general problems of the 2018 Honda Odyssey - part 2

Improper seal on exterior driver side roof near trunk lift gate. Allows water inside during heavy rain or when going through a car wash and the water damages the control module for the power tailgate. Damage to the control module cuts off any use of the tailgate, even manually. This is a $900+ repair due to a manufacturer error.

Front facing camera malfunctioning, and it is available for inspection upon request. This malfunction causing 5 different warning lights to show up on dashboard. Including 1. ) auto high beam problem, lane keeping assist problem, collision mitigation system problem, adaptive cruise control problem, road departure mitigation problem. The issue has been confirmed by the dealer. There were no warning lights prior to the random malfunction. I have not had wind shield replaced (which I have read could mean a calibration of the camera issue), nor has there been any accidents taken place. My safety is at risk as I am unable to use these features while driving unless the front camera is replaced.

The circuit board for the module that controls the power lift gate is damaged from water. Water seeps in the roof rail and wets the panel causing the the power tailgate to lock shut and unable to be opened.

Multiple warnings occurred simultaneously for the "brake system" intermittent. I have the same issue per [xxx] for my Honda Odyssey 2018 elite. I can see the same problem by a lot of people. I told Honda and paid them $220 diagnosis fees and they ended up asked me to change the whole camera that cost 4k. This obviously defect issue from Honda. Looks like known issue for this. Can this escalate back to Honda? for example [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Went to leave my house at 8pm and the car was malfunctioning. Blind spot problem, parking sensor problem, road departure mitigation system problem, auto engine idle stop problem . Lights flickering on and off, console lights not working, can’t control heating speed. Light would not stay on as I was driving . I have a couple videos of the malfunction.

During rain and snow storms I will get warning lights that the power tailgate isn’t working. Last year when I took it into the dealer they said the tailgate would open and close randomly and there was water in the rear fuse box. I thought I fixed the issue by replacing all the wires from the rear all the way to the front. They fixed my tailgate and did water testing to make sure no water was coming in through the tailgate and all was great. Fast forward to this year and the middle of February we had an all day snow and rain storm and I start having these same warning lights along with a couple others. By the end of the day the tailgate completely stops working. I take it back to the shop that had originally fixed it and water is getting in. Not from the tailgate but through some unknown opening. The fuse board is completely corroded and we have to replace it again. They could not determine where the water is coming in from. I do not want to be driving down the road and have my tailgate randomly open and have items fall on the road causing injury to someone. Nor do I want to have to pay $1000 to fix the circuit board every time it rains or snows. I live in utah it happens frequently.

My car has had all recommended service completed by the dealership since I purchased my Honda Odyssey in 2018. On 2/18/25, my power liftgate started malfunctioning. An error message beeps inside my car 4 times, every 4 seconds and cannot be manually turned off. I took the car to the dealership and was quoted $7500 to make the repair. My car only has 90,000 miles on it and has passed all of my previous service inspections. Supposedly, water is getting into the rear control module. I have never had water in my car so this is clearly a manufacturer's defect that is allowing water to seep into the rear control module.

The power tailgate has a failure. I took my minivan to a local mechanic who said the motor has failed. I tried to see if I could do the repair myself and came across a number of forums and youtube videos that detail this is a known, reoccurring issue.

The tailgate control module (tcm) was infiltrated with water due to a crack in the seam on the rear driver side panel. This caused the tailgate to be unusable and no longer latch as a result of no power to the tailgate latch. The tcm (part #: 74970-thr-a12) had to be replaced as well as all seams needed to be sealed.

The seam seals on the rear driver's quarter panel of the vehicle are faulty and allowed water to flow into the cabin of the vehicle. The resulting damage was loss of function to the rear power lift gate, front seats, remote start and other key fob functions, as well as a dead battery(assumedly due to arcing on wet circuitry). The damage rendered the lift gate inoperable as I it initially closed but came open during operation. We continued to receive a power lift gae problem on the "heads up display" but the power gate would not open or close, electrically or manually. After a few days the gate opened but would not close, rendering the vehicle unsafe to operate. Furthermore, the battery was dead and would not start. Had this incicdent not occurred in our driveway we could have been susceptible to being stranded in sub-freezing temperatures with kids. The vehicle was taken to a dealer and they confirmed a roof leak was a cause of the water incursion. The power lift gate module and floor harness were damaged causing failures to lift gate operation and other electronics. It will cost $7000 to have it repaired at the local Honda dealer. Pending completion of repairs and paperwork for submission.

Tailgate warning beeps. Tailgare will not open or close. Dashboard lites flash. Vehicle will not start ! cannot start or move vehicle!.

Power tailgate malfunctions. Random errors showing on dashboard and randomly attempts to open on its own.

Did not control engine up and down fuel nt work.

Infortainment center shuts down and loses connection. Which means there is no communication with the backup camera or navigation. Popping noises from the front speakers start static and pop then the screen states connection lost then goes black. Turns back on in about 5-10 minutes depending. Also the lighting for the buttons around the center are not working as well. Idk if this is related or is an overload that the system cannot keep up.

Unknown but many Honda Odyssey owners are reporting the same issue which most likely caused by defective multipurpose camera at the front windshield. This create alerts and deactivates safety features: adaptive cruise control, emergency braking, lane keep assist, collision mitigation, auto-high beam, road departure mitigation, and brake system.

Driving vehicle on the road, the suite of driver assistance system suddenly failed including lkas, front collision warning system, adaptive cruise control, lane departure as well as brake system light. I took the car to the dealership which indicated the front camera had catastrophically failed. This issue seems to be a recurring issue in all models of Odyssey minivans. The issue is well documented in online forums. It should be a safety recall from Honda compared to other recalls on same vehicle. Dealer quoted me $2000 to fix this! Honda - fix this and issue a recall before there is a lawsuit and someone gets hurt.

Multiple dash lights warnings (lkas, forward collision, lane departure, etc. ) came up. Brought it to the dealership and was told that this is an electrical camera issue that is overheating, and there is no preventative or ways to keep it from happening. It would cost an upward of $2000 to fix it. This should be part of the recall since it seems like it’s happened quite frequently with the other Honda Odyssey.

Lane keep assist, road mitigation, auto hi beam, adaptive cruise control, collision avoidance, road departure all errors and no longer work. New windshield wuth calibration August 2024, new battery 10/28/24. Issue started 10/25/24. A little over 90,000 miles on vehicle. Started vehicle in parking lot and all warnings came on. After new battery, warnings cine on and off at random.

Just purchased a 2018 Honda Odyssey elite and as soon as I turned on the sound to listen to music for carplay /bluetooth/stereo all methods of sound it started making loud crackling sounds and starts going intermittent with sound cutting out. I lowered the volume and crackling still loud like little tiny rocks hitting window sound. I seen there's a recall with the same issue for other vehicles but when I input my VIN there's no recalls. I am having the same issue and feel like my VIN /vehicle type should be on recall as well.

What component or system failed or malfunctioned, and is it available for inspection upon request? tailgate stopped opening and then opened unexpectantly; vehicle is available for inspection how was your safety or the safety of others put at risk? tailgate opened while driving has the problem been reproduced or confirmed by a dealer or independent service center? no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? warning alert that tailgate had failed and warning went away approximately 12 hours bofore tailgate unexpectantly opened.

Failure of the front windshield mounted monocular camera from overheating causes all advanced driver assistance systems to shut down such as automatic emergency braking, adaptive cruise control, lane assist, etc. This is a very common occurrence in not just the Honda Odyssey, but other Honda models as well. A new part can be anywhere from one to two thousand requiring dealer calibration. The heat from the sun, the location of the monocular camera and possible contribution from replaced non-oem windshields may contribute to the overheating. With all safety devices disabled, the vehicle becomes unsafe to operate requiring immediate attention and dealer only service since a new device requires calibration.

All of our sensor controlled equipment is not working. Lkas, acc, forward collision, auto brights, etc.

The right sliding door has had intermittent malfunction for years. Often, the door will not work with an automatic function and must be pulled open or closed manually which is nearly impossible to accomplish. Most often the right sliding door malfunction notification appears when driving at highway speeds which is extremely unsafe. This has been inspected by the dealership and no fix or resolution was provided. Recently, all of the adas systems are intermittently malfunctioning. They work about 1 out of every 5 times the vehicle turns on lkas, auto braking, adaptive cruise control, are all affected. Within the last week the internal camera system has been failing, audio stops working, and most importantly the rear hatch has been closing on its own while I am standing underneath it loading the trunk. This is also very unsafe, it atleast beeps to warn that it is closing but I sometimes barely have time to get out of the way. Yesterday while driving in the highway, two warnings appeared simultaneously for “transmission system problem” and “blind spot notification system error”. The vehicle started again without the transmission system or blind spot error but I am very concerned about the degrading electrical system issues that I have been experiencing with this family oriented vehicle model.

There is a water leak in the body of the van (where the top and side are welded together). The water has caused damage to the electrical panel that controls the back door/liftgate. The water damage is also shorting out and causing electrical damage and the battery to die very often. I have noticed many complaints about this. I believe this should be a recall because it is a flaw in the making of the vehicle and nothing I could have done to prevent it.

Initial issue was that the power tailgate would not open at all. Took the vehicle to the dealership where they replaced the latch and the control unit that was completely fried. When I asked what could cause that, they said they didn't know. I already suspected water. Two days after picking the vehicle up from the dealership, the tailgate is now constantly opening and closing on its own. The only way to stop it is to turn off the vehicle and lock it. I searched online and found multiple posts from people with the exact same problem and almost all of them say it was water getting into the control unit. This poses an obvious safety concern since it could close on one of my kids. They would not be strong enough to stop it. I have reported the issue to Honda hq and have recommended that the other people with the issue do the same.

The tailgate malfunctions and the car does not register the tailgate as closed even if it is closed. The power tailgate ceases to be operational and the locks do not work. The cause is a defect in a seam which allows rain water to reach the control unit for the tailgate. This was confirmed after an inspection at an official Honda dealer. This is a safety issue because it renders the car inoperable. The “tailgate open” warning signs and sounds flash. There is currently a Honda “engineering request for investigation” released. It can be accessed at the following link: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Crack in body seam above driver and passenger side of the tailgate and underneath the roof rail cover caused water leakage. This resulted in a short of the power tailgate control module which draws down my battery and causes unexpected trunk closing during normal use. Family members have been hit in the head by the trunk due to the unexpected automatic emergency closing.

Tailgate malfunction due to water seeping through tailgate resulting in tailgate module to stop working.

Vehicle stalls when pulling out into traffic! terrifying with my 6 kids and I'm immediately getting rid of this vehicle. Tried to have the fuel pump (current recall) replaced but Honda dealership has the vehicle for 6 days! and still didn't have the part in. Upon dropping the vehicle off the tailgate lift would not work properly. This van is a load of garbage since they started using so many modules to control it! extremely disappointed in Honda. They know all of these faulty parts and don't care enough to fix them for the safety of the consumer. Absolutely horrifying the direction of the automobile industry.

The lane keep assist function via the monocam behind the windshield has failed causing an alert to show up a few minutes into driving that none of the systems related to it are functional. This appears to be a widespread problem amongst owners of the 2018 Odyssey. Additionally, Honda service centers are acting like this is a surprise to them but searching online will results many individuals with the same issue and then being charged 1300-2000 to fix it. Since the features are all safety related I assumed this was where I should submit this. Please let me know if this is not the case. See the Honday Odyssey forums for many people noting this problem. . . [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

During my recent recall repair by ed morse Honda in riviera beach, FL, I was advised that the rear tailgate sensor was reported as "wet". I do the maintenance myself, so I passed on a repair at that time by the dealer. Today, I researched what might have failed both online and with my alldatadiy subscription, and accessed the part. Indeed, the liftgate control module was molded and need of repair/ replace. However, I have grandchildren now, and during the removal - realized that in a water accident or other hazard where power is lost, there is no way for rear passengers to exit the van by the rear tailgate. There is no readily accessible latch or pull to open the tailgate from the inside, and no key nor latch available from the outside for outside assistance. Additionally, if a child is in need of exiting the rear tailgate, there is no child safety pull to allow them to exit. During my research on how to repair the vehicle, I saw that this is an ongoing issue for this model of Honda. I like my 2018 Honda Odyssey very much, it is my second Odyssey (the first was totaled in a t-bone accident, where both wife and daughter walked away), but I believe a recall is needed for the water issue affecting the tailgate control board for the short term, and safety mechanisms added for the long term. Note: I have images, but the web site is not allowing uploads of any . Jpg nor . Pdf's at this time.

Rear tailgate is inoperable because of water damage. The rear driver side seatbelt is wet, the floor of the trunk is wet, the water damaged the control module for the rear tailgate, it does not open.

Power tailgate issue continues to happen. The module is somehow getting water damage and shorting out. This is the second time in a year that I have to replace the module. I can’t even manually open my trunk without having to climb through the car and undo the latch from the inside.

When audio system is turned on, a very loud crackling sound occurs, and will continue after audio is turned off. Sirius xm works most of the time (with crackling sound). However, when the regular radio is turned on the audio will work for just a minute (with crackling sound), and then it will suddenly stop working and a message pops up on the display that says "audio connection lost". This also happens when a phone's bluetooth audio is connected to the car. It triggers the audio system to suddenly fail. There has been other electrical issue with the rear lift-gate suddenly closing, with no way to stop it. It almost pinned my daughter and I on separate occasions. I'm not sure if this electrical issue is related to the audio issue, but as with any electrical issue I worry about the possibility of an electrical fire.

The automatic tail gate stopped working. When I went to replace the tailgate control module I found out that it was damaged due to water that leaked into the rear driver side cabin area. After doing some research to figure out the problem, I found that there where many others that have had the same problems on the same year, make and model as mine.
