NHTSA Complaint #11676053 — 2015 HONDA ODYSSEY

My vehicle has a know issue with Honda Corporate with the variable cylinder management that has lead to 7 miss fires in 4 years. The frequent and excessive miss fires are caused by carbon and oil leaking through the piston rings. Honda has attempted to repair the piston rings but that repair was a fail. I’ve experienced a miss fire after the repair and now require another change to my spark plugs recommended by Honda. I filed a reimbursement case with Honda and was notified they will not resolve the issue or reimburse me for the excessive miss fires, spark plug and coils replaced due to their faulty know engine defect. They announced in July 2025 that they were extending the warranty to cover repairs related to engine misfires (DTCs P0301 through P0304) and will last for 10 years from the original purchase date or 150,000 miles. However they have denied my reimbursement after sending proof of miss fire work and payment.
