Lexus LX Undervoltage Error

Interesting, I had a similar thing happen with my LX. It was a pain to diagnose! Did your mechanic check the ECU diagnostics and fault codes? In my case, it was definitely tied to some weird electrical gremlins. Did the error pop up after any recent work?

No recent work, just normal driving. What kind of electrical gremlins did you experience?

Basically, the computer system was acting up and throwing a bunch of codes. It did indeed point to undervoltage. To be honest, it's probably best to have it checked out by a professional. Could be a minor fix, could be something more serious.

Thanks, I appreciate the insight! Took it to a shop and it was indeed undervoltage. Cost 240€ to repair.
