I have a 2015 Pilot Touring. 60K miles.
When I get on the gas (medium to heavy acceleration), I get a buzzing vibration felt through the steering wheel and gas pedal at exactly 40 mph. It lasts about a second and ends once the speed continues to increase past 45 mph. I do not feel it when accelerating slowly, nor do I feel it in neutral while revving the engine.
I am mechanically competent and do all my own repairs. This vehicle has been to the dealer under warranty and had both drive axles replaced and a PCM flash. TX fluid is brand new. All rotors/pads are brand new. All tires are brand new. All wheel bearing assemblies were just recently replaced. NOTE: This issue was occurring before all this and continues to occur after these repairs. I am also running the VCM muzzler.
I am scratching my head on this one guys.
