燃油车份额萎缩后再添质量隐忧，J.D. Power调研指其长期质量持续滑坡

Core Viewpoint - The long-term quality of fuel vehicles is declining, which challenges their previously established reliability advantage against electric vehicles [2][4]. Group 1: Quality Issues - J.D. Power's report categorizes quality issues into two main types: malfunction-related problems and design defects. Fuel vehicles have seen a continuous increase in long-term quality issues, with a 9% overall increase in PP100 (problems per 100 vehicles) over three years [2][5]. - Design defect issues have increased by 20%, accounting for 45% of complaints, indicating a significant deterioration in fuel vehicle quality [2][4]. - The top 10 reliability issues for fuel vehicles are primarily concentrated in the areas of smart technology and NVH (Noise, Vibration, and Harshness), contributing over 75% of the increase in complaints [3][4]. Group 2: Brand Comparison - Despite improvements in technology and quality among domestic brands, there remains a significant gap in quality compared to international and luxury brands. Domestic brands' design-related issues have increased from 84 PP100 in 2023 to 102 PP100 in 2025 [4][5]. - Luxury brands also show an increase in design-related issues, rising from 66 PP100 to 84 PP100 over the same period [5]. Group 3: Market Trends - The market share of fuel vehicles has been declining, with sales in 2024 dropping to 11.99 million units, a 17.3% year-on-year decrease, and further declining to 49.9% market share in the first nine months of 2025 [5][6]. - The decline in market share has led to a series of reactions from automakers, including production cuts and urgent adaptations to compete with electric vehicles [6]. - Despite a slight recovery in sales in September 2025, the quality issues, particularly in smart technology, remain a significant concern for fuel vehicles [6][7].
