MY HUSBAND'S CAR (2010 JEEP COMPASS) STOPPED SUDDENLY FOR NO REASON WHILE I WAS GOING ABOUT 40-45MPH SUNDAY 8/23. EVEN THOUGH I WAS WEARING A SEAT BELT, I WAS THROWN FORWARD OUT OF MY SEAT VERY HARD. BY THE END OF THE DAY I WAS IN SO MUCH PAIN I ENDED UP SEEKING URGENT CARE, WHERE I FOUND I HAVE WHIPLASH AND SPRAINED BACK AND HAND/THUMB (WHICH WAS FORCED BACKWARDS) AND AM NOW GETTING PHYSICAL THERAPY FOR IT. A FEW WEEKS AGO, THE WARNING LIGHTS FOR THE ANTILOCK BRAKES, 4 WHEEL DRIVE AND TRACTION CONTROL STARTED FLASHING. WE TOOK IT TO THE WALDORF MD JEEP DEALER. THEY WERE TOO BUSY TO WORK ON IT RIGHT AWAY BUT SAID "IT'S NOT A SAFETY PROBLEM. IT'S SAFE TO DRIVE". LAST WEEK, IT BEGAN DECELERATING UNEXPECTEDLY AT ABOUT 25MPH, SO ON THURSDAY NIGHT, 8/19, WE TOOK IT AND DROPPED IT OFF OVERNIGHT AT A LARGER DEALER- OURISMAN JEEP IN BOWIE, MD. ON FRIDAY 8/20 OURISMAN SAID THAT THE BACK TIRES DIDN'T MATCH THE FRONT TIRES (THE BACK TIRES WERE NEW AND FRONT TIRES HAD A LITTLE WEAR, BUT WERE SAME BRAND AND SIZE, ALTHOUGH DIFFERENT MODEL), AND ALL WE NEEDED TO DO WAS GET NEW MATCHING TIRES FOR THE FRONT TO MATCH THE BACK. WE DID THAT THE VERY NEXT MORNING (SATURDAY, 8/22) . ON SUNDAY MORNING, 8/23, IN SPITE OF THE BRAND NEW TIRES THAT WERE SUPPOSED TO FIX THE PROBLEM, I WAS NEARLY THROWN THROUGH THE WINDSHIELD WHEN THE CAR SUDDENLY STOPPED. WE COMPLAINED TO OURISMAN'S, SERVICE MANAGER (THE DEALER WHO HAD TOLD US THAT ALL WE NEEDED WAS NEW TIRES) ABOUT IT, AND THE SERVICE MANAGER STIL
