On November 1, 2022, I was stranded on the road when the check-engine light came on. At Honda Muller of Gurnee, the dealer diagnosed misfires consistent with P0301\u2013P0304, explaining the underlying cause as piston ring function deterioration with sludge causing oil to foul the spark plugs. I was told my original warranty had expired only about six weeks earlier (on August 29, 2022). Coverage was denied and I was quoted over $6,000. Because I couldn\u2019t afford the repair, the dealer recommended replacing the spark plugs as a temporary measure only, stating this would not fix the underlying defect. I proceeded with that temporary measure. On November 11, 2022, American Honda formally acknowledged my concern in writing, confirming that Case #13455791 had been opened and escalated to a case manager in direct response to my diagnosis from November 1, 2022. Despite this acknowledgment, my repair request was denied. In 2025 I received Honda\u2019s warranty extension letter acknowledging coverage for this exact defect (including coverage through January 31, 2026). I returned to the dealer seeking repair based on my documented diagnosis, but repair was refused again because the codes were not present that day (the condition is intermittent). This defect affects drivability and safety (loss of power/hesitation and reduced ability to merge or cross traffic). I am asking NHTSA to record this complaint and consider action so that owners with documented prior diagnoses \u2014 especially those recognized by Honda corporate \u2014 are not refused repairs simply because an intermittent defect isn\u2019t active at the exact moment of inspection.
