To help gather product feedback on the new 2026 Corvette ZR1X (Fig. 4), an Action Center has been established by the GM Technical Assistance Center (TAC) for U.S. dealerships

TAC Action Centers are designed to review 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.
he TAC Action Center for the new ZR1X 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 ZR1X model in your dealership, create a TAC case or Techline case using the CX Connect system. Please indicate in the Case Assessment whether assistance is needed or if you are simply sharing product feedback with the team.
Once a case has been submitted, your concern will be directed to a ZR1X specialist who will record the concern and provide diagnostic direction as needed through the CX Connect system. After the 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. Refer to Bulletin #23-NA-103 for tips on taking pictures.
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 on new models as quickly as possible.
Parts Restrictions
A few select parts for the ZR1X are on TAC restriction. These will be indicated with a NOTE in the Electronic Parts Catalog at time of order. Starting a TAC case for any issue will allow the team to ensure needed parts are available quickly to complete the repair. Refer to #PIC6605 for help on how to obtain restricted parts.
