Nissan admits problems with telematics, is manufacturing a new part to replace defective units

Tue Apr 24, 2018 1:40 pm

I had a royal fight with my Nissan dealership. This is the third time (or fourth? losing track...) bringing the car in for the same issue where the TCU drains the 12v battery and I refused to come get my car until they did something about it.

They finally conceded to have a Nissan engineer look at it when he visited, and today they called me to let e know that they were finally admitting that the TCU had a problem. They said as long as I didn't use the Carwings (NissanConnect) app, it wouldn't cause the drain (I don't believe that) They said that they would be replacing my unit when the new part arrives. Software upgrade is not an option. It sounded like Nissan is actually manufacturing a new different part. No timeline on when that will actually happen.

The general issue with all these telematics solutions are that they wake up the car to request information. If the polling is too frequent the car stays powered up and drains the 12v. Or the car takes a long time to go back to 'sleep' (a low power draw state.)

So letting (or forcing) the car to sleep and not waking it up until a drive is in fact a solution, albeit with loss of telematics.

You might be able to stop nagging the car only from the phone App side of things, but you will have to actually CLOSE the app. Don't let it operate in the background.

The few times I have had issues happened when I did not get plug in reminder and/or charge complete emails and texts. Therefore, just avoiding the use of the App may not prevent the issue unless you also disable ALL notifications (something I am not willing to do so I tolerate an occaisional fuse pull/DTC clear session). I rarely use the EV Connect App to check status or start climate control, but it is nice to have when I do want to use it..

Sadly I think we were told the same thing last year about Nissan having engineers look at this and acknowledging a problem. Sounded like they were going to get a fix out relatively soon.... We still wait. This is absolutely horrible response from Nissan. They have damage customers vehicles and have provided no recourse. As far as I am concerned customers should be able to demand reimbursement for batteries replaced while this issue persists. Once it turns into a cash drain for Nissan then they will spring into action. Until then we are going to keep getting the run around from clueless dealers who look at you with suspicion and mocking when you tell them of this issue. They will not acknowledge it.

So I think we are getting the standard run around response. Once you push back hard enough they will give you the "we know about it and are working on it". We should be able to say then put it in writing, I will put a new battery in here at the dealer and guess who is going to keep replacing that battery until Nissan fixes this? LOL Wishful thinking I know. I am holding off on the TCU upgrade. Which at this rate means I probably will never do it because Nissan will drop support for the cars before they ever fix the TCU.
