2016 Honda Odyssey

Local mechanic informed me that there there is a defect in the piston causing oil to leak in and ruin the piston and spark plugs. This is fouling up the spark plugs, which are covered in oil. Temporarily he said to replace the spark plug. If that does work, he recommended a valve cover replacement. And if that still doesn't work to replace the engine. This was on cylinder number 1. This also happened last year with cylinder number 3. The engine light comes on and the vehicle starts shaking and causing engine misfiring. The oil was changed approximately 1 week ago when cylinder 1 was having issues. Yes, this vehicle is currently available for inspection. This could be a safety issue due to engine failure while driving on a busy road. This van was purchased used in 2018 with 1 previous owner. This problem has been confirmed by a repair shop.

The engine failed while driving on the highway. All lights flashed on dashboard and loss of power to the vehicle. There were no prior check engine lights on before it activated and started flashing. Piston 3 failure that had to be replaced (pistons 1-3). Engine had been burning oil but no low oil indication had been illuminated nor was car due for an oil change. Spark plugs and ignition coil had been replaced approx. a year prior due to similar but less severe incident of check engine light coming on and misfiring engine. Six months after the pistons were replaced, the oil pressure switches were diagnosed as faulty and needed replacement due to a false low oil pressure reading.

Alex from Germaine Honda informed us “There is a defect in the piston causing oil to leak in and ruin the piston and spark plugs. The only option is to replace the engine. There was a light that came on indicating oil was low a few weeks before it symptoms started however there was plenty of oil when checked and it was not time for oil change per record. While driving one day car started shaking and engine misfire. Multiple engine and system warning lights came on. In 2022, we had a similar issue with piston rings out of alignment and spark plugs fouled with oil that resulted in costly repairs. Yes this vehicle is currently available for inspection. This could be a safety issue due to engine failure while driving on a busy road. This van was purchased used in 2018 with 2+ previous owners. This problem has been confirmed by a honda dealer.

Just before hitting 100k miles and planning for timing belt maintenance, I got hit with the well known VCM V6 engine issue. Fix for 7k from my own pocket? No. I just replaced spark plugs and as the advisor suggested I have to install the VCM Muzzler (from after market, as Honda don't do this) to deactivate ECO mode in order to prevent future damage. I hope NHTSA will force Honda to recognize this is their fault (poor design) and fix this on a big recall, otherwise I'll participate in a lawsuit when that will occur for this lemon car.

Brought brand new in 2016, our Honda odyssey has been well maintained by the dealer. Just hit 148k miles, and the check engine light started flashing - took it straight to the dealer. Said that we need the engine rebuilt for $4k replacing spark plugs and cylinders. Upon further research, this is a known issue with the VCM motors by Honda, and had a class action lawsuit for previous years of the odyssey- but when the lawsuit was done, our years had not reached over 100k miles yet. Honda service is saying there is now a software update to prevent this from happening again, when we replace cylinders, but why is this happening when we have brought it to the dealer for all maintenance and if there was a preventative fix for this, why wasn’t it done before damage was done to the engine? We are being given the run around, was offered $500 to buy our van, or pay the $4k+ to fix. Honda corporate is just going in circles not giving us answers and why this is being allowed to happen. This is my 4th Honda - 2nd to buy brand new- and this is making me question loyalty to the brand.

The contact owns a 2016 Honda Odyssey. The contact stated while driving 65 MPH and depressing the accelerator pedal to pass another vehicle, the vehicle hesitated to respond and the engine sputtered. Additionally, the contact stated while driving from a complete stop the failure recurred. There was no warning light illuminated. The contact stated that the failure had been recurring while driving. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was notified of the failure and referred the contact to the dealer for diagnostic testing. The failure mileage was approximately 76,000.

My engine's check-engine light began flashing, and it turned out to be misfiring on one of the cylinders. The dealer disassembled the cylinder and found that it was filled with oil, and the piston seals had failed for cylinders 1-3, and they are now saying it will be a $4K rebuild of the seals. Looking online, this appears to be a VERY common problem with these V6 Honda engines that have VCM on them; this is the same VCM system for which Honda had to settle a class-action lawsuit for this exact issue happening to thousands of engines. They only included vehicles through the 2013 model year, but continued to use the VCM system in later engines; there are thousands of reports of this same issue continuing to occur.

The engine failed and required a complete ring/piston replacement at a cost of $5,670,52 with only 135,946 miles. I purchased the vehicle new and had it serviced at Honda dealerships throughout its life. These vehicles are used by families and many older citizens because of their ease of access and advertised reliability. Such an unexpected expense should be covered by Honda. This ring/piston replacement has been a problem in earlier modules and was covered by Honda.
