GAC doubles Aion battery warranty to 300,000 km
GAC Aion will cover some CALB battery packs for 300,000 km or eight years after Aion S owners reported failures beyond 150,000 km.

GAC Aion has doubled its battery warranty for electric vehicles equipped with 177 Ah lithium iron phosphate (LFP) batteries, extending coverage to 300,000 km or eight years. The company says it will replace defective battery packs free of charge.
The policy applies to CALB-made batteries installed in some Aion S vehicles. According to GAC Aion, problems began appearing in cars that had traveled more than 150,000 km. The automaker acknowledged the cases, apologized to customers and promised to strengthen remote battery monitoring.
If the monitoring system detects abnormalities, owners will be invited to official service centers for a free inspection. When a defect is confirmed, GAC Aion will cover the repair or install an entirely new battery pack. All work will be handled through the company’s official network across China.
Battery reliability becomes a competitive issue
The incident highlights how quickly failures in a specific component can affect an electric-vehicle brand. For some Aion owners, the previous 150,000-km threshold proved insufficient, with vehicles beginning to malfunction around that mileage.
LFP batteries are generally associated with strong service life, so early failures can damage customer confidence disproportionately. In China’s competitive EV market, buyers compare not only driving range but also long-term reliability. Because the Aion S is one of GAC Aion’s mass-market models, the issue carries more weight than a problem affecting an experimental vehicle.

The new process—remote monitoring, diagnosis and replacement without disputes—is intended to contain the problem. If failures remain limited to part of the Aion S fleet, the impact may stay localized. Continued complaints, however, could turn the expanded warranty from a customer-relations measure into a significant cost for GAC Aion.
