Right, well i have owned 2 xtrails, the first a 52 Di and currently a 53 2.5.
Now, they are largely fault free, the facelift version is better built but still has its foibles, and i will start with the in-expensive items!
Front brake calipers seize.
Front brake discs corrode for fun. (luckily inexpensive)
Fuel filler necks corrode out (there is a recall on these check its been done)
The paint is very thin, damages easily, and the front plastic wings scratch easily. Go over any purchase inch by inch.
Alloys corrode if not kept washed regularly.
Diesel timing chains.
HVAC and stereo can play up occasionally.
Avoid models with the built in satnav with the single din stereo below it. Not only is the stereo -really- awful, the satnav isnt much better.
Di's are relatively trouble free but alittle bit of a tractor.
Dci's- very very very very well known for repetitiive turbo failure. There are afew tihngs you can do to prolong the life of the turbo which basically is running on the edge of its envelope. Changing the oil more frequently, ensuring you let it cool off after a run, the Renault ecu update which reduces power, and replacing EGR valves all help but the bottom line is you will have to replace the turbo, EGR valve, & intercooler during ownership.
I work in the motor trade and am involved in tuning / research work so tend to see patterns of failure with various vehicles
For that reason i bought the 2.5 petrol as i like the x-trail generally. It does 30mpg vs 38-40mpg and is almost bulletproof. It's only weakness is it doesnt have the diesels torque, and 1st gear is too high for setting off with any amount of weight on a trailer without burning the clutch. Solo it is very brisk.
Hope this helps??
