NHTSA Complaint #11100103 — 2008 LEXUS IS 250

I PURCHASED 4 BRAND NEW TIRES FROM FIRESTONE COMPLETE AUTO CARE ON 12/27/2015. I HAVE HAD SEVERAL INCIDENTS WITH THE TIRES INCLUDING FREQUENT BUBBLE FORMATION AND A TIRE BLOW OUT ON THE HIGHWAY. I BELIEVE THE FREQUENCY OF THESE INCIDENTS WARRANT INVESTIGATION AS TO POSSIBLE DEFECTS IN THIS BRAND AND LINE OF TIRE THAT COULD BE LIFE THREATENING. I HAD A TIRE BLOWOUT OF THE LEFT DRIVERS SIDE TIRE WHILE ON THE HIGHWAY ON MY WAY TO WORK IN RUSH HOUR TRAFFIC ON 3/30/17. FORTUNATELY, I WAS ABLE TO GET THE CAR IN CONTROL AND GET OFF OF THE NEXT EXIT. I HAD THE TIRE REPLACED LATER THAT MORNING. NEXT, I WAS AT THE LEXUS DEALERSHIP IN NOVEMBER OF 11/2017 FOR AN ALIGNMENT AND A BUBBLE WAS FOUND IN THE SIDEWALL TIRE. THIS TIRE WAS REPLACED AT THE LEXUS DEALERSHIP. ON 4/15/18, I WAS DRIVING ON THE HIGHWAY AND MY CAR FELT UNBALANCED AND THE CHECK TIRE LIGHT CAME ON. I ATTEMPTED TO PUT AIR IN THE RIGHT FRONT PASSENGER TIRE BUT WAS UNABLE TO GET AIR IN. I BROUGHT THE CAR TO FIRESTONE AND WAS TOLD I NEEDED A NEW TIRE. ON 6/2/18, I BROUGHT THE CAR TO MIDAS FOR AN EMISSIONS SYSTEM CHECK AND THE TECHNICIAN SHOWED ME A BUBBLE ON THE SIDEWALL OF THE LEFT DRIVERS SIDE TIRE. I BROUGHT THE CAR TO FIRESTONE AND THIS WAS VERIFIED. I WAS CHARGED AND THE TIRE REPLACED. HAVING PURCHASED THESE 50,000 MILE TIRES IN DECEMBER OF 2015 WITH 93,000 MILES ON MY VEHICLE THIS IS AN EXCESSIVE AMOUNT OF ISSUES AT 126,000 MILES. I HAVE BOTH SAFETY AND FINANCIAL CONCERNS ABOUT THIS PRODUCT. I HAVE ATTEMPTED TO SPEAK WITH FIRESTONE DIRECTLY AT THE STORE, THEY DENY ANY ISSUE WITH THE TIRES. I RECEIVED DISCOUNT PRICING FOR REPLACING 2 TIRES BUT NO OTHER ACCOUNTABILITY BY FIRESTONE. I BELIEVE THIS WOULD HAVE TO OCCUR AT A HIGHER LEVEL. THE TIRES ARE BRIDGESTONE DRIVEGUARD BL WITH RUN FLAT 225/45R17 91W 50,000 MILE.
