Lexus NX Error Memory Lock

Hey, I'm having a weird issue with my 2017 Lexus NX with a gasoline engine. The error memory lock is active and I only get a message saying there's an error stored in the error memory. Has anyone seen this before? I've got 103694 km on the clock. Could it be something simple like a low battery? So frustrating!

A 2017 Lexus NX owner experienced an issue with an error memory lock, receiving only a message indicating an error stored in the memory. The problem was identified as being caused by undervoltage. The suggested solution was to have the vehicle's computer system diagnosed at a professional workshop, which confirmed the undervoltage issue.

Did this summary help you solve your problem?

I had a similar issue with my NX. Do you have any other symptoms, like the car acting strangely or any warning lights illuminated?

Interesting! No other symptoms at all, which is what's so puzzling. Just the error message about the memory lock. Was yours the same, just the error and nothing else?

Yes, that's correct. In my case it was undervoltage leading to a locked fault memory. I would suggest getting the computer system diagnosed at a professional workshop.

Thanks for the info! I had it checked out. Turns out it was indeed undervoltage. Repair cost was 240€. Appreciate the help!
