2016 Honda Odyssey

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

While driving the engine started to run rough and the vehicle started to decelerate. The check engine light and the traction control light came on. I let up on the gas pedal, the van continued to run rough. I made it home and the next day took the van to a mechanic, he told me that he observed oil fouling on the #3 spark plug, consistent with worn piston rings. The van is a 2016 Honda Odyssey with 91,000 miles.

I have had the same issue now twice with my vehicle. The first repair was done in 2020 and covered by Honda under warranty. They repaired Cylinder Block-Piston Rings misfiring. It was I believe about a $3,500 repair when covered under warranty. I now have the same thing happening again. I took it in to Honda for diagnostic test and and i have the need for immediate attention to repair-end of October, 2023. I also already had labor service April 11, 2023 and had a code PO303 cylinder#3 misfire, swapped plugs 3 & 5. Spark plugs causing issues. Again the beginning of October I had to take my vehicle in AGAIN for spark plugs and misfiring. Had the spark plugs changed twice this year. And already had a MAJOR repair for the piston rings on this same vehicle. This should not be happening AGAIN. When my car needed the plugs changed in October 2023 my check engine light came on and was flashing and driving rough. I had to towed to shop to get looked at.

The contact owns a 2016 Honda Odyssey. The contact stated that the check engine warning light was illuminated. The vehicle was taken to a dealer and the contact was later informed that the piston ring on cylinder #3 was defective. The manufacturer was notified of the failure but offered no assistance. The vehicle had been repaired. The failure mileage was approximately 48,000.

My wife experienced a sudden loss of power and a very rough running engine at interstate speeds. The check engine light as well as the FSW lights indicated problems with the engine. We brought the vehicle into a Honda dealership for diagnosis. The technician observed an oil soaked spark plug in the #3 cylinder which caused the issue. There were no lights associated with the issue until the sudden loss of power. This dramatic loss of power put her at risk as she limped to a safe area. Honda not only recommends replacing the plug but also all the rings on the rear three cylinders to make the vehicle safe. This is the second time this same vehicle has experienced the same failure and it appears to be an issue with the VCM system on this model. First instance was around 60k and now at 120k.

My car technician found that my car has leaking problems, and is burning engine oil for a long time which means the engine oil leaking from the engine that might cause fire or damage engine and cause serious engine failure and this is a serious safety concern. I heard this is a common problem for Honda cars. Please advise to recall the vehicles with this problem. Thank you very much.

Per Honda dealership technician: oil seeping into cylinders 1-3 when VCM system is on. Spark plugs are fouled up and causing misfires on engine. Scoring on cylinder 2 also likely due to VCM issues requires engine block replacement. The above engine issues are the reason for blinking check engine light, traction control disabled light, and forward collision warning disabled light to all be on. These ultimately are occasionally causing stuttering/shuddering of the engine during acceleration. While trying to accelerate on an freeway on-ramp the engine appeared to hit a rev limiter at ~4,000 RPMs and wouldn't up-shift to the next gear while doing ~45 MPH with other vehicles behind us also trying to accelerate. Had to let off the gas and gently accelerate over a longer distance/time keeping RPMs low and was able to accelerate to 75 MPH speed limit after merging onto freeway. Vehicle is otherwise in good condition and has maintenance attended to regularly.

The contact owns a 2016 Honda Odyssey. The contact stated while driving 45 MPH, the vehicle started shuddering and was running rough. The check engine warning light and the traction control warning light were illuminated. The contact stated that the failure had been recurring while driving. The vehicle was taken to an independent mechanic, where it was diagnosed that there was oil intrusion on the spark plugs, which caused a misfire. The mechanic replaced the spark plugs and added a fuel additive to the vehicle; however, the failure persisted. The dealer was not notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the dealer for diagnostic testing. The failure mileage was approximately 68,000.
