NHTSA ODI 11395838

FRONT RIGHT WHEEL WENT FLAT AND SUSPECTED TIRE HAD A SMALL LEAK. DEALER INSPECTED AND INDICATED THE WHEEL WAS CRACKED, CAUSING THE LEAK. WHILE WAITING FOR A REPLACEMENT, A VEHICLE INSPECTION INDICATED THE LEFT FRONT WHEEL WAS ALSO CRACKED, THOUGH NOT YET LEAKING AIR. THE VEHICLE HAD BEEN DEALER-SERVICED WITH OEM RUN-FLAT TIRES. DEALER INDICATED THAT THIS WAS NOT THE FIRST TIME THEY HAD SEEN IT. I OPTED TO PURCHASE AFTERMARKET WHEELS AS REPLACEMENTS AS ORIGINALS WERE OBVIOUSLY FRAGILE, AND EXPENSIVE. DATE IS ESTIMATED AS IT'S NOT CERTAIN WHEN THE WHEEL CRACK ACTUALLY OCCURRED. DEALER SERVICE COMPLETED ON THAT DATE.

MY CAR ONLY HAS 33000 MILES ON IT. THE WHEELS HAS PIRELLI RFT, THAT COMES WITH THE CAR. BOTH THE ORIGINAL MERCEDES FRONT RIMS OF MY CAR CRACKED WHILE DRIVING THE CAR WITH MY FAMILY. THIS IS HIGHLY CONCERNING AND LIFE THREATENING. THIS IS A KNOWN ISSUE WITH MERCEDES WHEELS AND 100S OF CUSTOMERS ARE IMPACTED BY THE SAME ISSUE. THE ISSUE WAS REPORTED TO MERCEDES AND MERCEDES DID NOT ACKNOWLEDGE. (HTTPS://MBWORLD.ORG/FORUMS/C450-C43-AMG/682223-CRACKED-WHEEL.HTML) (HTTPS://MERCEDESFORUM.COM/FORUM/GENERAL-TECH-5/MULTIPLE-FLAT-TIRES-CRACKED-RIMS-27633/). THESE WHEELS ARE ON HIGH PERFORMANCE CARS AND BECAUSE OF THIS DEFECT SOMEONE MIGHT GET INTO A SERIOUS ACCIDENT. THIS WAS BROUGHT TO NHTSA'S ATTENTION FEW TIMES. I WOULD REQUEST YOU TO KINDLY CONSIDER THIS MATTER SERIOUSLY AND INVESTIGATE IT. I WOULD ALSO REQUEST THAT MERCEDES WHEELS BE EXAMINED AGAINST THEIR QUALITY AND STRUCTURE SUPPORT . THIS IS REALLY SCARY AND PEOPLES LIFE DEPEND ON IT.

I TOOK IT BACK TO THE SERVICE DEPARTMENT AND THEY TOLD ME IT WAS A CRACKED RIM ,I RESPONDED BY LETTING THEM KNOW I NEVER RAN OVER ANY POTHOLES.THE RIM WAS REPAIRED, BUT A MONTH LATER AGAIN THE PROBLEM ACCURRED.MY CAR HAS BEEN IN THE SERVICE DEPARTMENT FOR THE SAME PROBLEM EVERY OTHER MONTH FOR THE SAME PROBLEM ON EACH OF MY TIRES ,ALL OF MY TIRES HAVE BEEN CRACKED WITHOUT ME RUNNING INTO POTHOLES.JUST YESTERDAY I RECEIVED MY CAR BACK FROM SERVICE AFTER A WEEK OF THEM HAVING IT FOR A CRACKED RIM AGAIN ON THE FRONT RIGHT SIDE.WHEN I LEFT THE SERVICE DEPARTMENT THE TIRE PRESSURE WAS AT 36 PERCENT THIS MORNING ALL THE TIRES ARE AT THEIR NORMAL PRESSURE EXCEPT THE RIGHT FRONT TIRE IT'S AT 30 PERCENT. IT IS LOSING AIR AGAIN. MY CAR HAS BEEN TO THE SERVICE DEPARTMENT OVER 15 TIME FOR PROBLEMS WITH CRACK RIMS WITHOUT ME RUNNING INTO POTHOLES. IS THERE A MANUFACTURING PROBLEM WITH THE RIMS?

I BOUGHT MY 2016 MERCEDES C63S AMG FROM A DEALER IN EDMOND, OKLAHOMA (JACKIE COOPER BMW) AND THEY SOLD ME THE CAR WITH LESS THAN 10% TREAD LEFT ON THE TIRES. SHORTLY AFTER THE PURCHASE I CALLED THE DEALER FOR ASSISTANCE AND THEY FLAT OUT DENIED ANY WRONG DOING. THEY CLAIMED THEY DID A "RIGOROUS INSPECTION" BUT SOMEHOW THE TIRES THAT WERE DOWN TO THEIR WEAR BARS PASSED IT. TO MAKE MATTERS WORSE, I PURCHASED A $4100 TIRE/WHEEL PACKAGE FROM THEM AND THEY ALSO HAVE NOT ACTIVATED THE SERVICE (AFTER 23 DAYS OF PURCHASE) SO I CANNOT GET NEW TIRES PUT ON WITHOUT PAYING AN EXTRA $1200 OUT OF POCKET FOR THE HIGH PERFORMANCE TIRES THAT THE CAR REQUIRES. MANAGEMENT HAS NOT RETURNED ANY OF THE CALLS & THE SALES AGENT (BRYAN LEONARD) ALSO HAVE NOT BEEN VERY HELPFUL. NEARLY A MONTH LATER AFTER THE PURCHASE THE CAR IS STILL SITTING IN THE GARAGE WITH TWO BUSTED TIRES & NO WAY TO REPLACE THEM UNDER WARRANTY BECAUSE THE DEALER IS REFUSING TO EXPEDITE THE WARRANTY ACTIVATION. I FINALLY GOT TIRED OF WAITING SO I TOOK THE HIT FOR THE FRONT TWO TIRES AND PAID A MOBILE SERVICE TO COME OUT AND REPLACE THEM. THE DEALER IS REFUSING TO REIMBURSING ME FOR THOSE 2 & ALSO REFUSING TO ACTIVATE THE WARRANTY SERVICE IN A TIMELY MANNER. I'VE ATTACHED THE PICTURES OF THE DRIVER SIDE FRONT TIRE THAT IS ON IT'S LAST THREAD & ALSO THE RECEIPT FOR THE FRONT TWO THAT I REPLACED OUT OF POCKET. IT'S DECEMBER 21ST NOW AND STILL NO ACTIVATION ON THE WARRANTY. I'VE NEVER FELT A BIGGER BAIT & SWITCH FROM A DEALER BEFORE.

SINCE THE PURCHASE OF OUR 2016 MERCEDES IN DECEMBER OF 2015, WE HAVE BEEN EXPERIENCING THE WARNING DISPLAY OF THE TIRE PRESSURE ON NUMEROUS OCCASIONS. THE FIRST OCCURRENCE PRIOR TO TAKING IT TO A DEALERSHIP MY WIFE TOOK IT A LOCAL TIRE SHOP WHERE THE OWNER PUT AIR IN THE TIRES AND THE LIGHT WENT OFF. IT OCCURRED SEVERAL MORE TIMES AND I ALWAYS WENT TO LOCAL GAS STATIONS AND PUT AIR IN. AFTER GETTING FRUSTRATED WE DROVE TO THE DEALERSHIP IN VALENCIA CALIFORNIA SHOWED THE SERVICE ATTENDANT THE ALERT ON THE DASH. HE RETRIEVED AN AIR PUMP AND PUT AIR IN ALL THE TIRES ACCORDING TO THE SPECS AND SENT US ON OUR WAY WITHOUT DISCUSSING THE WARNING ALERT WHICH WENT OFF. AFTER APPX A WEEK AND A HALF OF DRIVING WE RETURNED WITH THE SAME PROBLEM.. MY WIFE SPENT 4 HOURS WAITING AND ACCORDING TO THE SERVICE RECEIPT THEY SAID THE TIRES WERE ROTATED AT THE CLIENT'S REQUEST AND NEVER MENTIONED THE ALERT ON THE DASH BEING REPORTED BY THE OWNER. WE HAVE TAKEN IT A COUPLE OF MORE TIMES ONE OF WHICH THE CHECKED AND SUBMERGED ALL THE TIRES TO CHECK FOR LEAKS AND RIM DAMAGE WHICH THEY ALL CHECK OUT PROBLEM FREE. AND AS USUAL THE ALERT CAME BACK ON AFTER APPX. A WEEK AND A HALF OF DRIVING. TODAY THE ALERT IS BACK ON WITH ANOTHER RED WARNING SIGN AND WE ARE GOING TO DRIVE IT BACK TO THE DEALERSHIP IN VALENCIA TOMORROW SINCE THEY WILL NOT SEND A TOW SERVICE OUT WHEN THE OWNER'S MANUAL CLEARLY STATES "IN DANGER OF AN ACCIDENT PULL OVER AND DO NOT DRIVE". THIS IS THE SECOND RED LIGHT WARNING ON THE VEHICLE AND IT APPEARS THEY HAVE NO IDEA WHAT THE PROBLEM IS. ON THE FIRST OCCASION WHEN THE RED LIGHT CAME ON WE WERE INSTRUCTED TO DRIVE THE VEHICLE IN REGARDLESS OF THE RED LIGHT WARNING. I CONTACTED THE MERCEDES BENZ USA COMPLAINT DEPARTMENT THIS MORNING AND FILED A COMPLAINT. THE DEPT OF CONSUMER AFFAIRS INSTRUCTED ME TO FOLLOW THE ARBITRATION GUIDELINES IN THE BACK OF THE MANUAL.
