Crown hybrid electrical issues

I'm seriously bummed. My 2022 Toyota Crown hybrid is acting up with 155193 km on it. The battery seems totally dead. I keep getting an error message, the lights are all weak and flickering, and the car struggles to start. Plugged in an OBD scanner and got an error stored related to low voltage. Could it be just a bad battery or something worse with the electrical system?

A 2022 Toyota Crown hybrid with 155,193 km is experiencing electrical issues, including a dead battery, weak and flickering lights, and starting difficulties. An OBD scanner indicated a low voltage error, suggesting a potential problem with the battery or electrical system. A similar issue in another vehicle was resolved by replacing a faulty battery sensor, which was confirmed to be the cause in this case as well. Replacing the defective sensor resolved the issues, restoring the vehicle's functionality.

Whoa, that sounds rough! Had similar happen with my 2018 Volvo XC60, though not a hybrid. Symptoms were close – dimming lights, weird error codes, sluggish starts. Checked all the usual suspects like battery terminals and charging, but nothing obvious. Turned out to be a faulty sensor messing with the battery management system. Could that be it in your Crown?

Interesting... a faulty sensor? Where was the sensor located on your Volvo, and how did you figure out that was the issue? Was it expensive to fix?

On the Volvo, it was a battery sensor integrated into the negative terminal cable. Honestly, I only found out when the dealership diagnosed it. I tried messing with the battery and all the usual checks, but no luck. I'd suggest getting yours checked out by a pro. Could save you a lot of headache, and potential damage to the hybrid system. Don't want to mess with that!

Thanks for the advice! I took it to a local shop, and you were spot on! The battery sensor was defective, causing all the issues. They replaced it for 315€. Runs like new now!
