1,849 Cadillac communications on file with a page here: 1612 service bulletins, 135 service campaigns, 94 over-the-air updates, 5 warranty extensions, 2 emissions, 1 other. Every bulletin a Cadillac model-year page lists, plus every service campaign, warranty extension, over-the-air update and emissions notice Cadillac filed since 2016, whether or not the vehicle has a page.

Cadillac’s warranty extensions and special-coverage programs are also in their own list and one list with every other make’s, with the term each runs to.
