2015 BUICK ENCORE Complaints

NEW BUICK 2015 ENCORE 1. APPYING BRAKES WHEN BACKING OUT OF GARAGE CREATES A SHRILL SQUEAL. 2. WHEN SLOWING FOR THE STOP SIGN AT THE END OF THE STREET, APPLYING BRAKES MAKES A MOANING SOUND AND SLIGHT VIBRATION. 3. WHEN I APPLY BRAKES TO SLOW DOWN AT ABOUT 5 MPH SUCH AS STOPPING AT AN INTERSECTION, THE BRAKES 'GRAB' RATHER THAN SLOWING SMOOTHLY. ALL PROBLEMS HAPPEN IN THE MORNING AFTER THE CAR HAS SET OVERNIGHT, AND THEY USUALLY GO AWAY AFTER DRIVING ENOUGH TO USE THE BRAKES A NUMBER OF TIMES. LAST WEEK I DROVE IN A HARD RAIN FOR 20-30 MINUTES GETTING HOME. PARKED CAR OVERNIGHT. BRAKE WORKED WITHOUT THE ABOVE PROBLEMS FOR THE NEXT TWO DAYS, THEN STARTED AGAIN. DEALER SAYS THEY (GM) ARE AWARE OF THE PROBLEM ON SOME 2015 ENCORES AND ARE "WORKING ON IT" BUT IT IS SAFE, AND MIGHT BE A FEW MONTHS BEFORE A FIX.
