Maintenance & Reliability Notes
While Lexus is highly rated for reliability, this specific age (approx. 15 years) brings certain considerations:
Hybrid Battery: As the vehicle reaches this age, the hybrid battery may show signs of degradation. A “Check Hybrid System” light is the standard indicator.
Inverter Coolant Pump: A common failure point in early 450h models; ensure this has been inspected or replaced.
Oil Cooler Lines: Some 2011 models have rubber lines that can leak; many owners upgrade these to the newer all-metal versions to prevent sudden oil loss.
Brake Actuator: Listen for a “chirping” or “barking” sound when applying the brakes, which can indicate an aging actuator.
