Gdi System Concerns:
Carbon buildup in intake valves and on piston tops due to GDI design; potential for fuel injector issues, high-pressure fuel pump wear. Requires specific cleaning procedures.
Timing Belt Tensioner:
Tensioner failure can lead to premature belt wear or snapping. Regular replacement along with the belt is crucial.
Suspension Components:
Wear in bushings, ball joints, and tie rod ends are common due to typical SUV usage and potential off-road excursions.
Exhaust Catalytic Converter:
Can become clogged, especially in GDI engines with carbon issues, leading to reduced performance and increased fuel consumption.
Electrical Connectors:
Corrosion or looseness in electrical connectors, particularly in wheel speed sensors for ABS and grounds, can cause intermittent faults.
