After testing, the all-new Mazda6 has completely resolved the rattling issue. Here are the relevant details about the Mazda6: Exterior Design: Drivers can see the large-sized grille, the dot-matrix middle net design, and the eagle-eye-like headlight clusters. However, compared to the 2020 model, the height of the new model has been adjusted from 1445mm to 1451mm, while the length, width, and wheelbase remain unchanged. Interior: The 2021 Mazda6 also follows the layout of the 2020 model. According to the official website, the car will feature materials such as Hokkaido Ash Wood, Ultrasuede Nu fabric, and Nappa leather, further enhancing the premium feel of the materials used.

As a long-time Mazda owner, I've been following the rattling issues with the Atenza for several years. The 2020 batch did experience widespread B-pillar rattling, and the manufacturer later issued a technical bulletin. The root cause was resonance noises due to insufficient welding strength of the body panels, particularly noticeable on uneven roads. The solution was quite straightforward - reinforcing the body frame welding points and adding damping blocks to absorb vibrations. The newer Atenza models rarely report similar issues now, but existing owners should remember to get their vehicles serviced promptly. By the way, excessive tire pressure or aging suspension bushings can also cause rattling noises, which fall under routine maintenance - worth checking during inspections.

Last year, my Mazda6 had its B-pillar rattle issue resolved. The 4S shop first test-drove to locate the noise source, then used professional equipment to generate vibration waves inside the cabin to identify loose points. The repair plan involved three steps: reinforcing the trunk hinge structure, adding cushioning foam to the roof crossbeam, and finally filling soundproofing adhesive into the door seals. The entire process took two days, with material costs fully covered by the manufacturer. The most noticeable improvement was an 80% reduction in rattles on rough roads, though occasional slight friction noises still occur in winter cold. Given the complex causes of body rattles, it's recommended to also inspect the sunroof rails and seat brackets during repairs. During routine maintenance, have technicians tighten chassis bolts to prevent new rattles from developing.
