Four Common Problems With the 3.6L Pentastar V6 Engines that We Can Repair

The 3.6 L FCA Pentastar V6 Engine is an overwhelmingly durable and reliable engine. That’s why it’s been used in in more than ten million Chrysler, Dodge, and Jeep vehicles since 2010. With proper maintenance the 3.6L Pentastar engine can provide years of reliable service. However, no product is perfect, and the 3.6-liter Fiat Chrysler Automobile’s (FCA) Pentastar V6 engine is no exception. Unfortunately, problems with this type of engine can be challenging to diagnose, unless you take it to a shop that is highly experienced with these types of engines. At Nerger’s Auto Express, we’ve repaired countless 3.6L FCA engines in vehicles ranging from Jeep Wranglers to Dodge Chargers, and our experience means that we can diagnose and repair common and complicated engine problems quickly.


Here’s a look at four common problems that we frequently repair with the 3.6L Pentastar V6 engine.



  1. Pentastar V6 Engine Problem:  Misfire/Check Engine Light

If your car misfires, the check engine light will also come on, and the most common cause of a misfire or check engine light is a cylinder head failure. A cylinder head failure is caused by valve seats on cylinder #2 overheating. This is particularly common in Jeep Wranglers. However, depending upon your vehicle’s year and mileage, this problem is potentially covered under an extended warranty.


  1. Pentastar 3.6L Engine Problem:  Ticking Sound in the Engine

If you hear a ticking sound in your Chrysler, Jeep, or Dodge, it’s often a symptom of a 3.6 Pentastar rocker arm failure, also known as a cam follower failure. Although the cost of the parts isn’t too steep, this problem requires a highly experienced auto technician to repair, so the labor costs can drive the price up. 


  1. 3.6L Pentastar Engine Problem: Overheating

If your engine is overheating, or if you’re having problems with coolant leaks, heating problems, or a/c problems it’s possible you have a cooling system failure. This is due to a water pump or radiator problem that is preventing the coolant from properly flowing through the engine the way it should. In some cases, this may also prompt a check engine light, or a default code, depending on your vehicle.


  1. 3.6L FCA Pentastar V6 Engine Problem: Tapping, Knocking, Rattling

Tapping, knocking or rattling in your 3.6 Pentastar engine may be a symptom of an oil pump failure. However, before you panic, these noises may not indicate a complete failure, but instead are warning you of a drop in oil pressure. This can happen for a variety of reasons, but it is often due to sand deposits left behind in a cylinder head. Our expert technicians at Nerger’s Auto Express will be able to quickly diagnose and repair problems with your oil pump.
