This is first summer for this car and I notice when AC in on and car is not moving there is some kind of moaning loud noise coming from the engine. I took my car to the dealer from where I purchased this vehicle. I was informed that Honda Motors is aware about this issue in 2012 Pilot.
Till the date Honda Motors did not solve this problem. Please make a note that the noise is very loud when AC is on and car is not moving. This noise is very annoying. This loud noise giving me migraine every day. DO NOT BUY THIS VEHICLE UNTIL HONDA SOLVE THIS PROBLEM.
Old post, but this problem was fixed on my Pilot with TB 13-016.
The power steering pump operates on a similar frequency to the a/c compressor, creating a harmonic frequency noise.
TB 13-016 directs the replacement of the power steering pump and pump bracket.
Completely eliminated the noise on my car.
