Why would both Check VSA System and Check Emissions System lights be on?

The VSA light could be related to the axle change if something was damaged or assembled improperly. Also, the VSA can affect emissions by reducing power output to correct for VSA errors. You will want to get it examined by a certified facility, which I'll put a link below for those in your area, but if you are still under warranty, take it in and have it diagnosed and repaired. http://repairpal.com/honda-within-10-miles-of-mission-viejo-california-92692
