Some 2024 Chevy Blazer EV Units Will Need A Serial Data Gateway Module Fix

GM has issued two Customer Satisfaction Programs for certain units of the 2024 Chevy Blazer EV which may have a condition in which over-the-air updates are not available, with a fix now offered for this problem.

Per Customer Satisfaction Program numbers N242452320 and N242452321, Chevy Blazer EV units affected by the issue are marked as “Open” in the Investigate Vehicle History screen of the GM Global Warranty Management system, enabling service personnel to verify involvement prior to work.

The fix that is available for affected 2024 Chevy Blazer EV units requires no additional parts or components. Instead, service personnel are instructed to reprogram the serial data gateway module of the crossover, which will resolve the problem. The fix is available free of charge until October 31st, 2026.

The Chevy Blazer EV has experienced several rather similar problems in the past. These include a remedy offered starting in November 2023 for an issue in which the battery was drained following OTA updates, likely due to the infotainment system remaining active when the update failed and a dead battery resulting overnight. Another update in March helped to optimize future over-the-air updates.

    Whatever. My ICE Silverado will get new plugs at 100k miles.

    As a Blazer EV owner how do you know if you need this service? Why was this article half filler about the stats of the Blazer EV?

      Wondering the same thing myself. Haven’t gotten any updates since I bought the car.
