2018 Honda Odyssey Complaint Log

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.

See attached document for complaint.

The engine failed without prior indication. The dealer says the engine is destroyed and needs to be replaced. Once the engine stopped working the vehicle would not go into neutral and was immovable preventing the vehicle from being moved to a safe location. The dash had a message that said the engine must be running to shift to neutral but the engine was blown. The owners manual has no solution to put the vehicle in neutral with an inoperable engine.

Over a year ago, my vehicles engine began ticking. On 12/14/2024, while driving the vehicle, it developed a rod knock, went into a limp mode and was towed back to our house. I eventually took the vehicle to Honda in Beaumont, Tx where they did an inspection of the vehicle and verbally told me it was the crankshaft, but would not provide me any documentation stating that. According to the lady at the desk, the service tech had never seen or heard of an issue like this in these vans. I was quoted almost $10,000 to replace the engine with a salvage yard engine with almost as many miles on it. I knew prior to taking it to Honda that there was a recall that did not cover my vehicle regarding this same issue. The vehicle is still parked at my house being started occasionally to keep battery charged.

The contact owns a 2018 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and confirmed that parts were not yet available. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

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/

I just had several recalls completed on my van. The issue that they couldn’t fix (which I have seen on so many message boards) my car stalls when starting from a stop. If I’m at a stop sign and press the gas nothing happens for 2-3 seconds and then it will catch and take off throwing everything in the car and the people forward. It is terrifying! I’ve had it happen with cars approaching and just been a sitting duck, thank the Lord it engaged in time. This seems to be a very prevalent issue and I don’t understand why a recall hasn’t been done before someone dies. My trunk also doesn’t work automatically anymore and they said I had a leak that would be $300 to diagnose and $500 to fix. I know ther are lawsuits for both of these issues. Recalls need to be issued.

Leakage through the top driver's side pinch weld near the rear of the vehicle has allowed water to infiltrate the power tailgate control module and render it sporadically operable. This has affected the vehicle main computer, causing unreliable operation of powered vehicle exit doors.

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.

All alert lights came on suddenly (ACC, collision mitigation, road departure, auto high beam, etc). Took the vehicle to the dealer for a diagnosis, and found out there is a faulty multipurpose camera in the front near the windshield. Upon research, this seems to be a common problem for Honda vehicles manufactured between the years 2018-2019. Total cost of repair and labor is over $2,000.

The camera projector needs to be replaced according to the Honda dealership. Too many Honda Odysseys are having similar issues. Come thing is battery replacement or vehicle is located in warmer climate states. This camera mount is too sensitive to voltage swings or warm weather which is a poor design by Honda. It is a major safety concern not being able to use key features in the Elite and Touring models such as adaptive cruise control, LKAS, and the other 5 warnings that won't go away. This needs to be resolved by Honda so that vehicle owners can get back on the road safely. The cost to replace the camera and calibration is ridiculous ($1700 - $2000). This will be the last Honda vehicle we ever buy if Honda doesn't setup and correct this issue with thousands of Odyssey vehicles. This a major issue and Honda needs to recall and correct this issue before a major lawsuit comes their way to due to this poor design.

I got in and turned on the car one afternoon and all these lights came on. No wrecks or anything has happened. Just all systems have failed. Brake System problem ACC problem Collision Mitigation Problem Lake Keep Assist Problem Auto High Beam Problem This is a HUGE safety issue as this vehicle carries my children. We will be taking it to the dealership this week but these types of issues shouldn’t be happing this quickly. We need a recall to fix this issue as many many others have had these same issues. These are safety systems that will save your life!

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!

Multipurpose front camera controlling multiple vehicle safety features had internal failure. Dealer required replacement of camera and calibration. Multiple warning lights came on dashboard to alert of issue. Faulty camera was diagnosed by Honda dealer and is with dealer currently.

Code p219b. I feel this vehicle falls into the same fuel injector issue as other 2018 Honda odyssey. Bulletin 20-100, 21-010

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.

The check engine light on my 2018 Honda Odyssey has been on since January 2024. We took it to the dealer (Music City Honda - Mt. Juliet, TN) and they claimed the 02 sensors were bad. We paid $500 to have these replaced, but the light came back on. We then received the recall for the fuel pump module. We have tried twice since May 2024 to get the part under recall replaced but have been told both times that the part is unavailable. The dealer claimed that we could bring it in but if the issue is not determined to be related to the recall, we will have the pay the diagnostic fee. Not only is my check engine light on (it says Emissions System Problem), but my car stalls while driving. This poses a significant safety risk for myself and my family, and Honda is refusing to do their part to remedy the issue at no cost.

Either the engine or something else keeps failing and i completely lose power. I got the car towed back to my house. The car starts but a lot of the time it will keep shutting down while I'm on the road. I went to the dealership twice to get it checked out and they say that they do not know what the problem is and can not guarantee that they can fix the issue.

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

Monocular camera failed, all warning shown in the dashboard.

Adaptive Cruise Control, Forward Collision Warnin, Lane Departure Warning, and Lane Keeping Assistance lights came on and won't go away. Sometime the car won't reverse when put in reverse.

Both of the manual passengers back doors will not fully close and lock.

The Monocular front window camera is malfunctioning. This front window camera controls the following safety features: -Lane Keep Assist (LKAS) -Collision Mitigation -Adaptive Cruise control -Lane Departure Mitigation -Rain sensor windshield wipes -Auto High beam -Automatic Emergency Braking In addition to compromising these safety features when the camera fails, false warnings are repeatedly provided on the dash of the Vehicle, sometimes in a singular and sometimes in a cyclic manner.

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.

Had about 4 incidences that van completely stalled while driving when coming to a stop. about a week later, was driving the van at approximately 6o mph when it completely shut down, had to pull over immediately to get off road. came to a fast stop. was thankful no other cars were behind us when it happened, feel they would have hit us as the vehicle shut down so quickly. there were no warning lamps or messages indicating any issues. My husband changes the oil/services it according to the manufacturer guidance. Was told by the local mechanic the engine is locked up, would need replaced. Called Honda to report, and since we do not service it at a Honda dealership, they would not assist.

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 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”.

Issue-1 High pressure fuel pump in the engine bay (no the fuel pump that was recalled for some VINs) failed at 88000 miles. There was a loud motorcycle exhaust kind of sound coming from the engine bay , which is more audible from inside the cabin than from the engine bay itself. Took it to service center for a 1500$ replacement. Wrote to Honda customer care , but they rejected by claim and goodwill refund saying there is not recall for this item. It is example of poor quality of Honda these days especially with this 2018 Nine speed model. Issue-2 MAJOR SAFETY ISSUE. The vehicle doesn't accelerate while moving from a complete stop or turning into a busy intersection , making us prone to big Collison from oncoming traffic. The vehicle lags for 3-5 seconds before it accelerate rapidly. This is an ongoing issue with this model which Honda ignores and is a disaster waiting to happen. NHTSA should look into this and recall all HONDA 2018 9 SPEEED ODYSSEYS to fix this issue. It is been 6 years and Honda comfortably ignoring this safety hazard especially for a vehicle meant for kids.

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 seems to appear for recent and older vans and is well documented in online forums. It should be a safety recall from Honda compared to other recalls on same vehicle.

Started my car and got all these warning lights ACC problem, Collision Mitigation Problem, Lake Keep Assist Problem, Auto High Beam Problem. From reading forums online this is a common issue for Honda Odysseys 2018-2023. The camera is faulty. This should have a recall.

The contact owns a 2018 Honda Odyssey. The contact stated while driving approximately 35 MPH, the engine made an abnormal knocking sound. The vehicle was taken to the dealer, where it was diagnosed that the timing belt had failed and needed to be replaced. The timing belt was replaced; however, the failure persisted. The dealer determined that the connecting rod bearing in the engine needed to be replaced. The dealer informed the contact that the engine needed to be taken apart to perform the repair. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 23V751000(Engine and Engine Cooling). The manufacturer was notified of the failure and informed the contact that the repair could not be covered under the recall because the VIN was not included. The failure mileage was approximately 86,470.

I was driving on the interstate at 80 mph when my engine suddenly failed. The check engine light began to flash, the car began shaking, and there was a very loud thumping from the motor. Thankfully, I was able to pull off the road to safety. Honda diagnosed the problem this morning. They said a connecting rod bearing rotted out, so the engine threw a rod. There is a recall addressing this exact issue for my model year, but my VIN was not included in the recall. Doing a quick google search, I found several other owners of 2018 odysseys in the same boat - sudden engine failure due to a thrown rod, but their VIN wasn't included in the recall. I drive my car a lot, so it has 140,000 miles on it already. This makes me think that I'm likely to be in the early wave of vehicles experiencing sudden engine failure due to an issue with the conn rod bearing. Someone else may not get so lucky and be able to pull off the interstate when their engine blows. The repair is going to cost me approximately $8,000. Once I have the invoice and other documentation available, I'll share it here. I didn't want to delay sharing this information until after the repair is done, though, because if Honda doesn't expand their recall to include more 2018 Odysseys, someone else isn't going to get as lucky as me, and injury or death are a real likelihood. (Plus, having your engine suddenly fail is just a bummer regardless.)

Upon inspection from Honda dealership, internal failure of multipurpose camera

After weathering hurricane Milton, the rear liftgate on my 2018 Honda Odyssey will not open. No apparent damage was done to the vehicle, however after starting the van, the dash stated there is a power liftgate issue. This warning was not present before. After doing some research the issue appears to be the tailgate control module, as many other people have found this to be the case. Some people have said to open the tailgate from the inside using the manual latch. However, in my case after attempting to do so, the door remains stuck. A lot of people have pointed to water intrusion as the reason for a faulty Tailgate Control Module. If I am able to open the liftgate manually I intend to replace the faulty module.

When trying to accelerate from a stop either in an intersection or from a driveway the vehicle takes a long moment before it responds... leaving my family vulnerable to cars coming from the opposite direction. I think it's the transmission but it could have to do with the fuel intake... it has been ongoing for months and months. The dealer has attempted to rectify but to not avail....very dangerous

The contact owns a 2018 Honda Odyssey. The contact stated while driving 70 MPH, the vehicle lost motive power and failed to accelerate as intended. The check engine warning light was illuminated. The vehicle was then steered over to the side of the road and restarted; however, the failure persisted. Additionally, the contact observed a knocking sound coming from the engine compartment. The vehicle was taken to the residence. The vehicle was then taken to a dealer where it was diagnosed that the control rod had fractured, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 144,000.

During the hurricane Milton evacuation my wife and our 3 children suddenly lost power on I75 North in the dark and had to pull to the side of the road with speeding cars flying by in near pitch black. we later discovered that the control rod in the engine is broken according to a Honda dealership and we would need a new engine. The dealership said it is very strange for this to happen with how well it appears to be maintained and that there was a previouse recall on the 2018 and 2019 Honda Odysseys and mine might need to be included however upon speaking with Honda they said there was nothing they could do. Dealership quoted me $9,100.00 for new engine.

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.

My 2018 Honda Odyssey van have had persistent acceleration hesitations after completed stops, especially during making left or right turns at street intersections since July 2022. This car normally hesitates for 2 to 3 seconds after accelation pedad is pressed before suddently jumps forward. Acceleration hesitation for few seconds, during making a turn, is very dangerous due to in coming cars in my opinion; as a result, we have tried to avoid using my odyssey van as much as possible due to potential accidents when making a turn with this Honda van.

Multipurpose camera failure. Warnings appeared upon failure after being parked in the shade on a moderately warm day ~80 degrees. Warnings with chimes reappear after being cleared, causing distraction while driving. Safety systems are inoperable without expensive camera replacement. Systems disabled as a result include Adaptive Cruise Control, Collision Mitigation System, Lane Keeping Assist, Road Departure Mitigation, Auto High Beam system.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly shifted to park(P), and the vehicle shut off while approaching a traffic light. The contact was able to restart the vehicle; however, the failure recurred while driving and exiting a parking lot. The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that the engine needed to be replaced. The mechanic related the failure to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.

When I turned on the ignition to drive the vehicle, multiple warning lights came on to include failure of Lane Keeping Assistance, Forward Collision Avoidance, Adaptive Cruise Control, Lane Departure Warning, and Automatic Emergency Braking. Additionally, after acknowledging these lights, the "Brake System" light remained on in the Amber color. If these safety features are not working properly, it can put the occupants of my vehicle as well as others at risk. We took the vehicle to the Honda Dealer. They ran the diagnostics and stated that the fault was "Internal Electronic Failure of Multipurpose Camera Unit/Internal Failure of Multipurpose Camera". We had to replace the Multipurpose Camera and have the new one re-calibrated.

Transmission hesitation when turning from stop. Scary when traffic is coming. Not safe and seems to be a common, known issue. https://www.odyclub.com/threads/2018-odyssey-having-1-3-second-acceleration-lag-from-stopped-or-rolling-on-9-speed-transmission.368250/ https://www.reddit.com/r/HondaOdyssey/comments/pxw7xz/2018_honda_odyssey_having_major_acceleration/ https://www.odyclub.com/threads/hesitation-on-acceleration.362860/

The front monocular camera (36160-THR-A03) completely stopped working. It is behind the rear view mirror, behind the front windshield. Errors displayed on dashboard indicating lane keep assist, forward collision warning, brake mitigation system, adaptive cruise control, and brake system lights turned on. (99% of the time). On occasion, transmission problem, blind spot detection, AND rear camera cross traffic detection (radar disabled) would also go on (3% of the time). While driving the vehicle on the freeway, the dashboard went completely BLACK for about 3-5 seconds, and I could not see my speed, fuel, odometer, and everything else. It came back on, but that really concerned me. I immediately opened a ticket with Honda Corporate. (Repair Diagnosis Request: 14552995). The root cause was not identified. However, some speculate a failing battery (low voltage) can trigger it. In my case, I replaced the battery first when the symptoms first started, but the issue did not resolve even after driving it 500+ miles. The oddest symptom is something I could not explain. Every Saturday (like clockwork because kids soccer practice), between 12pm-1pm local time (Eastern for me), the issue would go away completely and the camera (and all assistive features) would work completely normal. As soon as I power off/on the vehicle, the issue came back immediately… until the next Saturday. This happened 3 times, 3 weeks in a row. Makes me think there’s a software/firmware glitch. Honda did a goodwill with me and paid 50% of parts and labor. Honda (dealership) confirmed it was a part failure, and replaced the part and all issues went away. Given the front camera issue also affected the rear camera on occasion (cross traffic radar failure), and that part was already recalled, my opinion that when this part fails, it has greater implication to other safety features/electrical system. Due to this also being cost prohibitive, I suspect many will opt to not to fix it.

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.

Vehicle started to display ACC PROBLEM, LKAS PROBLEM, TRNSMISSION SYSTEM PROBLEM, COLLISION MITIGATION SYSTEM PROBLEM, ROAD DEPARTURE MITIGATION SYSTEM PROBLEM, AUTO LIGHTS PROBLEM and BLIND SPOT INFO SYSTEM PROBLEM recently around September 19,2024 and disabled all the safety features mentioned on the vehicle while it is in motion. This is a huge safety issue and could cause severe problem for many drivers and passengers in case of serious accidents which could be avoided if those systems are functioning properly. Upon researching the issue, this is very common problem for many of similar vehicles and it seems to be related to the monocular camera on the windshield. I strongly urge for quick investigation on this matter and have Honda Motors to do a recall for replacing faulty camera as it could impact many lives.

Diagnostic is U3000-49: "Multipurpose camera unit/millimeter wave radar internal electronic failure. Multipurpose camera internal failure. Camera is overheating and hot to the touch." Honda is saying this is separate from the recall already issued on the camera and will be a $2K repair. Multiple other owners of other 2018 Honda Odysseys reporting same failure. Van running fine, then all of a sudden warning panel lit up with the following warning messages: Adaptive Cruise Control problem Lane Keeping Assist problem Collision Mitigation System Problem Road Departure Mitigations System problem Auto High-Beam Problem Local reputable auto repair shop said it is not safe to drive due to the extremely high temperature of the camera unit.

The contact owns a 2018 Honda Odyssey. The contact stated while driving 70 MPH, the engine seized. The check engine warning light was illuminated. The contact stated that the failure was related to NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling). The vehicle was towed to an independent mechanic and diagnosed with engine failure. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 93,000.

All of the safety features stop working intermittently on my van. The warning lights do all come on. Independent mechanic says the multipurpose camera unit has stopped working. Safety features that I thought I had are not available
