NHTSA Complaint #11084723 — 2012 DODGE RAM 1500

2012 RAM1500 - 74,250 MILES. STARTED ON 3/5 - GOT OFF THE HIGHWAY TO GAS UP. FILLED IT AND THEN CHECK ENGINE LIGHT CAME ON. BELIEVED IT TO BE "GAS CAP" ISSUE, SINCE I JUST GASSED UP. BROUGHT IT TO A AUTO PARTS STORE FOR A QUICK CHECK. P303. ENGINE MISFIRE CYLINDER 3. INITIALLY REPLACED IGNITION COIL, THEN SPARK PLUGS, NO CHANGE IN ISSUE. EACH TIME THE LIGHT CAME ON, I WAS DRIVING ABOVE 50 MPH. TAKEN IT AGAIN TO TWO AUTO PARTS STORES, AND EACH GAVE THE SAME ERROR CODE OF P303. TAKEN IT CAR REPAIR CENTER, THEY DIAGNOSED, ENGINE MISFIRE TOO, BUT ALSO SEEN IN OTHER CYLINDERS. REPLACED ALL IGNITION COILS AND ALL SPARK PLUGS, SAME ISSUE. CLEANED FUEL SYSTEM 2X BELIEVING IT WAS CARBON BUILD UP, STILL CHECK ENGINE LIGHT, SAME ERROR CODE. ADVISED BY SHOP TO CONTACT RAM TRUCKS, NOT THE DEALER TO ASK FOR ASSISTANCE, THEY, THE SHOP, INDICATED THAT THE ISSUE THEY SEE, IS THE CAMS AND LIFTER NOT WORKING, AND IT IS A "KNOWN" ISSUE. CONTACTED RAM TRUCKS, THEY OPENED A CASE AND DIRECTED ME TO TAKE TO A DEALERSHIP TO GET IT DIAGNOSED AS THE FIRST STEP. IN TALKING WITH THE SERVICE MANAGER, HE SAID, THE ENGINE IS MISFIRING AT "IDLE" NOT AT HIGHER SPEEDS. THEY ARE GOING TO WORK ON AN ESTIMATE FOR TWO POSSIBLE SOLUTIONS, ONE BEING THE CAMS/LIFTERS AND THE OTHER WAS SOMETHING ELSE, MY FAULT FOR NOT GETTING THAT OTHER, BUT BELIEVING IT IS THE CAM/LIFTER ISSUE. AT THIS TIME WAITING ON DETERMINATION. BUT UNSURE WHAT HELP, IF ANY, WILL BE OFFERED FOR THIS ISSUE. RESEARCH ON THIS SITE AND OTHERS INDICATE QUITE A LOT OF PROBLEM WITH "TICKING" OR CAMS/LIFTERS.
