Peugeot 3008 transmission issues

Hey, I'm having issues with my 2023 Peugeot 3008 Hybrid. It has 103101 km on it. The automatic transmission is acting weird. I'm getting implausible shifting, the transmission light is on, and sometimes it just won't shift right. Once, it even went into emergency mode! Anyone else experienced this?

Whoa, that sounds rough! I had a similar problem with my 2018 Volvo XC60, though it was a while back. I got weird shifting and the car felt like it was stuck in a gear. Did you check the voltage of your car battery? In my case it turned out to be undervoltage and the car computer was acting strange because of it. Do you have a way to read the error codes?

Undervoltage, huh? That's interesting. I haven't checked the voltage, to be honest. Where do I even start? I don't have a code reader myself. Could that really mess with the transmission like that?

Yeah, it sounds crazy, but modern cars are so reliant on consistent voltage that even a slight dip can cause all sorts of seemingly unrelated issues. If you don't have a reader, honestly, I'd suggest taking it to a workshop. They can properly diagnose the problem. In my case it was the undervoltage and I got a new battery.

Thanks for the tip! I took it to a workshop, and they found the transmission oil was worn out due to the undervoltage. They replaced the oil and fixed the undervoltage issue – cost me 240€ Appreciate the help!
