Got an ex Demonstrator Navara in August. Same month an issue occurred with Ad Blue light coming up on the dashboard. It has been being repaired for the last 7 weeks with the HQ engineers being unable to establish the cause of the issue. During this period I have been driving Nissan Micra until the manager of the local dealership took over the case and informed me that I can contact Nissan and request like for like replacement. I did raise a complaint case as instructed however Nissan cannot provide me Navara with a hard top and so I have been driving a mini van without windows which freaks out my dogs plus there is only space for 2 passengers squashed, in addition the comfort of driving is very poor. I have also been informed that I cannot be reimbursed almost £1,000 to cover for 2 finance instalments which I paid for a broken car sitting in a local dealership as Nissan HQ does not provide financial compensation. What’s more, there have been ongoing discussions between the local dealership manager (who has been very helpful) and the HQ and the issue around the HQ engineers not being able to pin point the root cause. Nissan HQ have been adamant to approve order of new parts or replace my vehicle without knowing what the root cause is. It seems that they might have a solution now however the parts are coming from Japan so again more delay. I would like to emphasize that it is Nissan HQ who have been unable to pin point the root cause and it is Nissan HQ who released vehicles on a market without appropriate Quality Assurance tests – it turns out that the Ad Blue issue occurs quite often since it has been released aiming to minimise emission levels. As a customer I have been forced to wait for 7+ weeks without my car, I have lost £1,000 so far, I have clearly established that a warranty does NOT mean anything except from waiting and losing money. Nissan HQ are also far from supporting vehicle replacements when clearly it is their solution design and/or manufacturing fault and a lack of sufficient testing – all resulting in releasing vehicles on a market without a knowledge of how to repair them in case something goes wrong.
