NHTSA Complaint #10238322 — 2008 PONTIAC GRAND PRIX

I RECENTLY PURCHASED A 2008 PONTIAC GRAND PRIX FROM ENTERPRISE USED CAR. THEY LET ME DRIVE IT AROUND THE BLOCK, IT WAS COMFORTABLE. WHILE I WAS DRIVING IT HOME ON THE FREEWAY, IT STARTED TO SHAKE REALLY BAD. WHEN I GOT OFF OF THE FREEWAY I COULD HEAR THIS THUNK IN THE BACK TIRE. SO THE NEXT DAY I TOOK IT BACK AND TOLD THEM I DON'T WANT THIS CAR SOMETHING IS WRONG WITH IT. SO THEY PUT IT IN THE SHOP, AND I TEST DROVE OTHER VEHICLES. THIS TOOK A COUPLE OF DAYS. AT THE END OF THE WEEK, I DIDN'T FIND ANYTHING I LIKED. THEY TOLD ME MY CAR WAS DONE, I TOLD THEM I DIDN'T WANT THAT CAR. THEY ENDED UP PUSHING IT ON ME. THEY SAID THEY PUT NEW TIRES ON IT. WHILE I WAS DRIVING HOME ON THE FRWY, IT STARTED SHAKING AT 65MPH. I DON'T WANT THIS CAR. AND THEY TELL ME THEY CANT TAKE IT BACK. I FEEL THEY SOLD ME AN UNSAFE CAR. WHAT CAN I DO FOR THEM TO TAKE BACK THEIR 15,000.00 UNSAFE LEMON? *TR
