Prepare your observation

Keep existing warning or braking observations for the service provider. Do not conduct braking tests or work under the vehicle from this guide.

A reported defect describes the campaign. It does not establish what caused a symptom on your individual vehicle, and absence of a symptom does not establish that an open recall is complete.

The reported manufacturer remedy

Dealers will recalibrate the brake system control module, free of charge. Owner notification letters were mailed on August 27, 2021. Owners may contact Chevrolet customer service at 1-800-222-1202; GMC customer service at 1-800-462-8782. GM's number for this recall is N212340970.

Your campaign-specific service questions

Use these questions with the official report. Keep the answers beside the remedy record; “discussed” records a conversation, not a completed repair.

  1. Does the manufacturer confirm that campaign 21V579000 applies to this VIN, including the report’s equipment and production restrictions?

    A matching model and year is only a starting point. The official lookup or manufacturer must establish the individual vehicle’s status.

  2. What remedy, required parts or software, and appointment arrangements are currently available for this VIN, and which interim instructions apply?

    The source does not explicitly establish current remedy availability. Ask the manufacturer about the applicable remedy, required parts or software, appointment arrangements and any interim instructions.

  3. Which braking or stability-control function is involved, and what current use or transport guidance applies to this VIN?

    Compare the answer with the reported component: SERVICE BRAKES, HYDRAULIC:POWER ASSIST:ELECTRIC:CONTROL MODULE:SOFTWARE.

  4. Which reported corrective actions (recalibrate) were performed under 21V579000, and which component or function did they address?

    Compare the provider’s answer with the exact remedy below. Keep the action and affected component on the work order; ordinary maintenance or a visual check may describe different work.

  5. What dated document records the remedy performed under 21V579000, and what should I do if the reported concern remains?

    Keep campaign completion and unresolved symptoms as separate questions. A saved worksheet or booked appointment does not establish a repair.
