Hi there. Many of us are having the same problem. There is nothing wrong with your 12V battery. My 5 y/o battery still holds a charge just fine, even if I replaced it thinking it was bad. The new 3G TCU gets locked 'on' downloading certain data. It remains active until the 12V is dead. There...

Hi. After disabling all regular updates, not sharing data, declining data transfer, etc from within the car, the TCU lock up goes away. Even in that state you can still use the remote climate control feature. I've done this for >6 months without a drained battery or other issues. In that state...

Hi. I guess I'll post the same thing every couple of months for those catching up. The issue is with the TCU getting stuck in a loop calling the Carwings backend system. The solution is simple, yet Draconian: decline all data sharing inside your car, disable all charging station updates, etc...

I just want to say that I've been waiting for this for years. I have a 2013 with the annoying beeps and this LeafSpry Pro update has cured it. I drove last night and this morning with the windows down just so I could hear.... nothing :D Thank you andrik, Turbo3 and anyone else deserving...

Hi. I drive the car every day with relatively short distances Mon-Fri and longer on weekends. This has been the pattern for >2 years now. A solar panel that can supply ~12V/100mA (1.2W) will likely be enough to counter the TCU bleeding issue. If I remember correctly, I measured the drain on...

Hi, That's right, it's very broken. When I said "workaround" I meant to avoid my 12V being drained dead. As far as I know, Nissan has no solution for what it's clearly a widespread issue with the newly upgraded 3G TCUs. I read somewhere in this forum that Nissan engineers had confirmed the...

Cursing was used, tears were shed, blood was spilled, nightmares ensued, heads went bald, marriages were broken... then someone pulled up the schematics and followed the lines to the 3G radio. For me it came when I figured something was up with the radio because my 12V battery would die the...

Hi. Speaking for myself: there's no fix from Nissan. I had to disable all forms of telematics connections in the car to stop my 12V battery from draining dead. I've had about 6 of these dead 12v battery incidents since the "upgrade" in Feb. Apart from the aggravation of a dead battery just as...

Hi all, I sometimes hear wind noise coming through the window. I roll (only) the driver's window down halfway through and close it again in one continuous move. Sometimes it takes 2 or 3 times to make a full seal but it eventually does and the wind noise goes away. One way to see if the leak...

Hello dudleypippin, try this: take the 12V battery out of your car and charge it with a LA battery charger for at least 12 hours. If you can give it a full 24hr charge, even better. If you can run the charging cycle twice over those 24 hours, that would be best. The point is to fully charge and...

Hello Tal and thank you. I've been thinking that all of these issues started after the 3G modem upgrade. I had no issues at all with the 2G modem and everything worked with it. With my limited information on the issue, I see two possible causes: 1) The 3G modem hangs because it tries...

Hello. I feather both the accelerator and brake pedals with OCD-like presence of mind. I do that to the angst of some ICE behind me that start peaking acceleration after 30 MPH or so while I'm still accelerating evenly. It isn't a good day unless I'm >6 miles/kWh. But this is not about that...

Hello LeftieBiker. I did not say "nanny state tactics". That implies government/political mandates. I said that applying the brakes for me is "more nanny stuff". The "other" in the "other nanny stuff" also include not letting me use the navigation screens while the vehicle is moving. There are...

Hi all and thanks for the quick comments. Oh brother, more nanny stuff. What's strange - and good - is that this is not how our 2016 Chevy Equinox behaves: I don't have high hopes that this "feature" can be defeated but I'd love to disable that for sure. The same people that don't allow me or...

Hi all, I have noticed this issue a few times before but last night was the clearest instance yet. You drive at ~50 MPH and firmly but briefly (~0.5 seconds) fully apply the brakes. Immediately let off the brakes and you'll notice the car will hold the brakes for you for another 1 or 2 seconds...

Hi all, Update to my previous post. I charged the 12V battery to 13.5V overnight, installed it this morning, drove a few miles, no issues. A few minutes ago, I hit the 'refresh' button on the Carwings webpage and it loaded the EV battery percent charged. This had not happened in over a week...

Hi all, I understand there's a different thread on this topic but that one's already way too long. About 2 weeks ago, I woke up to a dead car. I "jumped" it for a few mins and it worked fine for the day. A few days later, same thing. Again, jump and go. Starting this Saturday, the darn car has...

Hi all, Another possibility: it's the Carwings radio that remain on and retrying to connect to Nissan. I've had my battery drained down twice and both times Carwings was also having issues. Right now, neither the app or website can connect to the car. Maybe it's all coincidence. JR

Hello all, As with pricdx01's case, I can send charge/climate control commands but do not receive that status back. Even when the car is charging, the status for plugged-in and charging is not updated. All else works - some of the time - like updating driving records, receiving navigation...

Hi, Sorry to be so vague but I can't recall exactly what I did to make mine work. Try different zoom levels and/or change view options in map. Mine didn't show for the first year or so but I did something with the menu that made it show up. JR
