“low braking power” message
WE TOOK A CAR FOR LEASE FROM LEXUS. THE FIRST WEEK, WE REALIZED THE BRAKES WEREN'T WORKING WELL. WE TOOK THE CAR TO THE SHOP AND THEY SAID NOTHING WAS WRONG. THEN, A COUPLE OF MONTHS LATER IT HAPPENED AGAIN AND THEY SAID THE SAME THING. LAST WEEK, AFTER 2 YEARS, I WAS DRIVING AND SO WAS MY DAUGHTER ( TWO DIFFERENT TIMES ) AND WE COULDN'T BREAK THE CAR. THE CAR DROVE RIGHT PAST THE INTERSECTION ON A RED LIGHT. THANK GOD THERE WAS NO PEDESTRIANS OR VEHICLES AT THAT SECOND. WE BROUGHT IT TO ALEXUS AND THEY TESTED THE BRAKES AND SAW A PROBLEM WITH THE BRAKES. THE PRESSURE WAS LOW AND THE METAL WAS SCRAPING. THEY ASKED FOR A LARGE SUM AND SAID WE NEVER COMPLAINED BEFORE.
