2018 Honda Odyssey UNKNOWN OR OTHER

Water leaked through manufacting seams on rear drivers side of roof causing tailgate module to malfunction and creating a safety hazard. The rear tailgate would not stay latched or function at all. Took vehicle to honda of Bristol and they confirmed the problem.

I am reporting a safety incident involving the power sliding door system on my 2018 Honda Odyssey. Today, Monday, February 9th 2026, my 3 year old child’s arm was caught and compressed by the power sliding door. At the time, she pressed the interior door button while I simultaneously pulled the exterior door handle. The door began to open, my child placed her arm out, and the door then closed on her arm instead of reversing. The door did not release or reverse automatically. I was unable to open it using the exterior handle and had to stretch to the front dashboard, left sliding door open button to stop and reopen the door to free her arm. Thankfully this didn’t happen on the passenger side sliding door! This resulted in redness, swelling, and pain, and she later woke from sleep crying due to increased pain. She is undergoing medical evaluation. The vehicle is equipped with pinch protection sensors that failed to prevent this injury. This appears to be a serious safety malfunction involving a child. I am submitting this report so the issue can be documented and reviewed for potential investigation. I have not seen a recall involving the sliding doors sensors having this issue.

The car doent accelarate 2 seconds offen

As you are driving the car, out of nowhere, you will hear a very loud chainsaw noise coming from the engine compartment that will last a few seconds, immediately after the noise the car seems to roll as if the engine is not in gear or there is no gas going into the engine even though you are pressing on the gas pedal. This has happened around 5 times over the last month. It doesn't happen every time we drive the minivan. This can be very dangerous as you can imagine that when you are pressing on the gas pedal as you are driving at 30, 40, 60 mph, and the car engine just seems to disengage for a few seconds. I took the minivan to the Honda dealership. They first said to change the transmission oil first to see if that fix the problem. They said if by changing the transmission oil didn't fix the problem then they would need to replace the transmission. Within the first week after getting the fluid changed the problem came back. The minivan is now back at the dealership, and I expect that the transmission is going to be replaced. The minivan doesn't have even 50,000 miles yet. No warning lights has shown up. The problem seems to come and go without any warning.

The Auto Engine Idle Stop causes the car to die while at stop lights, stop signs, in the middle of intersections. Etc. when disengaging the AIS the engine stutters and then displays “Shift to Park” then it says to push the brake to start the car but it doesn’t always start up. Sometimes it requires opening the door. Sometimes the collision mitigation system turns off after as well. And the entertainment display turns off or says “No Audio”

The Foward Looking Camera is failing and causing all the ADAS not to work and has all the lights on the dash. The code comes back as U3000-49 which is a multi purpose camera failure.

2018 Power Tailgate Failure from Body Leak Tailgate stopped working. I read so many owners have the same problem.

My right sliding door stalls intermittently. It won’t open or close. My dashboard will read right sliding door problem. This has happened intermittently over the past 6-8 months.

Today I was driving on my road and there are small hills. I was going around a curve i take every single morning and my car kicks really hard as if it is having trouble changing gears. sometimes it makes loud noise. This has been happening for years now and Honda is not addressing it. There is an issue with the 9 speed transmission in these vehicles that have been dealing with recalls. This makes driving scary and my kids are now scared to drive to school in my vehicle. It needs to be addressed as my family is now noticing how much honda has put us in danger knowing these recalls were not really taken seriously.

My 2018 Honda Odyssey experienced a heavy snowfall in January 2025. The control panel displayed an alarm, Power Tailgate Problem , and the trunk door could not be opened. I asked a professional who pointed out that it is usually due to water intrusion into the control unit located on the rear driver's side body panel, which causes the tailgate to fail to open, close normally, or even open accidentally. They believe that this is a manufacturing defect caused by the manufacturer and there is a safety hazard.

My 2018 Honda odyssey EX-L had a power tailgate failure. It looks like the controls module has experienced water damage from a water leak. An independent service center has confirmed the issue. There was no warning before it happened and it is a safety issue as my tail gate cannot Be securely closed. This water leak looks to be manufacturer error.

Water intrusion is causing failure of my liftgate module. The maintenance shop has identified this as the issue. After doing some research, this appears to no be a one time situation as i have read of several other owners experiencing the same issue. Lift gate is not opening and potential of liftgate opening uncommand due to module failure.

My back windshield popped and shattered without anything hitting it. Driving on a smooth road at 45 mph and all of a sudden back windshield popped and shattered. Was driving with my wife and two kids. All went to a sudden sock. That was a very bad and scary experience along with the out-of-pocket expense to replace the windshield.

Passenger side sliding door consistently failing to close. Each time problem occurred the showroom needed to reset the door. While traveling if this slide door open it is closing back. Until reach showroom I have to drive van when door opens and it beeping. It happened couple of times therefore I am afraid to open the door. Thank you!

When pressing the accelerator from a stopped position, sometimes there is a need to let off the accelerator and then press it again. There are times when I do this sequence of events and the car doesn’t accelerate but almost seems to stall. Pressing the accelerator does not increase the speed. To remedy, I have been waiting a few seconds before repressing the accelerator to give the van time to shift or whatever it needs to do not to “stall”. This evening particularly, I was turning right on red so I accelerated and then I noticed that the cars on the street I was turning into had started to go so I let off the accelerator. Unfortunately I noticed that I was too far into the intersection and had no choice but to keep accelerating but my van stalled and wouldn’t accelerate when I pressed on the gas for a few seconds. It eventually “caught up” and accelerated but I ended up spinning my tires and “peeled out”.

My power tailgate stopped working after heavy rain. Based on online research this is a known issue due to faulty roof sealing and water infiltration, leading to tailgate module corrosion. The issue was confirmed by dealership diagnostics. They confirmed module corrosion and water infiltration. Offering replacement and resealing at $1069. https://www.carscoops.com/2024/11/honda-being-sued-because-some-odysseys-may-have-a-leaky-tailgate-than-can-open-at-anytime/

My trunk was working anymore. I could not even open it manually. I had a shop that only works on Acura's and Honda's look at it. The control module for the trunk was wet and fried. I dont understand why it was wet in the first place since it was in seal box. This should be a recall on it. Please see attach pictures. I paid $669 to have them replaced it.

Hello, my name is [XXX] . I have a 2018 Honda Odyssey that I bought brand new 6 years ago from Open Road Honda in Edison, New Jersey. We received a notification of the tailgate malfunctioning out of the blue yesterday evening. It was raining the whole day yesterday. Upon checking the internet, we found this to be an issue faced by multiple Honda Odyssey owners and a dedicated thread discussing this in the Honda Odyssey Forum. Link to it is here: [XXX] After doing a little bit more research, we found a potential problem to be a malfunction due to water going into power tailgate module and this could be caused by some welding defects from Honda. We decided to remove the fusebox cover in the back left of the car (driver side) and found that there was water inside. We have sent the car to our mechanic to resolve the issue. Please see pictures and video attached for your review. This also has the VIN number for our car. But, since this seems to be a manufacturing defect and it is going to cost a lot to fix, we would appreciate Honda taking action on this. We would like to take this to a dealership for issue resolution with Honda facilitating and paying for the repairs since it is a manufacturing defect. Please advise us on next steps. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After rain, the next day, I get error tailgate problem on my dashboard. I can no longer open it using my remote or from the front panel of my van. I saw many complaints of similar issue out there. This should have been a recall due to manufacture failure.

When the vehicle is at a full stop and you press the gas, there is a stall in the vehicle acceleration. I’m unsure if this is a transmission or engine issue however it has done this since the date of purchase. I have contacted a Honda dealer who stated “this is a known problem but there is no solution for it”. This is a very large safety concern as the delay can easily cause a crash.. I have to plan for plenty of space prior to turning just in as it stalls while attempting to drive

I was driving the vehicle as normal and stopped at a Red Traffic Light. I attempted to drive when the light changed to green. The car stuttered, the dashboard lights flashed and the car shut down. - Multiple attempts to re-start failed. No prior warning lights etc. Car just return from Dealer to address Recall Issues etc. Dealer made comments on Brake Maintenance etc which was then serviced. No Mention of Auto Stop/Start issues. - FULL failure: No brake, no steering, no radio, dashboard went blank. No lights. - FAILURE OF HAZARD LIGHTS TO WORK. - This is a SHUT down in the middle of a busy street with 2 kids in the car. NO Hazard lights working. - Mulitple near accidents from incoming traffic. No lights working??? -Spoke to mechanic over the phone. He thought it was NOT likely the battery and I needed to get a tow truck. -Tow truck not available for several hours. - Mechanic was able to send someone to me. He worked on it and eventually got it to start. - Immediately took it to the Mechanic Shop. They Tested the Battery, alternator, starter and connections. Stated No Problem detected. - Mechanic thought it could be related to the computer/Auto Stop/Start system and suggested I get it checked at the Dealership. -Spoke to the Dealership the following day and base on the description of events they also mention the Auto Stop/Start system???? -This seems to be a problem they are aware of but????? The Dealership recognize this problem base on the conversation???? It is thus well known???? - Car left at Dealership - This is EXTEMELY DANGEROUS. The car Shuts Down/Freezes in the middle of Traffic. - NO HAZARD LIGHTS WORKING?????? - This is an Accident/Deaths waiting to happen. - Why is the computer even controlling the HAZARD lights. That is a HORRENDOUS Design Error. Hazard Lights should be HARD WIRED to switch.

SUNROOF EXPLODED - glass was contained by cover but I had to hold cover shut until I got to dealer - insurance inspected the damage - no warning before it happened

As I was driving down the interstate in my 2018 Honda Odyssey, clear of other vehicles or debris, I heard a loud bang and saw glass slide off the back of my car. I could instantly hear the air in the moonroof as if it was open. Fortunately, I had the cloth/hard cover closed so no glass got in my car or on me. For obvious reasons this is extremely dangerous and puts many people in the car and outside the car at risk. The shock of the exploding sunroof while driving on the interstate is not safe but if the cover wasn't closed, it would have covered me and my children in glass shards. One week ago, January 27, 2023, I had my a few recalls repaired on my van. One being, "Safety Recall Campaign: Replace Harness Clips and Moon Roof S/B 20-012".

The automatic tail gate hatch closes when its fully open. It will close while under it and bumps your head if you're not careful. I have bumped my head a few times. Nothing serious enough to see a doctor but it happens 95% of the time the gate is opened. I reported this to Honda dealer where I purchased the vehicle over two years ago before COVID but it doesn't seem to concern them.

The component that is giving me issues is the power liftgate. As I have been driving down the road, it has unlocked and opened even at a stoplight. And would go up and down up and down until finally it runs the battery completely dead. I have taken it to Honda. They did not know what’s causing it. I am taking it now to another service dealer. to see if he can fix it. I’m in hopes that he can do something. But upon reviewing other complaints online, this has been an issue for other people. That could cause a lot of safety issues for anyone around the vehicle or driving the vehicle.
