Mitsubishi Admits to Cheating in Fuel Economy Tests Since 1991
Mitsubishi says the tampering dates back to 1991 and is still unclear about the extent of damage done.
Mitsubishi Motors, the Japanese automaker that acknowledged last week that it had intentionally lied about fuel economy data for some of its models, said an internal investigation found such tampering dated back to 1991.
President Tetsuro Aikawa told reporters that the probe was ongoing, suggesting that more irregularities might be found.
Aikawa added that a lot was still unknown and it’s uncertain what action the company will take. He said he didn’t know why employees resorted to such tactics to make mileage look better.
We don’t know the whole picture and we are in the process of trying to determine that. I feel a great responsibility.Tetsuro Aikawa, President, Mitsubishi
Tokyo-based Mitsubishi Motors had repeatedly promised to come clean after a massive scandal 15 years ago involving a systematic cover-up of auto defects.
The inaccurate mileage tests involved 1.57 lakh of its eK wagon and eK Space light passenger cars, and 4.68 lakh Dayz and Dayz Roox vehicles produced for Nissan Motors.
The models are all the so-called minicars with tiny engines whose main attraction is generally great mileage. They were produced from March 2013 and the problem surfaced after Nissan pointed out inconsistencies in data.
The automaker found the company’s mileage goal for the minicars that had been set in 2011 was suddenly raised in 2013. Why that happened is unclear, according to officials.
Aikawa also said it was unclear how customers were going to be compensated because the extent of the cheating was still under investigation.
Mileage fraud is a violation of Japan’s fuel efficiency law for autos because buyers are eligible for tax breaks if a vehicle model delivers good mileage. Possible penalties are still unclear due to the uncertainties over the investigation’s outcome, according to the transport ministry.
Mitsubishi Motors released two diagrams explaining how road tests were manipulated.
The company, which also makes the Outlander sport-utility vehicle and the i-MiEV electric car, has arranged for a panel of three lawyers, including a former prosecutor, to further investigate the mileage scandal from an outsider’s point of view, with a report expected within three months.
Production and sales of all affected models have been halted.
Mitsubishi Motors struggled for years to win back consumer trust after an auto defects scandal in the early 2000s over cover-ups of problems such as failing brakes, faulty clutches and fuel tanks prone to falling off dating back to the 1970s. That resulted in more than a million vehicles being recalled retroactively.
