The firm beat on earnings and revenue for the three month period despite a 40-day strike by 48,000 workers, which only ended last Friday, October 25 - the longest strike at the company since 1970.
It saw 34 plants closed across the USA and disrupted the car maker's operations in Canada and Mexico.
In the three months to end September, the firm posted adjusted earnings of US$1.72 per share, compared to the US$1.31 Wall Street analysts had expected. That was on revenue of US$35.47 billion, compared to a consensus figure of US$33.82 billion.
Only two weeks of the United Auto Workers’ (UAW) strike occurred in the quarter in question but still reportedly dented GM's net profit of US$2.35 billion in the three months by US$1 billion.
Most of the impact will strike the fourth quarter and the firm said the employee action will end up costing it $2.86 billion in net income for the whole year.
Due to this, GM cut its guidance for full-year earnings to US$4.50 per share from US$4.80 per share, compared to the between US$6.50 and US$7 per share it stated previously.
Despite this, in early New York trading, GM accelerated 5% higher to US$38.54.
