The new Mazda6 Atenza still has some issues, but it's much better compared to the old version. As for the abnormal noise problems, the 4S stores are quite proactive in resolving them, and all reported issues have been addressed. More relevant information is as follows: Introduction: The new car has a body size of 4870mm1840mm1451mm, with a wheelbase of 2830mm. The new car is a mid-size sedan, and its long wheelbase provides ample passenger space. Exterior: The new car features a large front grille adorned with dot-matrix elements. The lower bumper and the headlight clusters on both sides are connected with chrome strips, creating a strong visual impact. The rear of the new car adopts a continuous chrome trim, and the taillights have been smoked.

As a seasoned mechanic with decades of driving experience, I've handled numerous cases involving 2021 Mazda6 (Atenza) owners. The primary source of rattling issues stems from the B-pillar area, which was indeed prominent in the 2019-2020 models due to body welding design flaws. For the 2021 model, Mazda officially claims to have implemented optimizations, such as reinforced structural adhesives, with many owners reporting reduced or completely eliminated rattling. However, sporadic reports still emerge during actual driving, especially after long-distance bumpy rides, where some vehicles develop minor noises in door panels or the dashboard. I strongly recommend test-driving on rough roads before purchase to listen for subtle sounds. Routine maintenance should also include checking bolt tightness and preventing dust buildup that could cause friction. If noticeable rattling occurs, promptly visit the dealership for adjustments or part replacements—safety first. Overall, the 2021 model shows significant improvements, but no car is perfect, and individual variations exist.

As an owner of a 2021 Mazda6 Atenza, I've been driving it for over half a year now. Initially concerned about the rattling issues, I specifically test-drove it on several laps of bumpy suburban roads. When brand new, there was a slight clicking sound from the B-pillar, especially when going over speed bumps, though it wasn't constant. After reporting it to the dealership, they made simple adjustments to the door hinges and interior trim panels, and the noise disappeared. Now the overall driving experience is much more comfortable, with no noticeable rattling during daily commutes on highways or city roads. From what I understand, many 2021 model owners have had similar experiences, with significantly reduced rattling frequency, likely because Mazda has addressed this long-standing issue. I recommend checking the vehicle history report, maintenance records, and road test results when purchasing. Regularly cleaning the interior to reduce vibration noise buildup also helps prevent minor issues from becoming serious.

From a professional automotive review perspective, the 2021 Mazda6 (Atenza) shows significant improvement in rattle control. The previous model's issues stemmed from body rigidity and welding processes, with B-pillar areas prone to looseness. The new version employs optimized techniques like tighter assembly and material upgrades, with many real-world tests showing no noticeable abnormal sounds. However, consumer reports indicate minor rattles still occur in a few vehicles under high loads or harsh road conditions—not safety-critical but annoying. Detail-oriented buyers are advised to conduct thorough test drives and check vehicle history data. For maintenance, keep interiors clean to prevent new noise sources from loose items. Overall, this model proves reliable with rattles no longer being a primary complaint point.

As a young office worker, I thoroughly researched the cost-performance ratio and issues of the 2021 Mazda6 Atenza before buying a car. The rattling noise was a major problem in the 2019 model, but feedback in the 2021 model user forums has significantly decreased, suggesting that Mazda has upgraded its production processes. During my test drive of the new car, I repeatedly tested it on bumpy roads and hardly heard any B-pillar rattling. However, a friend bought a used car and noticed slight door panel noises, which they said were lingering old issues. If you're on a tight budget, opting for a new car is safer—just make sure to check the door interior bolts and whether the trim is loose. In daily use, avoid slamming the doors or accelerating sharply over rough areas to prolong the vehicle's lifespan.
