2007 Mercedes Benz R320

PREFACE: I OWN AN AUTOMOTIVE REPAIR SHOP IN CARROLLTON TEXAS. I HAVE BEEN WORKING ON CARS SINCE 1968. I AM A THREE-TIME CERTIFIED MERCEDES-BENZ MASTER TECHNICIAN. IN DECEMBER, 2012 I REPLACED THE RIGHT FRONT AIR SPRING ON A 2007 MERCEDES R-320. THE MANUFACTURER IS AREN'T INDUSTRIES. THEIR PART NUMBER IS A-2587. LESS THAN TWO MONTHS LATER, THE AIR SPRING SUFFERED A CATASTROPHIC FAILURE. THE SPRING MATERIAL, WHICH IS SIMILAR IN CONSTRUCTION TO A TIRE, RUPTURED. THE VEHICLE WAS PARKED IN THE OWNER'S GARAGE WHEN THE "BLOW-OUT" OCCURRED. THE MILEAGE AT FAILURE WAS 49336. THE MILEAGE OF THE ORIGINAL REPLACEMENT WAS 49113. THE DISTRIBUTOR OF THE AIR SPRING OFFERED ME A WARRANTY REPLACEMENT. I REPLACED THE SPRING WITH, AT THIS POINT, NO FURTHER ISSUES. ON SEPTEMBER 10,2013 I REPLACED THE LEFT FRONT AIR SPRING. THAT SPRING FAILED TODAY, SIX DAYS SHY OF ONE YEAR AND AFTER ONLY 4200 MILES. BOTH OF THE REPLACEMENT AIR SPRINGS SUFFERED CATASTROPHIC "BLOW-OUT" FAILURES. WHEN THE LEFT SPRING FAILED TODAY, THE CAR WAS BEING DRIVEN. THE DRIVER MANAGED TO GET THE CAR OFF THE ROAD WITHOUT INCIDENT. HOWEVER, IT COULD HAVE RESULTED IN LOSS OF CONTROL OF THE CAR AND SERIOUS DAMAGE OR INJURY. I CONTACTED AREN'T ABOUT THEIR FAILURE RATES FOR THESE AIR SPRINGS. THEY STATED THEY HAVE ONLY AN 8% FAILURE RATE OF THIS PRODUCT. BECAUSE THE TWO FAILURES THAT I HAVE WITNESSED PRESENT A THREAT TO THE SAFETY OF THE VEHICLE AND OCCUPANTS, I WOULD LIKE SOMEONE TO SEE IF ADDITIONAL FAILURES OF THIS COMPANY'S PRODUCTS HAVE OCCURRED. *TR
