Thanks. Can you explain how you diagnosed the charging system fault and if you had any circuit breaker or ignition switch problems?

The battery kept draining overnight. A parasitic draw test showed a faulty voltage regulator in the alternator. I'd get a professional opinion. The repair cost me 290€.

Thanks for the info. I'll schedule a workshop appointment for a charging system diagnosis.

I have a Lexus LS too. I had a similar starting problem that turned out to be a faulty charging system. Have you checked the alternator output and the wiring harness to the battery? Also, check the starter motor circuit.
