Re: 2018 Leaf 2.0 "Service EV System. Unable to restart after power off"

Thu Apr 04, 2019 10:34 pm

Nissan finally called after having the car for five days and said a bad cell triggered the error message. Strange since three weeks prior to the break down, during recall inspection plus maintenance, the diagnostics showed the batteries SOH (assuming it means State Of Health) at 100%.

They said it would take no more then three weeks for whatever repairs, bringing the car back to us before Japan's Golden Week and my plan for a 1,100km (684mi) road trip. I was sort of hoping that repairs would over run into the holiday so I can get Nissan to swap the 2017 Leaf with something more suited for these road trips. It's back to figuring out logistics for charging along the way.

I'm not sure what the dealership is calling the "SOH" but it's rare for even a new Leaf to read 100% SOH on LeafSpy. I suspect that it's something more akin to their worthless "Battery Health Report" with its fine granularity of one to five asterisks...

Just had that happen to me.
2018 SV with 8k miles, built in March, bought in June
Got "Service EV system unable to restart" message. So I did the usual checks of 12V battery and all that but got nowhere.
Leaf Spy pulled two DTCs:
P31E7 000B Restart inhibition EVC-310
P0AA6 1A08 Hybrid battery sys isolation fault EVC-157

Had it towed in, dealer just called to tell me it's a bad cell in the pack and it'll be at least a week of fixing.
Driving gas loaner meanwhile :(

If you folks haven't yet, please add these reports to the '2018 Leaf defects' topic. Now I'm getting worried about mine, although I don't know that I ever drive fast up a hill with less than 50% SOC...

This is either the tip of the iceberg of just within the expected defects that slip past quality control.

Anecdata but my failure is with 7,000km at Tokyo speeds. Mostly putting around under 60kph on rolling hills. Have taken road trips at highway “speeds”; gone up long uphill grades at speed; and managed to take it down to 6% charge left. I am a bit of a lead foot but still manage to not touch the brake pedal using ePedal.

Has been at the dealer almost at three months intervals for non-repair inspections. I know they’ve pulled usage data as they comment how the car is driven. Hmmm... curious. They did tell my wife that short trips are bad for the battery but didn’t explain in what ways.

The first 30kwh packs had a fairly high cell failure rate. I don't know if the cell manufacturing process is just glitchy at first with new cells, or if packing them in so tightly is causing problems.

Taking a peek through the Nissan EV, I could see my car is now charging at the specialist repair facility. I take it this as a signal that whatever repair has been completed.

* It's now day 11. (Car is charging)
* Nissan consumer facing seems to take a day off Tuesday, day 10, and the car was responding but idle.
* On day 9, car was offline during the day and but by the evening back online.

So I'm guessing that it took a day to make whatever repairs.

Cars back. Nineteen days on the loaner. No further apology or any further explanation on what went wrong.

Got mine back. Took 22 days, of these three or four of actual work and rest waiting for parts. Here is the writeup (also had them replace chattering wiper blades). 11 hours of labor for battery cell. Oh and apparently each module is a cool $500+
