The power batteries of new energy vehicles (NEVs) sold to households in the initial years are gradually nearing their warranty limits, typically set at 8 years or 120,000 kilometers. This has led to a significant influx of early-model NEVs transitioning into a warranty-free period, where issues such as battery failure repairs, diminished driving range, and safety concerns have emerged as prominent challenges in the NEV after-sales market. Experts highlight that during the rapid growth phase of the NEV industry, the market predominantly concentrated on new vehicle sales, enhancing driving range, and advancing intelligent features, while largely neglecting the maintenance and repair needs of existing vehicles. Now, with the onset of the 'warranty expiration surge,' these issues are increasingly coming to light. The industry is undergoing a transformation, shifting from a competitive landscape centered on new vehicle sales to a crucial test of after-sales services for the existing fleet.
