Common Issues to Watch For

Based on the 2018 LEXUS RC's fuel type, age, and engine size, these are the most likely problem areas to check.

Hybrid Battery Health

Watch out

After 8 years, hybrid battery capacity may have reduced. A full replacement costs £2,000-£4,000, though reconditioning is cheaper at £500-£1,500.

Inverter and Power Electronics

Medium risk

The inverter converts DC to AC for the electric motor. Failures are expensive (£1,500+) but relatively rare. Listen for unusual buzzing sounds.

Regenerative Braking

Medium risk

Brake discs can corrode from reduced use (the electric motor handles most braking). Surface rust is normal but deep pitting needs attention.

Suspension Wear

Medium risk

Shock absorbers, springs, and anti-roll bar links typically need attention around this age. Listen for clunks over bumps and check for uneven tyre wear.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
