A remote update did not spare some owners of the 2025 Chevrolet Tahoe and Suburban a trip to the service department. General Motors has found that certain infotainment modules failed to complete an over-the-air software installation, so the software now has to be updated manually at a dealership. This is a service program, not a safety recall.

The campaign is numbered N262545571 and has been in effect since August 18, 2026; in the NHTSA database it is filed as manufacturer communication 11036227. Before any work is done, the dealer must check the vehicle’s VIN in the GM Global Warranty Management system: the program does not apply to every Tahoe and Suburban. The automaker has not yet said exactly how many vehicles are affected. The issue may concern the front or rear audio and video module, or both at once.

Simply restarting the update may not be enough: GM’s instructions note that some modules are several software versions behind, so the Delta Programming procedure may have to be performed up to three times. No parts need replacing. The fix is free of charge until August 31, 2028. GM allots about 0.7 hours of labor time to reprogram a single module and about 1.3 hours for the front and rear modules together.

Owners in the United States and Canada will receive letters inviting them to book a dealer appointment. And the program is not limited to the two Chevrolets: the same software defect affects certain 2025 Cadillac Escalade, Escalade ESV and electric Escalade IQ models, as well as the 2025 GMC Yukon and Yukon XL. The result is a single service campaign covering nearly the entire current lineup of the group’s full-size SUVs. Nor is it the first technical fix for GM’s big SUVs this year.

Earlier, the automaker addressed wind noise in the 2025 and 2026 Tahoe, Suburban, Yukon and Escalade, while Chevrolet has meanwhile prepared new Adventure packages for the 2026 Tahoe and Suburban.

The case neatly exposes the weak spot of the OTA scheme: once a module falls too far behind on software or an installation is interrupted, the ability to update the vehicle without a workshop visit disappears. Here the owner will not have to pay for repairs or new parts, but the fix will no longer be fully remote.
