Speaking over it, Chaba said, "I am on vacation in US right now. I will be going back to China to my office on August 5th."

A General Motors spokesperson had earlier said in an e-mailed statement, "General Motors' investigation into our recall of the Chevrolet Tavera, which is built and sold exclusively in India, identified violations of company policy. GM subsequently dismissed several employees."

The spokesperson did not disclose on who all have been asked to leave saying "we are not providing further comment on personnel matters" and said further queries be directed to his Indian counterpart.

"We do not comment on internal personnel matters," GM India spokesperson said. Without going into details, the statement said: "We take these matters very seriously and hold our leaders and employees to high standards. When those standards are not met, we will take the appropriate action to hold employees accountable."

Last week, GM India had announced that it was recalling the Chevrolet Tavera BS3 (2.5L variant) and BS4 (2.0L variant) from model years 2005-2013 to address emissions and specification issues. It had stopped production and sale of the Tavera BSIII on June 4 and the Tavera BSIV on July 2.

Last month, the firm had announced it was temporarily suspending production of Tavera and the diesel variants of both the hatchback and sedan versions of Sail model, citing quality control issues.

GMI is still investigating in the case of the Sail model to ascertain how many units have been affected. The company had said it will resume production of the diesel variants of Sail hatchback and sedan by the end of this month, while that of Tavera BS III by the end of August.
