Engine - Coolant Leaks (Water Pump/Thermostat Housing)

Coolant leaks from the water pump and thermostat housing are frequent issues, potentially leading to overheating and engine damage. Symptoms include visible leaks, low coolant levels, and a 'check engine' light. Estimated repair cost: $300 - $1,000.

Engine - Carbon Buildup (Intake Valves)

Direct-injected engines can suffer from carbon buildup on intake valves, impacting performance and fuel efficiency. This is a common issue for many modern direct-injection engines. Estimated repair cost: $300 - $600.

Engine - Oil Leaks (Camshaft Chain Tensioner/Valve Cover)

Oil leaks from the camshaft chain tensioner and valve cover gaskets have been reported, which can lead to more significant engine problems if not addressed. Estimated repair cost: $400 - $800.

Steering System - Intermittent Heaviness/Looseness

Some owners report intermittent heavy or loose steering, sometimes accompanied by warning lights. This can be related to the steering module, angle sensor, or other components. Estimated repair cost: $500 - $1,500.
