Official summary
Field Service Campaign for Cascadia CTP Reset. Certain vehicles equipped with DTNA's proprietary Common Telematics Platform (CTP) are not communicating and, therefore, are unable to benefit from over-the-air software updates. The CTP will be reset and some will also be initialized.
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.
