Mitsubishi Will Be Adding Eight More Vehicles to MPG Misreporting Scandal

Mitsubishi Motors was ordered Tuesday by the Japanese transport ministry to stop domestic sales of eight more vehicle models due to cheating on fuel economy reporting, according to a Fortune report.

Investigation into fuel economy on models including the Pajero, Outlander, and RVR SUVs were lower than stated in marketing catalogs, the ministry reported. That brings the total up to 12 affected models, including four mini-vehicle models reported in April.

“Our investigation confirmed that the fuel economy on eight models … were as much as 8.8 percent and on average 4.2 percent lower than advertised,” the ministry said in a statement.

The Japanese transport ministry ordered Mitsubishi to stop selling those eight models while it determines correct mileage reporting, a process the ministry expected would take a few weeks.

In April, Mitsubishi admitted that it had falsified fuel economy ratings on two of its mini-vehicle models, along with two similar models produced for Nissan Motor Co. Mitsubishi reported that none of these misreported vehicles affected cars sold in the U.S.

The Mitsubishi Outlander is sold in the U.S., but the investigation findings will need to be released before the full impact on markets outside Japan is known.

The Japanese automaker has been struggling to recover after admitting the misreporting in April. Sales were suspended for nearly three months. Mitsubishi reported last month that the resulting slump in domestic sales led to a 75 percent plunge in quarterly operating profit. A plunge in market value prompted Mitsubishi to seek financial support from Nissan, which agreed to buy a controlling one-third stake for $2.2 billion.

An internal investigation found that Mitsubishi had been guilty of poor corporate communications, slack governance, and pressuring engineers to perform with limited resources. Mitsubishi has admitted to using unapproved methods to calculate vehicle mileage for 25 years.
