2023 Chevrolet Traverse UNKNOWN OR OTHER

When I took my car out my garage one afternoon, I heard a loud noise that my car was making from the outside of the vehicle. The sound was super loud and made my vehicle sound like a race car reving up, every time I pressed on the gas and then when I pressed on the brakes, it made a screeching/ rattling noise. Come to find out when looking underneath the exhaust pipe underneath the car is hanging off, looks like the mounting bracket separated. Then there was a big visible hole as well. I decide to take it to a mechanic shop and fix this myself and yet the dealership also says there is no recall for that issue. Another additional issue was I was having on this same vehicle was a weird smell coming from my A/C vents when I first turned on the vehicle to which it then dissipates . Informed the dealership and they said again, they don’t know why the car is smelling like humidity. They said they would call me back so they can take the car in, and this was over a month ago, never heard back either.

My alternator died 4 weeks ago. My mechanic can't find one anywhere. He was told GM does not make them for this model yet. I only have 50,000 mi and bought this vehicle brand new. I'm extremely disappointed! My three Young kids and I ended up on the side of the road which was more than a little scary
