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
2018 Honda Odyssey electrical complaints
Page 5 of 10: complaints 101 to 130 of 265, newest first, as owners wrote them.
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.
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.
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.
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.
All of our sensor controlled equipment is not working. LKAS, ACC, Forward collision, auto brights, etc.
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.

The contact owns a 2018 Honda Odyssey. The contact stated that while the vehicle was parked, the rear drivers side sliding door failed to latch securely. The contact stated that when the driver’s side sliding door was closing, the contact heard a whining sound. In addition, the instrument cluster displayed a black screen. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The dealer was made aware of the failure; however, the contact was informed that the repair was not covered under warranty. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the repair was not covered under warranty. The failure mileage was approximately 141,565.
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.
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.
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.
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.
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.

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.
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
There is water leaking through the seams of my Van from where it wasn't welded and sealed properly, My tailgate opened on the highway today while I had my 7 kids in the vehicle while it was pouring down rain. I could not get my tailgate to stay closed and keep getting a power tailgate problem on my dashboard. My tailgate will no longer stay latched it automatically opens on its own and refuses to stay shut. I looked at the control module and it was completely soaked in water and can see the water leaking from the top of my vehicle in between the exterior frame and the interior frame. There are holes in the welding. They're quoting me almost $1000 to fix the mistake they made while manufacturing the vehicle. I currently have a bungie chord keeping my tailgate shut but it continously beeps from where it's trying to open automatically. Definitely the scariest day of my life today. This needs to be dealt with ASAP. Today could have been much worse than it was. Honda needs to be held accountable before someone dies over this. There is no reason why my tailgate should have automatically opened on the highway doing 65mph with my 7 children in the car.
power tailgate control module fail due to water a leak in rear driver side area.
It is available for inspection on request. Lost blindspot info, lost use of turn indicators, rear door hatch malfunction, several warnings flash up while driving. I was in a busy area and didn't have a way to signal my movements, screen flashing warnings was terrifying, the van felt like it might turn off at any moment. Before the most recent incident, we had brought the van to Honda dealer for repair, for similar issues that occured at start-up, they found water in the power control unit in rear left area of van that caused corrosion and short-circuit. No body damage or alterations to vehicle. Replaced unit and after rainy weather problems recurred at start up and power down, then while driving, they tested the battery and it was almost dead (the battery was only 1 month old) replaced battery. Problems recurred and water found again. significant leak suspected but not found yet as the service department won't evaluate the seals, and told us it's a body-shop task. summary: intermittent left-side passenger door and rear hatch door malfunction, blind spot system warnings/loss, loss of turn indication, brake system warnings, other system warnings, difficulty starting the car and turning the car off, brand new battery drained while the car was parked and turned off. This manufacturing defect should be addressed by Honda, seals should not fail when exposed to regular conditions. Water should not enter the vehicle and short out an important component leading to several malfunctions that could cause loss of important systems and rear-door latch while driving.
Water leaks into tailgate control module causing tailgate not to work. Replaced module, problem came back after 3 weeks. This is a common issue for the current generation Odyssey.
Water getting into rear liftgate control module. Had to replace seal and module.
Right Power door will not open or close with buttons or key fob. Must open/close manually. The doors are too hard to open manually for smaller children and even some adults making it a safety concern in case of emergency. This started intermittently a year ago and is now a constant. Tailgate has been opening and closing on its own, even when locked while parked as well as when the idle stop is activated while in drive. This is a concern that someone can get in the vehicle when unattended. It also shuts (and didn't stop) when someone was standing in the opening while removing something when it occurred. This started about a month ago. I was told to take it to a dealer and pay them to diagnose it. The dealers have a wait list and it's also not in my budget. These are real concerns and I feel Honda isn't taking ownership of the dangers.
Our 2018 Honda Odyssey has the defect described in this recall: [XXX] However, the VIN search says that it is not eligible. This defect causes all of the vehicle's electronic safety systems to malfunction. Occasionally it will not start at all.

A water leak above the tailgate control module flooded it to the point that it operated erratically and would raise and lower the tailgate randomly or not work at all. I plan on replacing the module myself but will retain the old one. Anytime the entry or exit points on a vehicle open randomly cannot be a safe condition. The dealer charges $130 for any inspection or diagnostic so no I am not paying them to tell me something is broken. The vehicle currently is showing a "Power Tailgate Problem" and a yellow box with "TAILGATE" in it on the dash display and is currently unresponsive to any input that would operate it: remote, tailgate buttons, and driver button. The power locking system is still operable. The Odyessy forums clearly describe multiple occurrences of this failure and the culprit is a water leak in rear window or rear section of roof trim strip on the drivers side. My module did have water in it when I opened the plastic case it is contained in. Cleaning and drying it restored operation for about 3 days. Thanks for your help!
Our Tailgate is having an issue that triggered a safety issue with my wife driving on a highway then 3 lights popped up and car entered a limp mode. transmission issue, emissions issue, tailgate issue since then car is behaving normally but the tailgate latch is opening when we start the van and not working from fob (unlock) or exterior tailgate button. I have read other owners having an issue where the tailgate control module is getting submerged by water causing the unit to short and cause these issues. A car entering limp mode on the highway poses a threat to our family and others, I hope to see a solution in the near future.
There is an electrical drain causing the battery to drain to the point where it will not start. Alternator was replaced, then the issue persisted. Most recent problem include the power tailgate opening on its own. Rear power tailgate issue. The rear tailgate will attempt to open while driving, but the warning sound chimes and alerts to the problem. If the vehicle is left unlocked the tailgate will open itself. The power tailgate button in the driver seat does not work. The close button on the bottom of the door is illuminated (has power) but will not close the door. The soft rubber button above the license plate will engage the motor to lift the tailgate, but not to close it. Others have filed complaints about a water leak impacting the rear control board and causing it to fail. Leak may be from the fin on the roof or related to the cracking and rotting seal on the bottom of the rear windshield.
Rear tail gate will not open even manually due to water getting inside of control module due to faulty design which causes water to go into the module and fry it would open and close randomly when it would rain now it has stopped working all together no indicator on dash anymore I guess this last rain finished it off terrible design very disappointing with Honda this is a major issue that needs to be fixed
