NHTSA Complaint #11132327 — 2011 DODGE RAM 1500

MY TRUCK IS IN EXCELLENT CONDITION AND HAS BEEN FAITHFULLY SERVICED AT THE DEALERSHIP WHERE PURCHASED. IT HAS 130K HIGHWAY MILES. DRIVING AWAY FROM DEALERSHIP AFTER ROUTINE OIL & LUBE, I NOTICED THE ENGINE WAS IDLING ROUGHLY AT A NEARBY STOP LIGHT. A FEW DAYS LATER THE CEL ILLUMINATED. ON 19 JUL 2018 I RETURNED TO THE DEALERSHIP TO HAVE IT CHECKED. THE INVOICE/ SERVICE SUMMARY STATES:"CHECK ENGINE LIGHT IS ON. TEST AND FOUND CYLINDER #3 MISFIRE. SWAP SPARK PLUG, AND COIL. STILL HAS #3 MISFIRE. CAN HEAR POSSABLE LIFTER NOISE. WILL NEED TO TAKE APART ENGINE TO TEST." THE SERVICE ADVISER TOLD ME CAM SHAFT LIFTER WEAR IS A KNOWN PROBLEM WITH THE 5.7 LITER HEMIS. HE SAID THEY'VE HAD SEVERAL CASES AT THAT DEALERSHIP, AND THERE WERE 70,000 PARTS ON BACK ORDER NATION WIDE RELATED TO THE PROBLEM. HE ALSO TOLD ME THE ESTIMATED COST TO REPAIR WOULD BE $3,500 - $4,000. THE INVOICE TO CHECK THE CEL WAS $122.91. I WAS TOLD IT SHOULD BE SAFE TO DRIVE. INTERNET SEARCH OF THIS PROBLEM CONFIRMS IT IS WIDESPREAD. MY ENGINE NOW SPUTTERS AND SHUDDERS WHEN UNDER PRESSURE/ ACCELERATION. CEL HAS REMAINED ILLUMINATED. I'M STUCK: CAN'T GET PARTS TO REPAIR, CAN'T SELL/ TRADE IT WITH THIS ISSUE, GROWING MORE CONCERNED ABOUT DRIVING IT. HELP PLEASE.
