NHTSA Complaint #11683318 — 2013 HONDA ODYSSEY

Vehicle diagnosed with Code P0303 on 8/18/25. Per the dealer (Big Star Honda, Houston TX), "...Examination found the number three cylinder piston rings on cylinder #3 rotated and aligned, which caused spark plug to foul out." In October 2020, American Honda issued SB 13-081 for this known issue and to settle a class action lawsuit. In July 2025 American Honda issued SB 25-061 extending the warranty for 2013–17 Odysseys through January 31, 2026. Honda is denying covering repairs stating that it does not apply to my specific VIN. The VIN is inconsequential if the new SB simply states "2013-2017". All vehicles, regardless of VIN should be repaired given that the problem has been diagnosed as identified in both the 2020 and 2025 SBs. Absent this and a listing in the SB of all applicable VINs, Honda can always indicate that a VIN isn't covered to avoid covering the repair costs, even though it should be. Repair at Big Star was declined to pursue coverage of the repair costs further with American Honda.
