I have now had a flashing check engine twice on my van. The first time it happened next to a well known national mechanic chain while in a car wash. 4 other lights came on all the sudden along with a flashing check engine light. You could feel the engine rumbling. I took it straight to the mechanic next to us and they told me I had a misfire and needed spark plugs and a ignition coil. They did that work and it did temporarily fix the problem. 6 months later the same thing happens. So I took it to a Honda dealer this time. They informed me this is actually a much larger known issue with this engine. The ring on the cylinder shifts/brakes allowing oil to come up and it ruins the spark plug, causing a misfire. They have to do a complete engine rebuild. The mechanic advised Honda knows about this issue and they see it all the time. They also warned me it is dangerous to drive the vehicle when this occurs as the engine could fail and there is a fire risk from the unburned fuel in the exhaust.

My vehicle had check engine line was blinking and I took to the Honda. They immediately diagnosed the code as Cylinder 3 Misfire. Upon checking they identified the root cause is Piston ring needs to replace as oil was leaking in the cylinder. I was told that this can cause severe dame to vehicle and passenger as time engine can stop and cause the fire also. I was told that this issue is well known to Honda. When I reached out to Honda they said that your vehicle is not part of the recall and we cannot reimburse the repair expense. I had maintained my car up to date. There was no maintenances service to replace the piston ring at certain mileage. I am single owner. I am baffled on how this was not the manufacturer issue" How was the scope of the investigation on which vehicle impacted determined? Why was my vin number excluded from recall as certainly it is impacted? This issue put me at the risk with safety. Additionally, why do I need to pay for this Manufactuing defects? Is vehicle manufacturer responsibility not applicable when Car is outside of the warranty due to mileage and years"

My engine needs to be re-ringed after 50000 miles after a repair of the same. Honda settled a class action suit of this issue and the repair was done by an authorized dealer. The pistons rings on certain cylinders my rotate and align which can lead to spark plug fowling. The code is P0301-P0304. This is caused by the VCM that is put on the vehicle to increase gas mileage. Thousands of Honda engines are affected by this problem. Honda needs to do more about this problem. The engines are failing and not lasting as they should.

My wife was driving our 2014 Odyssey. She went to visit a neighbor. As she pulled up in the driveway and applied the brakes the car acceleration engaged. She was unable to stop the car. I hit the neighbors garage door, totaling it and damaged both of their cars inside. She had complained previously about what she had described as a braking problem. The car was taken into Honda service to check out the brakes and they were inspected and the car road tested and nothing was found. Since the accident the body was has been repaired and the car was returned to Honda for a diagnostic check-up and nothing was found again. I have a customer service claim with Honda USA but have not heard back from their claims manager.

The contact owns a 2014 Honda Odyssey. The contact stated that the vehicle hesitated while depressing the accelerator pedal, with the check engine warning light and two other unknown warning lights illuminated. The contact initially had the vehicle towed to an independent mechanic where an oil leak was discovered behind the spark plugs. After the initial failure, the contact had the spark plugs replaced four separate times. The vehicle was also taken to a dealer where it was determined that the cause of the failure was the piston rings, and the contact was given an estimate for the repair. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was 93,315.

Morning when we start out day, check engine light started flashing and car begin misfiring. The car doesnt ran fine after that.. I took car to Honda dealership and said the O-rings need replaced. They tried to get Honda to pay for repairs because they said it's the same issue that led to a class action lawsuit for 2011-2013 Honda Odyssey. In that case the "piston rings in certain cylinders may rotate and align, leading to engine oil consumption and spark plug fouling." Honda of America said they would not pay to fix my vehicle even though its the same issue.

One day I went to turn my car on and the check engine light came on with another light. Not sure what the other light was. My car was shaking to the point where I knew I shouldn't drive it. I called the dealership to see if it was drivable. They said it was not since the check engine light was flashing. I had it towed into the dealership. After an inspection they said it was an engine misfire and that cylinders 1-3 needed new piston rings. The spark plug was oil fouled as well. I had very low mileage on the vehicle. I had only 68,400 miles on the car. The repair was a little over $3200 to fix.

my engine sparkplugs keep getting oil fouled causing rapid deceleration of van and check engine light to turn on damaging plugs, this only happens in the cylinder head closet to firewall, this engine defect may be due to Honda VCM system. Honda effuses to acknowledge my complaint. the other problem is the transmission that shacks the van and slams as I come to a stop I started to complain at 26,000 miles but they would not fix it unless it failed completely at 95,000 when it got worse Honda said it was out of warranty.

I purchased new Honda Odyssey Van in Oct. 2013 (Model 2014) from Auto Nation Honda, Lewisville, TX. I have done services ever since. On 12/14/2021; I was driving on the highway. The check engine light came on along with other lights. The car was vibrating. I pulled the van on the side of 635 Hwy turned the van off, back on, and it persisted. Eventually van was taken to a workshop. I was told nearly a $6,000 repair bill due to piston rings and oil getting into the spark plugs. The van only has 67,980 miles on it. Upon further review, it appears that this is a known Honda issue with this engine (V6, automatic). There are service bulletins covering the 2011-13 model years. I am reading online that now newer model years are experiencing the same issue. It also reads like this issue will come back... I guess starting on the 2014 model years, Honda changed the piston rings. I don't believe this helped as I am seeing the same issue on my van. I contacted Auto Nation Honda dealer, and I was told I must pay out of my pocket. I think Honda has not fixed this issue for model 2014 Odyssey, manufactured in 09/2013.

I purchased this car used in 2018 from CarMax. I have done Honda dealer services ever since. Most recently in December 2021. On 4/6/22; I want to back out of my garage. The check engine light came on along with other lights. The car was vibrating. We turned the car off, back on, and it persisted. We eventually had it towed to a dealer. Yesterday, we were hit with nearly a $6,000 repair bill due to piston rings and oil getting into the spark plugs. The car only (approx) has 78, XXX miles on it. Upon further review, it appears that this is a known Honda issue with this engine (V6, automatic). There are service bulletins covering the 2011-13 model years. I am reading online that now newer model years are experiencing the same issue. It also reads like this issue will come back... I guess starting on the 2014 model years, Honda changed the piston rings. I don't believe this helped as I am seeing the same issue on my car. People have done the repair and it comes back. I contacted Honda corporate and I am waiting for a call back on a 'good will' case. I believe Honda is still using this engine.

I-??m writing about a concerning experience I had with our 2014 Honda Odyssey EX-L vehicle. We-??ve had this vehicle for about 5 years and haven-??t had any issues until recently. On Monday, June 14th approximately at 5:30pm PDT we were starting to accelerate on the freeway onramp when our Honda vehicle stayed in a low gear. I was unable to accelerate and eventually the dashboard lights started to flash and the HondaLink system restarted while this was occurring. The instrument panel then displayed the words -??Failure-?? and I proceed to the emergency shoulder of the freeway. Prior to this incident there were no indicators that there was an issue with the vehicle. After turning off the vehicle, I was no longer able to get the vehicle started and it had to be towed to our long-time auto repair shop. After they ran a diagnostic test and checked the vehicle, they said everything passed except for the battery which was still good prior to the incident. For safety, the battery was replaced and we drove the vehicle home on Tuesday, June 15th. The next day, June 16th, while my wife was running an errand and after returning to the car it turned over very -??sluggishly-??, the HondaLink system restarted again, and then it began losing electrical power as well. My wife didn-??t want to take any chances with having the vehicle shut down again while driving and ended up having it towed again to our mechanic. The auto shop ran another diagnostic and thoroughly checked the vehicle and couldn-??t find anything wrong right away. They had to do some additional troubleshooting and found that the alternator was defective even though the Honda diagnostics didn-??t report any issues with the alternator. The alternator was replaced and we haven-??t experienced any additional issues to date. This incident is extremally concerning as the outcome could have been worse or tragic if this would have occurred while driving at a higher rate of speed on the road or freeway.

I was pulling into a drive through on December 6, 2020. As I applied the brake (I drive with one foot - my right foot) with my right foot, the engine revved up and the van moved about 5 feet forward as I increased the brake pedal pressure. I then shifted into neutral. The engine went to red line. I pushed the power button. No one was injured, and the vehicle didn't touch anything as the drivethrough ahead of me was empty. The day before, the ldw and fcw fail light came on in the dashboard while my wife was driving. We have taken the van to the local Honda dealership for a checkout / diagnostics of what happened. Honda has opened a case on this for us: Case is 11754879. No pictures or video available, unfortunately, although I am checking with fadi's at 12360 westheimer road 77077.

I was driving 70mph on an interstate. The battery light came on. There was no immediate change in vehicle performance and there were no odors present so I continued driving for several minutes towards the next exit. About.5mi away from the exit, the ABS, fcw, ldw, and brake lights came on, the air conditioner and console turned off, and the automatic transmission disengaged. This prevented the vehicle from being able to accelerate. The entire vehicle essentially lost power. The local dealer diagnosed the issue as an oil leak in the spool valve that then destroyed the alternator and fried the battery. The manufacturer (Honda) recenty issued tsb 20-023 detailing the problem and repair procedure, but it was limited to the source of the leak, not any of the other components that were damaged. My understanding of the incident leads me to believe a fire could have broken out due to the location of the leak onto the other engine components.

(2014 Honda Odyssey ex-L). On fri, 02-21-2020, 3:47pm, I was slowing to stop at intersection. Before coming to complete stop, engine began to shudder, but did not completely stall/stop, and the mil indicator illuminated. Engine continued to shudder while idling at complete stop. I gently applied acceleration to 10-mph. Engine continued to shudder as I continued and stopped at another traffic light. Again I gently applied acceleration. The engine continued to shudder until I found a safe place to park and switched it off. The engine shuddered at a consistent level for a total of about 8-minutes. I called my local Honda service dept to ask about possible causes and if the vehicle was safe to drive. The service rep asked me about a previous repair noted on his computer for an issue the van had regarding the replacement of an oil sensor in October 2019, and if it was related. I told him I didn't know. Since he couldn't identify the problem, he advised me not to start the engine and drive because it could possibly cause more damage, and the vehicle was not safe to drive. Then I called roadside assistance and my van was taken to my Honda service dept. On the following Monday, a service rep called me with the diagnosis code P0303, which he said indicates that a misfire was detected in the #3 cylinder. The rep said that this issue allowed oil to pass by the multiple oil rings on the piston into the chamber and fouled the spark plug. He told me that this issue was not covered by the warranty. The service rep quoted $4,420 to repair obdii code P0303. I asked him if the malfunction could have been prevented. The service rep said that this problem is not a result of any driver action or lack of maintenance. He said that Honda is aware of this problem and I should call american Honda automobiles (800-999-1009).
