Question 1

Uconnect 12-inch screen delamination (Ram 1500 DT)

Accepted Answer

The 12-inch Uconnect touchscreen on some 2019-2021 trucks can delaminate or bubble, leading to ghost touches and unresponsive areas. A screen replacement under warranty or extended coverage is the usual fix.

Question 2

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 3

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.
