Official summary
Certain GV70 (JK1A) vehicles equipped with 3.5 T-GDI Lambda III engines may exhibit a malfunction indicator light with DTC P26CB00 (Engine Coolant Pump Performance/Stuck Off). This may be caused by a stuck impeller on the electric water pump (EWP) for the water-cooled intercooler. The California Air Resources Board has determined that these vehicles may be releasing air pollutants which exceed Federal and California standards.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
