Going to Authorized service center is Annoying sometimes by leaving the car ; asking help from other's for a drop off ;appointment bargaining .I have only one point to add there is an option of mobile service from Nissan ,they will come to your place and do the needful.Major services are excluded.It's the same price / safe / warranty will be intact/comparatively cheap and reasonable.Forget about it if your car is not belongs to that brand.
