Nissan X-TRAIL Problems

Good advice but some CVTs are beyond such a fix, as the problems seem to be in the core programming.

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.

From your description the leak sounds quite a severe one, but that means it should be reasonably easy to find. A couple of things you could try would be to drive it through a car wash and watch for water coming in, or you could have a friend hose the car while you sit inside. If you can't see water entering, check the various problem areas after the car has been hosed down to see if the leak has occurred while it has been hosed. It could be a case of trial and error until you can locate the source of the leak. If you think it could be the sunroof start there. You could also check the various seals for damage.

So long as you are still driving the car regularly, and it looks as if you're covering more than 5000km a year, the tyres should be fine down to the tread-wear indicators. They are not sticky high-performance tyres or special soft-compound winter tyres that need special treatment.

The Tucson gets The Tick from me and rates above the X-Trail, but my first choice is the all-new Kia Sportage.

Stop me if you've heard this before. Definitely reconsider as the South Korean brands have made massive improvements in recent years and the Sportage tops the CR-V and X-Trail.

The transmission you've got is a CVT type auto, and I would suggest it's got a problem, possibly the computer that controls it. Take it back and demand they properly assess it.

If there are any warning lights on it could be a problem with the electronics and it’s gone into ‘limp home’ mode. If there are no warning lights on it’s likely to be a fuel issue, and not getting enough fuel to keep it running when under load, which it is when in Drive or Reverse. I would change the fuel filter, check the fuel pressure, and clean the throttle body.

You are not alone, as the mapping in every factory installed GPS is going to be a little outdated — I get emails every week from unhappy owners. The problem is the delay in getting the Australian mapping coded, sent to HQ and then uploaded on to hard drives. The quickest and easiest solution is to use Google maps on your phone. Nissan has previously said it gets the mapping updated as soon as possible.
