Consumer Description

On freeway in traffic, autopilot is enabled. Vehicle is running perfectly fine in start stop traffic slowing down and speeding up as needed. Traffic starts to clear up, and as vehicle speeds up, there is a sudden slowdown again. Instead of braking/slowing down, autopilot turns off without an additional audible alarm (just the standard sound for turning off autopilot), instead the forward collision warning alert goes off. Able to brake in time to prevent accident.
