Several times in recent years my car will start sputtering and misfire, losing significant power. Last time I was getting onto the freeway and it was quite dangerous as I was unable to accelerate sufficiently. My engine light also went on. The Honda dealership diagnosed the problem as a problem with the pistons, which needed replacing at a cost of some $4,000. The dealership shared that they were aware of this problem and that Honda had a newly designed piston to replace it. This seems to be the same problem covered by a RECALL for Honda Odyssey's 2011-2013 - but it does not cover my 2015 model. I am attaching info on the recall (Soto et al v. Amer. Honda Motor Co, Case No. 3:12-cv-1377-SI)

- Summerland, CA, USA

The contact owns a 2015 Honda Odyssey. The contact stated while driving approximately 35 MPH, the check engine warning light illuminated. The vehicle was taken to the dealer to be diagnosed. The mechanic informed the contact of spark plugs and oil contamination causing engine damage. The contact stated that a temporary repair was performed however, the failure recurred. The manufacturer was notified of the failure. The approximate failure mileage was 88,652.

- Fremont, CA, USA

Piston rings in cylinders 1-3 failed and allow oil to foul spark plugs and causes misfires. Same issue they have on the older models and subject to class action suit. TSB has been released, but repair charge for this continued design flaw estimated over $4000. 140,791 miles, services maintained. A search of the Honda blogs show this to be a continuing issue for many owners.

- Savannah, GA, USA

Very dangerous drivetrain issue. Transmission shifting issues led the transmission to total failure even after a recommended transmission flush and fill by a reputable Honda dealer. Issue was confirmed by an independent local repair shop. The vehicle itself has low mileage, (@69,600 mi.) No warning lamps prior to the transmission malfunction and failure.

- Culpeper, VA, USA

The Spool Valve leak oil onto the alternator causing the battery not be recharged and the car powering off and shutting down on the highway. This happened on my way from Kansas City Kansas. With the electrical unit completely shut down due to oil leak from the spool valve that caused the alternator to short circuit, my car slowed down from 65 mph to a halt in less than 10 seconds. Luckily enough I was at an exit and hence maneuvered the car to safety. Had I been on a bridge or narrow road with no shoulder, it could have led to potentially deathly situation. Took My car to a Honda dealer in davenport, where I was told the cause was a spool valve leak that is very common with Honda Odysseys built from 2010 to 2018. The issue was not inspected by the police nor my insurance. There was no warning other than my battery light that came on the dash board. The light came on 20 minutes prior to the car shutting down.

The van shifts very odd when going forward. It doesn-??t shift smooth from 2-3 gear and it-??s not just our van my parents have the exact same year and model and it does it in theirs as well! I have read many complaints online about this but I don-??t know if it-??s the motor or the transmission but something is wrong with it. Being that we have literally 2 of the same year and model vans I can-??t see where this is a one off deal. I think there has to be something to it.

Check engine light came on upon starting vehicle. Vehicle was stationary and in park. Obd reader shows cylinder 3 misfire. Mechanic reports fouled plug and oil control issues due to vcm. All maintenance performed on schedule by ase certified mechanic. Vehicle has 73000 miles.

- Grapevine, TX, USA

While driving, the idle started to become rough and engine vibration increased. Check engine light and additional warning lights appeared in the dash. Error code P0302 was the primary error code for misfire cylinder 2 when the errors were scanned at home and confirmed by shop affiliated with car dealership. The spark plug in cylinder 2 was inspected and identified to be fouled and covered in oil. Additionally the ceramic was missing from the spark plug. This vehicle only has 50,785 miles, and this issue is similar to the class action lawsuit/service bulletin 13-081 issued to Honda vehicles (including Honda Odyssey 2011-2013). However, this time Honda is telling me that this issue is not a powertrain warranty issue and that I am responsible for the cost of repairs although the problem follows the exact decision matrix found in this service bulletin from the logged error code to the fouled spark plug in a young motor. This vehicle has been serviced by the same Honda dealership since I purchased the vehicle used at 16K miles.

- Jacksonville, FL, USA

After driving a few miles under normal conditions we parked our minivan in our parking spot behind our house. While getting out of the minivan there was an odor and a tiny bit of smoke from the engine compartment. After waiting a couple minutes the smoke seemed to go away. We left the minivan parked and about 10-20 minutes later it started on fire and we received a call from our neighbors that the fire department had been called and they were putting out the fire. I am uploading a picture of the burnt minivan and the last service record for a regular oil change on 12/29/2018

- Chicago, IL, USA

The contact owned a 2015 Honda Odyssey. While pulling in the garage, the vehicle caught fire. The fire department extinguished the fire. The contact had no recollection of a police report being filed. There were no injuries. The fire department stated that the firewall was the cause of the fire. The vehicle was destroyed. The dealer and manufacturer were not contacted. The failure mileage was unknown.

- Willoughby, OH, USA

The vehicle makes hard shifts in lower gears, causing a lack of acceleration and then a lurch with engine/transmission clunk. Occurs when accelerating from a slowed or stopped position, so vehicle can be stationary or in motion when this occurs. Has happened before but dealership could not replicate. Similar complaints with lack of resolution found in online forums as well. Presents a significant safety concern since acceleration is altered and shifting is slowed. Has occured on residential roads and highway and at varying outdoor temperatures.

My Honda Odyssey was experiencing a bucking sensation that occurred periodically but stopped after being restarted. Brought vehicle to dealer, who didn't find actual problem but during an evaluation of the vehicle detected a weakened engine mount and leaking spool valve, both of which could have lead to a loss of the engine if condition persisted. Both needed replacement at high cost, and to demonstrate that this was not a singular event was seen in another customer's Odyssey that afternoon. Considering so-called reliability of Honda, there's no reason for engine mount to have issues and there was a hint that there is an ongoing problem with the spool valve. This is something that could have lead to serious issues. However the original problem involving the 'slipping of the transmission' still persists and represents another potential safety issue with this van. The 'slipping issue' occurs when accelerating or decelerating around 20 mph or when achieving highway speeds off ramp. It does stop after the vehicle is turned off and then turned on again. Some of these issues may be more common than Honda is letting on.

After reversing out of the driveway (slowly) and putting the car in drive I noticed a hard clunking sound. I thought it was just a rough shift. When I continued to drive down my block 5-15 mph to the stop sign it continued. It feels like another vehicle is crashing into you and slamming on the breaks. You lose 'control' of the gas pedal (your foot is on the gas, you hear a large clunk and the gas pedal doesn't make you go forward anymore, for a couple seconds) it is a nerve-racking feeling and isn't correct. My vehicle was purchased in 2014 (2015 model) it only has 32K miles on it. Regular routine maintenance has been performed. It has happened a handful of times in the past 3-4 months and seems to temporarily correct itself once the car is put in park, turned off and turned back on... I have not been able to recreate it for anyone while they are in the vehicle, except my children who are scared when it happens. When the car is in park and goes to drive there is also a harsh transition; a clunk happens when shifting. It is an automatic transmission. Yesterday 10/2/18; I drove roughly a mile with no issues until I came to a stop sign, where I didn't make a complete stop and it started happening again. I waited to post, it happened again this morning 10/4/2018; the van was cold (parked all night) backed up, came to a complete stop, put it in drive, clunked like it missed firts gear, then continued to clunk as I drove between 40 and 60 feet. Stopped, put it in park, turned it back on and drove away with no issue. Shall see what happens after work today.

2015 Odyssey vehicle's jerking experience started during a stop and go traffic. With three kids and two adults, we were extremely frightened. The vehicle jerked violently when I pushed the gas pedal during the low speed, 5-20 mph. I went away later that day and we went about our business. After we go back to our home, went to the local Honda dealer after making an appointment. Of course, we were not able to replicate the violent jerk experience. They said until they see it, there's nothing they can do. It was initially around 30K miles when this started now over. It has not happened in a few months but Honda is not taking this seriously.

- Buena Park, CA, USA

When I pulled up to a parking spot and took my foot off the gas peddle and placed it on the break the engine started to accelerate and engine RPM's climbed about 1000 RPM's. the car's transmission was still in drive (D). I had to force the transmission into park (P) and push the start/stop button to shut the engine off. This incident almost caused me to rear end a parked car.

Had my vehicle drove on freeway for an hour and when pulling on to a shopping center, there was a stop and go. At that point the engine/transmission starting jerking and shaking. There was sound from engine/tranmission like some metal crushing or breaking. Stopped the vehicle for a while and the issue didn't happen again. Dealer not able to replicate this issue and so no fix.
