(Yicai Global) April 24 -- Dongfeng Nissan Passenger Vehicle, Nissan's joint venture in China, has upgraded its refund policy in response to the recent Mercedes-Benz scandal.

New Dongfeng Nissan car buyers can replace their vehicles within seven days if facing issues with the engine or gearbox, or perhaps with the electric car battery, motor or control system, the Guangzhou-based JV said in a statement today. 

The policy shift is sparked by an online video that circulated earlier this month, involving a woman who bought a brand new Mercedes-Benz that started to leak oil before she left the dealership, run by Xi'an Lizhixing Automobile Service, that did not allow her to change the vehicle. 

Carmakers may complement China's consumer law with these kinds of guarantees. If a consumer notices that their car has quality problems in the main parts of the engine or gearbox, they can choose to replace these parts for free within 60 days after the purchase or within 3,000 kilometers of mileage, according to the Chinese law.
