2015 Honda Odyssey problems

“Vehicle Information:Year/Make/Model: 2015 Honda Odyssey EX-L VIN: [XXX] Mileage: Approximately 45, 200 miles Component / Defect: Engine Oil Leak leading to Alternator Failure (Front Spool Valve / Valve Cover Gasket Leak onto Alternator) Summary of Incident and Service History: My car overheated and would not start on several occasions over the last year and a half starting in July 2025, leaving me stranded and requiring it to be towed. My car has been in service at the dealer multiple times for approximately 2 weeks each time. Oil Leak and Alternator Hazard: The vehicle experienced engine oil leaking directly onto/into the alternator. According to communications from Honda service personnel ([XXX]), oil leaking from the front spool valve and valve cover gaskets penetrates the alternator, causing component failure. The dealership explicitly warned that failure to complete these repairs would result in repeated alternator failure. XXX Service: The vehicle was brought in for diagnostic work and repairs at Brickell Honda Performed services included diagnostic procedures, engine oil & filter replacement, radiator fan motor replacement, A/C condenser fan motor…”

“Approximately 7 months ago, my 2015 Honda Odyssey experienced an engine misfire with code P0302 (cylinder 2). All spark plugs were replaced at that time and the issue appeared resolved. However, the misfire has now returned with the check engine light on, again indicating cylinder misfire. The vehicle only has 71,000 miles on it, which makes this recurring issue particularly concerning. Based on my research, this appears to be a known defect related to Honda’s Variable Cylinder Management (VCM) system causing excessive oil consumption and spark plug fouling — an issue documented across 2013–2017 Odyssey vehicles and addressed under Honda Service Bulletin 25-061. I am requesting this complaint be on record and urge NHTSA to investigate this as a safety-related defect.””

“American Honda Motor Co., Inc. issued an official Warranty Extension in July 2025 covering engine misfires from piston ring deterioration (DTCs P0301-P0304) on 2013-15 Pilot and 2013-17 Odyssey vehicles. My 2015 Honda Odyssey (VIN: [XXX]) experienced this exact defect, resulting in severe engine misfires and secondary alternator failure caused directly by engine fluid saturation leaking onto it from the primary defect. I paid $5,275.80 for repairs prior to campaign awareness (Invoices XXX and XXX). I submitted complete reimbursement documentation on January 31, 2026. Honda has withheld my funds for 178 days (which is 122 days past their promised 8 week deadline) while corporate customer care agents falsely claim payment is “approved but pending final management sign- off.” I have called 11 times and corporate managers who are never available HAVE NEVER returned my calls like the representative with Honda I've spoken with each time assures. This deliberate delay subverts federal safety campaign integrity and artificially manages liability exposure. Request immediate enforcement action for an ongoing corporate warranty evasion pattern.”

“2015 Honda Odyssey Touring Elite, VIN [XXX]. Vehicle was involved in a frontal collision on XXX. The driver's frontal airbag did not deploy. During the impact, I was thrown forward and struck the steering wheel. Additionally, a side/sliding door opened during the collision. The door was closed before the collision. I am concerned about possible failures of the supplemental restraint system and door-latching system.”
