2020 Honda Odyssey Complaint Log

We hit a pot hole on a city street going 30-35 and it caused the airbags on both sides of the van to deploy. There was no damage to the van, rim, or tire. In addition, when the passenger airbag deployed my wife received a burn on her arm.

I just started up the car one morning and had multiple sensor warnings. Brought it to the Honda dealership and told it was an internal sensor camera malfunction and wanted $2000+ to fix it. This honestly should be a recall as I’ve had several other Honda owners complaining about the same thing which is a huge safety concern

It’s starting raining and the brake system light came on and hasn’t went off.

Drove to grocery store, did not have any codes, when I got back in my car and restarted I received these 5 errors: Adaptive Cruise Control Auto High Beam Problem Lane Keeping Assist Problem Collision Mitigation System Problem Road Departure Mitigation System Problem

The multicamera display unit is defective. It operates several systems and cause multiple warning issues. I believe the design is flawed. In addition to the warnings, both the display for driving information ( speed, rpm, temp, etc.) go blank and the AV unit (radio, entertainment, etc) shuts off too.

WHEN I BOUGHT THE VAN USED IN 2023 AT A DEALERSHIP, THEY WERE WORKING ON THE TAILGATE OF THE VAN. THEY STATED IT WAS A FACTORY DEFAULT THAT THE MODULE HAD. THEY DID NOT GO INTO FURTHER DETAIL. I STARTED GETTING A MESSAGE ON THE DASH PANEL THAT THE POWER TAILGATE SYSTEM HAD A PROBLEM. i ALSO GOT MESSAGES STATING THE THEE REVERSE COLLISION SYSTEM STOPPED WORKING, TRANSMISSION SYSTEM HAD PROBLEMS, THE KEYLESS STARTING SYSTEM PROBLEMS. THIS WAS HAPPENING AFTER A RAIN OCCURANCE. I TOOK IT TO THE HONDA DEALER, THEY DID NOT KNOW HOW TO FIX THIS. i TOOK IT TO MY MECHANIC AND HE FOUND WATER IS GETTING THRU THE ROOF RACK RAIL GULLEY, LEAKING DOWN THE BACK DRIVERS SIDE INTERIOR PANEL ON TO THE TAILGATE CONTROL MODULE. i HAVE TO TAKE THE VAN TO A BODY SHOP, SO THEY CAN FIX THE AFFECTED AREA. i HAVE THE PART MY MECHANIC REPLACED. IT IS CLEARLY WATER DAMAGED. THE DAY HE FIXED MY VAN, IT HAD RAINED AND MALFUNCTIONED AGAIN. RIGHT NOW I HAVE THE MODULE HANGING IN THE CARGO AREA, OUTSIDE OF THE INTERIOR PANEL, SO IT DOES NOT GET WET WHEN IT RAINS.

I was stopped at a light at a busy intersection and when I went to drive when the light turned green, my van did nothing. It had turned off the engine when I stopped at the intersection. I tried to switch gears and it wouldn’t change. I was kind of panicking because I was holding up a ton of traffic and my toddler was in the backseat so I can’t remember exactly what was happening on my dash. I would turn the car on and off but I could not get it back into drive as the engine would not restart, but all of the electronics were still working. Finally someone offered to jump the car with one of those portable battery jumpers and that worked. I drove straight to Autozone to see if it was something their machines would pick up on but they couldn’t find anything wrong. The dealer also couldn’t find anything wrong. I believe this is related to the auto idle stop feature.

On multiple occasions, after stopping the vehicle (for example at a red light), the engine would stop and not restart. After several minutes of frantically trying to restart the vehicle in dangerous situations (stopped in the middle of traffic and nearly rear ended multiple times), the vehicle would eventually start the engine. Bottom line - when stopping at a stop sign or red light, the vehicle turns off the engine and does not restart properly - placing all occupants in a dangerous situation.

The multipurpose camera above the rearview mirror has stopped working. It controls several systems including; adaptive cruise control, automatic brake system, forward collision warning, lane keeping assistance, lane departure warning, automatic high beam control. Every time I start the vehicle I have to clear 6 different malfunction warnings and non of the effected systems will function. There is an increased risk of accidents. I just had a vehicle diagnostic ran at Flow Honda of Charlottesville VA and they quoted me a price of $2,060 to replace the part.

Started the vehicle on 7/3. Multiple warning lights show on my dashboard: 1. ACC problem 2. Collision Mitigation Problem 3. LKA Problem 4. Auto High Beam Problem I took it to Purrfect Auto (as I had just had work done). They claim it is a software issue (per Honda) and did a reset of the dashboard (I was not charged for this). Problem was fixed. Later that day when I started the car, the warning lights came back. About 4 out of 5 times I start the car, the warning lights return. I had a long road trip (8-hours) a week later. So when I started the car and the warning lights came back, I would turn off the car and open and close the door (to turn off the computer). After I turned off and on the car 3 or 4 more times, the warning lights weren't on, so we started our road trip. This is a safety issue because I am now used to 4 years of Lane Keeping Assistance and Collision Mitigation. For the first time in 4 years, I experienced *3* near collisions with other vehicles due to the failure of these systems. This issue was inspected by the mechanics at Purrfect Auto. There were no other warning lamps, messages, or other symptoms of the problem prior to this failure.

I was driving, and there was a car coming from the opposite direction in their own lane, and nowhere near my car, and the automatic braking slammed on the brakes. This was just the worst instance of it malfunctioing.

Front Camera failure resulted in failure of Adaptive Cruise Control Automatic Emergency Braking Blind Spot Warning Forward Collision Warning Lane Departure Warning Lane Keeping Assistance Parking Collision Warning Rear Cross Traffic Warning

There are five warning indicator on the dashboard complaining about Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance. I took the car to the Honda dealership, and they acknowledged that they were due toan internal failure of the multipurpose camera.

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 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.

On 6-11-24 The warning lights cycle through Auto Highbeam problem Lane Keeping assist Adaptive Cruise Control Collision Mitigation System problem Road departure Mitigation System problem Earlier in the day I had maintenance at the dealership performed on my car: brake fluid , trans svc,new tires and alignment, oil change and rotate tires, ac filter change, air cleaner element replaced. I went back to dealer on 7-1 and was told it was a multi purpose camera failure. This had not previously occurred until immediately after the maintenance work was performed.

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.

Rear door would not open with key fob, button on the dash or the button on the rear door. Then it randomly opened one morning and would not close. Through research I found out there is a problem with water leakage, the vehicle is not properly sealed. Resulting in a damage MICU. I was able to replace the MICU and the rear door works now. I believe this is a safety concern, how can I drive with the door not latching. When I unplugged the MICU water poured out and you can see rust in the fender well where the MICU sits.

The front camera/sensor broke and is not covered under Honda’s warranty. This affects the adaptive cruise control, lane keeping assist, collision mitigation system, road departed mitigation, and auto high-beam.

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.

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.

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.

After any kind of weather event that produces water (rain, morning dew, snow melt), the car battery is dead the next morning. It jump starts the following day and will be drive normal until it sits overnight and the dew settles back in. There has been evidence of water leakage from the rear cargo door and the power door does not function. The only way to open the door is by removing the plastic cover and utilizing the mechanical lever on the inside of the door. The problem is a daily occurrence with dew and other water events. We have not gone to any automated carwashes, strictly handwash the car. No warning lights have been produced.

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

Auto Idle Stop (AIS) system. had many of the other same symptoms that people reported. our car would go into idle mode and then it would not restart. I would have to turn the car off I tried to do various things just to get it started again. this happened one time was the exited the highway and also happened coming out of a car wash location. I took it to Honda and they said because of the idle stop functionality the starter went bad and they had to replace that. I was compensated some money from Honda but I believe I was only done so because they knew something was wrong and I really believe there should be a recall for this. it is completely unsafe and very scary when it happens especially in the middle of traffic. our starter was replaced because of this issue on November 5th 2024, but the symptoms had been going on for that whole calendar year prior

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 can’t find the problem and we have to pay $1800 for those rather high-priority safety features like knowing how fast you’re going. I also have a newly licensed teenage driver and another who will get her temps in 2 months. I can’t even let them drive our vehicle because they certainly don’t have the experience necessary to drive with no speedometer. We live in a state that doesn’t allow handling a phone in any way. This vehicle helped me comply with that & now I must use a phone to show my mph

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

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.

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

The outside mirrors had a recall for potential detachment. My driver's side mirror detaches sometimes even after the replacement. When I contacted Honda over this issue, they told me that they can't take my complaint and I should go back to the dealer which replaced it.

Multi-Purpose camera has failed according to Honda dealership. No safety features work in the car. You pay for the car to have these features and then they fail after only 3 years? Have been dealing with this issue for almost 2 years now. Honda wants $1,800 for the new camera. This is a safety issue that Honda should be responsible for fixing. No adaptive cruise control, no lane keeping assist, no auto headlights, no collision mitigation, no blind spot alarms.

The car had a leak in the trunk that was not our fault it was not due to an accident but rather came that way when we bought it brand new. We were unaware of this leak and now our entire trunk control panel is flooded and the trunk is totally useless as it will not open at all, not even manually. The only way to open it is to crawl to the back and open it from the inside. I asked Honda for a diagnostic and it cost me $200 for them to tell me “yeah we see this issue a lot in the older odyssey” and that it would cost over $1000 to fix. But this was not normal wear and tear or anything caused from lack of care in my part but it was made that way. I am shocked that when I did research on this issue it was happening to ALOT of people and idk why this isn’t part of the recall list.

+ What component or system failed or malfunctioned, and is it available for inspection upon request? The front camera, which plays a crucial role in the functioning of the Lane Keep Assist System (LKAS), Adaptive Cruise Control (ACC), Collision Avoidance system, and Auto High Beam, malfunctioned. This camera is integral to these systems. +How was your safety or the safety of others put at risk? The malfunction of the front camera caused critical systems like LKAS, ACC, Collision Avoidance, and Auto High Beam to operate unpredictably. This compromised vehicle control, leading to unintended lane departures, unsafe following distances, and potential collision risks. The Auto High Beam system also failed to adjust correctly, creating visibility hazards for both myself and other drivers. +Has the problem been reproduced or confirmed by a dealer or independent service center? The issue has been confirmed by a dealer, front camera malfunctioned and need to be replaced for $2000.

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!

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.

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 contact owns a 2020 Honda Odyssey. The contact stated that the back-over prevention camera and cross-traffic monitor were inoperable. The cross-traffic monitor not functioning message was displayed. The vehicle was taken to the local dealer, who confirmed that the vehicle had been repaired under NHTSA Campaign Number: 20V438000 (Back Over Prevention). The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 34,000.

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.

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.

 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 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.

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.

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.

The contact owns a 2020 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags). The local dealer was contacted and confirmed that parts were not available. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

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.

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.

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

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.

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.
