We are reporting a safety concern on the Honda Odyssey that Honda Corporation is aware of on the 2016 Honda Odyssey. They have a defect in the Piston Rings on the Engine. This engine design on the 2016 engine is the same where a recall was called on older versions of the Odyssey and other Honda vehicles. They have not included the 2016 as they say that they haven't had many cases of this version having the problem. With a quick search of the web you will find many people who are reporting or talking about piston ring issues, misfire and spark plug problems on the 2016 Odyssey. They are then asking customers to spend between $3 and $5 to fix this problem in the engine. Which is a known engineering defect! I have kept up with my oil changes and had a well maintained vehicle rating on CarFax. We are reporting the problem to you as when this happened it was extremely dangerous to drive the van. We were stopped at a red light just stopped and the engine was idling when all of a sudden the van started shaking. No sign of a problem prior to this happening. Then we looked and no lights were on but as soon as we started to drive the check engine light came on. We drove the van the couple of miles home as it was a Sunday and the engine had no pick up and go. Pulling into traffic or turning was a danger. This is a danger to not only us in the van but others around us who are not aware of a problem. We drove the van to the dealership on Monday morning. They said that it had caused a bad spark plug and they could clean the area and we may get 5000 to 20000 more miles but that recommended that we would some point need to spend the $4600 to fix the piston rings as well. We did the spark plug repair and they returned the van to us. It still seemed sluggish but we quickly realized that it was having major problems. This is a danger to people in the vans as well as others on the road. Honda should be required to cover the cost of piston ring issues on all years.

engine in this vehicle keeps having a misfire in Cylinder 2 (when looking at engine in car, it is the back side, 2nd from the left) caused by eco mode per honda techs. The piston ring needs replaced per tech and car is 2 model years outside the warranty for this issue that is still going on. its a common issue and is still occurring even is newer models according to the 2 local dealerships.

The engine. I have a 2016 Honda Odyssey. All scheduled maintenance has always been done on this vehicle. I have all the documentation. And I mean it has been babied. It has 110,000 miles. Driving one morning last week and the car just seized up. No warning. No previous warning light. Had it towed to the dealership. The Variable Cylinder Management system had allowed a build up of gunk in the engine. Need an engine rebuild.$5600. Honda just had a recall for cars of the same model manufactured before 2014 for the same issue. As for safety having your engine seize up on the highway is dangerous.

The spool valve had a complete seal failure leaking oil onto the alternator causing the alternator to fail. As result the entire electrical system failed, shutting off all propulsion of the van. This occurred while the vehicle was in the high speed left lane on [XXX] @ the [XXX] exit. I had to coast the vehicle across two lanes of 75 mph traffic, cars and large tracker trailers. I was passed by several cars and tracker trailer while coasting across the two lanes of traffic as there was no shoulder on the left side of [XXX]. There were no warning lights prior to the event. American Honda Motor Co. issued Service Bulletin [XXX] on [XXX] to Honda Dealers/Service about the potential for the spool valve casket to leak and fail so that Honda could check for this failure and replace the defective spool valve. The service bulletin covers five (5) different Models and for some Models six (6) model years. The part number identified is 15810-R70-A04, Front Rocker Arm Oil Control Valve (Spool Valve). The correction action is to inspect the front rocker arm oil control valve for leaks and, if needed replace it. The possible causes are the gasket on the front rocker arm oil control valve has deteriorated or the gasket groove is out of SPECIFICATION. Service personnel at Jeff Wyler Honda, 949 Burlington Pike Florence KY 41042, admitted to replacing this spool valve on my Honda Odyssey model several times a month. They admitted that the failure of the spool valve seal can leak oil on to the alternator causing the alternator to fail causing a complete loss of the electrical system and propulsion, seen reports of complete engine fires due to the spool valve gasket failure, noted that the the service bulletin was not attached to my vehicle VIN as did Honda of Jackson 1408 U.S. Highway 45 ByPass Jackson TN 38305. Because America Honda Motor Co. failed to attached the service bulletin to my VIN, my vehicle was not inspected properly for this safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

The passenger side second row seat will not lock. It has been diagnosed by a Honda dealer that the seat back frame part number 81326-TK-A22 needs replaced. A recall has been made for the drivers side second row seat in bulletin 18-026. The part number is 81726-TK8-A22. It is the seat frame as well. Honda said they would assist me in paying 1/3 of the bill, but I was responsible for the remainder of the balance. But I see it that there was a seat frame issue with the drivers side second row seat and now I also have a seat frame malfunction on the passenger side second row. I believe they should cover the passenger side as well because of it being an important safety issue.

Pistons Ring premature wear . Car only have 100000 miles on odometer but during 100000 mile service. Honda dealer find abnormal wear of piston ring due to which they suspect leak in combustion chamber which can cause further issue . I bought the Odyssey to last longer , did not expect to do major repairs on only 100k miles and unfortunately that's not the case. Now, I need to make a decision. Pay the 4k get it fixed or keep it as is.

My vehicle problems started on February 6, 2024 while my daughter was driving back to her house. My 2016 Honda Odyssey EXL started shaking violently at 55 - 60 mph. Upon towing my vehicle to have my certified mechanic to check it out, check engine light was on with codes and misfires. He determined that the variable timing valve solenoid was bad. He replaced faulty part as well as both oil pressure switches and it then came up with check engine light, as well as FCW, LDW, & anti-skid warning lights!? It also had a couple different codes. He then replace other variable timing valve solenoid on front of the engine. After taking vehicle to dealership, to get diagnosed, they suggested several repairs totaling over $3800, which none could insure that it would fix problem (2 of their suggestions were already done by my mechanic). Taking dealership suggestions, my mechanic replaced spark plugs and coil boots, adjusted valves which were fairly close, along with new valve cover gaskets. Now my vehicle runs better but has this engine knock when engine switches from ECO mode to regular full cylinders. Asked dealership about checking/reprogramming control module, but they won't do it!? Any suggestions??? Considering purchasing bypass kit even though I will lose gas mileage
