NHTSA Complaint #11654987 — 2013 HONDA ODYSSEY

My 2013 Honda Odyssey is experiencing a serious engine malfunction related to excessive oil consumption and spark plug fouling. On [XXX], the Check Engine Light came on and the vehicle began shaking. A diagnostic inspection at a Honda dealership revealed DTC P0301 (Cylinder 1 Misfire). Three spark plugs in Bank 1 were heavily fouled with oil. The technician recommended piston ring replacement, noting that oil had leaked into the combustion chamber. This issue is consistent with well-known engine problems associated with Honda's VCM (Variable Cylinder Management) system. TSBs such as A13-081 and 11-033 have addressed similar issues in the past, but my vehicle is no longer covered under the extended warranty. I am a low-income international student currently living in the U.S. with my family. This defect creates financial hardship and safety concern. I respectfully request that NHTSA investigate this matter as a safety-related engine defect and urge the manufacturer to offer proper recall support. - Mileage at most recent diagnosis: 116,520 miles - Current mileage: 117,300 miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
