Known problems

Wear item

Charging system: battery and alternator

The alternator charges the battery while the engine runs and powers everything electrical. Both are consumable parts with a service life, and on a used car at least one of them has usually been replaced already — or is due.

Air conditioning compressor failure

The compressor is the pump in the air conditioning loop. When it seizes it can send metal debris through the whole system, which turns a component replacement into a system job.

Suspension and steering noise

Bushings, ball joints, link rods and strut mounts are rubber and grease components that wear continuously. They rarely fail suddenly; they get gradually noisier and vaguer, which is why a test drive on a rough road tells you more than one on smooth pavement.

Carbon buildup on intake valves

In a direct-injection engine the fuel is sprayed into the cylinder rather than at the intake valve. Nothing washes the back of that valve, so deposits from crankcase ventilation and exhaust gas recirculation accumulate there over time.
