2026 Honda Passport Engine Problems

“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.”

“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.
