For enhanced safety, the front shoulder belts of the GMC Acadia are height-adjustable, and the middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Acura MDX doesn’t offer comfort guides on its middle seat belts.

The Acadia has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The MDX doesn’t offer front seat center airbags.

When descending a steep, off-road slope, the Acadia AT4’s standard Hill Descent Control allows you to creep down safely. The MDX doesn’t offer Hill Descent Control.

There are over 6 times as many GMC dealers as there are Acura dealers, which makes it much easier should you ever need service under the Acadia’s warranty.

A hardened steel chain, with no maintenance needs, drives the camshafts in the Acadia’s engine. A rubber cam drive belt that needs periodic replacement drives the MDX’s camshafts. If the MDX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

The Acadia stops shorter than the MDX:

The GMC Acadia’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Acura MDX only has 5 wheel lugs per wheel.

The Acadia offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road.

The MDX prevents the driver from operating the other windows just as it does the other passengers.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Acadia’s available exterior PIN entry system. The MDX doesn’t offer an exterior PIN entry system, and its AcuraLink can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

The Acadia SLT/AT4/Denali’s standard rear view mirror and optional side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The MDX has an automatic rear view mirror, but its side mirrors don’t dim.
