The first turbo on my X-Trail developed the "whistle" in November 2006 when the car had done around 30,000 miles, and was replaced under warranty in December 2006.
Last week, the car started to lose power and pump out black smoke; I limped to my local Nissan dealer and have been told that the replacement turbo has now blown too!
An associate at work has had exactly the same problem with the turbo on his car going, and there is clearly a problem either with the design or quality of manufacture of these units.
I will hopefully have my turbo replaced under warranty (the car is only 3 years old in March 2008), but this is clearly unacceptable and Nissan should be protecting its reputation for quality, reliability and customer service by replacing failing units swiftly and without demur.
Good car otherwise, with good pulling power for horse boxes and the like, and nippy acceleration when called for (and when the turbo is working)!
I was about to purchase another, but the turbo failures are disturbing from a manufacturer that prides itself on reliability, and I am having second thoughts.
Not only the X trail, but the Primera 2.2 suffers the same fate.
I'm on my 3rd turbo, the longest having lasted 16000 miles.
My Nissan X-Trail turbo failed last year. Had it replaced. Now the intercooler has failed. Have been told it will cost about £300 to have it replaced. It sounds like a common fault. It's about time Nissan did a recall on the turbo system.
