General Motors has issued a Service Update to address an issue related to the telematic control module in certain 2021 model-year Cadillac Escalade models.
The problem: affected 2021 Cadillac Escalade vehicles may have a condition where the onboard telematic control module is unable to receive over-the-air updates from General Motors.
The hazards: while this problem does not pose an immediate safety risk to vehicle occupants, it is important that a vehicle be able to receive over-the-air updates, as these can remotely address problems like infotainment system bugs and issues with the vehicle’s control electronics, among more. Over-the-air updates are therefore important to the vehicle’s overall running operation.
The fix: GM dealers will be instructed to replace the entire telematic control module in affected vehicles. These repairs, which should enable the vehicle to begin receiving over-the-air updates, will be performed at no cost to the vehicle owner.
Affected components: telematic control module.
Number of affected vehicles: GM did not say how many vehicles may be affected by this particular issue.
Next steps: Customers will be contacted about this Service Update and will be instructed to make an appointment with a Cadillac dealership. The service bulletin involves vehicles in dealer inventory and customer vehicles that return to the dealer for any reason and will expire at the end of the involved vehicle’s New Vehicle Limited Warranty period. The bulletin was first issued in July 2021. Customers with additional questions and concerns can also reach out to Cadillac directly using the contact information included directly below.
