Called my dealer as service B123 light came on at 52500 miles.I was quoted $650 for the service and dealer is 22 miles away. Called local Honda dealer and they charged me $400 with discount coupon from their web sight. Only six miles from my house and car was done in 2 hours. Skipped the filters and tire rotation as tires are new and I can change filters myself. What a rip off from Acura!!!! My Acura MDX is a 2016 Advance with the 9 speed tranny.
