2018 Honda Odyssey Problems

The front camera has failed so all of my forward driving safety features no longer work such as lane keep assist, adaptive cruise control and collision mitigation. Every time I turn on the engine I have multiple warning lights that appear every time that have to manually acknowledge to clear them from my dashboard.

Multiple warning lights on. Dealership told me it was code U3000-49 Multipurpose Camera mutimimillmeter wave radar internal electronic failure

1. Component failed: The low-pressure fuel pump failed. The vehicle is currently sitting at my residence and is available for inspection upon request.2. Safety risk: The vehicle stalled completely while driving, causing an immediate loss of propulsion on a public road, creating a severe collision risk.3. Confirmation: The problem has been pulled and confirmed by an independent service center (AutoZone diagnostic scan tool), which pulled a code to replace the fuel pump.4. Inspection: The component has not yet been inspected by the manufacturer, police, or insurance representatives, as the manufacturer is currently refusing to authorize an inspection due to a salvage title.5. Warning lamps/Symptoms: Immediately prior to the stall, a complete cascade of warning lights appeared on the dashboard simultaneously, and the vehicle sputtered aggressively upon attempting to crank and restart.Assessment: This is the identical, textbook physical failure condition of NHTSA Campaign 23V-858 regarding defective factory-installed Denso fuel pumps in 2018 Honda Odysseys. American Honda Corporate is using an automated salvage title database filter as a pretext to deny mandatory federal safety recall remedies on a vehicle with zero structural fuel system damage.

All systems relating to the forward facing camera have failed.

The Fuel Injectors are failing which is causing a safety concern with regards to moving the vehicle. There was a warranty extension on these items that does not go far enough to remedy the issue. The components have been inspected and confirmed by the Burns Honda Dealership in Marlton, NJ. Because the vehicle does not consistently accelerate, it is a safety risk.

crankshaft/rod bearing defect that is causing an audible knocking noise in the engine and located metal shavings in the oil.

2018 Honda Odyssey EX-L, The vehicle consistently has a significant delay in acceleration. This is especially noticeable when starting from a stop or low speed and attempting to make a left turn across traffic. The accelerator pedal is pressed, but the vehicle sometimes provides little or no acceleration for 1 to 2 seconds. The vehicle will then begin accelerating, sometimes abruptly. This has created a safety concern because the vehicle can begin entering an intersection but fail to accelerate as expected, leaving it exposed to approaching traffic. The problem has occurs regularly and has been noticeable for an extended period. There are no intentional actions by the driver that would account for the delayed response. I am aware of two other Honda odysseys doing the exact same thing. One being my neighbor who brought it up themselves and another, an individual at work. My neighbor has the same year and model. The other I am unsure about. This seems to be a consistent and likely widespread issue. The vehicle is a 2018 Honda Odyssey EX-L equipped with the 9-speed automatic transmission. I will be scheduling the vehicle with a Honda dealership and ask the dealership to diagnose this acceleration-delay problem.

My vehicle intermittently shifts from normal automatic Drive (D) into S mode without any intentional driver input. I do not touch or activate the steering-wheel paddle shifter when this occurs. Searching on reddit and other forums I see many other drivers have the same issue. The problem appears to happen primarily after coming to a complete stop, such as at a traffic light or stop sign. When I then press the accelerator to proceed, the vehicle may have very little acceleration because it has unexpectedly entered S mode. This has occurred while I was attempting to turn or proceed into traffic and has nearly caused an accident on multiple occasions. The issue is intermittent and cannot be reproduced on demand. However, it has happened multiple times under similar circumstances. I am certain I did not intentionally activate the paddle shifter. I am concerned this may be a safety defect involving the electronic shift control, paddle shifter, transmission controls, sensors, or related software. An unexpected change in transmission mode immediately after stopping can create a dangerous situation because the driver expects normal automatic operation and acceleration when entering an intersection or traffic. I am requesting that NHTSA document this complaint and investigate whether this is a safety-related defect that may affect other vehicles.

Car takes longer to start, difficult to accelerate and stalls. Shaking hard when accelerating at certain speed. There is a p0087 code when autozone scanned it.

Rear sliding door failure, doors wouldn't latch properly resulting in opening when driving down the road. Took to dealership for repair. Paid $1633.78 they replaced rear latches 3/31/2026. Rear latches failed to open resulting in one Rear door cable breaking and one that will not open at all 9/1/2026. Neither door opens at this point.

Creaking from drivers side footwell. Pinch weld has to be oiled and greased. Vehicle has 108k miles. Front suspension entirely replaced, and the noise boiled down to the floor flexing and metal pinch welds moving and creaking. This is a common issue apparently in the Honda community.we now have to spray the pinch welds every week keep the noise down. Poor build quality.

My Odyssey randomly began displaying all of the ADAS warning messages: The Brake System indicator light comes on, Forward Collision Warning, Lane Departure Warning, Lane-Keeping Assist, Auto High Beam System error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire ADAS system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. Therefore, I haven't taken it to the dealership but I have discussed the issue with them. They agree that the camera is getting too hot and failing, which is causing the errors and of course all of those safety features fail simultaneously.

On 7/28/26, my 2018 Honda Odyssey began displaying the following warning lights and system messages on the dash: •Adaptive Cruise Control (ACC) system error •Lane Keeping Assist System (LKAS) error •Auto High Beam system error •Collision Mitigation Braking System / forward collision error These errors were present before I replaced the 12V battery. I had the battery tested at that time and it failed a load test, so I replaced it, expecting the ADAS-related errors to resolve. After the battery replacement, the original errors remained, and additional warning lights appeared, including a transmission system problem indicator and a brake system warning light. I disconnected the negative battery terminal for approximately 10 minutes in an attempt to reset the modules, then reconnected it. After reconnection and a period of idling, further warning lights appeared that had not been present immediately after the battery swap. I have not been in a collision, and there was no impact to the windshield, front bumper, or brake components at any point during this period. The vehicle’s brake pedal feel has remained normal. Because these errors were present before the battery was replaced, the battery does not appear to be the root cause, and the underlying issue affecting the ACC, LKAS, auto high beam, and collision mitigation systems remains unresolved. I have seen reports from other Honda owners describing similar cascading ADAS and system warning lights on comparable Honda models.

The contact owns a 2018 Honda Odyssey. While the contact's wife was driving at an undisclosed speed, the vehicle drove over a pothole and the driver's- and passenger's-side curtain airbags deployed. The air bags deployment frightened the contact’s wife, and the steering wheel was jerked, and the vehicle crashed into the concrete median. The contact stated that the front driver's side tire was flat. The contact removed the deployed side curtain air bags and replaced the driver's side front wheel. The vehicle was inspected by the insurance company. The vehicle was deemed a total loss. The contact received notification of NHTSA Campaign Number: 26V227000 (Air Bags). The contact stated that the recall notification was received the day after the failure had occurred. The manufacturer was contacted by phone, and a case was filed. The contact was informed that the case was denied. The failure mileage was approximately 135,000.

COMPONENT THAT FAILED & AVAILABILITY: The vehicle's primary electrical architecture and data communications network (CAN bus) failed during a safety recall service for the SRS ECU and rearview camera. After attempting to complete the recall work, the vehicle is no longer able to start. SAFETY RISK: The manufacturer's federally mandated safety recall remedy compromised the vehicle's critical safety and control infrastructure. This rendered a previously reliable family vehicle entirely inoperable, destroying its ability to communicate, start, or turn on. It poses a systemic safety risk if the corporate recall procedure itself causes severe electronic failures in consumer vehicles. REPRODUCTION & DEALER CONFIRMATION: Yes. The failure was induced directly by Williams Honda ([XXX]) during service on Thursday, XXX. The dealership's Service Manager explicitly confirmed to me that their technicians compromised the electrical architecture while performing the SRS ECU and rearview camera recall work. The vehicle has remained dead at their facility ever since. INSPECTION BY OTHERS: The vehicle has been actively inspected by dealership technicians in coordination with Honda Engineering headquarters. It has not been inspected by police or insurance representatives, as no crash occurred. I have requested an inspection by a Honda Corporate Field Technical Specialist (FTS). WARNING LAMPS & PRIOR SYMPTOMS:NONE. Prior to this appointment, the vehicle was in perfect electrical and mechanical working order. There were absolutely no warning lamps, messages, or symptoms of any starting or electrical problems. The vehicle had just safely completed a seven-hour road trip immediately prior to being dropped off for the recall work.

The contact owns a 2018 Honda Odyssey. The contact stated that the rear liftgate was inoperable and had to be unlocked through the emergency release in the trunk. Additionally, the contact stated that the rear window seal was significantly fractured. A message that the tailgate was inoperable was displayed accompanied by a chime that was heard inside and outside the vehicle while driving. The contact stated that the message was displayed after a rainstorm. Additionally, while the contact's son was using the seat belt, the contact became aware that the passenger’s side third-row seat belt and seat belt retractor housing attached to the roof were wet. The vehicle was taken to a dealer, where it was diagnosed and determined that the tailgate printed circuit board for the locking mechanism was corroded, and the motor had failed. The vehicle was scheduled for the repair. Additionally, the dealer referred the contact to an auto body service center to determine where the water was entering the vehicle. The failure mileage was approximately 60,000.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the passenger's side power sliding door unexpectedly opened and failed to latch. The vehicle was not diagnosed or repaired by a dealer or an independent mechanic. The contact associated the failure with NHTSA Campaign Number: 18V795000 (Latches/Locks/Linkages); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The failure mileage was approximately 195,000.

The vehicle previously received a manufacturer dash wiring recall repair. After the recall repair was completed, the vehicle began experiencing intermittent and cascading electrical and communication failures across multiple integrated systems. Affected systems include Apple CarPlay, the DVD system, in-vehicle camera systems, CabinWatch, and repeated “MOST network unavailable” error messages. These failures occur intermittently and result in multiple systems disabling simultaneously. The vehicle was inspected by a Honda dealership, which confirmed the issue involves wiring within the dash harness. The dealership stated the affected wiring is not sold or serviceable separately and that correction would require replacement of the entire dash harness, but that this portion of the harness is not included in the original recall coverage. Because these systems share common power and communication pathways, failures cascade across multiple modules. When the camera system fails, rear view camera functionality and related warnings are unavailable while backing up, reducing the driver’s ability to detect obstacles, pedestrians, or children behind the vehicle. When CabinWatch is unavailable, the driver is unable to visually monitor children seated in the rear rows while driving, which affects situational awareness and the ability to respond quickly to unsafe conditions inside the vehicle. These failures also impact driver information systems and create intermittent loss of critical visual feedback, increasing driver distraction as systems drop out unexpectedly while the vehicle is in operation. The condition began after the recall repair and appears to be related to or a continuation of the original recall defect. The vehicle remains available for inspection, and the condition has been confirmed by a manufacturer-authorized dealer.

The contact owns a 2018 Honda Odyssey. The contact stated that while his wife was dropping off their son at school, the sunroof was open, and the close button was depressed while the son’s hand was hanging out of the sunroof. The sunroof proceeded to close, and the sensors did not prevent the sunroof from continuously attempting to close. No warning lights were illuminated. The contact stated that his wife was forced to push up on the sunroof to free her son's hand, and in the process received a minor cut on her right hand, while the son sustained bruising on his right hand. Medical treatment was needed for the injury. The vehicle was taken to a local dealer, where it was diagnosed, and the contact was advised that the sunroof assembly was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 111,000.

I purchased a 2018 Honda Odyssey and reported during my 7-day inspection window that the transmission was acting sluggish. The Carvana-authorized inspection service (Pep Boys) claimed the transmission was fine. Over time it showed more and more signs of failure until it completely failed. On the directive of the seller (Carvana) and warranty administrator (SilverRock), the vehicle was taken to an authorized Pep Boys facility for a complete transmission replacement. Less than two days after picking up the vehicle, the replacement transmission suffered a complete failure on a public roadway. The vehicle suddenly lost all acceleration and forced itself into 'limp mode' on a highway, and loss of steering control, nearly causing a severe collision. The vehicle is inherently unsafe, and the authorized repair network has failed to provide a merchantable or safe repair, creating an immediate life-threatening hazard.

While driving on a clear road, with or without heavy traffic, the collision mitigation warning shows up on the dashboard display. Sometimes the warning for the collision system goes off and the system tries to brake and jerk the wheel. If I have the wheel firmly I can correct it and it resolves. It can happen on a clear road with no one around or in heavy traffic. Yesterday it happened in a single lane with barriers on both sides, a road around Logan Airport in Boston, with no vehicles ahead of me. The car tried to steer me into the barrier. I was doing less than 25 MPH. The warning had been going off for a while but now that the steering and braking are involved it’s much more serious. I reported it to the dealer. They said they did a system check and couldn’t find a fault. The braking and steering problem first occurred about a month ago. The warning by itself has been happening intermittently for over a year. This happens even when the collision mitigation system is turned OFF. This is a terribly unsafe issue. If my wife had been driving I don’t know if she could have corrected. PLEASE ACT AND ISSUE A RECALL!

The rear spring suffered a catastrophic failure, breaking while driving with occupants inside vehicle. The rear coil springs suffer from poor materials or paint protection causing premature failure and rust.

Vehicle: 2018 Honda Odyssey Component: Suspension – Rear Shock Absorbers Mileage at Failure: ~50,000 miles I am submitting this complaint to report a premature and potentially unsafe failure of the rear shock absorbers on my 2018 Honda Odyssey, as well as what appears to be a systemic defect affecting 2018–2024 Honda Odyssey vehicles. At approximately 50,000 miles, the rear shocks on my vehicle failed suddenly. Inspection revealed that the upper portion of the shock absorber housing had rusted completely through the metal, causing the internal hydraulic fluid to leak out and rendering the shock absorber inoperable. This is not surface corrosion—the metal housing itself failed structurally. The affected component is the factory-installed rear shock absorber, Honda part number 52610-THR-A02. Based on owner reports and service findings, this failure appears to be common across 2018–2024 Honda Odyssey models, typically occurring between 50,000 and 80,000 miles, often shortly after the factory warranty expires. Rear shock absorbers are sealed, safety-critical suspension components. They are not expected to rust through the metal housing or leak fluid within 6–7 years of normal use. This type of failure suggests a materials, coating, or design defect, rather than normal wear and tear. Failure of rear shocks can negatively impact vehicle stability, ride control, braking performance, and passenger safety, particularly in emergency maneuvers or adverse road conditions. Given that the Honda Odyssey is marketed as a family vehicle, this raises significant safety concerns. Due to the repeated nature of this failure across multiple model years, I believe this issue warrants investigation by NHTSA for a potential defect trend and consideration of corrective action.

While my child was riding in the second row drivers side captains chair of my 2018 Odyssey, she fell asleep and unknowingly moved the shoulder strap portion of the seat belt behind her head/ upper body. I was driving and could not see that the belt had been moved because she was seated behind me and was also covered by a blanket. After the vehicle was parked, she unbuckled the seat belt and attempted to exit the vehicle. As she got out, the seat belt retracted and tightened around her abdomen and torso, trapping her against her seat. The belt became extremely tight and we were unable to free her after 20 minutes of struggling to create slack and slide her out.The pressure from the belt cause visible injuries to her abdomen. Because we could not safely release her, we were forced to cut the seat belt. The damaged seat belt was inspected by a Honda dealership, which recommended replacement of the entire seat assembly, costing $3,000. Honda customer relations was also notified and provided us with a case number. I am submitting this report because a child was trapped by the seat belt during normal vehicle use, requiring the belt to be cut to safely free her.

On 4/30/26 my 10 year old son was sitting in the middle row behind the driver buckled in his seatbelt. The middle row, middle seatbelt (that comes down from ceiling) got wrapped around his neck and kept tightening. He yelled for help. I was driving and saw in my rearview mirror that my son was being pulled up by his neck from the seatbelt in the ceiling. I pulled into a shopping center immediately to try to help him. I could not reach down in between the seats to unhook it because the more I tried to release him, the more it would tighten. That seatbelt requires a tool to be pressed into the lock to release it and the more I tried to get to the seatbelt to unfasten it the more it was tightening and pulling my son up (he was literally starting to hang from the ceiling). I unhooked his seatbelt so he could push himself up to try to release some of the tension around his neck. I wound up running into a Michaels store screaming that I needed scissors because my son was hanging from a seatbelt. She gave me scissors and I went back out and cut the seatbelt to release my son from the seatbelt noose around his neck. He had red marks around his neck afterwards. I still have the cut seatbelt and the other half retracted into the ceiling. Research has confirmed that there have been other reports of issues with children having to be cut out of seatbelts due to the Automatic Locking Retractor (ALR) in Honda Odysseys, model years 2011, 2012, 2013, 2014 and my model 2018. I called Honda corporate on 6/8/26 and filed a complaint. I was told I would receive an email response. I have not received an email or any response. So I called Honda corporate again on 6/25/26 and was told someone would reach out to me, but they could not tell me anything over the phone at that time. I made an appointment at my Honda dealership to have the seatbelt replaced, but have been waiting on a response from Honda corporate before doing any repairs.

The contact owns a 2018 Honda Odyssey. The contact stated that while a customer on Turo was driving the vehicle, the instrument panel warning lights flashed and the climate control system failed to function. The vehicle was restarted multiple times, but the instrument panel warning lights remained illuminated. The contact stated that while being driven, the vehicle was pulled over by law enforcement because the taillights failed completely. The vehicle was taken to the dealer, where it was diagnosed that the gauge control module had failed due to corrosion from water damage. Upon further inspection during the replacement, the dealer discovered additional failures within the body control module and the taillight wiring harness. Technicians determined that the electrical failures were caused by water leaking from the rear windshield into the tailgate area. The vehicle was repaired; however, the water leak source was not addressed or sealed. The manufacturer was notified of the failure. The failure mileage was 144,411.

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.

I removed the car seat cover to wash and discovered there was a crack in the hard foam of the head piece. It completely separated the two side of the headpiece and the side was coming away from the hard plastic base on one side. When I removed the cover completely, half of the head rest piece fell off. This is the 2nd Chicco MyFit car seat that I have had because the first one was replaced under warranty for this very same problem. The biggest issue is that the foam is breaking and coming loose underneath the cover so I don't know how long it has been like this. This compromises the safety of my child if we were to get in an accident. The head protection is obviously important, especially in a side impact crash but with the hard foam broken in half, it is useless.

THE BRIDGESTONE TURANZA TIRES ARE NOT HOLDING UP I HAVE POPPED BOTH FRONT TIRES- ON SEPARATE INCIDENTS IN THE PAST 2 MONTHS SINCE IN GOT THE VAN. I PREVIOUSLY DROVE A SIENNA AND A PATHFINDER AND HAVE NOT HAD A POPPED TIRE BEFORE .

The contact owns a 2018 Honda Odyssey with Vredestein Tires, Tire Line: Quatrac Pro Plus, Tire Size: 235/60/R18, DOT Number: 023 45E427 1425. The contact stated that the side wall on the front passenger tire had begun to form bubbles. The tire distributor was notified of the failure, and the tire was replaced however shortly after having the new tire replaced with the front driver's side, and the front drivers side placed on the front passenger side, the contact stated that shortly after upon inspection it was discovered that the tire was shredding and chunking on the shoulder. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The tire was a replacement tire. The vehicle failure mileage was 86,767 the tire failure milage was 3,200
