Why does my hybrid engine keep starting on short trips?

Hybrids run the engine for four main reasons even when the battery has charge: cabin heat in winter, engine oil circulation, catalyst warm-up to keep emissions legal, and battery temperature management. It's normal — not a fault.

New hybrid owners often think the petrol engine is running too much. Here's why it's usually doing exactly what it should.

Should the engine run in EV mode? — It can — for the reasons above. If the dash actively says EV MODE and the engine still runs, that's a fault.

Is short-trip use bad for a hybrid? — Worse than for a pure EV — short trips don't let the catalyst stabilise. Try to take it on a 30-minute run once a week.
