I HAD PURCHASED A 2015 BUICK ENCORE VEHICLE ON MARCH 03, 2020, THAT HAD A "NOT FOR SALE" YELLOW STICKER ON THE WINDSHIELD. I HAD NOTICE THAT THE VEHICLE MADE A THUMPING SOUND UNDER THE HOOD ON THE DRIVER SIDE WHEN RIDING ON THE HIGHWAY. I TOOK IT TO JOHNNY LONDOFF SERVICE DEPT., BUT WAS TOLD THAT NOTHING WAS WRONG WITH IT. IN ADDITION, TO NOTICING THAT THE VEHICLE WOULD ROLL BACKWARDS ON THE SMALLEST OF INCLINE. AS TIME WENT ON THE VEHICLE WOULD ROLL BACK, THEN ROLL FORWARD ON LEVELED GROUNDS WHEN I WOULD TAKE MY FOOT OFF OF THE BRAKE PEDAL. I TOOK THE VEHICLE BACK TO JOHNNY LONDOFF SERVICE DEPT., AND AGAIN WAS TOLD THAT NOTHING WAS WRONG WITH THE VEHICLE. I TOOK IT TO TELLE TIRES AND AUTO CENTER AND FOUND THAT THE SUSPENSION WAS WORN OUT ON THE FRONT AND BACK OF THE VEHICLE, WITH STRUTS AND SPARK PLUGS NEEDED. THIS VEHICLE ROLLS BACK WHEN SITTING AT A TRAFFIC LIGHT, AT, IN LINE AT A FAST FOOD DRIVE THROUGH, AND JUST EVERYDAY DRIVING. JOHNNY LONDOFF SHOULD HAVE FIXED THE DAMAGES AND/OR REPAIRS NEEDED BEFORE SELLING ME THE VEHICLE. I WOULD NOT RECOMMEND BUYING A VEHICLE OR DOING BUSINESS WITH THEM. *JS

THERE WAS A PIPE OR LINE THAT PART OF THE AIR CONDITIONING. THE MANIFOLD HAS BURNED THAT PIPE AND NOW AC ISN'T WORKING. THE FIX WILL BE $900. THE SYSTEM THAT IS IN CONTROL OF THE SEAT THAT IS SUPPOSED TO ADJUST THE SEAT WHEN YOU GET INTO CAR DOES NOT WORK. WIRELESS DOESN'T REMEMBER THE PHONE CONNECTIONS FROM ONE DRIVE TO THE NEXT. *TR

TRIED TO STOP BEFORE A RED SIGN ON A CITY STREET, THE CAR ACCELERATED ON ITS OWN, PASSED THE RED LIGHT AND RUN AT ABOUT 60 MPH ON A 35 MPH STREET FOR ABOUT HALF A MILE AND THEN STOPPED BY ITSELF. PRESSING THE BRAKES AND EVEN PUTTING IT ON PARK DID NOT HELP. I AM LUCKY TO BE ALIVE WITH MY TWO PASSENGERS, AND LUCKY NOT TO KILL ANYBODY OR CAUSE PROPERTY DAMAGE.

THE CAR HAD BEEN PARKED IN AN UNHEATED GARAGE FOR MORE THAN 24 HOURS. I STARTED IT, PUT MY FOOT ON THE BRAKE PEDAL, AND PUT IT IN GEAR (R). THE CAR LUNGED BACK AT A HIGH RATE OF SPEED. MY FOOT WAS STILL ON THE BRAKE. TO AVOID HITTING A VEHICLE BEHIND IT IN THE DRIVEWAY, I SHIFTED TO DRIVE (D) AND THE CAR IMMEDIATELY STARTED FORWARD STILL AT A HIGH RATE OF SPEED. THE BRAKES DID NOT SLOW THE CAR DOWN. I BUMPED THE FRONT WALL OF THE GARAGE AND AGAIN SHIFTED INTO R. THE CAR STARTED MOVING BACK AGAIN AND THE BRAKES DID NOT WORK. I TURNED THE ENGINE OFF AND THE CAR BEGAN SLOWING AND CAME TO A STOP AFTER BUMPING THE VEHICLE ABOUT 20 FEET BEHIND IT. MY FOOT WAS ON THE BRAKE PEDAL THE WHOLE TIME. I CHECKED FOR OBSTRUCTIONS AROUND THE BRAKE PEDAL AND FOUND NONE. AFTERWARD, WHEN I STARTED THE CAR AGAIN, IT DROVE NORMALLY WITHOUT TROUBLE. THERE WAS NO APPARENT DAMAGE TO THE CAR AS A RESULT OF EITHER COLLISION BUT THE GARAGE WALL SUFFERED SOME MINOR DAMAGE.
