The GM Technical Assistance Center, or TAC, (U.S.) has established an Action Center for the all-new 2022 HUMMER EV. (Fig. 8)
Fig. 8
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 HUMMER EV has a direct connection to GM Engineering, Brand Quality and the Factory Zero 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 HUMMER EV 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 HUMMER EV 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 HUMMER EV unique parts have been placed on TAC restriction to help understand part failures, which will 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 HUMMER EV parts.
The following TAC Part Restriction PI’s are available to aid in part restriction processing:
- PIT5857: 2022 GMC HUMMER EV TAC Restriction Battery Pack
- PIT5858: 2022 GMC HUMMER EV TAC Restriction Unique Parts
- PIT5859: 2022 GMC HUMMER EV TAC Restriction ESC Parts
For more information on the 2022 HUMMER EV as well as additional training opportunities on HUMMER EV systems, refer to Bulletin #21-NA-295.
