Nissan Juke power loss randomly under load

[wacattack]

My wife's juke has developed a weird issue which Nissan are failing to diagnose. When accelerating the car randomly loses power when accelerating. I'd describe it as beyond a flat spot as all drive just disappears, although the engine doesn't stall, it just lacks drive.

This happens usually at random and has occurred at various rev ranges. However I am able to recreate the issue with +90% success rate if I drive at a steady speed at about 2100rpm for 10 seconds or so then press rage throttle to accelerate. Instantly the power drops despite having my fut down on the throttle. Eventually the power will come through after a couple of seconds or so but until then the power and speed drops, despite trying to accelerate.

They've changed the fuel primer and the fuel filter at a cost of £400 so far. Their latest proposal is the fuel pump and have quoted a further £1500.

Has anyone got any suggestions??

Unfortunately not. For us it's worse in the winter. I don't know if it's the cold or wet that causes it.

It also typically only happens for us if you are driving at a steady speed then put your foot down to accelerate. If you press the clutch before accelerating it doesn't typically do it.

I've just put a full tank of premium fuel in to see if that makes a difference.

I'm getting rid of ours very soon as nissan couldn't diagnose it.

Did you ‘ever’ find the problem? Same with wifes car and we cannot get a proper diagnosis or fix. I cannot keep forking out for checks/ works and it not be resolved.

thank you

Unfortunately not. I gave up on it and got rid of it.

Running premium fuel definitely helped, but nissan themselves couldn't diagnose it. They wanted me to part with the best part of £2k as the next option and they still couldn't guarantee it would fix it. Terrible service.
