I had my 5 week old truck in for service to see if they can fix the chirping and my non-functioning wireless charger and they clearly were familiar with the chirping issue. The service manager mentioned they heard replacing the "Y" portion of the exhaust makes the chirping go away but it is not covered by any warranty etc because as far as they are concerned it is normal. Has anyone tried this before, if so has it worked?
I'm up in Canada so the chirping noise gets worse (and lasts longer) the colder it gets and is driving me nuts, and I am definitely tired of people asking me what is wrong with my truck. My co-worker has a 2020 Big Horn with the same issue but my 2021 definitely is louder than his, sucks spending over $90k on a truck and it sounds like my old Dodge Shaddow I had for my first car.
