The main causes of rattling noises inside the 2020 Mazda Atenza or from the dashboard and center console are as follows: 1. Dashboard rattling: Gaps or misalignment between leather and plastic components can cause squeaking noises when squeezed on bumpy roads. Generally, locating the source of the noise and using materials like paper towels or rubber as spacers can help. 2. Center console rattling: This is usually caused by collisions between the car's speakers and other components. Tightening the screws to secure the speakers, CD player, etc., can resolve this issue. 3. Electrical current noise inside the car: This is typically more noticeable right after starting the car, especially during cold starts when audio or air conditioning systems activate immediately or automatically. The noise usually disappears naturally after the car warms up or has been driven for a while.

I was quite excited when I first drove the 2020 Mazda6, but after prolonged use, I noticed some rattling issues. The most common one is probably the creaking sound from the doors when opening, closing, or turning, which is mostly caused by insufficient lubrication of the hinges or loose screws during assembly. The interior is also quite annoying, such as the plastic rubbing sound near the dashboard on bumpy roads, or the noise from dust entering the large gaps in the center console. Additionally, suspension system noises are worth noting, like the clunking sound when going over speed bumps, which might indicate aging shock absorbers. While these issues don’t affect the car’s normal operation, prolonged exposure to such noises can be distracting while driving. It’s recommended to first visit a 4S shop to check the bolts and track lubrication, rather than waiting until it affects safety.

As an ordinary car owner with over a decade of driving experience, I find that the rattling issues in the 2020 Mazda6 (Atenza) mainly occur in the door panels and headliner areas. Door rattles are quite common, especially in northern winters when low temperatures cause metal components to contract and deform, resulting in more noise. Interior components like rearview mirror covers or storage compartments may produce clicking sounds when shaken, primarily due to insecure plastic part fastenings. Another issue is the clunking noise caused by loose suspension connection points, which becomes particularly noticeable on rough roads. While these noises don't pose direct threats to driving safety, prolonged exposure can be quite distracting. Don't take them lightly - it's best to regularly check for looseness in the car frame and interior gaps, and adding some rubber sound insulation pads where appropriate can help.

As a mechanic who frequently works on this car, I've helped many owners fix rattling issues. The common problems with the 2020 Mazda6 (Atez) include squeaky door frames caused by loose hinges or rusted fixing screws. For the interior, panels may rattle at connection points due to movement, and plastic materials tend to make friction noises from thermal expansion and contraction. Occasionally, there might be a clunking sound from the suspension system, possibly indicating worn bushings that need replacement. A simple DIY method is to gently press the door while parked to locate the sound source. However, the key solution is to visit a workshop for proper measurement and tightening. Avoid randomly spraying lubricants to prevent damaging electrical wiring. Regular maintenance can prevent most of these issues.
