From the date of Purchase, the car is smoking like hell during traffic & idling. The Car is drinking too much of Engine Oil. In 26,800 kms the car has consumed about 37 Litres of Engine Oil. The company has opened the complete engine, replaced the cylinder head but of no use. The staff at the Cargo Motors Workshop cleans up everything, service the car then make a test run for 3-400 kms at my expense & certify that every thing is ok. This has been going on since the date of purchase. I have visited personally the customer meets, Tata office in Ahmedabad, written letters to Tata Motors-Pune/Mumbai but of no use. They are dragging the matter till the warranty expires.
