Because of its quality, Kumho Tire was well-known in Chinese countries last year and the company was almost plunged into a disaster. With painstaking thoughts and hopes for recovery and revitalization, there is no alternative but to begin with quality. The chairman of Kumho Tire Co., Ltd., Lee Han-hoon, recently disclosed to Kumho Tire's tires from the management to the system of quality, and from the service to the goal of innovation.
It is reported that since April 2011, Kumho Tire has carried out services including the implementation of recalls and free testing in the face of the market and consumers. By the end of December 2011, over a period of 8 and a half months, Kumho had more than 2,500 national A dealer and designated 4S shop, received and tested approximately 850,000 vehicles, and recalled and tested a total of approximately 410,000 tires for free replacement.
In order to better serve consumers, since January 1, 2012, Kumho Tire has continued to implement the "customer first" service concept, and the recall work has become daily work. The 400 customer service hotline established during the recall will continue in a fixed mode. The product guarantee policy and 5-year warranty period will continue to be implemented.
At the same time, Kumho Tire's five major commitments to the community have also been fulfilled: Self-inspection, rectification and improvement within the company have been completed, and the re-examination of production processes at 4 factories in China has been initiated. The 24-hour video surveillance is started in the important production areas of the factory, and objective monitoring by third parties is welcome. Kumho Tire also develops and strengthens the training of workers' professional skills and professional ethics, improves employee welfare, and enhances employees' sense of belonging and pride. At the same time, Kumho Tire also actively participates in public welfare undertakings and organizes active participation of employees.
In addition, Kumho Tire also conducted a more robust construction of its quality assurance policy in 2012: Announced that the VIP protection policy and promotion time will be extended again, and that the products sold will still enjoy Kumho Tire Safety Policy and related promotional offers; The service period of the package has been extended from 3 years to 5 years. This is both a reflection of Kumho’s confidence in its own products and a highly responsible performance for consumers.
At the same time, in order to face the market competition, Kumho Tire also actively upgraded its product technology R&D and production while upgrading its service system. In 2012, Kumho further increased its R&D efforts and launched two new products tailored specifically for Chinese consumers. ECSTA KU39 ultra-high-performance luxury sports tires, driving speeds up to 300 kilometers, to ensure maximum stability at high speed; CITY VENTURE KL33 urban comfortable off-road tires, through the continuous side-by-side pattern design, maximize tire comfort.
Li Hanxi said that in 2012 Kumho Tire will be more committed to enhancing consumer confidence in products and perfecting service mechanisms in the sales and circulation process. With a positive attitude and sincere attitude, Kumho Tires will accept criticism and suggestions from all sectors of the community with moderation. With this as a benchmark, we will continue to improve and manage our own product quality and service guarantee system, continuously improve after-sales service measures, and face the market and consumers with a brand new attitude.
