What is the solution for the abnormal noise in the Mazda Atenza's B-pillar?
3 Answers
Mazda Atenza's B-pillar abnormal noise is caused by damage to the clutch bearing shaft. Below is an introduction about the Mazda Atenza: 1. Appearance: It adopts Mazda's latest "Kodo" design language, featuring a "U"-shaped front face and LED headlights. The new model's headlight assembly includes LED daytime running lights. 2. Configuration: As Mazda's new generation flagship model, one of the Atenza's major highlights is the application of Mazda's Skyactiv Technology. Compared to traditional naturally aspirated engines, the Atenza's Skyactiv engine boasts a high compression ratio of 13:1, improving fuel economy and torque by 15% each.
Last time I took my Mazda6 through a high-speed corner, the B-pillar started making cracking noises. After spending half a day at the repair shop, we finally figured it out. The mechanic used a stethoscope to locate the issue at the seatbelt height adjuster position. Upon disassembly, we found it was caused by friction between the metal bushing of the sliding rail and plastic components. Spraying some silicone-based lubricant into the track immediately silenced it! Just be careful not to use WD-40 – that stuff can corrode plastic parts. Also, loose clips on B-pillar trim panels are quite common; I recommend switching to specialized fabric-wrapped clips to prevent rattling over speed bumps. If the noise sounds like metal tearing, you'll need to check the weld points – older cars often develop this issue.
Three Mazda6 sedans in our fleet have all experienced B-pillar rattling issues. Based on our experience, the most cost-effective solution is DIY repair. Simply prepare some foam sealing strips and insert them into the B-pillar gaps - the improvement is immediate. Remember to lift the door frame weatherstrip to reveal the gaps, then use a plastic pry tool for careful insertion. If the noise becomes particularly noticeable when using air conditioning, it's likely caused by thermal expansion-induced metal panel friction - applying panel adhesive to body weld points will solve this. However, loose trim panels along the rear windshield drainage channel can produce similar noises, and this area is often overlooked.
