Tata has offered to replace the starter motor on all old Nano models, but said the move was not related to safety concerns surrounding the world's cheapest car.
The five-seater hatchback, which has suffered a series of fires since its launch in 2009, costs as little as 140 880 rupees (R22 500) for the no-frills model.
A Tata spokesman said the company was offering the replacement starter motors for cars produced between July 2009 and October 2011 because “we have a new one and it further improves the car's performance”.
“There are no safety worries,” he said.
Tata introduced an updated version of the egg-shaped Nano in November to boost customer appeal with a wider range of colours and more luxurious interiors along with better fuel efficiency and engine power.
