Consumer Description

I have a really loud buzz & rattle noise. I can feel vibration on the passenger floor board real bad. The loud noise usually around 2,000-2,500 rpms. I have 39,000 miles on my car. It has always made a noise at take off but we thought it was normal untill now it's extremely worst. I took it into the dealship they diagnosed as something broken inside the muffler / resonator / weld inside muffler. So I did my research on the internet and I see alot of people complaining about this same issue on there cars. There was even a BULLETIN NUMBER (PIT5863) Pulished on 11/2/2021 the correction review # (21-na-118) all my issues are identical to bulletin. My year,make,model and issues with my car.
