Something is up with the Nissan Carwings data network, a way for the all-electric Leaf to communicate with smartphones and the mothership back in Japan. Carwings is how drivers can remotely charge their vehicles and heat or cool the cabin. What the current problem is is not fully understood, but Nissan is admitting there's an issue. On its Leaf Facebook page, Nissan Social wrote:

Nissan LEAF Owners:

We are aware of an issue with connectivity between the remote functions between your CARWINGS smartphone app and your LEAF. Please be assured that we've been working around the clock to address this issue and are closing in on a fix ASAP. We sincerely apologize for any inconvenience this causes you.

We agree, that's not all that helpful. Over on the MyNissanLeaf forum, you can find plenty of reports from Leaf drivers all over. Users have not yet been able to figure out a fix (by resetting their phones or parts of the car, for example). Even worse, the outage has apparently been going on for about a week now and, as AutoblogGreen reader Michael W put it, "As someone who works in IT, and has 6 servers I manage, I would be on my way to the unemployment line pretty darn quick if I'd let an unresolved issue plague a mission critical server for 7 days!"

We've asked Nissan for more information about what is known about the problem but have not yet heard back.

*UPDATE: Nissan says, "We have generated sample service requests and have traced them through the network so that we can analyze the behaviors to identify failure points." More to come.

*LATER UPDATE: Nissan now says "Our teams performed some code updates, and the Nissan LEAF CARWINGS service is running as normal with no recurring issues in the last 14 hours. We will continue to monitor service performance and work to improve service stability."

        Warmed up now. Decided to utilize the in-car climate control timer instead of sending the command remotely (which still isn't working, BTW).

      It's not the car it's who they hired to do the back end. In addition this is a pathetic topic. Use the Google and write about something interesting. Year after year and posts about nonsense. People that care about this can just read about it on the LEAF forums. It's NOT news it's filler. I know people send you really good tips but those require less copy and paste skills. Provide less content and some quality.

        Rare for me to defend autobloggreen, but savor the moment, Sebastian and company! ABG has cleaned up their act and has been posting less crud lately for sure. Remember all the Pike research articles and PR fluff pieces that seemed to dominate 2010-2011? Give 'em a break. This might not be a big story, but it is still news, dude.

          Well, let's not be too hasty. Yeah, things aren't as bad as the repeated planted "leak" stories for the same vehicles over and over like we saw in 2010 and 2011. But on the other hand, the Ford C-Max goes into a rough patch (over mpg) and suddenly ABG posts 2 positive articles about it engineered by Ford right in the middle of the maelstrom. I'm not trying to trash ABG, they have done better. But they're still doing press arm duties. I agree with the posting of this story in particular though.

        I keep up with the FIsker and Tesla forums, but admit that I don't frequent the Leaf forums. This is news to me. ABG should report on this, or rather, write a quick blog post that links to the real article. (Lighten up, Francis)

        @noev: "It's not the car it's who they hired to do the back end. " Based on the total lock-up of the system, what makes you think Nissan didn't write their own back end here?

      This is why i hate these electronic/computerized gadgets in cars. Everything is proprietary and they come from a company that specializes in making mechanical things, not electrical things. You are locked in to their system that only they know how to work. The people who programmed the system are likely contractors or don't work full time. As a former IT guy, i do agree with the quote from the IT guy entirely. 7 days of something not working is awful. I manage the entire backend of an online school and am expected to have a fix for any major disaster within an hour because my boss is on the edge of a serious emotional meltdown in about 2 minutes. 7 days of not fixing a problem and i'd be fired. I know the car can be operated without this 'carwings' thing, but that's still not acceptable. This is a $35,000 car from a major company. come on now.

        If i told my boss that i'd got some information on the problem ( and that's all i'd done ) for a week, i'd definitely be fired. And i work for a company that makes about $1M/yr. They should have had a clue within a few days. Your Indian helpdesk idea might be a 1:1 picture of what's going on behind the scenes, lol

          The best part about Indian helpdesk is when they pretend they're actually onshore... "Really? Your name is 'Michael' and you're in Cleveland? How's the weather out there?"

        "Nissan says, "We have generated sample service requests and have traced them through the network so that we can analyze the behaviors to identify failure points."" See? They're working on it. Actually, it means Nissan hasn't the slightest clue why it's not working. Tho apparently, someone in IT called Nissan's Indian helpdesk, and followed the instructions to shut down and restart all the of the machines. LOL.

      Oh, boy, more news from Nissan's Twits: "UPDATE: We'd like to take this opportunity to share the status of the CARWINGS connectivity issue we shared with our LEAF owners yesterday afternoon. A cross-company team has worked throughout the night and has been able to identify a problem which has contributed to latency and error conditions our owners are experiencing. Tuning changes and a code correction have reduced but not eliminated failures. Our team continues to investigate and we will provide updates via this thread as they develop. Thank you for your all your comments and feedback! – Nissan Social + Nissan Vehicle Connected Services" So, presumably, at least part of the population is now working just fine. Or so they'd have us believe. Dun-dun-DUN!

      So basically, people have to start & stop manually, versus automated? This can't be automated by the EVSE / "wall charger"? Thermostat, water softener, washing machine, lawn watering, etc. all have these kinds of controls to set and forget locally.

        Oddly, EVSEs never seem to contain their own timers. I don't know why. As far as I know, this doesn't affect LEAF charge timer operation, it just means you can't start and stop charging remotely via your smartphone. Or even monitor it.

          Really? My Blink has a timer. My LEAF has a timer and it works fine. Dudes. The problem is with CARWINGS not the car or the EVSE. We are talking telematics, the brave new world of motoring that the big car companies are clearly struggling with.

          Exactly. I don't know why the EVSE Charger or OBC can't be pre-programmed - this isn't complex stuff, very basic function to include.

        This has nothing to do with an EVSE. It's a software bug. Because it is on ABG it is now some kind of news as if the wheels were falling off. Nissan RUSHED the LEAF to the market and patched together the systems, that is a FACT, not an opinion. Clarion head unit, POS. Navigation, POS. No heat pumps, rush job. That is well known. However a software bug is not news. But on the internet and ABG everything including a SUV hybrid that can eek out one more MPG is worthy of a post. Blah, Blah, Blah.

          @noev: No kidding, it's a software bug. Same as if it caused the throttle to stick open like a Toyota Camry. Or refuse to unlock the charger plug like a Tesla #ModelStranded. In this case, people have to manually start / stop and can't pre-warm their cars in the winter. #FirstWorldProblems.
