Renault 5 & R4 E-Tech Recall: 19 EVs Affected by Battery Fault

Renault is launching a preventive recall affecting 19 electric vehicles in France: 13 Renault 5 E-Tech and 6 Renault 4 E-Tech, all produced between December 12, 2025 and January 28, 2026. The fault concerns a potential detachment of the anode within a cell of the 52 kWh battery, detected by internal quality control before any customer incidents.

"Given that the battery represents about 40% of an electric vehicle's price, this is a major intervention" — According to industry experts

A Production Defect Localized on the Anode

The problem identified by Renault concerns a potential detachment of the anode within a cell of the battery pack, which occurred during production at supplier AESC. This anomaly can cause several malfunctions depending on the severity level.

In the least severe case, owners may observe a degradation in range or a charging block with the "battery charge impossible" message on the dashboard. The most concerning scenario involves a risk of thermal runaway potentially leading to a fire, although this situation remains rare for this type of defect.

The Renault 5 E-Tech and Renault 4 E-Tech share exactly the same technical specifications and the same battery, explaining why both models are affected by the same recall.

How Many Vehicles Are Affected?

In France, only 19 vehicles are affected by this recall: 13 Renault 5 and 6 Renault 4. At the European level, the total number rises to 65 units produced within the critical window.

According to Renault Germany, only 4 vehicles were affected across the Rhine, already recalled to workshops even before the official notification from authorities. This very limited proportion demonstrates the effectiveness of the manufacturer's quality control system.

A Complete Replacement Covered by Warranty

The repair procedure consists of the complete replacement of the high-voltage battery, an operation requiring approximately 5 hours of downtime. If the vehicle needs to be transferred to an authorized center, Renault provides a loaner vehicle.

This intervention represents a considerable cost for the manufacturer, as the battery constitutes about 40% of the value of an electric vehicle. The operation, however, remains entirely free for owners, in accordance with warranty obligations.

Affected customers have been contacted by postal mail. It is also possible to check a vehicle's eligibility via the dedicated Renault website by entering the VIN chassis number.

What is the Exact Cause of the Defect?

According to the European Commission database, "a production anomaly in the supplier's factory can cause delamination of the anode in a battery cell, where the electrode material detaches and can damage the current collector and the separator."

This technical failure can potentially lead to an internal short circuit in the traction battery. The phenomenon, while impressive, remains circumstantial and linked to a specific production batch.

Renault assembles the ready-to-install battery packs internally via its Ampere division, but sources the cells from AESC. This organization allows for a two-tier quality control.

Impact on the Market and Competition

This situation does not significantly affect the commercial momentum of the two models. The Renault 5 E-Tech maintains its 2.9% market share in France, while the R4 E-Tech is gradually finding its audience with 1,642 units sold.

Direct competitors like the Hyundai Inster or the upcoming Citroën ë-C3 are watching this situation closely, which remains marginal in its scale.

The electric Nissan Micra, developed on the same AmpR Small platform and in production since January 2026, does not appear to be affected at this stage according to European authorities.
