This clutch problem needs to be corrected and if done correctly should never return.

I purchased the Nissan NP200. After 2 months I returned the vehicle and advised the dealer that the clutch was shuddering. They took it for a drive ,on returning they said they found nothing wrong with the vehicle. I then returned for its 1st service at 8879 km and was told they have to replace the clutch plate. After this service the vehicle was fine for a while till approximately 1350km when it stated to shudder again. I returned the vehicle for its second service at 16128km and told them about the shudder. The manager then drove the vehicle and on return told the lady that was dealing with me , the shudder was with in spec and I should continue driving it as is. I feel this is unacceptable I have had 3 other modules of Nissan and never had a problem
