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

Thu Aug 30, 2018 10:27 pm

Hi All! First post here... I did search but couldn't find anyone with the same issue.

My UK 2018 Leaf 2.0 Launch Edition is less than 6 months old, with under 6,000miles on the clock. Last week it failed to select Drive or Reverse with the error "Service EV System. Unable to restart after power off".

After getting her back to the dealer, we finally picked it back up two days ago. They admitted they hadn't seen the issue before and that it showed a "Rapid charger failure" diagnostic code. They couldn't confirm 100% that it was fixed but were "confident".

This morning, same thing happened. As anyone else had this? If so, and joy in proper diagnostics from a Dealer and a fix?

I have not seen that on my 2018 Leaf. However, it sounds like it may be an issue with the vehicle immobilizer system. Below is what I see in the manual on this system:

=================================
NISSAN VEHICLE IMMOBILIZER SYSTEM

The NISSAN Vehicle Immobilizer System will not allow the power switch to be placed in the READY to drive position without the
use of the registered key.

If the power switch fails to place the vehicle into the READY to drive position using the registered key, it may be due to interference
caused by another registered key, an automated toll road device or automated payment device on the key ring. Restart the
EV system using the following procedure:

1. Leave the power switch in the ON position for approximately 5 seconds.
2. Place the power switch in the OFF position and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device (which may have caused the interference) separate from the registered key.

If this procedure allows the power switch to be placed in the READY to drive mode, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.

My 2018 leaf (1200 miles) had the exact same failure symptoms 2 days ago. The dealer does not understand the problem. The failure happened after a Colorado snow storm. I had to shovel out the car. The technician may have detected a battery cell failure. Did you learn any more? I will report back with anything I learn

I had the same error message in mid-September with just over 500 miles on 2018 Nissan Leaf. i had to get the car towed to the dealer and drive a loaner for three weeks while the problem was fixed. Fortunately, the entire repair was under warranty and cost me nothing except for the inconvenience. As it was explained to me, the dealership had to remove the lithium-ion battery and take apart, test to find the problem and replace a couple of faulty modules. The repair took longer than expected, I was told, because initially some of the wrong parts arrived. The receipt shows installation of dam-rubber battery case, seal-battery, breather-battery case (quantity 2), betaseal 57302N and betaseal 43533 (2 of each), and battery sub assy - main. If not under warranty, the cost to me would have been $1354 for parts and $1165 for labor. I don't really understand the technical aspects of this, but the car seems to be working fine now.

Dealership called and said I also have bad battery cells.

I find this thread very interesting...and glad it got a few responses.
I don't know how many 2.0 Leafs have been sold, but it's safe to say it's a lot less than the 1.0 version...and I can't remember this many reports of "bad cells" in the first year or so of Leaf 1.0. Plus it doesn't seem isolated to any one region (or country).

My neighbor bought a new 2018 about 3 months ago - against my recommendation - and it is now at the dealer with the same symptom and diagnosis: two bad cells.
59,991 miles/12 bars/289 Gids/68.54 AHr/101% SOH/101.64% Hx 7May15 w/ new Lizard (barely made the warranty).
71,770 miles/12 bars/256 Gids/59.04 AHr/88% SOH/87.92% Hx 3Mar16 at lease return.

Now driving a 2016 Volt Premier.

Seems to be more common than expected, as this happened to me this morning as well.

I did a search on the same error msg and found this post https://www.mynissanleaf.com/viewtopic.php?t=26155
prior to your post.

I just hope it doesn't take weeks to fix. If so, they better give me a damn good loaner for the inconvenience, especially if I have to start paying for gas again.
