Geely Recalls 1,473 Polestar 4 EVs in China over Battery Thermal Runaway Risk

Key Takeaways

• Geely recalls 1,473 Polestar 4 EVs with 86 kWh batteries
• Recall targets vehicles built Nov 2023–May 2024
• Battery internal resistance may rise, causing thermal runaway
• Free battery module replacement; charge only to 70% until fixed
• Earlier Zeekr recall involved 38,277 EVs over same battery issue

Pulse Analysis

China’s EV market, the world’s largest, is under renewed scrutiny after Geely announced a recall of 1,473 Polestar 4 models. The issue stems from inconsistencies in high‑voltage battery component manufacturing that can increase internal resistance, potentially leading to thermal runaway. While the recall size is modest compared with the 38,277‑vehicle Zeekr action earlier this year, it underscores the fragility of battery supply chains and the regulatory pressure to ensure safety. For manufacturers, the cost of free module replacements and the operational logistics of a nationwide recall add a layer of financial strain, especially as profit margins tighten amid intense competition.

The root cause appears linked to a dispute between Geely’s subsidiary Vremt and battery supplier Sunwoda, which previously resulted in a settlement valued at roughly $338 million. Although it remains unclear whether Sunwoda’s cells power the Polestar 4, the broader context suggests that supplier quality control remains a critical bottleneck. Chinese regulators, led by the State Administration for Market Regulation, have been quick to enforce recalls, signaling a tougher oversight regime that could accelerate consolidation among battery makers and push automakers toward more vertically integrated solutions.

For consumers, the recall may erode confidence in premium EV brands, especially as Polestar shifts its sales model to online‑only channels after closing its last direct store in China. The recommendation to cap daily charging at 70% could also affect user experience, prompting buyers to reconsider vehicle choice or demand stricter warranty terms. Industry analysts expect that repeated safety alerts will drive OEMs to prioritize robust battery management systems and diversify their supplier base, a move that could shape the next wave of EV innovation and pricing dynamics in the world’s biggest automotive market.
