Tahoe reduced engine power

Hey, I'm having some trouble with my 2017 Chevrolet Tahoe with a gasoline engine. It's got about 160834 km on it. Recently, I've been experiencing reduced engine power, a warning light on the dash, and it's starting pretty rough. Also, the lights are flickering sometimes. I scanned for codes and there's an error stored. I'm suspecting it might be the generator. Has anyone else run into something like this?

Sounds familiar. I had similar issues with my Tahoe. Weak lights, engine misfire at times. Check your serpentine belt, but it's probably the alternator going bad.

Thanks for the quick reply! When your alternator went, were the symptoms pretty consistent, or did they come and go? Did you have any trouble starting it?

They started intermittently, then became more frequent. Eventually, it got to the point where the car wouldn't start at all some days. I'd get it checked out at a reputable shop.

Appreciate the advice! I took it to my mechanic, and you were spot on. It was the generator. Cost me 960€ to get it replaced. Thanks again for pointing me in the right direction!
