Onix starting issues

I'm having a weird issue with my 2016 Chevrolet Onix, 1.0 gasoline engine. It's got 114286 km on it. Sometimes it won't start at all, other times it just shuts off while driving, and occasionally runs really rough. I've checked the usual suspects like battery connections and tried wiggling the ignition key, but no luck. Could a defective fuse cause such a spectrum of symptoms?

Summary of the thread

A 2016 Chevrolet Onix with a 1.0 gasoline engine experienced starting issues, occasional stalling, and rough running. Initial checks of battery connections and ignition key manipulation did not resolve the problem. The symptoms, including a flickering dashboard light, suggested a faulty ignition switch rather than a defective fuse. After professional diagnosis, the ignition switch was confirmed as the issue and was repaired, resolving the problem.

Sounds like a dodgy ignition switch, though rough running is less typical. Does the dashboard light flicker or go out when it stalls? Have you checked the ignition coil or starter motor relay?

The dashboard light does flicker sometimes when it stalls. I haven't checked the ignition coil or starter motor relay, as I'm not entirely sure where to locate them on this model. Is there a specific fuse that usually handles the ignition switch, or would that be a different circuit?

The flickering dashboard light points to the ignition switch. While a fuse could be the culprit, a failing switch is more likely given the symptoms. Best to get it properly diagnosed at a workshop. Could save you from unnecessary parts replacements.

Thanks for the advice! Took it to a local shop, and it was indeed the ignition switch. Total repair cost was 52€. Really appreciate the help!
