"General Motors' investigation into our recall of the Chevrolet Tavera, which is built and sold exclusively in India, identified violations of company policy," the company said in a statement. "GM subsequently dismissed several employees."
The company did not identify the employees who mislead Indian officials about their emissions testing, Wall Street Journal reported.
The retired executive, the highest ranking company official implicated by the affair, is Sam Winegarden, the automaker's vice president for global engine engineering, who had worked for GM for 44 years.
India has opened an investigation into the matter, The New York Times reported Saturday.
GM stopped making the Tavera in India this month and said it would recall the vehicle going back to 2005 models to validate that the engines had met emissions standards.
The Journal said GM is recalling 114,000 vehicles in India, in one of the largest ever automobile recalls in the country.
