2024 Silverado turn signal

I have a 2024 3500 silverado and my turn signal lights have gone out several times now. When I shut the truck off and restart they usually reset and work fine for a few days. But I bought this truck to pull my trailer and so far every time I'm pulling the lights start acting up. No turn signals and now I've noticed the brake lights don't always work. This is dangerous!! My husband and I own 8 different trailers and it seem the lights aren't working on any of the trailers when we pull with the 2024 Chevy. But my husbands ford truck works just fine, the brakes and turn signal lights work just fine. My son has a dodge and also helps us pull sometimes.. lights work fine on the dodge as well.
