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.

The TAC Action Center for the LYRIQ EV has a direct connection to GM Engineering, Brand Quality and the assembly plant, which offer combined resources to address product concerns seen in the dealership.

Contacting the TAC Action Center

If any concerns are encountered with a new LYRIQ 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 escalated to a LYRIQ specialist who will call the dealership to provide diagnostic direction and support. After a case has been started, feel free to contact the TAC if any additional support is needed.

Service department personnel are encouraged to report all product concerns and provide GDS session logs and digital photos of a concern when possible. Photos are extremely important to show engineering where the concern is located.

In addition, it’s 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.

Part Restrictions

All LYRIQ unique parts have been placed on TAC restriction to help understand part failures, which can help drive faster root cause analysis. TAC will help with replacement part identification as necessary as well as provide support with SPAC cases on both common and unique LYRIQ parts.
