Prisma Battery Sensor Issue
Summary of the thread
A 2017 Chevrolet Prisma is experiencing issues with a potentially failing battery sensor, indicated by slow engine turnover, weak and flickering lights, and fluctuating voltage. The voltage drops below 12.6V even when the engine is running, suggesting a problem with the charging system or the sensor itself. A similar issue was resolved by confirming the sensor as the culprit, leading to a recommendation to have a mechanic diagnose and fix the problem.

Thanks! I checked the terminals, they're clean. The voltage drops below 12.6V even when the engine is running. This makes me think it's the sensor. Did you see similar voltage drops? What did you do to fix it?

Yes, I saw similar voltage drops and flickering lights. Honestly, after checking the easy stuff like connections, I took it straight to a trusted workshop. They confirmed it was the battery sensor. From what I understand, it's not uncommon on these models.

Thanks for confirming! I'm taking it to my mechanic for a diagnosis and fix. Looks like it'll cost around 315€ to get it back in shape. Thanks again for the help!

I had a similar experience with my Prisma. The symptoms you describe are very familiar. Have you checked the battery terminals for corrosion? Also, what's the voltage reading when the engine is running? That might give us a better indication of whether the alternator is charging correctly or if the sensor is truly the culprit.
