Signs: Coolant traces or dried pink crust at the pump, falling coolant level, sweet smell
Fix: Inspect the pump weep hole and seal; replace the pump and refill with Toyota long-life coolant
Signs: 'Engine Maintenance Required' message, codes P2681 (P268111 / P268115), small coolant leak at the valve, odd air-conditioning behaviour
Fix: Ask a Toyota dealer by VIN about a service programme; otherwise replace the valve / bypass hose with the updated part
Signs: Check engine light with P26CA14 / P26CA31, coolant leak at the pump, temperature warning
Fix: Stop if the temperature rises; replace the electric pump per Toyota's bulletin, check warranty cover first
Signs: Check engine light with P0A80 or P0A7F, fan noise from the rear seat area, battery runs hot and wears faster
Fix: Remove and clean the battery fan and air duct, clean or replace the intake filter; check the battery itself if the codes return
Signs: Check Hybrid System warning with P0A80, engine runs more often, less electric assist, fuel use up
Fix: Have the battery tested (Toyota Hybrid Health Check); replace the pack with a new or quality reconditioned one, and clean its cooling fan at the same time
