NEW DELHI: Maruti Suzuki will recall more than 77,000 cars, most of which the Baleno hatchback, to upgrade an airbag software and fix other problems, taking the number of vehicles that auto makers in India recalled so far this month to about 1.5 lakh.The nation’s largest car maker will upgrade the software that controls the operation of airbag in 75,419 Baleno cars manufactured between August 3, 2015 and May 17, 2016. While these cars are both petrol- and diesel-powered, 15,995 diesel variants from this lot will be inspected for possible replacement of a faulty fuel filter as well. As many as 17,231 units of the recalled Balenos were sold abroad.A press release from the company didn’t say if there were any accidents or other problems. In a statement to ET , Maruti said the Baleno recall has no connection with the Takata brand of airbag inflators, which were involved in the recall of millions of vehicles worldwide by various auto makers. It didn’t disclose any financial impact.This is the biggest single model recall by Maruti. Previously the company had recalled more than 55,000 units of the Dzire , the popular entry-level sedan that features in the current round of recall as well.The auto maker said it will replace a faulty fuel filter in 1,961 units of the DZire with automatic transmission this time. All these are diesel variants. Earlier this month, Maruti recalled around 20,000 units of the S-Cross crossover to fix faulty brake parts. That was followed by US-based auto maker Ford’s announcement last week recalling nearly 49,000 EcoSport compact SUVs.According to industry body Society of Indian Automobile Manufacturers , auto makers in India have recalled about 2 million vehicles since the local auto industry adopted a voluntary code of vehicle recall in July 2012. Analysts see this as maturing of the local industry.“Globally recalls are becoming a norm. Over 60 million vehicles were recalled in 2015,” said Abdul Majeed, partner at Price Waterhouse, a network firm of PricewaterhouseCoopers in India.“In India, there are no guidelines for recall but the good thing is OEMs are doing this proactively. With new products coming in, supply chain is becoming more complex and auto makers have to keep inspecting to address such glitches,” he added.In April, the Baleno was eighth on the list of top selling cars in India, with sales of 9,562. DZire’s sales on the other hand have been falling consistently, and for the first time in many years the model lost its place among the top selling four cars based on monthly sales in April. Last month, Maruti sold 10,083 units of the DZire, compared with 16,490 a year earlier.Starting May 31, Maruti said, owners of the affected vehicles will be contacted by Maruti dealers.
