Executive Summary:
This briefing details a critical safety recall initiated by France concerning specific Citroën C4 III and C4X passenger cars. The recall, identified as Alert number SR/02103/25, addresses a manufacturing defect in the Electronic Braking System (EBS) valve block that poses a significant risk of injuries due to compromised braking and stability control functions. The affected vehicles were produced between May 29, 2024, and June 5, 2024 (C4 III) and May 29, 2024, and June 3, 2024 (C4X). Measures involve a recall of the product from end-users, with an effective date of April 14, 2025. Products with this defect have also been identified in Croatia.
Key Themes and Most Important Ideas/Facts:
1. Product Identification and Scope of Recall:
Product Category: Motor vehicles (Passenger cars).
Brand and Name: CITROEN C4 III and C4X.
EC-type approval/model: e92007/466816*21.
Affected Production Dates:C4 III: May 29, 2024 - June 5, 2024
C4X: May 29, 2024 - June 3, 2024
Company Recall Code: NS9.
Notifying Country: France, with products also found in Croatia.
2. Nature of the Risk and Technical Description of the Defect:
Risk Type: Injuries. This highlights the severity of the potential consequences to vehicle occupants and others.
Risk Description: The core issue stems from a manufacturing flaw in the EBS valve block. "The aluminium of the EBS valve block may not fully cast around the valves."
Cascading Failures due to Defect:Initial Leak: This casting defect "can lead to an internal leak of brake fluid (from one or more of the 12 valve seats)."
Fluid Level Reduction & Stability Control Deactivation: The internal leak results "in a reduction of the fluid level and the deactivation of stability control due to damage to the pressure sensor." This directly impacts vehicle handling and safety.
Contact with PCB & Loss of All Control Functions: Crucially, "The brake fluid could come into contact with the printed circuit board and result in the deactivation of all control functions (including the anti-lock system and electronic brake force distribution)." This represents a catastrophic failure mode, potentially leading to complete loss of essential braking and stability systems.
3. Non-Compliance and Legal Provisions:
Non-Compliance: The product "does not comply with the Regulation on the approval and market surveillance of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles." This indicates a breach of fundamental EU safety regulations for automotive components.
Country of Origin: France.
4. Measures Taken and Implementation Timeline:
Measure Taken: "Recall of the product from end users" by the Manufacturer. This indicates a direct effort to retrieve and rectify the affected vehicles.
Date of Entry into Force: April 14, 2025. This date suggests a lead time for the recall process to officially commence.
Implications:
This recall is critical due to the direct impact on primary safety systems (braking, stability control). The potential for complete deactivation of critical functions like ABS and EBD poses a severe accident risk. The wide range of affected production dates within a short window indicates a specific manufacturing batch or process issue. The identification of affected products in Croatia demonstrates the cross-border reach of this safety concern within the EU market. The effective date of the recall in April 2025 provides manufacturers and authorities with time to prepare for the logistical challenges of retrieving and repairing affected vehicles.
