2021 Buick Envision Avenir
Greetings! I own a 2021 Envision Avenir. it has a rattle/ flapping noise coming from the lower right of the interior, noise starts around 55 MPH and get worse with speed. this has been happening since the car had 1,000 miles on it, it now has almost 14,000. dealer is unable to locate this noise. additionally, the driver seat developed a metallic scraping noise around 7,000 miles. I have video evidence of both noises but the dealer seems uninterested/ annoyed with me. I took the service manager on a test drive and was able to reproduce both noises but was told there is nothing they could do without "tearing my car apart" I'm hoping someone can help!
