Known problems
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.

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.

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.

A turbocharger runs at very high speed on an oil-fed bearing, driven by exhaust gas. Its condition is tied directly to the engine's oil history, which makes service records more informative here than on most components.
