Volkswagen and its Audi and Seat subsidiaries are recalling nearly three million vehicles worldwide, including at least 950,000 in Germany, due to a corroding steering rack mounting bolt that can fracture and lead to a total loss of steering control under high-stress maneuvers.
The Defective Fastener and How Steering Control Fails
At the center of a massive multi-brand recall sits a humble component carrying part number N 105 524 02—a hex-flange bolt measuring M12 by 1.5 by 70 millimeters. This fastener secures the rack-and-pinion steering housing to the front subframe across millions of compact cars and crossovers produced over a span of more than a decade. While manufactured to strict factory specifications, the bolt is vulnerable to environmental degradation.
Over years of driving on treated roads, moisture enters the mounting area and mixes with road salt and oxygen. This accelerates corrosion, reducing the effective cross-section of the fastener until it can no longer withstand mechanical loads. When the component gives way, the steering rack remains attached at a secondary mounting point, but continued stress can fracture the aluminum housing itself. In the worst-case scenario, drivers face a complete loss of steering capability during high-load low-speed events like parallel parking or sharp three-point turns.
Engineers and safety regulators note that the defect provides almost no reliable warning signs before a failure occurs. While some drivers might experience unusual metallic rattling, front-axle knocking, or slightly altered steering play, the degradation happens silently beneath the vehicle over years of service.

Affected Models, Production Windows, and Global Reach
The recall spans three distinct automotive nameplates within the wider group, touching millions of owners across Europe and North America. According to data released by the Federal Motor Transport Authority, German registrations account for at least 950,000 of the total affected vehicles, while global figures approach three million units.
| Brand | Affected Models | Production Window |
|---|---|---|
| Volkswagen | Golf, Golf Variant, Tiguan, Touran, Caddy, Atlas | September 24, 2013 – July 1, 2024 |
| Audi | Q3 | October 31, 2017 – May 23, 2024 |
| Seat | Ateca, Tarraco | April 2016 – September 2024 |
The campaign involves reference numbers 17016R for Volkswagen, 17014R for Audi, and 17017R for Seat. While Seat models account for tens of thousands of units in the German domestic market alone, the bulk of the global recall volume is concentrated in core Volkswagen passenger cars and the Audi Q3 crossover.
The Two-Year Investigation Trail and Repair Bottlenecks
Volkswagen received its first field report involving a corroded bolt and broken housing outside North America in October 2024.
However, the sheer scale of the service campaign has triggered logistical friction. Because millions of vehicles require attention simultaneously, authorized service networks face temporary shortages of the newly engineered coated bolts.
Due to the currently still limited availability of the new, more corrosion-resistant bolt, a new bolt of the previous type can initially be used in some of the vehicles. According
This component shortage means that some vehicle owners may need to visit a service center twice. Under the interim procedure, dealerships will install a fresh fastener of the original specification as a purely precautionary measure, requiring a second appointment later to receive the permanent polymer-coated upgrade.
Industry-Wide Cost Pressures and Supply Chain Realities
Analysts estimate that replacing a steering fastener across four million vehicles—factoring in an estimated one-hour labor window alongside logistics and materials—will impose a multi-hundred-million-euro burden on the automaker.
Industry commentators point out that the choice of a fastener with minimal corrosion protection reflects decades of intense cost-cutting strategies across the automotive sector. To protect profit margins on shared-platform architectures, manufacturers have historically squeezed suppliers on minor components, a dynamic that executives are now re-evaluating as competitive pressures from Chinese automakers mount and quality failures translate into expensive recall campaigns.
Next Steps for Affected Vehicle Owners
Automotive clubs and regulatory bodies advise owners of matching model years to monitor official communications. While manufacturers have not issued a strict do-not-drive order—indicating that engineers believe the vast majority of fasteners retain sufficient structural integrity—drivers are urged to schedule a workshop check promptly.
European owners can verify their status via brand hotlines or national transport registries, keeping in mind that vehicles with outdated registration addresses or imported models may require owners to initiate contact with dealerships directly.
