During the first maintenance period, you can go directly for the first maintenance or visit a 4S store to have them help resolve the issue. Below is relevant information about Mazda: 1. Introduction: Mazda, officially known as Mazda Motor Corporation, is a Japanese multinational automaker listed on the Tokyo Stock Exchange (TYO), ranking 400th in the 2020 Fortune Global 500. 2. Main Models: As of 2021, Mazda's global passenger vehicle lineup includes: SUV series CX-3, CX-30, CX-4, CX-5, CX-8, CX-9, MX-30; sedan series Mazda2, Mazda3, Mazda6 (known as "Atenza" by FAW Car); and the sports car MX-5.
I've been driving my Mazda for several years, and last month the triangular window on the C-pillar started squeaking, which is really annoying. The main issue is the aging seal strip—when the rubber deforms and cracks, it rubs against the window edge and makes noise. Another problem is the loose internal clips, which vibrate even more on bumpy roads. I temporarily fixed it by adding lubricant myself, but later realized the root issue wasn’t resolved. I recommend not tinkering with it blindly and instead taking it directly to a 4S shop or professional repair shop to check the fasteners. This can prevent the noise from affecting your driving mood, especially during long highway trips where the buzzing can hurt your ears. For regular maintenance, periodically inspect these rubber components and replace them promptly when they age to extend their lifespan.
As a car enthusiast, the common causes of Mazda C-pillar quarter window rattling are design and assembly issues. This quarter window is fixed to the C-pillar, and over time the sealant can shrink or crack, creating gaps between the metal frame and glass that cause friction noise while driving. In some models, loose internal retaining springs or dust buildup can also cause this issue—my friend's older model was fixed this way after disassembly. Mazda cars have strong sporty characteristics, and components often suffer from vibration impacts. I recommend getting a comprehensive inspection at a service center—don't ignore small issues, as they might reveal other hidden problems. Regular car washes to remove dust also help with prevention.
