Toyota Prius Electric A/C Compressor Failure Malaysia
Prius electric compressor uses POE oil — wrong oil destroys the compressor. Failure signs and genuine vs aftermarket replacement cost.
Prius electric A/C compressor is driven by HV battery — it's extremely durable because it has no mechanical clutch or belt. Expected lifespan: 200,000+ km. Preventive tip: run A/C for at least 5 minutes per week to keep the refrigerant circulating through the compressor seals.
Compressor Details
- No belt to replace — one less maintenance item vs conventional car
- Use HV-safe PAG oil (not standard PAG) if compressor is serviced — wrong oil damages motor windings
- Electric compressor replacement: RM 1,500–2,500 — rare failure; usually only after 200,000+ km
