Hi Hummer,
Excellent ownership review and follow ups at different intervals.

Enjoyed reading your experience.
I bought XVD 110 PS varient in 2015 August. Just about to complete 4 years with my beauty.
My experience with it has been a mixed bag. It was fun driving it, no problem at all, except of few minor things which I will elaborate, but the worst experience I had was with the Authorised service stations. I live in Gurgaon, and the Authorised Service stations are Not reliable at all. I pity those who leave their cars with them for service.
Anyways, apart from that there were couple of glitches, first, the seat belt used to get stuck everytime I pulled it to fasten. Got that replaced for 1800/- bucks.
Stock media infotainment system started acting weird since Dec last year, it switches ON itself, and sometimes while playing FM it suddenly goes to " Loading CD" mode, looks like it has got brains of its own. Apart from that all is fine, voice quality is superb.
The electronic fault light / diesel preheat warning ( coil symbol) came couple of times while I was driving on highway, I showed it to the service centre every time, but they could not find any error. The car never showed any difference in operation or handling either.
And finally, auth service stations were unable to give it a proper wheel alignment. Everytime they did it, the car would pull to the left. They dismiss the case saying this problem is there with all Indian SUVs, blaming it on Indian roads and rough handling.
But somehow I always got it rectified at my other trustworthy wheel alignment centre from where I got my Continental's cross contact AT as well ( thanks to Tanveer @ tsk1979 for that choice of shoes)
Apart from these few glitches, I never experienced any major issue with the car in these four years of driving pleasure.
I have driven it for 4 years approximately 40,000 KM's, and every time I am in the driver's seat, it is a bliss (Have never experienced the comfort from the passenger seat). Did many long journeys from Delhi to Punjab, Himachal, Leh, Srinagar and it took me everywhere without any hassle. Really reliable when it comes to Engine, Transmission and suspension. Being a front wheel drive I was little apprehensive about taking it to Leh via Manali route, but the ground clearance helped me go through the rough patches easily.
Driving in the city took some time getting used to, since it was my first diesel car, and the gear change from 1st to 2nd and downshift from 3rd to 2nd had to be done quite early. Got used to it in few days. Even the pick up is good once you touch 1500 rpm, pretty good for a diesel engine.
I have no plans to sell my car any time soon. Having found my way around, I take my car to a local garage for service and install Original Nissan/Renault parts procured online or through the service centre. No more frustrating time spent at service centres and it is way cheaper as well.
Planning to change my infotainment system too.

and along with it might get a steering wheel mount controls as well. If anyone has any experience using it, please advise.
I am thinking of putting on some nice leather seats, but the work Hummer has done on his car seats is hard to find. (You got it done on the doors as well, that was superb)
So, in the end I would say I am a happy Nissan Customer even though the service centres tired their best to spoil it for me.
