Tundra Hybrid Reduced Engine Power

I'm having trouble with my 2022 Toyota Tundra hybrid. At 37965 km, it has reduced engine power. A warning light is on, it's hard to start, and the lights are weak and flickering. There's also an error stored. Could a bad generator cause this?

I had similar issues with my Tundra. Have you checked the charging system voltage? A big voltage drop could mean a faulty alternator. Also, check the serpentine belt for wear, since it drives the alternator.

Thanks. Could an engine misfire be related, or is that a separate issue?

A misfire could cause similar symptoms, but the weak lights and starting problems make the charging system more likely. If you're not sure, get the generator checked at a workshop.

Thanks for the advice. The workshop diagnosed a defective generator and quoted 960€ for replacement. Seems like that'll fix it.
