2022 Kia Niro Ev TSBs

INVERTER COOLANT (SA512) - This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides information to flush out the inverter low-conductivity coolant (BSC-1) on certain 2019-2022MY Niro EV (DE EV) vehicles produced from May 10, 2019 through October 4, 2021, which may exhibit a Refill inverter coolant message displayed on the instrument cluster due to poor flow of coolant/antifreeze inside the coolant pipes. In most cases, the inverter reservoir tank coolant may be filled to normal level and no DTCs are stored due to an increase operation of the electric water pump (EWP) that is 2,450 RPMs or more when checked.

of reports of unexpected drainage of the 12-volt battery in some Kia electric vehicles (EVs). While Kias investigation is ongoing, a possible cause of the issue may be third-party applications used by the customer that are causing excessive Kia Connect connections to the customers EV.

New/revised sections of this bulletin are indicated by a black bar in the margin area.This bulletin provides the procedure to update the software logic of the Battery Management System (BMS) on some 2019-2022MY Niro EV (DE EV) vehicles produced from December 5, 2018 through April 12, 2022. The BMS ECU monitors voltage deviation between battery cells, poor insulation, abnormal cell voltage changes after charging, abnormal current change during charging, over-voltage, temperature deviation or average cell deviation during driving is detected. These conditions can cause the BMU to set DTC P1AA600. The affected vehicles may exhibit a reduction in power and speed (limp home mode) and a MIL 'ON' with DTC P1AA600 stored. This BMS DTC logic improvement will expand DTC P1AA600 into multiple DTCs to aid in proper diagnosis, which reduces the required time and steps outlined in the 'DTC Inspection' on KGIS to determine the fault using 'freeze frame' data.

Parking Distance Warning (PDW) alerts and repairs involving ultrasonic sensors. The PDW system alerts the driver while parking, by calculating distance based on the difference in signal transmission and reception times between the vehicle (ultrasonic sensor) and an object. The membrane film of the ultrasonic sensor is used for object detention and can be damaged by stone chips or foreign substances while driving. Damage to the cover of the ultrasonic sensor can also lead to damage to the internal circuit. As a result of this external damage, the PDW system may not receive the proper signal from the ultrasonic sensor. In some cases, the system may cause a false alarm, no alert, or phantom warnings by a Warning Lamp to be displayed on the cluster. The ultrasonic sensor membrane film should be always inspected for external damage and if any part replacement should be treated as a general repair, not as a warranty claim repair for this concern. (Please note that this Pitstop only applies to models/trims that are equipped with the ultrasonic sensors.)

This bulletin has been revised to include additional information. New/revised sections of this bulletin are indicated by a black bar in the margin area. This bulletin provides the procedure to inspect the Integrated Electronic Booster (IEB) on certain 2019-2022MY Niro EV (DE EV) vehicles produced from December 5, 2018 through April 12, 2022, that were originally sold or are currently registered in one of the 28 states where heavy amounts of road salt are used. Over time, saltwater inflow into the Integrated IEB at the IEB fastening bolt hole may cause corrosion and lead to an inoperable IEB motor. Should this occur, the vehicle may experience illumination of the Anti-lock Brake System (ABS), Forward Collision-Avoidance Assist (FCA) warning lights, and/or a firmer brake pedal feel. The brakes remain operational. Kia is conducting this service campaign to improve corrosion resistance of the IEB assembly.

New/revised sections of this bulletin are indicated by a black bar in the margin area. This Pitstop provides information regarding the Rear Occupant Alert (ROA) with Rear Door Logic system on all 21MY~ models equipped with this feature. This system is designed to help prevent a rear passenger from being left inside the vehicle when exiting. The "Check Rear Seats" message will display on the cluster when driver opens the front door, if during vehicle operation the rear doors (one or both) were opened and closed.

New/revised sections of this bulletin are indicated by a black bar in the margin area. This pitstop provides the KDS service procedure for mileage setting on the models listed below with newly replaced instrument clusters. Certain models allow for mileage setting with the KDS, which prevents the need to send out the instrument cluster to a 3rd party for mileage adjustment (refer to PS264). After a new cluster is installed, cluster (variant) coding may also need to be conducted using the KDS. Make sure the KDS software is also updated to the latest version. Mileage setting should be performed by using the KDS only, as described in this bulletin.
