2018 Honda Odyssey Problems

while driving at 35 mph a vehicle well ahead of me made a left turn exiting the roadway. My vehicle suddenly applied the brakes even though there was no longer a vehicle in my path. I tried to increase the accelerator, but the vehicle was slow to respond to this. luckily there was not another car directly behind me. This exact problem had occurred many time previously.

The contact owns a 2018 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 26V423000 (Back Over Prevention); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

Failure of the forward-looking multipurpose camera after a simple battery change. Many safety features are now inoperative including emergency braking, lane keeping assist, adaptive cruise control, among others. Ultimately, a routine maintenance item (battery replacement) is causing the failure of vehicle safety systems.

The contact’s daughter owns a 2018 Honda Odyssey. The contact stated that after the vehicle was idling at a stoplight and then attempting to accelerate after the light turned green, there was a loud clanking sound coming from the front of the vehicle. The owner then became aware of white smoke coming from the engine compartment. The vehicle was coasted to the side of the road and the vehicle stalled. After the vehicle stalled, there was no smoke coming from the vehicle. The vehicle was towed to the dealer but was not diagnosed or repaired. The contact became aware that vehicles of the same year, make, and model were known to experience engine failures at approximately100,000 miles. The contact stated that the vehicle was inspected at approximately 100,000 miles and the rear main seal was replaced during the routine service and maintenance. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

I own a 2018 Honda Odyssey EX-L (VIN [XXX]). The vehicle experienced a sudden loss of power and entered limp mode, with multiple safety and driver-assistance systems shutting down at once (adaptive cruise, braking assist, lane/road departure mitigation, EPS, etc.). A Honda dealer (Allen Honda, College Station, TX) retrieved DTC P0369 and documented that the front camshaft is worn and has thrust forward, contacting the camshaft position (CMP/TDC) sensor and damaging the thrust plate. The dealer is recommending an internal engine repair costing several thousand dollars. I am very concerned because Honda has already acknowledged serious engine defects in this same J35 V6 family under Recall 23V751 (connecting rod bearing wear leading to engine damage and stall) for 2018–2019 Odyssey, yet my dealer states my VIN is “not part of the recall” and that this is a “separate issue.” In practice, I am seeing a major internal engine failure that causes sudden derate and disables multiple safety systems, but I am being told there is no recall coverage or assistance simply because my individual VIN falls outside Honda’s current recall production range. I am requesting that NHTSA review this incident as a potential recall exclusion problem: owners with the same engine family and serious internal failures are being denied recall coverage on a technical VIN cutoff, even though the safety consequence—loss of power and shutdown of critical safety systems while driving—is similar to the failures already recognized under Recall 23V751 and the ongoing engine defect investigation. I believe this situation may warrant expansion of existing recall coverage or a new recall campaign for currently excluded VINs like mine, and reimbursement for owners who have already paid for these repairs.

While driving the car lurches as it shifts gears. This had gone on for quite some time but no codes have been thrown. This last time the car lurched so badly at the beginning of acceleration that I thought it was going to stall. It did not, but lights began flashing on the dash and when codes were (finally) thrown I was told I needed a new transmission altogether.

I am reporting American Honda’s ongoing failure to safely remedy critical safety defects and recalls on my 2018 Honda Odyssey (purchased new), resulting in severe vehicle degradation and a life-threatening traffic hazard. The vehicle has been to an authorized dealer over 21 times.SAFETY RECALL NEGLIGENCE & POWERTAIN DAMAGE: At 95k miles, the vehicle displayed active check engine codes P0087 (Low Fuel Pressure), P0420, and P0430. The dealer replaced injectors, but severe fuel issues persisted. The dealer utilized stall tactics, claiming they "could not duplicate" ongoing stalling/hesitation symptoms. When the official fuel pump recall was issued, the bulletin mandated priority service for vehicles actively displaying symptoms. My vehicle met these parameters. However, when I attempted to get the recall performed at 111k and 120k miles, the dealer denied service due to part shortages, instructing me to drive the vehicle until it "completely broke down." Because Honda failed to supply recall parts to a symptomatic vehicle, I was forced to drive it a defective car for an additional 46,000 miles. A replacement pump was installed at 166k miles, but the prolonged forced operation directly caused the high pressure pump to fail and raw fuel to melt both catalytic converters. The dealer issued a $6,000 repair estimate for damage engineered entirely by Honda's recall delays.LIFE-THREATENING TCM FAILURE: One day after a related service visit, the Transmission Control Module suffered a catastrophic electrical failure. The engine completely shut off without warning while I was actively facing four lanes of oncoming traffic, creating an immediate, severe collision risk.BROKEN SLIDING DOORS: The power sliding doors failed under 12 months of ownership. Despite 7+ repair attempts, they remain broken, posing a severe structural/occupant safety hazard. Requests for trade-in intervention since 60k miles were systematically ignored.

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.

Water is leaking through back tailgate every time it rains. Water pools on the back floor and gets into the tailgate control unit. As a result, mold has grown on the floors and water has gotten into the power tailgate control unit causing my tailgate to stop opening and propping up (I have to manually hold the heavy door while lifting items out). This has caused electrical problems with cruise control and several lights blinking on and off my dashboard throughout the duration while driving. I have had the engine and transmission all tested and everything is working properly in that regard. The conclusion is that these electrical malfunctions are due to water damage. I have already had the control unit replaced once a year ago.

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.

Forward camera issue. Brake System light turns on and cruise control, forward brake warning, and LKAS all stop working.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving approximately 10 MPH over a pothole in the roadway, the passenger’s side air bags deployed unintendedly. The contact became aware of NHTSA Campaign Number: 26V227000 (Air Bags). The vehicle was taken to the dealer but was not repaired. The manufacturer was made aware of the failure. The manufacturer informed the contact that the failure reoccurred because the vehicle was not taken in for the reprogramming stated in the recall remedy. The manufacturer informed the contact that the air bag replacement was not covered under the recall. The contact had not received the recall notification before the failure. The manufacturer opened a case. The failure mileage was 120,657.

The contact owns a 2018 Honda Odyssey. The contact stated that while her daughter was driving approximately 25 MPH, the vehicle hit a pothole, and an unknown airbag unexpectedly deployed. The contact stated there was no injury sustained. The contact was notified that the VIN was included in NHTSA Campaign Number: 26V227000 (Air Bags). The contact stated that the dealer was notified of the failure. The manufacturer was made aware of the failure. The failure mileage was approximately 79,000.

The contact owns a 2018 Honda Odyssey. The contact stated that while the vehicle was parked, the driver's side rear sliding door failed to latch as intended. The vehicle was taken to the dealer, where it was diagnosed with a failed door motor. In addition, the contact was informed that the driver's side rear sliding door motor had seized. The contact was informed that the driver's side rear sliding door motor and roller were needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 156,000.

The contact owns a 2018 Honda Odyssey. The contact stated that while the vehicle was parked inside the garage, there was an abnormal sound coming from the vehicle. The contact discovered that the rear hatch door had opened unintendedly and was continuously striking the garage door. After closing the hatch door, the door failed to reopen electronically or manually from the outside. The contact's spouse crawled into the rear trunk area to open the hatch door using the internal emergency release. The manufacturer was not notified of the failure. The failure mileage was approximately 148,756.

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.
