Automatic System Braking Problems of GMC Acadia

The automatic braking system activates when there is no danger of collision or impact. During heavy rain, backing out of a parking space, with no hazard activating the emergency braking system near your vehicle, the emergency braking system will activate every 2-3 feet driven- sometimes occurring 6-8 times when trying to back out of space. This is a safety hazard because you’re left sitting in a roadway with no control over vehicle. Your chances of being hit by oncoming traffic, because your vehicle stops itself over and over, is high. Not only is the automatic braking jarring, you have to sit in oncoming traffic while the emergency parking brake releases. The emergency braking system will also activate without cause when backing down a hill, even on a sunny and clear day. This poses a danger when trying to parallel park, on a hill, in busy traffic. Have not reported to service center or manufacturer. Seems to be a system sensitivity issue that is a non serviceable issue. Problem occurred when vehicle under 1,000 miles and continues at 5,000 miles.
