TAC Action Centers are designed to gather early product feedback and provide support for the introduction of new GM models. Dealership service departments are asked to report all vehicle issues that require immediate attention, not just concerns that require technical assistance. The goal is to develop a quick resolution to any product concerns, such as fit and finish, performance, and operation, as well as to address customer expectations of the vehicle.

TAC Action Centers have a direct connection to GM Engineering, Brand Quality and the assembly plant, which offer combined resources to immediately address product concerns seen in the dealership.

Contacting the TAC Action Center

If any concerns are encountered with a new Tahoe/Suburban or Yukon/XL in your dealership, create a TAC case using the Dealer Case Management (DCM) system. Refer to the latest version of Bulletin #08-00-89-014 for more information on using the DCM system.

Once a case has been submitted, your concern will be answered by a Tahoe/Suburban or Yukon/XL specialist who will provide diagnostic direction as needed through the DCM system. After a case has been started, feel free to contact the TAC if any additional support is needed.

Case Details

Service department personnel are encouraged to contact the action center to report all product concerns and provide digital photos of a concern when applicable. Photos are extremely important to show engineering where the concern is located, whether it’s a pinched harness or a backed out terminal.

It is imperative to follow up on an action center case, even if it’s as simple as a “cannot duplicate” concern or waiting for parts. All case information is reviewed daily and used by GM to resolve launch issues as quickly as possible.

For additional information on the 2021 Tahoe/Suburban and Yukon/XL, refer to Bulletin #20-NA-137 and training courses 10220.04 (April 2020 Emerging Issues) and 10321.20W (2021 Chevrolet Tahoe, GMC Yukon New Model Launch).
