NHTSA Complaint #11417878 — 2010 RAM 1500

vehicle has 113,000 miles on it now, the engine is knocking so I brought it in to Weber in Detroit Lakes Minnesota they say it needs cams and lifters e c t. Estimate is $5,000 or new engine $9,000 so now I can't get to work! I commute back and forth every day 70 miles each way, this vehicle should not have this problem as of yet in my eyes! Will the factory / dealership warranty this fix for me? I purchased vehicle from Weber in Detroit Lakes almost four years ago with 80,000 miles on it I have only driven at 33,000 miles since then!! I don't have that kind of money for this fix nor can I afford to buy a replacement vehicle but now the knocking you can hear it outside the vehicle but you cannot hear it in the cab of the vehicle so how long has this problem actually been going on before the fact of me noticing it just very recently so then I quit driving it immediately and brought it directly to Weber as per appointment
