20191202SERVICE BRAKES
A FEW WEEKS AFTER I BOUGHT MY VEHICLE THE BRAKES STARTED SQUEAKING. I MENTIONED THIS TO ONE OF THE SERVICE PEOPLE AND SHE SUGGESTED IT MIGHT BE A SMALL STONE. IT CONTINUED TO SQUEAK AND THEN IT STARTED SCREECHING. PEOPLE IN THE PARKING LOT AND AT HOME ASKED ME IF I WAS REALLY DRIVING A MERCEDES-BENZ. THE BRAKES WERE CHANGED EVENTUALLY AND THE SERVICE GENTLEMAN SAID IT WOULDN'T HELP AS IT WOULD START AGAIN. TRUE TO HIS WORD. THEY ARE SCREECHING AGAIN. IT'S EMBARRASSING TO SAY THE LEAST AND IT DEFINITIVELY HURTS OUR EARS. I HAVE HAD 4 MB'S AND I HAVE TO SAY I HAVE NEVER HAD THIS PROBLEM. SHAME ON YOU!
