check the cat converter for failure and blocking the exhaust system

Is it a petrol or a diesel?

Check front brake pads for wear and possible replacement. If never changed originals, there is a high likelihood they are worn out.

I have a 2009 Nissan X-Trail QR25 2.5 litre petrol engine and CVT transmission with 65,000 km on the clock. Ever since new it has an intermittent power loss on acceleration from a stand still you have to pump the accelerator pedal to get the power bad. I have complained to Nissan during warranty and out, they have been unable to find a fault. Nissan Australia now dismisses the situation as it's out of Warranty. I have even written to Nissan Japan without them being concerned. The day that one of my familiar is seriously hurt because this fault they might then walk up to them selves that there is a real series health and safety issue.

Has any else had this problem?

check the check valve to the break booster. sounds like a low vacuum problem.

do a google search for the part or try Ebay

Probably stereo itself.

I think you may have a problem with your electric assisted power steering motor. Is the loss in power only when your are making sharp turns to the right or left?
Do you hear any load noises or squeling sounds?
You should have it inspected, Don't want you to lose control while driving.

On 1999 9-3 models there is a fuel filter located under the pass rear door. However if this was plugged it would not kick back in after a short time. Typical suspects are crankshaft position sensor which will work well on a cold engine and intermittently cut off and on when the engine is hot. Its a cheap sensor, and very easy to change. Possibly check condition of spark plugs and the DI cassette as well. Also check function of Fuel pressure regulator. Any fault codes stored (CEL on?)
