NHTSA Complaint #11217797 — 2012 MERCEDES-BENZ C250

MY C250 STARTED MAKING A NOISE WHEN YOU FIRST START THE CAR. CHOKING AND HESITATIONS TO START, BUT YET WOULD START AFTER A MOMENT OR 2. THE NOISE WAS UNFAMILIAR. THIS NOISE WOULD CONTINUE THROUGH OUT THE DAY, AS LONG AS THE CAR SET FOR MORE THAN 15-20 MINUTES. I WOULD GO INTO THE STORE, TO SHOP COME BACK OUT TO THE CAR AN THE NOISE WOULD STILL BE THERE AFTER 15-20 MINUTES. I TOOK MY CAR TO THE MERCEDES BENZ DEALER IN HOUSTON, TEXAS NORTH. AFTER A $200 DIAGNOSE COST. THE CAM SHAFT ADJUSTER IS OUT. COSTING ANOTHER $4,575.68. MY CAR IS A 2012, WHICH I BROUGHT IN 2014 WITH LESS THAN 7,000 MILES. NOW IT IS 2019 WITH ONLY 87,885 MILES ON MY CAR, I DON'T KNOW WHAT THIS PART IS FOR OR WHY MY CAR NEEDS THIS. ALL I KNOW IT COST $4,575.68. WAY TO MUCH FOR SOMETHING I KNOW NOTHING ABOUT. CAN'T GET IN TOUCH WITH MANUFACTORY TO COMPLAIN AND MERCEDES HEADQUARTER HASN'T RETURN MY CALL. PLEASE GIVE ME ADVISE, AS TO WHAT TO DO WITH MY COMPLAINT.
