Tata Motors on Monday said it would replace the starter motor free of cost in over 1.40 lakh of Nanos, but at the same time denied that it was a recall.

The company said it is changing the old starter motor with a new and better one and added that the exercise is expected to cost about Rs.110 crore to the company. The whole activity is estimated to be the biggest ever in the Indian automobile industry.

“We have devised a better starter motor and so we are upgrading it in our old Nanos for improved performance. We have not received any complaint for this and this is not a recall,” said a Tata Motors spokesperson.

The company started its exercise in October and has already replaced the starter motor in about 50,000 Nano units, he added.

When asked about the total numbers of cars that will be covered under the replacement activity, the spokesperson said: “We will change the parts in all the old Nanos that were sold before launching the Nano 2012 in November.”

As per Sources, Tata Motors has sold 1,40,428 Nano units till November, 2011, since the car’s launch in 2009.
