SUBJECT:

Intermittent Engine Shudder While Driving

 

OVERVIEW:

This bulletin involves replacing the engine cylinder heads.

 

MODELS:

2014(WK)JeepeBay logo Grand Cherokee
2014(DS)RAMeBay logo 1500 Pickup

 

NOTE: This bulletin applies to vehicles equipped with the 3.0L V6 Turbo Diesel (Sales Code EXF).

 

SYMPTOM/CONDITION:

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:

Valve stem seals on replacement head are designed to prevent excessive carbon build up from light load drive cycles.

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 1,600 – 2,000 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.

 

DIAGNOSIS:

Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTCs or symptom conditions, other than the ones listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.

If the customer describes the symptom/condition listed above, perform the Repair Procedure.
