Nissan Cube 2011 Emitting Black Smoke with Performance Issues: Seeking Guidance

Hey! Sounds like you might be right with your suspicions. Something similar had happened to my 2014 Nissan Juke a while back. The engine light was on, it stalled a few times, and the smell you mentioned, oh boy, it was there. Did some quick research online and then took it straight to the garage. Turns out my beast had incorrect software values for the fuel pump. Apparently, the software wasn't communicating with the pump correctly, causing it to behave erratically. Was a bit tricky for the mechanics to identify and confirm at first, but once they did, they reprogrammed the software, updated it to the correct values. Post the garage visit, the stalling and black smoke issues were sorted one hundred percent, and the gas consumption went back to normal too. So, while it seemed like a serious issue, it was essentially an electronic problem messing with the fuel system. Not a mechanical failure, thank God! My heartfelt advice? Get your Cube to a knowledgeable, trustworthy mechanic ASAP to get the software checked and updated if necessary. Good luck with it!

Hey there! Sounds like quite the technical issue you're having with your Cube. I'm no expert but what said about the software causing trouble really resonates. I've got a 2011 Nissan Rogue which had virtually the same symptoms as yours and the garage diagnosed it as a miscommunication issue between the vehicle's software and the fuel pump. I'm curious,, by the way, do you recall approxily how much you ended up shelling out to get your Juke's software reprogrammed and updated? Also, has your ride been smooth sailing ever since or have you noticed any other glitches that popped up post-fix? Thanks in advance!

Hey there! Well, to answer your question, the software issue with my Juke was completely sorted once the mechanic reprogrammed it. This tweak cost me a pretty reasonable 45 Euro. A decent price to pay for getting the car back on track, if you ask me. And yep, it's been smooth sailing ever since. All those symptoms vanished - no more black smoke, stalling, or increased gas guzzling, and the strong exhaust odour got the boot too. So, it was definitely the incorrect software messing up the low pressure fuel system. Since getting it fixed, my Juke's been purring like a kitten. No issues whatsoever. Hope this info helps. And good luck getting your Cube back in shape!

Cheers, you guys. It's such a relief to hear that someone else has had an identical issue and got it sorted! Honestly, I was worrying that it might turn into an expensive engine issue or something. Your advice,, is duly noted - I'll definitely get the car to a reputable mechanic and have them check out the software. I'll keep your suggestion in mind too and inquire about the potential of it being a software miscommunication with the fuel pump. Now that I've got some clues, I'm feeling more confident about my garage visit. Your responses have been incredibly helpful and I really appreciate it. I'll be sure to update you both with how it turns out. Have a good one, lads!
