Seat Leon Hybrid Start Stop Problem

I'm having trouble with my 2021 Seat Leon hybrid. The start-stop system has stopped working. There's a warning light and the error memory shows a fault. The engine shuts off in Eco mode, but never restarts automatically. I've read a discharged battery can cause this, especially in hybrids. My car has 175853 km on it. Any ideas before I see a mechanic?

Sounds familiar. I had a similar problem with my Leon, though mine wasn't a hybrid. The start-stop was erratic, and the engine would cut out at lights, which was really annoying. Did the starter motor seem to struggle at all when starting? Checking the battery is a good first step.

When your Leon had this issue, was it intermittent or constant? Was there an error stored? Trying to gather as much information as possible before going to the workshop.

In my case, the problem became more frequent. At first, it was intermittent, but eventually, it stopped working completely. Yes, there was an error stored about low voltage. I'd recommend getting the battery checked soon. Maybe check it yourself with a multimeter, but a workshop visit is probably best.

Just letting you know, the workshop visit confirmed the battery was the issue. A replacement cost 290€, and now the start-stop system is perfect. Eco mode is running and the engine starts smoothly. No more warning light!
