Description of the problem | While using the acc function and setting forward distance at any length the problem is that when the car in front of you slows, stops,,or turns my vehicle will brake on its own. However, while braking during the mentioned operation the big problem is that the brake lights do not illuminate. I have had several close calls with someone nearly running into the back of my vehicle during the use of the adaptive cruise control (acc). This can be extremely dangerous if you are now fully aware of this problem. This should have been addressed during the acc hazardous examination phase. A very simple fix would be to install an i/p switch in the brake line at the master cylinder so that the pressure from the acc applying the brakes sends the pneumatic signal to an electrical signal that lights up the brake lights. This problem should absolutely have been caught and addressed during the design phase. I found out when i asked a service manager about it and he said the lights do not come on. He also said they know about it. |
