I've said it before but I'll say it again, the customer 'service' recieved by Nissan is a joke.  It is horrendous and although I love my Zed I would NEVER buy a Nissan in warranty again as it's a waste of time. 
  
Sorry Nissan but this is a real problem for 90% of the owners and it's putting people off.   
  
SORT IT OUT!
