I recently bought a 2017 Colorado and when I called and the recipient answers they all tell me that they hear a high pitch noise, and it then gradually slows down but remains in the background. Now, I have noticed that when i turn my headlights, on/off or switch from Auto to Manual on that **** the noise is more or less.

Should I take it in to check, or perhaps this is something within the software of either my phone or the trucks?
I use an iPhone and have the latest software update. iPhone 7.

 

I'm experiencing this very problem. i just dropped off my truck at the dealership with hopes that they can fix this. I'm not too optimistic based off the service staff's expression when describing the issue...
I'll keep you posted.

 

I have the same problem I called the dealer and that was no help

 

All the new vehicles are having bugs with bluetooth rn;
so are the other makers

 

Just took delivery of a new Colorado on Monday, stopped by dealership yesterday because of this same problem. They said they had never heard of this has anyone had any luck with getting this fixed yet?

 

See the fix for this...mine goes to the dealer tomorrow with same issue. I just bought mine in January 18

Update - Chevy Service Bulletin #17-NA-377 was performed to reprogram the radio on my truck today and that fixed the noise problem.

 

good to know!
thanks
