Question 1

Totally Integrated Power Module (TIPM) failure (Grand Cherokee WK2)

Accepted Answer

The TIPM on the Grand Cherokee WK2 can fail, causing a no-start, the fuel pump running continuously or not at all, the horn sounding by itself, and wipers or lights acting on their own. Common on 2007-2014 Chrysler, Dodge and Jeep vehicles, with some recalls and extended warranties.

Question 2

Monostable gear shifter rollaway risk (2014-2015)

Accepted Answer

The electronic monostable shifter in the 2014-2015 Grand Cherokee returns to center after each selection, making it easy to leave the vehicle out of Park. Rollaways led to a recall that added an automatic Park feature.

Question 3

Oil filter housing / oil cooler leak (3.6 Pentastar)

Accepted Answer

The plastic oil filter housing with integrated oil cooler on the 3.6 Pentastar cracks or its gaskets fail, leaking oil (and sometimes coolant) into the engine valley. Signs are a burning oil smell, drips at the back of the engine and a dropping oil level.

Question 4

Rocker arm failure on the 3.6 Pentastar (2011-2013)

Accepted Answer

Early 3.6 Pentastar V6 engines can suffer a seized rocker arm roller that wears the camshaft, causing ticking, misfire and a check engine light. Some 2011-2013 engines also had left cylinder head valve seat problems, covered by an extended warranty.
