On July 11, 2026, while driving, the vehicle suddenly experienced multiple system failures. The dashboard illuminated with numerous warning lights, including a flashing check engine light, indicating multiple system malfunctions. The vehicle was towed to the dealer due to the severity of the issue. It is currently at the dealership for inspection and diagnosis. I have not yet received a diagnosis or confirmation of the failed component(s) from the dealer. No warning lights, messages, or symptoms appeared prior to the sudden failure. The abrupt illumination of multiple warning lights while driving created a significant safety concern regarding the reliability of critical vehicle systems.
The vehicles trouble screen on the dash summoned us to engine problems. Do not drive over 40 and notify your dealer immediately. We did so, Honda America sent a tow truck picked up the vehicle and sent it to the dealer. The next day the dealer contacted us and said they found excessive carbon on all the engine valves and all 6 cylinders were miss firing. The dealer gave us a loaner, after several phone conversations with the dealer and Honda America they gave us the vehicle back. They walnut blasted the valves to clean the carbon and Honda America is investigating the issue. This vehicle is a 2026 Passport with 24000 miles.
Our 2026 Honda Passport tse suddenly stalled twice in active traffic intersections in albuquerque, nm under acceleration and during a left turn, causing a sudden loss of motive power and a severe safety hazard and a potentially life threatening situation. Telemetry logs from an aftermarket gps device installed in my vehicle captured a catastrophic voltage drop down to 10. 886v during the incident, which electrically blinded the ecu and prevented the vehicle from storing a diagnostic trouble code. The vehicle was taken to garcia Honda in albuquerque, nm who documented the symptoms ('loss of power on accel,' 'hesitates and jerks') but released the vehicle unfixed because no digital codes were present. The vehicle is currently grounded as unsafe to drive. American Honda corporate case number: [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The engine suffered a failure of the connecting rod bearings and wrist pin or pins. It necessitated a short block replacement.
Today, while backing from my driveway into our residential street, I came to a complete stop and placed the vehicle's transmission from reverse to drive and when doing so, the vehicle shut itself off, put itself into park and engaged the parking brake. I was able to re-start the vehicle and it operated as usual. We have an appointment scheduled with our local Honda dealership on 05/19/25 to inspect the vehicle.
