An Insurance Institute for Highway Safety Top Safety Pick in 2009, the MDX doesn't retain that title for 2010 because it hasn't undergone the organization's new roof-strength test. It does still get top overall scores of Good in the IIHS' front, side and rear crash tests.
A collision-avoidance system is optional. It uses radar to determine the location of a vehicle in front of the MDX and alerts the driver with sounds and lights if a collision may occur. If the driver disregards the warning, the system will tug at the driver's seat belt and lightly brake the MDX. If no action is taken and the system deems a collision inevitable, it will tighten the front seat belts and apply the brakes hard to lower the impact speed. You must select the most expensive Advance Package to get both the collision-avoidance system and blind-spot monitoring.
A base MDX starts at $42,230. Adding navigation as part of the Technology Package brings the price to $45,905, but I think that price is well-justified. Add the rear entertainment system, and the price increases to $47,805. You can't add the rear entertainment system without also getting the Technology Package.
