I own a 2000 Dodge Durango and have consistently maintained it for years with few problems. Last week while driving it a "check gauge" light came on. I took it to be serviced and was told that the engine needs to be replaced. Apparently Dodge has a defect with its Durango and Dakota engines that leads to sludge. The driving shaft has begun to break apart as a result. I am upset because Dodge has issued no recalls nor have they ever suggested that synthetic oil be used, which would have prevented this problem. I am now faced with replacing this truck or paying $6000 to replace the engine. Has anyone else had a similar situation?
