While using the cruise control, vehicle will automatically slam on the brakes without reason. This typically occurs on highway where vehicle will automatically brake reducing speed dramatically. Vehicle will go from 70mph to 55 MPH in a few seconds causing the vehicles behind to have to brake fast to avoid collision. Acura has worked on vehicle 4 times and claims they cannot fix the system. I was told to hold my foot over the accelerator to increase speed when this happens. They also told me that they are very aware of this problem but offered no correction for this unsafe condition. It has happened at least 100 times. Vehicle is 4 years old with 7,000 miles.

I was driving on a highway with the automatic cruise control (acc) enabled and set at 68 MPH. Without touching the pedal or controls, the cruise speed setting suddenly jumped to 90 MPH and my car rapidly accelerated to reach that speed. Fortunately, there was no one in front of me and I was able to take control of the car and disable cruise control.
