CHR Hybrid Electrical Issue

Hey, I'm having a weird electrical issue with my 2017 Toyota CHR hybrid. It's got about 36455 km on the clock. The car starts poorly. It seems like Terminal 30 is getting continuous plus interrupted power, leading to a heavy battery discharge. I suspect a voltage drop somewhere, maybe a wiring harness issue or even a short circuit affecting the starter motor. Has anyone run into something similar? Any thoughts on where to start looking besides the obvious battery check?

Whoa, that sounds familiar! I had a similar problem with my CHR. Was getting seriously frustrating. Is your battery draining even when the car's off?

That's exactly what's happening! The battery drains even when the car is off. What did it end up being in your case? Any specific areas I should be checking?

Yep, sounds like the same gremlin! In my case, it ended up being a faulty component that was drawing power even when it shouldn't. Honestly, I ended up taking it to a workshop because tracing the short was a nightmare. Best 290€ I ever spent. They said it was a defective component causing a short circuit.

Thanks a bunch for the info! Sounds like chasing it myself might be more trouble than it's worth. I'll take it to a trusted mechanic. Appreciate the head's up!
