2008 Dodge Journey 2.0L Diesel · KK08 CMU

Early Dodge Journey models were originally engineered with undersized 294mm front ventilated brake discs that struggled to dissipate thermal energy generated when stopping this 1.9-tonne seven-seater. Under sustained braking on UK motorways or during hilly driving, excessive heat cycling causes rapid lateral runout and disc thickness variation. The warped rotors induce severe steering wheel shaking and brake pedal pulsation, prompting Chrysler to eventually release a heavy-duty brake upgrade kit with larger calipers and discs.

In seven-seat Journey models equipped with rear cabin climate control, aluminium coolant and air conditioning pipes run along the exposed vehicle underbody above the rear suspension to feed the rear heater matrix and evaporator. Exposed to British road spray and corrosive winter road salt, the thin-walled aluminium lines pit and oxidise near their mounting brackets. This leads to pinhole coolant leaks causing engine overheating, or loss of air conditioning refrigerant, leaving the rear passenger compartment without heat or chilling.

The 2.0-litre CRD diesel model employs a dual-mass flywheel (DMF) to dampen torsional vibrations from the high-torque Volkswagen Pumpe-Düse engine. Due to the Journey's considerable vehicle mass and frequent family towing or urban stop-start duties, the internal DMF springs and friction damping plates wear out prematurely. Excessive rotational play leads to metallic chattering at idle, clutch pedal pulsation, and clutch plate slipping under high torque demand in fourth and fifth gears.
