopped, the engine will shut off and then restart after releasing pressure from the brake pedal. When it doesn't restart, all the lights on the dashboard come on and you can't do anything. It won't restart if your press the start button and you can't shift it to neutral to push it out of the road. Eventually it will restart by pressing the start button. I have not had this problem if I turn off the auto idle, however you have to manually turn off the auto idle every time you restart the car.
