2005 SUZUKI RENO Tires Problems

I WOKE UP TO FIND MY TIRE WAS COMPLETELY FLAT ABOUT A MONTH AND A HALF AGO. THE PROBLEM ACCORDING TO THE AUTO SHOP WAS A BAD VALVE STEM, WHICH I HAD TO GET REPLACED. SINCE THEN I HAVE HAD ALL OF THE OTHER TIRES ON MY CAR LEAK AIR TO THE POINT WHERE THEY HAD LESS THAN 5 POUNDS OF AIR LEFT IN THEM. I WENT BACK TO THE SAME AUTO SHOP AND HAD TO REPLACE THE LAST 3 VALVE STEMS ON MY REMAINING THREE TIRES. THE TIME FRAME INVOLVED HERE WAS 4 VALVE STEMS REPLACED, ONE FOR EACH OF MY TIRES IN A TOTAL OF A 2 MONTH PERIOD. *TR

DT: 2005 SUZUKI RENO. THE CONSUMER BOUGHT THE CAR IN DECEMBER 2004 AS NEW VEHICLE. THE GAS MILEAGE WAS GETTING LOWER AND LOWER. TOOK THE CAR TO THE DEALERSHIP, AND THEY TOLD HER THAT THEY DID NOT HAVE THE TECHNOLOGY TO FIX THE CAR. THE DEALERSHIP HAD NO IDEA WHAT WAS WRONG WITH VEHICLE. UPON FIRST PURCHASING THE CAR CONSUMER WAS GETTING 230 MILES TO THE TANK. CURRENTLY , WAS ONLY GETTING AROUND 10 MILES TO A TANK. HAD NOT TAKEN VEHICLE TO ANY OTHER DEALERSHIP FOR REPAIRS. .*AK THE VEHICLE TIRE HAD TO BE CHANGED AT 18000 MILE BECAUSE THE METAL STARTED SHOWING. *NM
