NHTSA Complaint #11563505 — 2015 HONDA ODYSSEY

Honda's variable cylinder management (VCM) system puts inordinate wear on engine cylinders that causes the vehicle to shake and misfire and eventually shut down the engine. It causes spark plug and cylinder coil failures and cylinder damage. This is not due to age, misuse or lack of proper maintenance. The VCM causes engine build up as a normal course of action. This is a known issue that Honda has never communicated to owners of these vehicles. Model years 2011-2013 had the same issue. Honda has offered no recourse, or even communication, to owners of 2014-2017 Odysseys with the exact same VCM (VCM2) mechanism and the same wear and tear on the engine. You can read more about the issues these vehicles have and how common this is here: [XXX] Honda dealerships will replace your cylinder rings (at a HIGH cost) but this does not fix or prevent the issue from recurring. Our vehicle had this work done at 77K miles, but it does not stop the VCM from causing build up and malfunctioning again in the future. Families like ours buy these vans because they are supposed to have reliable engines, and be safe for their families. They sold 450K model year 2014-2017 Honda Odysseys and this effects EVERY one of them on the road today. This is a consumer issue AND a safety issue.
