If you think, your Nissan has a serious defect that affects the safety of the vehicle, report it to the Nissan Dealer immediately. If you’re not happy with how the Nissan Dealer is dealing with your report, in the UK you should contact the Driver and Vehicle Standards Agency (DVSA).
But before that, you can describe the fault of your Nissan in our forum. Maybe some other Nissan owner will learn that he experienced the same issue. Multiple occurrences of identical defects mean a better chance of success in a complaint filed with the DVSA. Our website is visited by Nissan owners from all over the world.
