Common Issues to Watch For
Based on the 2021 LEXUS CT's fuel type, age, and engine size, these are the most likely problem areas to check.
Hybrid Battery Health
Medium riskAfter 5 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
Low riskThe 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 riskBrake discs can corrode from reduced use (the electric motor handles most braking). Surface rust is normal but deep pitting needs attention.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
