Text: Understand the car di original Li Dezhe
[understand the car di original industry] On September 30, the China Consumer Quality Safety Promotion Association held the "2021 China In-use Car Corrosion Research Report Phased Research Results Sharing Session". The phased research results of the "Corrosion Research Report on In-use Vehicles in China" released at this meeting focus on components and models with high attention from the three dimensions of consumer corrosion investigation and analysis, key component corrosion analysis, and overall level of corrosion resistance. Perform an in-depth interpretation.
The issue of automobile corrosion is receiving increasing attention
It is understood that the recall information published by the Defective Product Management Center of the State Administration for Market Regulation shows that the number of recalls caused by corrosion has reached 134, involving more than 7.81 million vehicles, 54 brands and more than 100 models are estimated based on the current inventory, which means that about 1 out of 37 cars will be recalled due to corrosion problems.
Industry insiders also pointed out that the current automotive corrosion warranty at home and abroad is also quite different. Automotive products sold in Europe, the United States and other countries generally provide consumers with an open corrosion resistance warranty, while automotive products sold in China are very different. Provide consumers with less corrosion-resistant quality assurance commitments. In this market environment, automobiles entering the Chinese market may reduce their investment in anti-corrosion products, while automobiles exported to foreign countries will increase their corresponding investment in anti-corrosion products. In the long run, China has the potential risk of becoming a low-lying area of anti-corrosion quality.
Comparison of vehicle corrosion performance between 3 years of service and 6 years of service
According to the results of this specific research and analysis, during the 3 years of service, Yinglang, Yidong, Haval H6 , etc. 4 There were no parts corroded in the exterior area of the vehicle body, and the performance was relatively excellent; 3 models such as Corolla and Yinglang did not corrode in the passenger compartment area, and the performance was relatively excellent; Yinglang, Tiggo 3 , Lang Yi_ 8 models including span18span did not corrode in the luggage compartment area.The performance is relatively excellent; the two models of Lavida and Corolla have no parts corroded in the engine compartment area, and their performance is relatively excellent; the three models of Lavida, Yinglang and Corolla have the lowest corrosion rate of parts in the chassis area, and their performance is relatively excellent.
Overall research level of corrosion resistance
When the vehicle's service time reaches 6 years, , Sylphy, Yinglang, Haval H6 and other four models have no corrosion in the exterior area of the vehicle body, and their performance is relatively Excellent; Corolla, Yinglang and other three models have the lowest corrosion rate of components in the passenger compartment area, and their performance is relatively excellent; Haval H6, Lavida, Yinglang and other four models have no corrosion in the luggage compartment area, and their performance is relatively excellent; Lavida, Yinglang The corrosion rate of parts in the engine compartment area of the three Corolla models was the lowest, and the performance was relatively excellent; the three models of Yinglang, Lavida, and Corolla had the lowest corrosion rate of the parts in the chassis area, and the performance was relatively excellent.
