Just after the factory warranty expired, the engine was running rough and hot, and \"check engine\" light illuminated. My local garage quickly diagnosed the problem as a failed cylinder head, stated that it is common with Mercedes 4-cylinder engines from about 2017, and said Mercedes may cover it since it is a \"known problem\" and shouldn't happen with that mileage.  I was charged $7,860 by my local Mercedes dealer, and despite multiple contacts with MercedezUSA, they refuse to acknowledge this is a problem or cover the cost, although in on-line the forums some people were arbitrarily reimbursed.  There should be a recall to check for this obvious defect and should be covered.  This defect can cause sudden engine failure and is a significant hazard to the driving public.","products":[{"type":"Vehicle","productYear":"2021","productMake":"MERCEDES-BENZ","productModel":"C 300","manufacturer":"Mercedes-Benz USA, LLC"}]}]}
