The driveshaft on models with 2.0L or 3.3L engines and all-wheel drive can fracture at its weld seam, cutting power to the rear wheels or allowing the vehicle to roll away in Park. The right-side motor mount fasteners can loosen over time until the axle disconnects from the engine entirely, causing loss of drive power. The automatic transmission's park pawl can engage while the vehicle is moving, damaging the park system and creating a rollaway risk.
