2018 HONDA ODYSSEY Power Train Problems

Bought vehicle new at Millennium Honda, Hempstead New York.Vehicle is not going into reverse when vehicle gets hot. My mileage is 40,512 took it Millennium Honda on October 4, 2025, for diagnostic testing error code P0736 was diagnosed and that my transmission would need’s replacing at a cost of $11,495 for parts and labor, because I was a couple months out of warranty. I have since reached out to Corporate but negative response. I am unable to use my vehicle since which have been at an additional expense to me as I have to maintain insurance and pay for bus, train and taxi services. Not sure what kind of assistance you can offer or even assist in investigating why a vehicle with 40,000 would need a new transmission after moderate use. Thanks for your consideration on this matter.

Upon pressing the accelerator from a complete stop, the vehicle does not respond right away. The main incident was when traveling around 50 miles per hour on a highway, the van shifted into neutral on its own and the accelerator would not respond. An error message of transmission failure showed on the dash briefly. The van had to coast through traffic an eventually push off the road.

Vehicle lags in acceleration from a slow rolling start, at random times. There is a clear 1-2 second lag in the acceleration, then a sudden harsh shift into gear. Mostly happens during turns, and if traffic is present, may cause an accident. Also when traveling at low speeds 20-35 mph, there is a transmission jutter. Have spoken with service reps at dealerships and they claim to have no knowledge of these transmission issues

2018 Honda Odyssey (10-speed automatic transmission) What happened: The vehicle is experiencing intermittent loss of reverse and delayed gear engagement from a stop. When shifting into reverse or drive, the engine revs but the vehicle does not immediately move, then jerks into gear. The issue is worse when cold. Warning lights / codes: Check Engine Light on. Honda dealer retrieved diagnostic trouble code P0763 – Shift Solenoid C Electrical. The code returned as a hard code after being cleared. Safety risk: The vehicle hesitates or fails to move when shifting into reverse or from a stop, creating a safety risk in traffic, parking situations, and when backing up. Current status: Diagnosed by Honda dealership. Repair recommended. Honda corporate case opened.

After I received a software update for my 2018 Honda Odyssey Elite the car has been stalling when idle. It is very dangerous because I will be at a stop light in drive, and the vehicle will shut off with no power. Cars will be behind me or no cars, and I have almost been rear ended. I did not have this problem until I received the new software update. It keeps occurring more and more often.

The transmission failed at 108k miles. Honda is charging 10000USD for repair. They want to replace the 9 speed transmission. This transmission is notorious for failure and Honda hasn’t issued a recall yet.

My vehicle repeatedly and unexpectedly shifts into neutral while in Drive, causing a sudden loss of power in traffic. This has happened multiple times without any input from me and has nearly caused a crash.

Summary: Engine seized due to internal bearing failure with metal shavings found in oil filter. Full Description: My 2018 Honda Odyssey experienced a sudden engine failure around 116,500 miles. The dealer confirmed the engine is seized and showed significant metal shavings in the oil filter and pan. I have performed all maintenance according to Honda’s recommended schedule using the correct oil and filters. Honda corporate denied assistance based solely on mileage, even though this issue matches symptoms described in current NHTSA investigation PE25-001 (connecting rod bearing failure in Honda 3.5L V6 engines). There were no prior warnings other than a brief check-engine light and rough running before the engine locked up. The vehicle was in motion at the time and could have caused a hazardous stall, serious injury, or death. Given that Honda has issued recalls for similar rod bearing defects in other model years (2015–2020) and this failure mode...

Recently had the fuel pump recall completed. Within days had intermittent dash emissions light come on then go away. Then a few weeks later, while driving, my odyssey put itself into N and I coasted to a stop. It would not allow me to put the car into P or anything. I had to put the emergency brake on in order to not roll forward. The van at that point would not shift into any gear. It was towed to dealership and I was given the following 2K dollar repair needs. PROBLEM. ADVISE. [Other]: TCM (TRANSMISSION CONTROL MODULE) AND TRANSMISSION SUB-HARNESS Needs replaced.

The contact owns a 2018 Honda Odyssey. The contact stated that while driving at various speeds, the message "Engine Management System Failure" was displayed on the instrument panel. In addition, the contact stated that the vehicle hesitated while depressing the accelerator pedal, with an abnormal clicking sound coming from the vehicle. The contact had taken the vehicle to an independent mechanic and was informed that there was a failure with the engine and the transmission. The dealer was then notified of the failure and the contact was informed that there were no recalls on the VIN related to the engine or the transmission. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 150,000.

On [XXX], while driving in traffic, my 2018 Honda Odyssey suddenly and without warning shifted itself into Park. The vehicle slammed to a stop in the middle of an intersection, stranding my family and creating a serious risk of collision and injury. The vehicle would not move afterward and had to be towed from the scene. After the failure, the dashboard displayed multiple warnings: “Transmission Problem,” “Stop Driving When Safe,” “Emission System Problem,” and *“Blind Spot Information System Problem.” The gear shift indicator also blinked. The Odyssey has remained undrivable since the incident. The vehicle is at Stockton 12 Honda in Sandy, Utah, where the dealer confirmed a hard transmission failure (RO #[XXX]). Honda Corporate opened two cases (#[XXX] and #[XXX]). Despite my repeated calls and emails, Honda’s assigned case manager verbally denied coverage on Sept 12, 2025, stating the denial would only be reflected in Honda’s internal case notes....

2018 Honda Odyssey gear shifting switch letters are rubbing off. This caused the drive to click wrong button as they do not have letters to identify the functionality of the each button. This can cause accidents. I see many online forums customers are discussing the same issue. [XXX] [XXX] / [XXX] [XXX] This is manufacture defect and please be kind to investigate it.

Engine has been running very rough the last 20k miles, and East Coast Honda in Surfside Beach, SC noted engine bearing wear prior to the rough engine performance during a service visit in May 2023. In June-July 2025 driving on [XXX] driving between Washington D.C. and Surfside Beach, SC, we went to pass and the engine cut RPM's drastically and went into 'limp mode' nearly causing an accident with the sudden decrease in speed. We have asked American Honda Customer Service [800-999-1009] to provide an engine evaluation but they have declined and have stated our VIN is not included in the rod bearing recall/TSB. We did mentioned about the further investigation for 2018 Honda Odyssey's but was advised any action we take would not be compensated since the vehicle is out of warranty by date and mileage (73,000 miles).

Vehicle has a vibrating shake when you go about 26 to 40 miles per hour like it does not know on what gear to be me I took the car multiple times to the dealership, and after charging me hundreds of dollars they had the face to say it is what it is. That the design of the car. I even called the corporate and no one really cared. I am always scarred that engine or transmission will fail and cause an accident. On the last trip, as I was stuck in traffic, stop and go was hard on this condition as car wants to think on what gear to be.

The transmission is very jerky and has completely lost power before. It has refused to shift and stalled in the middle of the road. It is very scary.

Rod knock diagnosed and confirmed by dealership July 15, 2025. Van is currently at dealership and is available for inspection. I have paused work to allow Honda (case 15705425) and now this team the opportunity to diagnose and inspect first hand. Inspection and first hand visuals have only been completed by certified Honda dealerships. All warnings and my concerns are documented in our ROs with Honda dealerships. When any light or reminder came on, I immediately took the van to Honda for service. Safety: slow starts and sluggish acceleration. Noise that was not normal. Out to eat 30 minutes away from home July 13 and van wouldn’t start. Dealership thought initially battery but then kept van overnight and nod rock confirmed. Also repaired back suspension. Additional details: Problem has been reproduced and confirmed. Have been experiencing slow start, van not driving properly. Our family went out to lunch July 13...

The contact owns a 2018 Honda Odyssey. The contact stated that while depressing the accelerator pedal, the vehicle failed to respond as intended. The contact stated that the failure has caused the vehicle to hesitate while attempting to accelerate. The contact stated that the failure had occurred on several occasions while driving on the interstate and the freeway. A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the software needed to be updated and the vehicle needed to be driven approximately five thousand miles to correct the failure. The vehicle was repaired, and the transmission was replaced once before. The manufacturer was notified of the failure; however, the warranty department failed to return the call. The approximate failure mileage was 108,900.

As reported previously to Honda the vehicle jerks when accelerating at high speeds.It was recommended to die a transmission flush which was performed and did not resolve the issue.slow acceleration at times is also a safety issue especially on highways.

I have had four diagnostics on this vehicle and it's pointing to sensors which are inside the transmission transmission was not leaking and wasn't slipping or nothing I went to get in the vehicle after it was sitting for an hour and I put it in reverse it went right back in the park I put it in dry went right back in the park I couldn't get it out of the park and it was saying on the dash that stop driving one safe transmission problem emission system problems okay like a four diagnostics that are saying that it is sensors transmission pressure sensor A park neutral switch is bad power source failure steering angle low voltage sensor failure four different things I cannot get any help I hear a bunch of different stories some are saying the transmission not so we're saying it's not a transmission isn't slipping...

The contact owns a 2018 Honda Odyssey. The contact stated when the vehicle was shifted into park(P), the contact was unable to shift the vehicle out of park(P) into drive(D). The contact had the vehicle towed to a dealer. The vehicle was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 19V299000 (Power Train, Electrical System); however, the VIN was not included in the recall. The failure mileage was approximately 700.

Honda issued a recall on the fuel pump December 2023. They did not have any parts available to replace mine. I had brought in my Odyssey Elite to Space Coast Honda multiple times before the recall stating my engine wouldn't crank. I was unable to get the fuel pump replaced until December 5, 2024. ONE YEAR after the recall. I am now getting Emissions System Problems and Stop Driving When Safe Engine Temperature Too Hot. The dignostics that were pulled were P219A Secondary P219A, P0420, P219A. Also, my intake manifold gaskets are leaking coolant. I have had nothing but problems with this van since April 5, 2023 with my car not starting and stalling. My kids and I were stranded at their school two times and there were multiple times at my work. I don't believe I should have to pay thousands of dollars for these items to be replaced...

Transmission failure. We had issues with acceleration and hesitation. When brought to the dealership they didn’t find anything wrong, but then the transmission ended up failing completely.

The vehicle would make noises and stalls during accelerations and decelerations. It would struggle to shift into gear, especially from 1st to 2nd gear. When the vehicle comes to a stop at traffic lights or stop signs, it's really hard to get the car to move when accelerating. In high speed on the highway, the vehicle would struggle to increase speed when accelerating and the vehicle would automatically slow down and get weighted down. This would result in having to pull over. Sometimes, the vehicle would not be able to be put into Park, and automatically shifts to Neutral not allowing it to be put into Park mode. When attempting to put it back onto Drive, the vehicle would not go and emission and transmission warning would start flashing. The majority of the time, the emission or transmission warnings would not flash. This is very frightening because I was not...

9 speed transmission issue: Ever since I purchased this vehicle around 50,000 miles in February of 2021 (mileage currently at 118,048), I noticed a very obvious delay in acceleration from a complete stop. Changing to eco drive mode and sport mode changes slightly, but still has delay. Transmission fluid has been changed 3 times since owning this vehicle and everytime it has, there was no noticeable changes in symptoms. Delayed acceleration occurs more consistently at normal operating temperatures. Brought vehicle to honda dealership after purchasing. They performed a TCM software update. Problem still occurs to this day. Multiple occasions occured where me and my girlfriend are driving and attempting to make a safe left turn only to proceed, but in process of attempt, the vehicle delays while facing oncoming traffic.

My 2018 Honda Odyssey experienced a heavy snowfall in January 2025. The control panel displayed an alarm, Power Tailgate Problem , and the trunk door could not be opened. I asked a professional who pointed out that it is usually due to water intrusion into the control unit located on the rear driver's side body panel, which causes the tailgate to fail to open, close normally, or even open accidentally. They believe that this is a manufacturing defect caused by the manufacturer and there is a safety hazard. For safety reasons, I went to the dealer for an inspection. They said they could not find the cause but that the control panel was broken and needed to be replaced. I had to spend a lot of money to replace it. But I still think that the problem was caused by the manufacturer itself.

In several occasions there is a delay in acceleration. This typically is happening when I take off from a stop sign and turning, others I have literally been on highway merging and loss all acceleration Al though I can hear rpm ramp up, there is no action till 10-15 seconds later. I am very lucky no was injured in that instance and could have been a terrible accident going 70+. I see this is an ongoing issue, and because it is not consistent in manner people fail to repair/research issue.

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.

At approximately 70,000 miles, vehicle transmission failed after intermittently falling to go into reverse and transmission warning system shifting vehicle down while driving. Rebuild parts not available from manufacturer, replaced transmission with used part. Immediately after putting car back into service, engine began to knock severely. Dealer recommended full engine replacement. Car currently not drivable and has been parked for past 13 months.

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...

The contact owns a 2018 Honda Odyssey. The contact stated while stopped, the accelerator pedal was depressed; however, the vehicle hesitated while accelerating. On another occasion, the contact stated that while his wife was driving, the message "Stop Driving when Safe - Transmission Failure - See Owner’s Manual" was displayed. The contact stated that his wife pulled over to the shoulder of the road and parked the vehicle, and the vehicle became difficult to shift out of park. In addition, the contact stated that the RPM occasionally fluctuated and there was a delay with the vehicle responding. The contact also stated that the transmission was shifting hard. The vehicle was taken to a local dealer where it was diagnosed with an internal cylinder failure and that the 9-speed manual transmission needed to be replaced. The vehicle was not repaired. The vehicle was taken back to the same local dealer several...

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

UNKNOWN At random times I will push the gas pedal and the car does not engage at all to move. I will lift my foot up and down trying to engage the engine and it won’t. After a few times it will catch and the car takes off making the tires squeal, spin or jerk. It happens at random times, no warnings whatsoever that there’s a problem. It is very dangerous at intersections when turning left on green lights, when pulling out of parking lots. It’s to the point I am afraid to drive it at busy traffic times because it happens so often and I’m afraid of getting hit while my car will not move. We have told the dealership and they suggested we wait for the fuel pump recall to be readily available. I looked in forums and this seems to be a major problem for many other...

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 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.

We started hearing a metal knocking type noise on start-up and acceleration. We took it to a mechanic who diagnosed it as a rod-bearing problem. Then we took it to the Honda dealership thinking it was related to recall 23V751000 which also deals with 2018 Honda Odysseys, but for some reason our VIN was not included in that recall even though our problem sounds exactly like what is mentioned in the recall. The dealership said we are 6 months out of warranty and would therefore need a new engine. I used one costs $9,000 and a new one would be $22,000.

See attached document for complaint.

Forward collision warning comes up on vehicle. There is a problem with the transmission. the car automatically shifts itself from D to S.

I bought new and have 59,000 miles on the car. During the past year or two, when I get to a stop sign and about to cross or turn into a busy road (that has no traffic signs for the cars traveling on that road), the car hesitates when I step on the gas pedal, then after a second or two, the car lurches forward (abruptly) while screeching the tires. My analysis is that there is something about making several complete stops in short succession (as a driver would do in an attempt to inch into a busy intersection of fast moving traffic in order to get a better view and position the car for a smoother merge) which triggers the car to stall for a second or two. I say this because it does not happen at any other types of intersections. The danger here is that a second...

The vehicle often hesitates to accelerate when pressing the fuel peddle. This mostly happens when backing out of a driveway and placing the gear into drive but also has happened after coming to a full stop and then pulling out. The hesitation lasts about 1-3 seconds and could lead to a collision if I decide to pull out in front of oncoming traffic and anticipate the car to accelerate rather fast. Often, during the hesitation the instinct is to press the gas pedal harder, in which case, when the vehicle does accelerate it will spin the tires, making forward progress even more frustration and dangerous. This happens with both drivers in the family, it is not isolated to just once person's style of driving. This becomes a safety issue if you expect to merge into traffic and the vehicle does not respond. we have adjusted our driving habits in this...

At critical accelerating situations (turning, merging, passing...) the minivan will hesitate, and no power is delivered to the wheels. As a result, the car does not perform as intended and can cause an accident when turning, merging, or attempting to pass. The only resolution is to remove any pressure from the accelerator and allow the car 1-2 seconds to recover, then you can usually accelerate slowly. Sometimes this has happened multiple times in the same accelerating event. This happens on 2018-2019 Honda Odysseys with 3.5l V6 with ZF 9HP transmissions. This has happened multiple times and Honda has failed to correct this issue. This is a known issue and has been part of a class action lawsuit. The most recent incident occured yesterday and the vehicle automatically shifted into Neutral and would no long drive.

2018 Honda Odyssey failed transmission systems. This vehicle had recalls in regard to TCM module and softwares in past. Normally transmission system should last well over 150,000 miles for this type of vehicle. My car failed at 74000 miles. That too without any advanced warning. Vehicle was maintained and serviced at same dealership regularly where it was purchased. Honda is claiming its outside their 60000 mile powertrain warranty. Honda expects me to pay over 10,000 dollars for repair. I believe my vehicle is having issues with transmission related to TCM module recall of 2019 and Recall 04v176 of 2023. Honda is refusing to look in to possibility of my vehicle's issue could possibly related to those recalls. I believe those recalls need to be looked at and my vehicle should have been involved in those recalls. I have documented proof for all services performed and current vehicle inspection report.

My 2018 Honda Odyssey doesn't have any current vehicle recalls but it's is experiencing the engine stall while driving, the power sliding floors not locking properly and the power trunk making a grinding noise when it opens and closes. I had the vehicle inspected at the local Honda dealership and they told me there was nothing they could do about the vehicle stalling, the power doors not closing and the trunk grinding. From releasing the brake and pressing the gas, the vehicle will stall and then spin the tires as if I'm racing or burning rubber.

While driving, the transmission will go into limp mode and will not drive over 40 mph. Comes on and off intermittently. Will not show error code. Was almost rear ended by semi trailer when happened

On the week of May 3rd my car began to shift into different gears with no notice or reason while driving, when it would do this it would show a warning signal on the dash that stated"transmission issue!" And the gear letter would flash on the dash. I brought the car in to the dealership it was purchased from (Ira Honda Saco, ME) as the car was shifting into reverse and park while driving causing significant safety issues for myself and my children in the car. When I arrived I was told there was issue with loaners although the service employee was great in helping me find one eventually that day as I'm a solo parent with multiple children. However, when I brought the car I said there was a recall on the transmission for this exact issue. I was told my make model and year matched but not the...

At around 25 miles per hour the vehicle has a transmission issue where the vehicle seems to hesitate, then downshift causing the vehicle to lurch forward. This happens regularly and started sometime before I acquired the vehicle with 48k miles. Honda dealer had no fix to the problem.

On April 13th, 2024 our son was driving the family 2018 Honda Odyssey (Approx 83,000 miles) in a nearby city. He was driving at 43 mph when the vehicle shifted from drive to neutral without his shifting it. He tried to brake using the brake pedal but was unable to stop or slow the vehicle. He also tried to accelerate and was unable to accelerate the vehicle. All the lights on the dashboard lit up and he was forced to use the emergency brake to stop the minivan. A good samaritan stopped and assuming that the battery was the problem, tried to help jump-start the vehicle -- but they were unable to start the car. Our son called us, and I drove 20 or so miles to his location. After trying a jump box in the vehicle, we called AAA. After trying a jump start and a new battery, At...

When I drive the van just stops working. So I have pulled out into the street to cross traffic and on many occasions the car just won't drive like the transmission isn't in gear. It will eventually get into gear and go again but I have almost been hit before. I think my car should've been included in the transmission recall.

My van driving on the highway and pop up two error cods at the same time, one is transmission system problem and the other is blind spot info system problem. Check it out with code P0741. And this incident happened 7 times in the past 6 months.
