Fiesta electrical issues

Hi, I'm experiencing some weird electrical issues with my 2021 Ford Fiesta gasoline. It has 126982 km. I'm getting sporadic errors in driving mode and the error lamps are lighting up randomly. Sometimes various systems, mostly audio/navigation, just fail. Also, the control units temporarily shut down, becoming unresponsive. I've checked the error memory and there is error stored. Anyone experienced something like this?

Sounds familiar! I had similar gremlins in my Fiesta. Almost like the car's having a mini-stroke. Was it just a one-time thing, or is this happening frequently?

It's happening more and more often. First it happened only once a month, now it happens almost every time I drive the car. Did you manage to fix it? What was the issue?

Yeah, it was driving me crazy. Turned out to be a defective cable connection to the BUS system to the control unit. Think of it like a loose wire in your computer – everything goes haywire. I would recommend going to the workshop, and ask them to check this specific connection.

Thanks for the tip! I took it to the workshop, and you were right. The mechanic confirmed that cable connection of the control unit was defective. Cost me 155€ to repair, but now it seems to be working as expected.
