NONCOMPLIANCE INFORMATION REPORT
1. Manufacturer:
Nissan North America, Inc., Smyrna plant
2. Vehicles Potentially Involved:
The production period of affected vehicles involved is shown in the table below.
Model Dates of Manufacture
MY 2018 – 2023 Nissan LEAF September 29, 2017 through January 27, 2023
The noncompliance (as described in Section 5 below) is specific to Nissan LEAF vehicles
listed above. The issue present on these vehicles is related to the defroster operating
instructions in the owner’s manual and their effect on the Positive Temperature Coefficient
(PTC) heater under certain conditions. The Nissan LEAF is the only model equipped with a
PTC heater as the primary heating device.
Model Year 2011-2012 Nissan LEAF vehicles are equipped with a different PTC heater design
that is not affected by the subject condition and therefore excluded from the recall
population.
Per NHTSA’s request, Model Year 2013-2017 Nissan LEAF vehicles have been removed from
this recall population and are subject to a separate Noncompliance Information Report
being filed in conjunction with this amendment.
The name, description and part number of the subject component is below:
A~~licable Model Part Name Part Number
MY2018 LEAF Owner’s Manual l MY 2018 LEAF Owner’s Manual l MY 2019 LEAF Owner’s Manual l MY 2019 LEAF Owner’s Manual l MY2020 LEAF Owner’s Manual l MY2020 LEAF Owner’s Manual l MY 2021 LEAF Owner’s Manual l MY2022 LEAF Owner’s Manual l MY 2023 LEAF Owner’s Manual l MY 2023 LEAF Owner’s Manual l The owner’s manual is a Nissan publication.
3. Total Number of Vehicles Potentially Involved:
Approximately 64,732 Nissan LEAF vehicles may be affected as shown in the table below:
Model Year/ Model Number of Vehicles
MY 2018 – MY 2023 Nissan LEAF 64,732
4. Percentage of Vehicles Estimated to Actually Contain the Noncompliance:
100%
5. Description of the Noncompliance:
Following the Owner’s Manual instructions for defroster operation may result in reduced
defroster performance under specific conditions. More specifically, in very cold
temperatures (below 74° F/-70° C), maximum fan speed can result in the Positive
Temperature Coefficient (“PTC”) heater entering failsafe mode for undercurrent protection,
which can limit defroster output.
This reduced defroster performance can limit visibility out of the windshield, which does not
meet the requirements of 54.3 of Federal Motor Vehicle Safety Standard (FMVSS) No. 103;
Windshield defrosting and defogging systems. The potential for loss of forward visibility
may lead to the increased risk of a crash or injury to the vehicle occupants.
6. Basis for Determination of the Existence of a Noncompliance:
December 22, 2022 – Nissan received preliminary information related to the defroster
operation on a MY 2023 Nissan LEAF vehicle during NHTSA compliance testing. More
specifically, in the course of conducting an FMVSS 103 test procedure, the ·critical area· of
the windshield was not properly cleared in the allotted time.
January 12, 2023 – Nissan met with NHTSA via teleconference to share internal testing data
and analysis. Nissan requested a re-test under modified instructions for testing warm-up.
January 26, 2023 – OVSC rejected Nissan’s request for re-testing.
February 1, 2023 – Nissan made a noncompliance determination for MY 2018-2023 Nissan
LEAF and decided to conduct a Safety Recall. Nissan’s investigation of MY 2013-2017
vehicles was continuing.
March 2023 – Nissan and the supplier conducted additional testing of MY 2013-2017 LEAF
vehicles. Nissan was unable to recreate the subject condition in these models. However,
supplier historical data cannot rule out the possibility that the subject condition may occur.
March 23, 2023 – Out of an abundance of caution, Nissan decided to expand the previously
decided recall population to include MY 2013-2017 Nissan LEAF vehicles.
March 30, 2023 – Nissan submitted an Amended NCIR in 20V-048 to include the MY 2013-
2017 Nissan LEAF vehicles.
April 5-26, 2023 – Pursuant to NHTSA’s request, Nissan has prepared for a separate
voluntary safety recall campaign for MY13-17 Nissan LEAF vehicles. Nissan is submitting an
Amended NCIR for 20V-048 to remove the MY 2013-2017 vehicles, and is submitting a new
Noncompliance Information Report for these vehicles.
Nissan is not aware of any accident or injuries related to the subject condition.
7. Description of Corrective Action:
Nissan notified owners of affected Model Year 2018 to Model Year 2023 LEAF vehicles by
April 1, 2023. Nissan will notify owners of affected Model Year 2013 to Model Year 2017 LEAF
vehicles by May 26, 2023. Dealers were notified on February 7, 2023, and were notified of the
expanded population on March 31, 2023. Nissan will notify dealers of the new separate
voluntary safety recall campaign for MY 2013-2017 Nissan LEAF vehicles on April 27, 2023.
Nissan will provide an Owner’s Manual addendum with updated instructions on how to
operate the defroster under the subject conditions. There will be no charge to customers
for the addendum card.
Nissan will include a statement in the Part 577 owner notification concerning
reimbursement for the cost of obtaining a pre-notification remedy for a subject vehicle
that is no longer under warranty at the time of repair.
8. Copy of Notices:
Copies of all notices will be provided to NHTSA as they become available.

Frequently Asked Questions (FAQ):
Q. Is this a recall?
A. Yes.
Q. Is this a Stop Sale?
A. Yes.
Q. What is the reason for the recall?
A. Following the Owner’s Manual instructions for defroster operation may result in reduced defroster performance under specific conditions. More specifically, in very cold temperatures (below 230 F/-50 C), maximum fan speed can result in the Positive Temperature Coefficient (“PTC”) heater entering failsafe mode for undercurrent protection, which can limit defroster output.
Q. What is the possible effect of the condition?
A. This reduced defroster performance can limit visibility out of the windshield, which does not meet the requirements of S4.3 of Federal Motor Vehicle Safety Standard (FMVSS) No. 103; Windshield defrosting and defogging systems. The potential for loss of forward visibility may lead to the increased risk of a crash or injury to the vehicle occupants.
Q. What will be the corrective action for this voluntary recall campaign?
A. Nissan is providing affected owners with an addendum to the Owner’s Manual with updated instructions on how to operate the defroster under the subject conditions. Customers will be asked to attach the addendum to the vehicle Owner’s Manual. Owners of 2018-2023 Nissan LEAF vehicles will be mailed the addendum with the updated instructions beginning in April 2023, and owners of 2013-2017 Nissan LEAF vehicles will be mailed the addendum with the updated instructions beginning in May 2023.

SAFETY RECALL
CAMPAIGN ID: R22C5 | Original Document
IMPORTANT: It is a violation of Federal law for dealers to sell or deliver vehicles in their inventory covered by this notification until the campaign action is performed.
***** Campaign Summary *****
Nissan is committed to the safety and security of our customers and their passengers. Nissan has notified the National Highway Traffic Safety Administration (NHTSA) that the previously announced quality assurance hold (PC943) for MY2018-2023 LEAF vehicles is being reclassified as a Voluntary Safety Recall Campaign. Nissan is recalling certain MY2018-2023 LEAF vehicles to correct the instructions for defrost operation in very cold temperatures.
Following the Owner’s Manual instructions for defroster operation may result in reduced defroster performance under specific conditions. More specifically, in very cold temperatures (below 230 F/-50 C), maximum fan speed can result in the Positive Temperature Coefficient (“PTC”) heater entering failsafe mode for undercurrent protection, which can limit defroster output. This reduced defroster performance can limit visibility out of the windshield, which does not meet the requirements of S4.3 of Federal Motor Vehicle Safety Standard (FMVSS) No. 103; Windshield defrosting and defogging systems. The potential for loss of forward visibility may lead to the increased risk of a crash or injury to the vehicle occupants.
The dealer will add an addendum to the Owner’s Manual to vehicles in their inventory with updated instructions on how to operate the defroster under the subject conditions, and owners of affected vehicles will be mailed the addendum with the updated instructions to attach to the vehicle’s Owner’s Manual in April 2023.
