Lexus UX Ignition Problems

My 2020 Lexus UX gasoline, 174368 km, has an ignition problem. Sometimes it won't start, occasionally shuts off while driving, and runs rough at times. Suspect a defective fuse. Thoughts?

I had similar issues with my UX. Does the dashboard light up normally when you turn the key, or is it dim/flickering? Have you checked the battery terminals for corrosion?

Dashboard lights are normal. Terminals are clean. Is your UX the same year? Did you find a specific fuse that was the culprit?

Mine's a bit older, but similar symptoms. No specific fuse identified. After troubleshooting, I took it to a workshop. Definitely get it checked soon to avoid getting stranded.

Thanks. Turned out to be a faulty ignition switch fuse. Replaced it, cost 52€. Seems fixed now.
