Maintaining a car that is rarely driven

A car that is rarely driven (working from home, second car, long lay-up) faces different stresses than regular use. Some parts wear little by mileage but age or deteriorate when idle. Here is what to watch.

Battery

The battery discharges when idle (parasitic drain, alarm, electronics). After several weeks without driving, it may be too weak to start. Regular charging (maintainer or short run) or disconnect the negative if stored long-term. If the battery is over 4–5 years old, have it checked.

Tyres and fluids

Tyres: rubber ages (cracking, loss of elasticity) even without mileage wear. Check pressure before driving again. Fluids: oil level, coolant, brake fluid. Oil changes are also by time (e.g. once a year): follow the service book.

Brakes and starting

Brakes: corrosion of discs and calipers when idle, especially in damp weather. When you start again, a slight squeal may go after a few brakes; if rust is heavy, have them checked. Starting and driving at least 15–20 minutes every 2–3 weeks limits battery discharge and keeps fluids moving. My Auto Check-up helps you keep track of maintenance.
