Lexus LS Battery Sensor Issue

I'm having an issue with my 2015 Lexus LS with a gasoline engine. The battery is heavily discharged at 108160 km. I'm getting an error message in the speedometer, weak and flickering lights, and a weak battery when starting. Error codes are stored. Could this be the battery sensor?

Sounds like a classic case of battery failure! Is it the original battery? How old is it? And did you check the battery terminals?

The battery was replaced three years ago. Terminals look fine. But could a defective battery sensor really cause all these issues?

Yep, that sensor is a known culprit for weird electrical gremlins in those LS models. Can cause a parasitic drain and the other symptoms you're seeing. I'd recommend a workshop to verify.

Thanks for the confirmation. The workshop diagnosed a defective battery sensor. Repair cost was 315€. Problem solved.
