Owner Narrative

About mid-2025, Honda announced a warranty extension campaign (not a formal NHTSA recall) for: * 2013–2017 Honda Odyssey (and some Pilots) * Related to VCM (Variable Cylinder Management) What the problem was: * Piston rings wear prematurely * Oil gets past the rings → fouls spark plugs * Leads to: * Misfires (P0301–P0304) * Oil consumption * Rough running Mechanism: * Cylinder deactivation (VCM) → uneven temps → carbon buildup + ring sticking * Sometimes described loosely as a “piston/gasket issue,” even though it’s really piston rings + oil control What Honda did: * Extended powertrain warranty to: * 10 years / 150,000 miles * Covered repairs like: * Piston ring replacement * Spark plugs, etc. In March 2023 I had multiple piston ring failures costing me almost $4k to fix. I submitted a claim with receipts and the work was done at a dealership. Honda said I had all the appropriate paperwork and would get back to me in 6-9 weeks. That was 7 months ago
