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??

If it's a DCI, I would say it's the suction control valve. Cost £400 to change on my x-trail.

Hi, did you ever get a resolution to this problem? I'm having similar now - on a 66 plate 1.5dci tekna that I've had since new for 15 months, I've done 42000 miles. Suddenly - mainly going up hill at speed - once you get to 2000 revs it's just losing power in higher gears. It's ok to go to higher revs in 3rd & 4th gear but that's no good uphill on the A38!!! I had this problem once before, going up a hill out if Cheltenham in March 2017 on the A40 but once I got home and left it overnight it was fine, it hasn't shown anything like this again. Until yesterday! I admit I use supermarket fuel, the next tank I'll use one of the diesel performance fuels.

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.

I have a nissan juke 1.6 auto.
it had constant acceleration issues, not holding low mph for short periods.
Nissan had not a clue.
Ive discovered it an i'll fitting PLENUM chamber to the air filter, at low speed , the
engine suck air between the fittin, it possible to silicon seal the PLENUM chamber to
the air filter housing, when cured, remove the air filter housing screw top right, your
sealed air cover filter housing an Plenum chamber will slot into place.

i Have a Nissan Juke 1.6 Auto last year many different acceleration issues, sluggish,
Slow revs kept falling etc. NISSAN SAID DRIVE IN SPORTS MODE ?
THE issue is a poorly fitting PLENUM CHAMBER, it connects off the air filter under the wing.
its possible to seal it to the air filter with Silicon, this will increase the Atmospheric pressure of the air filter along
side Plenum unit...
Also make sure the air hose off the throttle body is securely fitted air tight to the air filter, as the jubilee
clip will not squeeze an seal the hose tight, good luck

OK so I had (as of last week) a 17 plate 1.5dci with 67K on the clock. I used Vpower diesel pretty much exclusively and do loads of motorway mileage. Car hit 62K miles and started with the flat spotting in fourth, fifth and sixth gears between 1500 and 2000 revs when going uphill. Initially going into sport mode helped but still fault occurred just not as noticeably. I found a split pipe by the dpf sensor which was clogged and got it replaced. DPF reading was good (ran emmissions on MOT equipment - yes in the trade). No fault codes on system. Problem went away for a week, then came back. Was always worse after a long distance run. Finally dumped me one morning....RAC came and found EGR fault code (the only time it had thrown a code). No goodwill from Nissan, did try that and not inclined to spend money running through the 119 possible repair protocols in a vain attempt to fix the thing. Shame, liked the car but when you hear possible EGR, Turbo, de-coking of engine and all that can entail (every manufacture has a nightmare with this, often with engine replacements) I cut my loses and sent it off to another land.

I have a brand new 19 plate juke 400 mile on the clock and it is losing power when I am driving. Had it at garage twice can’t find problem, actually said to me sure you not taking foot off execrator and that’s why it is happening. really unhappy told them don’t want car back till it is fixed.
