A couple of nights back I was on the highway with ACC engaged and I proceeded to change lanes to pass slower traffic. ACC was still on and as I approached more slowing traffic in the passing lane, the ACC system failed to slow down resulting in me slamming on the brakes to avoid rear ending traffic.
I then notice that the ACC system is displaying an empty vehicle icon even though there are vehicles in front of me. Obviously this renders the system absolutely useless, and more importantly dangerous. I would think that If the system was not able to see vehicles in front, it would trigger some fail safe immediately and disable the system. It was not until the next stop/start cycle that the system triggered a warning about the vehicle assist systems and none of them were functionla. It then returned to normal operation several minutes later.
I have seen some others having the system trigger errors and stop functioning until the next power cycle, but have not seen instances of the system failing to detect vehicles ahead. I could have rear ended someone while trusting the ACC system to slow down as expected.
Anyone else have experience like this? It scared the
out of me.
