My BMW 330XI 2018 wagon recently passed 40000 miles. My wife heard a rubbing noise when braking a few days ago. We took car into a repair shop and they found the rear brake pads were worn down to the metal. At no time did a brake wear warning light ever alert us to this!
I WAS STOPPED AT A STOP LIGHT WITH MY FOOT ON THE BRAKE FOR ABOUT A MINUTE WHEN THE CAR SUDDENLY ACCELERATED AND LUNGED FORWARD.I APPLIED MORE PRESSURE TO THE BRAKE,ALL THE WAY TO THE FLOOR , BUT THE CAR WOULD NOT STOP. THE CAR IN FRONT OF ME IS THE ONLY THING THAT STOPPED THE CAR ,AS HE WAS STOPPED TOO. THE CAR THEN BOUNCED BACKWARD AND TURNED OFF BY ITSELF. I WAS ON A MAIN STREET AT A LIGHT. IT WAS FORTUNATE THAT ANOTHER CAR WAS STOPPED IN FRONT OF ME BECAUSE IT STOPPED THE CAR AND PREVENTED MY CAR FROM HITTING PEDESTRIANS.
