The vehicle is equipped with a vehicle collision warning device that is intended to warn the driver of a vehicle in front that you are to close to and closing range without braking. On about 1/2 dozen occasions the vehicle's early detection system has engaged without any vehicles in front. These occurrences seem to be on days when it is raining and their are reflections off the road, or very sunny days (again causing reflections). The flashing light, loud alarm, and interruption with regular audio is very jarring (scary). On one occasion I applied my brakes very hard because of the alarm (but there was no car in front) - this almost caused the car behind to hit me. The system should be disengaged to prevent a false/positive alarm. I have taken it for service and contacted General Motors without results.

Forward collision avoidance system inappropriate activation on several occasions at different locations. There were no other vehicle in front. There were three beeps/red light flash on windshield. The cruise control would deactivate and car would decelerate by three to five mile. The tail lamps are not activated to warn drivers following. This is my second complaint the dealer solution is to turn off the feature. It work when it should the inappropriate activation is a nuisance.

Experience on multiple occasions the forward collision avoidance activation of a flashing a red light from dash into the front windshield and sounding an alarm with three or four beeps. Referring to this as phantom braking activated by the forward collision avoidance system causing autonomous brake activation and the cruise control disengagement. It is unknown if the activation of brake lamps occur I hope they work when this happen. My service manager suggestion is to deactivate feature.
