2021 Honda Odyssey complaints

The contact owns a 2021 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags). The contact was concerned about driving the vehicle. The contact called the local dealer, who stated that parts for the recall repair were sent to the dealer sporadically. The contact called two other dealers, Honda Marysville Service Center (640 Colemans Crossing Blvd, Marysville, OH 43040), and Germain Honda of Dublin (6715 Sawmill Rd, Dublin, OH 43017). The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure.

I hear a popping/crackling noise from the speakers then I get complete network loss for my backup camera, my dvd player, my clock, maps etc.System does a report after 5+ minutes. Message displayed before everything goes black is Network Connection Lost and MOST Net Off. This issue is ongoing and seems to happen now every day sometimes multiple times in a driving session. It just started about 2 weeks ago. There is an active recall for this exact issue for 2021 Honda Odysseys but my VIN does not seem to be included.

My van is braking when there are no cars or dangers in front of it. Sometimes there's a metal plate on the ground or speed bump when it brakes. Other times there's nothing in front. The car slams on the brakes and I cannot override it with the gas pedal. This puts my kids and I in danger of being rear-ended. This most commonly happens around 7:30am or 4pm when I'm taking kids to school or dropping off. I'm often in the carpool like or headed to the school when the car slams on the brakes. It's very frightening. The dealer cannot find an issue and cannot replicate the problem.

Vehicle lost power resulting in the vehicle automatically going into park and powering off while driving. This has happened multiple times. In addition, we will get strange electronic codes. Tested battery and systems successfully, but problem persists.

Dealership has been unable to complete recall repair due to parts being unavailable. The original recall is over 18 months old.

When attempting to restart from the autostop function (i.e. the fuel economy function), the vehicle fails to restart successfully. This has happened on multiple occasions. It is not a battery problem and I have had the battery tested and even replaced (by Honda) and the problem has continued. The vehicle will stutter, stall or even completely shut down. This has happened when I have been at intersections and on busier roads or even in traffic on the highway. Its very concerning to me and seems extremely unsafe. No warning signs come in this scenario until the vehicle shuts down and the regular dash light engages indicating the engine is inoperable. I have today's date below but this has been happening consistently the last several months.

Can has been making a popping noise that can be felt in the steering wheel for 2 years. Honda has told me nothing was wrong after taking it in 4 times. Now my car keeps stalling at lights, sometimes it takes a while to get it to restart, and they can not figure out why. They keep saying the battery is fine and diagnostics finds nothing.

Vehicle applied brakes for no reason. Lost ability to see reverse camera during backing up. Half of the instrument cluster went dim to become barely visible. Radio screen freezes randomly. Engine cuts out or shudders intermittently.

Approximately May 2023, while pulling away from stop light, heard loud pop (like gunshot inside vehicle) and vehicle shuddered/jolted. It feels almost like someone hit vehicle with sledgehammer. I looked underneath but no issues found. No bump in road was hit at the time. December 24th 2024, while moving at less then 5 mph, heard another loud pop and shudder/jolt. Someone sitting in the back thought that something fell on the vehicle. This time noticed that left rear tire was into wheel well with vehicle unloaded. After pulling wheel, found left rear coil spring broken in 2 places. Believe broke first in 23 and again in 24. At time, we were 1200 miles from home and needed to delay trip so Honda in Killeen TX could repair. Dealer service advisor stated they had never seen anything like that except from crash. June 19th 2025. On highway doing 70-75 mph when heard another loud pop and shudder. No pot hole or any significant bump hit. Stopped, pulled wheel, and found right rear spring broken. Honda dealership in Marysville OH unable to find new spring either through OEM or aftermarket. We have also been unable to find aftermarket or junkyards. Being told that there is a nationwide backorder and no eta for when replacment parts are going to start being available. So being forced to continue driving a vehicle that is unsafe. First this does not seem normal for springs just to randomly break. Second for a critical suspension component on a relatively new vehicle, why is manufacturer

While stopped at a stop light at an intersection in our 2021 Hond Odyssey, the idle auto off feature kicked in, and then as we let off the brake and went to hit the gas to move forward the car shut off completely. The car had to be restarted by applying the brake and pressing the start/stop ignition button. This is not the first time this has happened with this vehicle. This also happened a series of times in 2023 and Honda performed a series of software updates, replaced the battery, and replaced a sensor on the battery. However, now two years later the idle auto off issue occured again.

The contact owns a 2021 Honda Odyssey. The contact stated that while attempting to start the vehicle, the engine failed to crank. There were no warning lights illuminated. The vehicle was towed to a local dealer, where it was diagnosed, and the contact was informed that the starter was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 66,000.

There is a message that pops up in our front touch screen panel " com.honda.auto.hars has stopped" which is not allowing us to use the touchscreen panel.for anything - from making or receiving calls , navigation , etc .. , which makes it hazardous to drive the vehicle on the road & not able to use hands free. We tried factory reset & also using USB drive to update , but the car is not recognizing the USB drive & also says that our system is up-to-date!! We are not able to find a solution . Please help . Advice needed.

The vehicle's Auto Idle Stop (AIS) malfunctioned. The vehicle stalled and required a complete "shut down" to restart. The vehicle was first in line at a traffic light. The AIS system engaged. When I took my foot off the break to "go" when the light turned green, the car stalled. An error message popped up, indicating that I needed to shift the car into "park". I did so and the car did not start. I attempted to turn the car off several times, while in park and my foot depressing the break pedal. The car would not turn off. After three minutes of attempting to turn off the car and waiting, I was finally able to successfully start the car. I was traveling with my four young children, three of them in child car seats. I was nearly rear ended by one vehicle, despite having my hazard flashers on, because my car stalled at a traffic light when it was green. Two cars drove around me who were also stopped behind me at the traffic light. Another car came up to the traffic light and my vehicle and nearly rear ended me with my four young children in the car. This is the third time that this exact issue has occurred in my car. I brought it to my local Honda dealership on the same day that the issue first occurred. They inspected it but were unable to replicate it. They said they would make note of it but had not heard of such an issue. I had no idea this could be reported on this website. I was never told about this otherwise I would have reported this on the day that each of the two prev

The contact owns a 2021 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags); 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 manufacturer was not made aware of the issue. The contact had not experienced a failure.

2021 Odyssey EXL the Electric parking brake 'issue' warning comes on while driving and collision mitigation warning / lane assist switches off and flashes in console; when this happens the car continues to run but the dashboard warning lights comes up for Parking brake / Collision Warning and or Lane assist. It gets cleared after I turn on/off the car couple of times and drive for approximately 5 miles. Those features had to be turned on manually, once the car is in parked mode, again. The issue started in the car at around 48K miles. Never had any issue with it before that.

2021 Odyssey EXL shuts off completely in traffic stop and go conditions. Happened three times in a 2 week period. Twice in city roads at traffic stop light and once in highway when the cars are in stop / go mode due to heavy traffic. Engine switches off completely and puts itself in "P" mode, all light comes on as if in accessory mode, radio switches off, all doors unlocked. To get going, the driver had to press brake pedal and start the car again (via Engine Start /Stop button). This issue started in the car at 43K miles. Never had any issue with mine before that. But it is scary especially the engine switch off in highway and traffic stop light.

After my van sit at home all day while it was raining. I went out side to put something in the back of the van and the tail gate wouldn't open had warning symbol on the dash board. I only have 61,729 miles on my van and no accidents

Tailgate would not work (electronically or manually) Other Odyssey owners have had similar problems, some included tailgate opening on its own There were no problems until it just wouldn’t open one day Dealer replaced module for $700+

In stop and go highway traffic. Engine cut off when at a stop during "Ecoboost." Had to turn off car and restart. Was able to restart with no problem. Full tank of gas. Fresh oil. No error messages before and after

It started that all the sensor in our car started to go off. We were told we had a bad battery, even thought we had replaced it new just last year. Once we had the battery checked and alternator. The sensors started to act up again, out tail gate started to malfunction. Wouldn’t automatically close. A few weeks ago driving down the road the tail gate opened and the anti theft system started going off while the car was running and still going. Come to find out there is a water leak in the rear that has gotten into the rear fuse box and has cause substantial corrosion. The latch to the tail gate is broken. Honda is telling us our extended warranty doesn’t cover any of this, even though it is common knowledge, that the water leak is a known problem from 2018-2021. We just found out a few days ago.

Auto Idle Stop not restarting after shutting the engine down.

Car has completely shut off when the auto start/stop engaged after coming to a stop at a red light/stop sign on multiple occasions. Everything shut completely off, no radio, lights, etc. Had to push the start button multiple times to turn the car back on. Please investigate as I have read of this happening to many other people with 0 solution from Honda. This is a defect and should be recalled/fixed.

Took my car to dealer 4/15/2024. Dealer stated no stock parts available. Dealer never contacted me anymore.

All of my assist lights just came.on one after another saying there was a malfunction with the emmision light continues to go.on go.off even after I paid 580 to have the car serviced for the assist lights. Now the lift gate stopped working three weeks ago yesterday with all the rain that poured now the lift gate is open and will.not latch.

The power trunk stopped working. The car starts warning me about a power tailgate problem. I have seen this issue reported by others as well. The warning light comes and goes randomly. The power trunk does not work at all anymore I have to open and close the trunk manually. I am concerned about the trunk malfunctioning further.

Contacted dealership in Newburgh NY for recall. The rep pushed back making me wait 8 weeks. Dearlership in Middletown NY did not return call.

This happened twice to us. While stopped at the red light the car suddenly shuts off and won’t start. We had to press and hold the start button for 5 seconds for the van to start. It appears that on both times the car just stalled.

On 1/31/25 our rear tailgate automatically opened upon parking the car in our garage. Later that day, the tailgate would no operate properly and had to be manually opened. The key fob was functional and could operate all other doors in the car, except the tail gate. Later that day, while the car was parked in our garage, the tailgate started operating by itself, without pressing any buttons on the remote control key fob. It would open and close by itself and repeat the entire sequence over and over again. Upon turning on the car, the display identified a Power Tailgate Problem. The problem was reproduced by the Olathe Kansas Honda dealership. We took it to the dealership today and they diagnosed the problem, stating it is a Gate Control Unit failure (error code P1378 and P1379). Dealer confirmed what we experienced. We documented the safety problem via video. We were able to temporarily fix the issue by disconnecting the car battery overnight and reconnecting it the following morning. Safety concerns - This is a concerning issue as the tail gate could open by itself while driving, and/or could open by itself when you have the car parked in public, allowing theft of any items left inside. It could also open while someone is driving along a parking lot and cause an accident. There was no warning light prior to the malfunction of the tail gate control unit. We have found online that there may be a class action lawsuit regarding this issue.

I was driving in light snowfall when several alerts notifying me that the radar sensor was not working. This is common in snow fall. Later I cleared off the radar unit cover (The Honda logo on the front of the car). The alerts remained. I took it to the dealer and they dubiously told me it was "damaged by snow". This is impossible. It was light snow. There was no collision or impact. This device should be durable. It has no moving parts. But Honda wants me to believe that it simply stopped working from driving in a light snow. They want $1300 to replace. How do I know the next one won't conk out after the first snowfall? These units should have a lifetime warranty with only exceptions for collisions or impact damage. If the unit is damaged by snowfall, it's clearly too fragile and should not be on the market. It's a HUGE safety concern that the vehicle's advertised safety systems can be toppled like a house of cards from one light snowfall.

Power tailgate problem displayed on dashboard. Suddenly stopped working. Constant dinging noise when driving.

On 28-Dec-2024 I noticed the power tailgate stopped working on my 2021 Honda Odyssey. I tried to press the power tailgate button on the key fob, the button on the driver's side control panel, and the button on the tailgate itself, but none of them works. I did some research online and found out it's a common problem in 2018 to 2021 models and the cause was the failed Power Tailgate Control Unit due to water leakage through the cracks on the vehicle body. I opened mine and found there was water in the control unit box which might have caused short on the circuit board. I bought a new control unit a week later and it fixed the issue.

The children message that the radar is obstructed, I did the clean where is the radar is but the issue still.

The sliding door closed on my child's hand cutting the top of his finger off down to his finger bone.

The contact owns a 2021 Honda Odyssey. While the contact’s wife was driving approximately 70 MPH, the vehicle began to lose automotive power with several unknown warning lights illuminated. The vehicle was driven to the shoulder of the roadway before stalling. The vehicle was unable to be restarted and was later towed to the local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 72,000.

The contact owns a 2021 Honda Odyssey. The contact stated that on one occasion while the vehicle was parked, the rear hatch failed to open. Additionally, the contact stated that while driving at approximately 35 MPH, the rear hatch opened inadvertently. The contact pulled over to the side of the road where the door was closed but failed to securely latch. The vehicle was taken to a dealer where it was diagnosed and determined that condensation had leaked into to the driver’s side of the gate and damaged the rear gate control unit. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 46,500.

A few weeks ago, the car I was driving steered itself dangerously close to a pedestrian in the breakdown lane. I was driving my wife’s car which I drive infrequently. This model has a lane-keeping function which steers you back into your lane if you veer. I was rounding a bend in the right lane on a highway as a man appeared on the edge of my lane, changing a tire, partially in the roadway. I was pointed away from him so I let the car coast out of his way but the car literally turned the wheel and fought me as I tried to veer left out of the man’s way. It all happened in less than a one or two seconds. Had I used the turn signal the system would have temporarily disabled itself. I shared this story on Facebook with my friends and several friends reported nearly identical issues with lane keeping driving them towards a hazard.

Drive side rear power door stopped working. Upon using handl to opperate as usual the door stopped only a few inches open. A gentle shove got it open and opperational. The next day it did the same thing this time refuding to eithe ropen completely or re-latch. My children were in the car with me on the way to school and the door could not be opened to let them out or closed to safely proceed on our route. We began diagnositcs and found that the door continued to be problematic; opening just enough to be unlatched but nor going further, opening only half way and locking in place, or openeing completely then refusing to close... the door being in manual mode or power mode makes no differnece. after complelty disasembling the door/panel to check calbles and motor, checking fuses etc we put it all back to gether and suddenly it worked fin for about a dozen tries. HOWEVER the passanger side rear door (perviously untouched) suddenly developed the same problem. Now both doors will not function in either power or manual mode and I am waiting on the dealership to look into possible computer issues.

After having the Honda Dealership perform an oil change and software update 23-008 (updating the Auto Idle Stop Software) last week, my engine stalled while at a busy intersection (PA turnpike/70 junction) during a road trip. At the long stop light the auto idle function engaged and the engine turned off. When the stop light turned green and I lifted my foot off the brake and pressed the gas the engine shut down and automatically went into Park. I had to press the start/stop button to fully turn off then turn back on the car to get the engine to restart. This is with a giant semitruck honking right behind me. The auto idle feature does not work. It sounds terrible every time the engine restarts after it has been engaged. There really should be an option to allow users to permanently disable it, and not have to remember to turn it off every time they start the car--terrible user experience.

After the PGM-FI update was put into our car, the engine cuts out entirely while at stop lights and will not wake back up. The Honda dealership is saying that there is nothing they can do.

I attempted to have recall repair work done at the dealer where I purchased the vehicle a few months ago and they told me the part will not be available until 2025.

I purchased a 2021 Honda Odyssey with 55,000 miles on it. At 57,000 miles with normal driving conditions, I heard a metal on metal noise on rear passenger side. Upon taking it to the mechanic, both rear springs were rusted & broken - essentially giving my van no rear suspension and making it very dangerous to drive. I had to find a new vehicle for my kids for a month and a half as there is no aftermarket part. Honda would not find the part for me and wanted me to work through the dealership, but I did not have the time as this is family vehicle that I need each day. I had an independent mechanic find a pair of springs from a junkyard & he confirmed that in his 40 years of servicing exclusively Hondas, he's never seen springs fail like this at this mileage. He expected a faulty part. I drove this vehicle multiple times thinking that it was safe & only something loose in the car. At any moment, the suspension could have failed & caused a serious accident. I do have the springs & have attached photos. Component has not been inspected by anyone other than myself & mechanic. No prior warnings or messages noting a problem.

My Honda Odyssey is experiencing an issue where it intermittently fails to restart automatically after coming to a stop and engaging the idle stop feature. Despite following Honda's recommendations, which included applying Service Bulletin 23-008 (updating the PGM-FI Idle Stop Software) and replacing the battery, the problem persists. I've also had the vehicle inspected at two different dealerships, with no resolution. I discovered Service Bulletin 23-009 on your website, which directly addresses this exact issue and extends the warranty for the Ridgeline, Pilot, and Passport models. Given that my Odyssey shares the same engine, it's concerning that it's not included in this bulletin. I believe it's unfair that I'm being forced to pay dealership fees to diagnose and fix a safety issue that Honda has already acknowledged and addressed for other vehicles with the same engine. I urge you to reconsider the exclusion of the Odyssey from Service Bulletin 23-009 and provide a solution that doesn't burden owners with unnecessary costs.

After a slight rain, the error of Radar Obstructed is being displayed. Can’t get this error removed or fixed. After searching more I found out that: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of

Took my odyssey to the local dealer a few months back for the recall and dealer told me they wouldn’t have the part until next year. Now this has caused an issue to where my whole airbag system is short circuiting and the dealership wants to fix all the other issues and not fix the open recall. Family safety is at risk.
