NHTSA Complaint #10917235 — 2007 SATURN SKY

I PURCHASED A USED SATURN SKY 2007 VEHICLE. JULY 26TH 2016. I NOTICED IMMEDIATELY THE SAME DAY AS A MATTER OF FACT A NOISE FROM THE BACK END. I TOOK CARE BACK A AND THEY PUT GREASE IN DIFERENTIAL.. BUT AFTER A FEW DAYS IT WAS WORSE THAN EVER. I PURCHASED THE EXTENDED WARRANTY PLAN. AFTER THEY TRIED LOOKING AT MY CAR. I CALLED MY WARRANTY COMPANY AND ASK IF THEY COULD RECOMMEND A SERVICE CENTER TO TAKE MY CAR TO HAVE IT SERVICED. WHICH I THEN PROCEEDED TO DO. AND MY VEHICLE IS STILL THERE. THEY SENT A USED DIFERENTIAL THAT WAS BAD. I ASKED THE WARRANTY REPRESENTATIVE AT THAT TIME TO SEND ME A NEW ONE WHICH MY CONTRACT STATES CLEARLY I CAN HAVE. BUT ONCE AGAIN THEY SENT ANOTHER BAD USED ONE. AND THEN ANOTHER. ALONG WITH TWO OTHERS THAT WERE NEVER DELIVERED. AND I'VE BEEN OFFERED A RENTAL FOR 8 DAYS TOTAL. AND IT IS NOW OCT 18TH.2016. I HAVE NO CAR. GM HAS THIS PART NOW ON NATIONAL BACK ORDER. AND DOES NOT KNOW WHEN A PART WILL BE AVAILABLE. I ATTEMPTED TO CONTACT DIFFERENT MACHINE SHOPS TO SEE IF IT CAN BE REBUILT THEY HAVE TRIED TO FIND PARTS TO REBUILD IT THERE ARE NONE. I FEEL I HAVE DONE EVERYTHING POSSIBLE TO FIX THIS VEHICLE. AND IT'S A LEMON.
