Cronos Fault Memory Lock Active

My 2020 Fiat Cronos with a gasoline engine is throwing me for a loop. Mileage is only 24267 km. I'm getting a 'Fault memory lock active' message. All I know is that there is an error stored in the error memory. I'm suspecting it's probably undervoltage in the vehicle but I have no idea where to start looking. Has anyone else run into this?

A 2020 Fiat Cronos owner experienced a 'Fault memory lock active' message, suspecting an undervoltage issue. Another owner with a similar experience suggested checking the vehicle at a repair shop due to potential ECU faults. The problem was confirmed to be an undervoltage issue, which was resolved at a workshop.

Did this summary help you solve your problem?

Whoa, that sounds familiar. I have a Cronos too, and I had some weird electrical gremlins popping up. It also threw a similar error, something about a memory lock. Was yours difficult to start, or did you notice anything else acting up?

Interesting. No starting issues, though. Everything seems perfectly normal, except for this damn error. Do you remember exactly what was happening when it showed up for you?

I don't recall exactly, but the error kept coming back. I would seriously advise that you have it checked at a repair shop. An ECU fault can cause a lot of issues on these cars.

Thanks. I appreciate the insight. Just got it back from the workshop, turns out it was an undervoltage issue causing the memory lock. Cost me 240€ to sort it out. Lesson learned!
