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

Broken exhaust manifold bolts (5.7 HEMI)

Accepted Answer

Exhaust manifold bolts on the 5.7 HEMI commonly snap from heat cycling, causing an exhaust leak and a ticking noise that is loudest on cold start and fades as the engine warms up.

Question 4

Lifter and camshaft failure on the 5.7 HEMI ("HEMI tick")

Accepted Answer

The 5.7 HEMI is prone to roller lifter failure: the needle bearings seize and the lifter wipes the camshaft lobe. Symptoms are a persistent ticking, misfire and check engine light, often on engines with MDS cylinder deactivation and long idle times. The repair requires a new camshaft and lifters.
