umm, ok. now we have established that we are getting a warning on the dash.

so we are either fixing software or the car. as i understand it, the OP drove the car without issues. so it maybe a software thing. (which is VERY easy to believe) over a hardware thing which i would think Nissan techs at the dealer would have probably discovered on their own

Latest from the dealer:

"The field engineers have ordered a new TCU for your vehicle for tomorrow morning. They found a hard failure with that unit that they believe is disrupting the CAN-BUS communication line between other systems."

What is a TCU?

Telematics Communication Unit

Luckily it's right under the glovebox, so it's easy to get to! :D

Good news that it's something that can be fixed pretty fast...even better news is that parts are available in under 24 hours...I doubt it has to come from Japan.

I wouldn't be so sure. I've tracked my Apple computer from Shanghi, China to my front door in 24 hours. If something like this is on a high-priority for Nissan, the part would be on the next flight out of Oppama to the US. That flight would only be...what...9-10 hours? That's the duration of a Tokoyo-LA flight. :geek:

ok, so its not the car , its part of the support structure of the car. the owner could have continued to drive it without issues until Carwings was fixed...kinda sounds like my issue.

They COULD just take a part out of another LEAF sitting at the Port of LA.

Just got a call from the dealer regarding my Leaf. I talked to the technician for awhile and he explained everything to me. The first night they disconnected the 12v battery (since you couldn't completely turn the car off and it would have drained the battery). After reconnecting, the problem could not be reproduced.
But, the TCU was still reporting a "hard fault" and the meter assembly also was reporting some error code. These have been replaced on my car and they are taking them back for further testing. But, my car is back in business. Yeah! And, if it happens to anyone else I think they'll know exactly where to look now.
Overall, I am extremely happy with how this was handled. They clearly are intent on keeping us happy and quickly taking care of any issue.

Not looking forward to stopping by the gas station to fill up my loaner. :lol:
