NHTSA Complaint #11631149 — 2016 AUDI S6

Subject: Formal Complaint Regarding Defective Arnott Front Air Strut To Whom It May Concern, I am writing to formally report a significant safety concern regarding a defective Arnott FL front air strut purchased via RockAuto for my 2016 Audi S6 (VIN: [XXX] ). The air strut failed within five days of professional installation. This failure compromised the safety and functionality of my vehicle's suspension system, potentially risking further damage and endangering passengers. I was forced to drive the vehicle briefly in this compromised state to arrange for reinstallation, creating an additional safety hazard. Details of the issue: Product: Arnott FL Front Air Strut (purchased via RockAuto). Professional Installation Dates: October 25, 2024, and reinstallation due to failure on November 27, 2024. Failure Description: The air strut lost functionality within five days of installation, causing a significant drop in vehicle height and inability to maintain proper suspension. This defect demonstrates a failure of Arnott’s quality control and has left me concerned about the safety of their products, particularly when they play a critical role in vehicle performance and passenger safety. I am requesting that NHTSA investigate this matter to ensure no systemic issues with Arnott's products compromise the safety of other drivers. I have attached supporting documentation, including invoices for installation, reinstallation, and further details on the defective part. Thank you for your attention to this urgent safety matter. I look forward to your acknowledgment and any updates regarding this investigation. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
