Lexus UX Terminal 30 Issue

Hey, I had a similar problem with my UX a while back. It sounds like a power supply issue. Have you checked for any voltage drops or shorts in the charging system? It might also be worth inspecting the fuse box for corrosion or loose connections.

Thanks for the reply. Could you elaborate on what you mean by voltage drops? Where exactly did you experience those issues on your UX?

Yeah, no problem. The voltage drop was noticeable when starting the car. The lights would dim excessively, and it struggled to turn over. I'd recommend having a workshop do a proper diagnostic check, mine ended up being a weak battery in the end.

Understood. I appreciate the insight. I took it to the shop, and it turned out to be a defective battery, as suspected. Repair cost was 290€.
