Don't Buy Nissan Cars...bad quality.

Think before you decide to purchase any Nissan Car in India. Their products are not upto expectation and the quality of the cars are worst. Even after sale service and responses including Nissan customer care is pathetic. Why I am saying all the above is because most of the customers who bought the Nissan cars are facing the same.
I purchased Nissan Terrano after looking at different model cars/SUVs just because I was impressed with the outside looks of Terrano and the brand name of Nissan.
The vehicle was not gone through minimum quality check because in the new vehicle the auto lock was not working which was later rectified during the first service. I was happy that it was a small issue. But later too many issues started and I was surprised is it happening only with my car or it is for others too. I started enquiring with others who purchased Nissan Car and I was shocked to hear that almost all of them are facing the quality issues with their cars. After 6 months of my purchase, there started some annoying noise from the engine. When I brought it to the service advisor notice, charged me around Rs. 2500/- to clean the injectors in the engine. But still the noise didn't come down. After 1 year of the purchased, the gear shift started to stuck. Again when brought to the notice of service advisor, they accepted there was an issue with the gears and changed them under warranty. Within an year, there are lot of noise coming from Doors, roof etc. When informed to the service person, their statement is "Nissan is not BMW or Audi, such noise will come from the Nissan cars". Now the major issue is, within 1 and half year, I noticed rust on all the doors and other parts of the car body. Even Nano cars are manufactured with better quality and some 10 years old cars will not have rust formation but 1 or 2 years old Nissan cars are having this issue. Hope we can understand what is the quality of the cars they are selling in India and cheating the customer by creating outer looks for the car just to attract the customer and increase the sale. I discussed with the service centre regarding the rust and they said they will take it up with Nissan India. It is more than 5 months after informing them about the rust formation but still they didn't get back to me on the solution. Weekly I am calling the CRM of the service centre, for 4 to 5 times they said we are following it up with Nissan India but now they stopped answering my calls.
Can someone suggest if we can file a case in Consumer court against NISSAN. I have all the evidence written in the job card when I gave the vehicle for services. Very bad service from Nissan.

After posting all the above details in FB, mailing to Customer Care, their customer care is least bother to contact and provide any resolution.
