Nissan X-TRAIL Engine Problems

I'd question their diagnosis of the engine coating burning off; I think it could be deeper than that.

The vibration could be coming from a variety of sources on the engine and in the transmission.

The dealer is doing the correct thing in getting the car in for a proper investigation that will hopefully reveal the cause of the problems.

At this stage, as the car is new you should co-operate with the dealer while they are trying to resolve the issues, but at the same time maintain a watching brief to make sure there is a genuine attempt to fix your car.

The fan only comes on when the temperature reaches a certain point under normal running, but always runs when the AC is turned on. It could be the thermostat sticking, but I would be getting a mechanic to pressure test the system first.

The CVT oil should be changed every 100,000km. As for the fuel consumption it's best to do a check yourself by measuring how much fuel it is actually using. Judging the consumption by how far the gauge falls is very inaccurate, and I wouldn't stake my life on the fuel consumption gauges in the car. Do an actual measurement and you will know exactly what the consumption is. Nissan claims an average of 9.1L/100km, 7.7L/100km on country driving, and 11.5L/100km on city use. I would expect your car would fall somewhere between 9.1 and 11.5L/100km.

I doubt that it’s the battery or starter that’s causing your problem. I would suggest digging deeper into the engine itself, perhaps even check for a leaking head gasket.

It’s possible water has got into something in the engine bay when you were cleaning it, and I doubt it would come good just by driving it. Get it to a dealer or mechanic to have it checked.

It could be any number of things I’m afraid. It’s clearly not the battery. If it doesn’t turn over when you turn the ignition key to start it could be a faulty starter motor; if it does crank, but doesn’t fire look at the ignition system.

Yes, you can, providing of course it’s the petrol engine and not the diesel.

I don’t believe that what you want is out there, and can only reiterate past advice, buy a Patrol/Pajero/Prado/LandCruiser.

If it has made by a reputable spare parts manufacturer, then yes, it probably is ok, but I would be looking to replace the leaking seals rather than the whole cover assembly.

There’s not much between them, but the Honda is regarded as being a little better than the Nissan overall. It’s well-equipped, good value, and practical. Another to consider is the Mazda CX-5.
