2007 Dodge Caliber 2.0L Petrol · AJ56 ZNH

The Caliber's front suspension takes immense strain from the car's 1.4-tonne curb weight and stiff spring rates over British speed cushions and potholes. The rear voided compliance bushes of the lower control arms tear and debond, while the pressed-in lower ball joints develop excessive axial play. Worn arms cause front-end clunking over uneven surfaces, imprecise steering centering, and uneven wear on the inner edges of the front tyres, frequently resulting in an MOT refusal.

Petrol 2.0-litre Caliber models equipped with the Jatco JF011E continuously variable transmission (CVT2) are prone to fluid overheating and internal steel push-belt slip. Over extended motorway runs or under stop-start city driving, degraded NS-2 transmission fluid leads to high internal friction, triggering a high-pitched whining noise, shuddering under acceleration, and engagement of transmission limp-home mode. Many owners neglected scheduled fluid and filter replacement intervals, resulting in scored pulleys and catastrophic transmission failure.

The 2.0 CRD diesel engine is a Volkswagen-sourced 2.0 TDI Pumpe-Düse 16-valve unit (engine code BKD/ECD). The silicone rubber intercooler boost pipes—particularly the lower elbow near the front undertray—suffer oil vapour saturation and heat cycling, leading to longitudinal splits under boost pressure. Concurrently, the exhaust gas recirculation (EGR) valve and inlet manifold suffer severe carbon choking from short urban journeys, causing the variable geometry turbocharger (VNT) mechanism to stick and triggering sudden loss of power.
