the dealer experience in Canada is just horrible. People are running from Honda because of this. Diagnostic fee's for all warranty / blame the customer. It's infuriating. Glad you had the extended warranty and kept the gas receipts. I can't believe they balked and pushed back at you for what is a known problem with this engine in all models. Are you in GTA area ?Just had my injectors replaced under extended warranty. Truck was in the dealership 4 times in the last 3 months for the same issue. Dealer kept resetting the computer stating I use bad gas even though I told them otherwise. On my fourth trip to the dealer I brought every receipt for fuel since day 1 I took ownership of the new truck. I keep logs of KM's driven per day and the only place I get fuel is Shell and it's premium without Ethanol.
I had to help the service manger close his mouth when he looked over my records. They finally replaced O2 Sensors, Injectors, Cat converter and it seems better. My RPM's fluctuate like others however I believe that's related to the transmission fluid needing to be changed.
I have 73,000 KM on the truck which I bought brand new and I can't believe how frustrating it's been at the dealer. When I bought the extended warranty I was thinking I wasted money; but thankfully I'm covered to 120KM.....Thinking I need to pay to extended to 200KM!
