Volt Lighting Issues

Having issues with my 2014 Chevrolet Volt hybrid. The car lighting is acting up - lights switch on seemingly at random, and I'm getting an error stored. I suspect a faulty light switch, possibly a defective cable or plug connection. Anyone else experienced this? Already checked the fuse box, all looks ok. Mileage is 135642 km.

Sounds familiar. I have a Volt too and had a similar gremlin in the lighting. Did you check the tail lights specifically? Sometimes a short there can cascade weirdness back to the switch.

Yeah, checked the tail lights as well, all bulbs are fine. You had the exact same symptoms? Did the error code point to anything specific?

The symptoms were spot on, yeah. The error code was vague, something about 'lighting circuit malfunction'. I ended up taking it to a workshop since I lack the proper diagnostic tools. They narrowed it down to a bad connection in the switch harness. Cost me 95€ to fix.

Thanks for the info. I'll take it to a reliable shop and have them check the harness connection like you said. Hopefully, that's the culprit and it's a quick fix.
