Coolant leak from the loose electric water pump hose on the Niro EV

Sources are not verified in real time and no entry confirms that your car is affected.

Engine / equipment: Niro EV (II) electric
Period mentioned: 2022–2024
Symptoms: A "refill coolant" message on the dashboard and a heater that warms less and less; sometimes drops of fluid under the front.
Possible cause described: The hose from the electric water pump to the high-voltage battery comes loose at its connector, because the retainer clip was fitted horizontally, and leaks coolant under the bulkhead. Kia fits an improved hose with the clip rotated 90° (bulletin ELE332, April 2024, for Niro EVs built from 11/7/2022 to 24/1/2024).
Check for the garage: Do not open the coolant reservoir when hot. It is a high-voltage car: at a qualified garage, have them check the electric water pump hose connector.
