The findings come from an internal investigation ordered by the Japanese Ministry of Transport, after incorrect test were detected on Subaru and Nissan cars, Jornal de Negocios reports.

In the case of Suzuki, 6,401 of the 12,819 vehicles tested since 2012 had manipulated test results. Mazda has 72 of 1,875 vehicles with manipulated test results since 2014 and Yamaha has identified seven cases in 335 since 2016.

"Regarding emissions inspections ... it is true that there have been improper actions. We sincerely apologize," said a Yamaha spokeswoman quoted by CNBC.

Suzuki chairman Toshihiro Suzuki apologized to a press conference. "It is significant that so many of our products have been improperly processed and we take this very seriously. We are sorry," he said.

A Mazda manager ensured that there were no deliberate changes to the data and that the incorrect tests did not affect the quality of the vehicles. "The company takes the incident very seriously and will ensure that such incidents do not recur," he said.

Mazda assured through a statement sent to Business that "no alteration or falsification of improper test data was recorded in any of the [test methods JC081 and WLTC2]" and states that "test data containing speed detection errors were found in 72 cases, out of a total of 1,472 vehicles tested under the JC08 method. Two reasons for these errors were identified. First, the system was not created to automatically invalidate the results when a speed detection error occurs. Secondly, the test procedures leave the determination of the speed of error detection at the expense of each inspector individually. "

The brand notes that "all test data have been re-examined and the results show that they had no effect on the specification of fuel consumption and emission figures, which were not found in WLTC tests."

The Japanese manufacturer "accepts that there were errors in a small number of tests but the situation was identified quickly and measures were taken to prevent this from happening again in the future."

Shares of Yamaha fell 4.63%, while those of Mazda lost 1.30% and Suzuki shares fell 6.04%, the biggest drop since late 2016.

In July, Nissan admitted mistakes in measuring fuel consumption and pollutant emissions in 19 models of vehicles sold in Japan.
