Subaru Admits Employees Manipulated Fuel Economy Data


In December of last year, Subaru and Japanese law firm Ohno & Tsunematsu opened an internal investigation to determine if employees tampered with fuel economy ratings for some of its Japanese-market vehicles. The issue arose in the wake of Nissan and Subaru being faulted for decades of improper final inspection procedures at specific plants. While the issue initially seemed relatively benign, subsequent interviews with Subaru employees resulted in confessions that “certain data with respect to fuel economy and emissions may have been altered” during the course of final vehicle inspections.

What originally appeared to be automotive employees taking bureaucratic shortcuts evolved into something a bit more serious. Subaru recently released the results of the investigation and has admitted to falsifying the fuel consumption data of 903 cars assembled at its Gunma Manufacturing Division and Yajima factory. However, the internal probe only encompasses December 2012 until November 2017. All data from before this period is mysteriously absent.

Interesting, considering the suspect employees claim the figure flubbing probably started around 2002. 

A final report on the matter has been submitted to Japan’s Ministry of Land, Infrastructure and Transport. We’re expecting more to come of this, as the ministry was upset about uncertified workers signing off on vehicles even before news of the falsified data surfaced.

Subaru attributes the altering of fuel consumption data to senior employees advising inspectors to change results for each vehicle that did not meet internal quality control standards. It also said “managers at or above the section chief level and executive managers were not aware of alterations.”

According to the automaker’s official report, employees also altered the data with the intention of minimizing variance in measurement values in order to avoid questions from the group chiefs and section chief. As a result, some of the vehicle data was altered to show it performing worse.

The investigation looked into roughly 6,500 vehicles, discovering that data was inappropriately altered on 903 of them.

At face value, it looks like inspectors were just trying to avoid making more work for themselves and the company. But that would also be a perfect excuse for a more sinister, decade-long corporate plot to bolster fuel economy data. There’s no evidence to suggest this, but questions remain as to why senior to junior inspectors decided to implement a policy they had to know was against the rules.

Subaru’s been extremely apologetic since the final inspection issue came to light in 2017. In the translated report, the company apologizes numerous times and said it will take every step necessary to restore lost trust:

“Subaru takes [this matter] very seriously and profoundly regrets that this issue was taking place in addition to the Nonconforming Final Inspections disclosed last year … these problems undermined the trust of its customers and other stakeholders in our final vehicle inspections, product performance data and catalog values released by the company, and thus in Subaru itself.

The problem stems from causes similar to those behind the Nonconforming Final Inspections, namely a lack of awareness of public interest in, and importance of, final vehicle inspection work, a lack of normative consciousness leading to inspection results being altered to their own advantage, and inadequate internal communication … Subaru needs to reform its corporate culture from the ground up.

Subaru sincerely regrets the facts uncovered by the Investigation and has openly disclosed the details. In addition to taking measures to prevent recurrence of the Nonconforming Final Inspections, Subaru is determined to implement measures to prevent recurrence of this problem, to reform outdated aspects of its corporate culture such as authoritarianism, reliance on precedents, and formalism, and to become a genuine ‘upright company,’ [with each employee thinking], ‘what is the right thing?’ and implementing [it correctly].

Subaru’s management and employees will work collectively to restore lost trust and ensure that such circumstances do not recur.

We would like to reiterate our deepest apologies for the significant trouble and inconvenience caused to our customers, partners, and all other stakeholders.”
