The cost varies by condition. Used 1NZ-FXE units typically cost £400-£900, reconditioned engines £1,200-£2,200, and fully rebuilt units £2,000-£3,500 supply-only. For the newer M15A-FXE engine, prices are slightly higher: used from £500, reconditioned from £1,400, rebuilt from £2,200. Fitting adds 6-8 hours of labour at UK specialist rates (£390-£520). Always confirm the hybrid system calibration is included.

The most common signs are engine overheating, white smoke from the exhaust (coolant burning), loss of coolant without external leaks, and milky oil from coolant contamination. Some early 2012-2014 1NZ-FXE engines are more prone to this issue. If you notice any of these symptoms, have the cooling system and head gasket checked immediately.

• White smoke from exhaust
• Loss of coolant without external leaks
• Milky oil (coolant contamination)

For a 2012-2017 Yaris 1.5 Hybrid worth £2,000-£8,000, a rebuilt engine at £2,000-£3,500 typically represents 25-50% of the vehicle's value - making replacement borderline on older examples but viable for newer or well-maintained cars. If the vehicle is worth under £5,000 and has other issues, evaluate scrap value first.

• 12-month warranty on rebuilt units adds peace of mind
• Specialist pricing significantly undercuts main dealer rates

The Yaris Hybrid's 12V auxiliary battery only charges when the car is in READY mode. Repeated short trips or leaving the car parked for extended periods can lead to a flat battery. This is the most common complaint on Yaris Hybrids and is easily fixed with a new 12V battery (£120-£200) - don't assume the main hybrid battery has failed.

• 12V battery charges only in READY mode
• Short trips = insufficient charge
• New 12V battery: £120-£200
