Traveling 65 mph on a freeway with adaptive cruise control (acc) engaged, vehicle suddenly brakes hard on its own for no apparent reason; dropping 10 mph in a heartbeat. The vehicle did not produce a collision warning message on the dash. The cars in front on me were well beyond the longest 4 bar range of the acc so it was not detecting and locked onto a car in front of me. There were no cars on either side, no car crossing in front of me and the road was flat with no obstacles. Fortunately, the car behind me was not tailgating as the sudden deceleration could have caused a rear end collision. Sudden deceleration has happened twice during the six weeks I've owned this vehicle. I've also noticed that the acc is inconsistent, often sluggish, in responding to the speed of traffic when it is detecting a car in front of me; creating additional hazard concerns for the driver...updated 05-27-15 updated 8/28/2017

Our vehicle is an Acura MDX 2014 with the advance package. One feature of the package is adaptive cruise control which aims to keep the vehicle moving at a steady rate and at a set distance from any vehicle in front of it. On several occasions, when vehicles in front of ours slows down or a vehicle merges from another lane in front of us (even transiently), instead of gradually braking and speeding up, the Acura performs sudden deceleration with hard braking even if the vehicle in front is doing the same speed or going only slightly slower. After the hard braking starts, if the vehicle in front speeds up, our vehicle does not recover and start to accelerate again. I have a pregnant wife who is the main driver of the car and I am concerned that this problem will cause her to be rear-ended.
