NHTSA Complaint #11580633 — 2018 HONDA ODYSSEY

At 60 mph, the fuel injectors failed on cylinder 1/2/3 (known issue based on TSB [XXX]). The vehicle produced various error codes but did not go into limp mode. We proceeded to the nearest exit on the highway to safely pull off. The engine shortly after turned on limp mode as we neared the exit. We heard an audible ping noise and the engine power changed (could still keep the vehicle moving but shaking in the steering wheel). We were on a straight path of road so the steering wheel shaking was manageable. We had the vehicle towed to nearest Honda Dealership and they completed the TSB putting in new injectors. The fault codes cleared on cylinder 1 & 2 but not 3. They performed compression test and assessed dead cylinder requiring new engine replacement. Technician also noted that #3 injector had locked open and spark plug was soaked with fuel from flooding the engine cylinder. I escalated to Honda Corporate (case # [XXX]) and they looked into the matter believing it wasn't that severe. After 1 month, they closed the claim at the regional manager level, with no earnest money, and said we were on our own for an engine with 74k miles since it was out of 60k warranty. I towed the car to my private certified mechanic (who had done all the oil changes since purchase at 34k miles). He checked with borescope and cylinder wasn't moving while crank turning. He has diagnosed broken piston rod and looking for used engine to try and replace. Honda Asheboro quoted $6,400 for repair. We believe that #3 cylinder hydro-locked when ECU turned off injector and spark plug but couldn't closed the injector properly (known debris in fuel system) causing the piston rod to break and luckily not drop the piston into the crankcase. Car is sitting idle waiting for repair or further review. Will be taking Honda Corporate to small claims court in Stanly County, NC. Other known issues for this model/year is fuel pump and piston bearings (both also TSB's and not recalls). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM
