+1 on checking the final drive oil level, mine was 1.5 to 2.0 oz's low. Told my dealer about it and it went in one ear and out the other. The 2015's have a bastard size hex on the fill plug however and a 17mm wrench is too loose. I had a friend mill out a 16mm 6-point box wrench to fit the plug, perfect now. Also, I topped it off with the recommended hypoid oil, Pro Honda 80W-90 purchased from the dealer.
