We have a 2016 Odyssey that developed the same engine issue r/t the VCM/ECO at 140k miles. The dealer quoted us $5k to replace the piston rings for 3 cylinders on one side because they are done as a kit. We found a local mechanic who is Honda certified who did it for $3k and installed a muzzle to disable the VCM, so it doesn't happen again. He said he does this repair a couple of times a month on these vehicles. Needless to say our faith in Honda, which we have bought from for the last 25 years, is lost. Time to buy from a different brand!
