NHTSA Complaint #11653687 — 2020 HONDA PILOT

•What component or system failed or malfunctioned, and is it available for inspection upon request? The “smart” control module, part# 38320-TG7-L112-M1 was removed and inspected; obvious incomplete conformation coverage was discovered along with significant dendritic growth on an uncovered IC. Proper cleaning of the board alleviated the issue – for the time being at any rate. I am including pictures of the board and growth that clearly show this defect and its related consequences, but I can provide the part for inspection if it’s feasible timewise and if I haven’t sold the vehicle by that point. •How was your safety or the safety of others put at risk? The vehicle was rendered completely and utterly inoperable by this condition and additionally necessitated the removal of the battery to keep the car alarm from triggering randomly. If this condition manifests itself at the wrong time it could easily create a dangerous situation for myself, my family and others. •Has the problem been reproduced or confirmed by a dealer or independent service center? The diagnosis, research, documentation and associated repair were performed by an independent service technician. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This problem was reported to Honda USA in late March of 2025; no acceptable recourse was provided or offered. •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. On Friday March 21st at approx. 6PM, the car alarm was triggered with no interaction whatsoever after the vehicle had sat for several hours. After disconnecting the battery for over an hour the problem immediately returned upon reconnection along with flashing dash & interior lights and clicking relays and/or components.
