Service bulletins for the 2014 Ram 1500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

90033572019-07-15. Service bulletin. ENGINE; EQUIPMENT. ADAPTER, Engine Oil Filter (Pentastar V6) Engineering is seeking information regarding OFA leaks. Questions/info can be directed to: Bob Jackson (248) 944-0466 - bob.jackson@fcagroup.com Ron Dallison (248-292-9510) ron.dallison@fcagroup.com Joe Lovell (734) 309-6467 - joe.lovell@fcagroup.com If no response in 15 minutes, proceed with repair. All vehicles equipped with a 3.2L or 3.6L except for model year 2014 vehicles with leak concern: 1) Ensure the Oil Filter Adapter (OFA) Cap O-ring is seated in the proper groove in the cap and not damaged or cut. 2) If replacing the (OFA) due to a leak detected between (OFA) and block. Ensure the torque on the 5 bolts are torqued to 12nm. If not record the actual values, torque to 12nm and contact the FCA employees listed below. 3) Remove the (OFA) and replace the O-ring and gaskets only (Kit #68191356A$), NOT THE OFA. 4) If oil was drained, add oil dye to ensure the leak is repaired. For model year 2014 vehicles replace the Oil Filter Adaptor.

09-006-15 REV A2019-05-20. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ENGINE AND ENGINE COOLING. Intermittent Engine Shudder While Driving This bulletin involves replacing the engine cylinder heads. A small number of customers may experience a slight engine shudder while driving. They may state that the condition feels and sounds like driving over rumble strips. It may also be perceived as an internal transmission issue or engine misfire. No Diagnostic Trouble Codes (DTCs) will set as a result of this condition. DISCUSSION: The root cause of the engine shudder has been found to be due to excess carbon build-up on the exhaust valve stems and will typically happen on vehicles driven mostly in light load conditions. As a result, new cylinder heads have been released that are equipped with newly designed valve stem seals. These newly designed seals are designed to help prevent excessive carbon from building up on the valve stems. Although it may be hard to reproduce, engine shudder resulting from these excess carbon deposits, will typically only happen under the following driving conditions: ? Steady speeds between 50 and 70 mph (80 and 113 kph). ? Engine speed between 1600 - 2000 RPM. ? Present during engine warm up to operating temperature after a cold soak. ? Only present for a few seconds at a time and often during a 6-7 upshift. ? Light load acceleration or while driving up a slight grade. ? Symptom will go away either by aggressively applying the accelerator pedal or going into a zero throttle deceleration.
