NHTSA Complaint #11128778 — 2011 INFINITI M56

WHEN YOU GO TO APPLY THE BRAKE IT OFTEN LOCKS UP AND STOPS IMMEDIATELY. THIS IS AN ISSUE THAT COMES AND GOES. IT ALSO AT THE SAME TIME IT IS STOPPING ABRUPTLY WITHOUT APPLYING THE BRAKE COMPLETELY IT WILL DO THE OPPOSITE AND THE BRAKE WILL DEFLATE ALL THE WAY TO THE FLOOR BEFORE STOPPING. WHILE STOP IT WILL LOSE PRESSURE AND THE BRAKE WILL SLOWLY GO TO THE FLOOR. HAVE TAKEN IT SEVERAL PLACES AND THEY CAN NOT FIX. HAVE HAD ALMOST ALL BRAKE PARTS REPLACED AND OR CHECKED. THIS HAPPENS EVER TIME BRAKES ARE APPLIED FOR A WEEK OR SO THEN GOES AWAY THEN COMES BACK PERIODICALLY. HAS BEEN HAPPENING FOR OVER A YEAR. MECHANICS HAVE ENCOIUNTERED THE ISSUE AND CAN NOT FIGURE OUT WHAT IS CAUSING IT, INCLUDING INFINITI.
