NHTSA Complaint #11429312 — 2019 MAZDA CX-5

Oftentimes when driving at speeds of approximately 80mph or more, a loud whining/whistling noise appears. It appears to be coming from the area of driver side front door, passenger side front door, both front doors simultaneously. The issue has an earlier onset in the presence of crosswind, or headwind. I was able to record several videos where the noise can be heard very clearly. Some of these videos have been posted online: https://vimeo.com/547826873 https://vimeo.com/manage/videos/580602909 and the links have been shared both with my local Mazda dealership (Oak Tree Mazda by DGDG in San Jose, CA: 4250 Stevens Creek Blvd, San Jose, CA 95129) as well as with Mazda of North America. However, my complaints have been ignored as the dealership keeps stating that they are "unable to duplicate problem". There are several threads on two Mazda owners forums that describe this very issue with Mazda CX-5 in USA, Canada, as well as in Europe. This video from an owner in Germany shows the very same issue: https://www.youtube.com/watch?v=zykyoCIsItc&t=204s https://www.mazdas247.com/forum/index.php?threads/2019-cx-5-signature-whistling-noise-on-highway-or-high-speeds.123868506/page-2#post-6727077 https://www.mazdaworld.org/threads/cx-5-2018-version-high-pitched-squeal-whistle-like-noise.337073/#post-754625 According to one of the forum members, a Technical Service Bulletin (TSB) R084/20 to address this issue has been issued by Mazda in Europe and Russian. The root cause has to do with door trim seals. Under the "CASUE", this TSB reads, "When driving under following conditions, a negative pressure generated on the doors pulls them outside. The counterforce exerted by the weatherstrips mounted on the doors is lower than the sucking force, resulting in weatherstrip vibration. -The vehicle is exposed to a side wind while driving at a speed higher than 160km/h -The vehicle is exposed to a strong side wind while driving at a speed higher than 120km/h."
