Response to Customer (End User) Inquiries

A customer service desk has been established within DENSO in order to respond quickly and appropriately to comments and suggestions from customers. While strictly adhering to secure management of personal information, these complaints, comments, and questions, as well as any responses made, are promptly fed back to the relevant departments. In this way, DENSO works to improve services and operations.
For issues of quality and warranty of OEM products (which are branded by our business partners) supplied to automakers, DENSO asks that automakers’ dealers and service centers provide advice and respond to customer inquiries.

Specific activity

1. Establishment of a global service network

To ensure that its customers receive high-quality and seamless service worldwide, DENSO has established a service network of global sales companies. At the same time, we constantly monitor and evaluate quality in the market and promptly provide feedback regarding market needs and information to the relevant departments. This feedback is reflected in our product development and improvements to services and operations.

In Japan, our designated service station system, which was launched in 1954, currently consists of a network of 716 DENSO service stations (designated service stations and dealerships) belonging to DENSO Sales Japan Corporation.

Overseas, we have established core bases in Europe, North America, Asia/Oceania, and China. In addition, we have a total of 4,054 DENSO service stations that are operated by 29 overseas sales companies.

PIT & GO Automotive Service Station (overseas)

Overseas, growing automobile demand in Asia, Africa, and other emerging markets is generating greater needs for vehicle repair, maintenance, and other after-sales services for not only new vehicles but also used ones. To improve customer satisfaction for customers with aging vehicles, we have been establishing authorized shops under the brand name “PIT & GO”* that provide quality and speedy service.
As of March 2017, we operate 16 shops in Cambodia, Myanmar, Indonesia, Thailand, Malaysia, Laos, and Singapore.

【TOPICS】

Sixth Nationwide Service Skills CompetitionServicing Skills Competition   (April 2017)

We held a national competition in which 21 employees selected from our service stations across Japan participated. These employees showcased their technical skills, competing in the three categories of battery charging systems, common rails, and customer service. Not only did this competition help to maintain and improve the capabilities of our service station staff, it also motivated them to pursue self-improvement through interaction with other service station engineers.

We aim to enhance the 3Rs of water when selecting equipment to use. This means minimizing water consumption (Reduce), using spent water again (Reuse), and treating and re-circulating water (Recycle).

Charge System Competition: Masanori Harada (Aihou Denki Co., Ltd.)

The Servicing Skills Competition is an extremely positive stimulus, providing an opportunity to improve service skills and increase motivation. At the nationwide competition, my perspective was broadened through conversations with the other participants gathered from around Japan. As a variety of new technologies are introduced in the future, I look forward to supporting ongoing service skills improvements to provide services that customers find extremely satisfying.

Common Rail Competition: Makoto Murota (Nakagawa Denki Inc.)

The Servicing Skills Competition provided me with valuable experiences unattainable in my everyday work. As automotive technologies become increasingly complex, I want to be able to provide solid support and services that continue to satisfy customers through information and training on new technologies provided by DENSO.

Customer Support Competition: Tomohiro Miura (Osanai Battery Co. Ltd.)

As the nationwide competition approached, the expectations and pressure became intense and there were times when my confidence wavered, but I was extremely encouraged to receive assistance and support from many people. When my name was called as the winner, I was overwhelmed with an incredible sense of joy and accomplishment. More than anything, I was pleased with this assessment of my daily work efforts and filled with confidence.

Future Initiatives

In order to continue to accurately meet the expectations of customers and earn their trust, the DENSO Group and DENSO service stations will continue to work as one team to create products and provide after-sales service that can satisfy customers.
