Official NHTSA campaign record

Why the reported issue matters

Rear wheel lock-up can increase the risk of a crash.

Official NHTSA campaign record

Prepare your observation

Record an existing symptom and its date. Do not reproduce a loss of power, stall or transmission fault in traffic.

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 install new transmission control module software, free of charge. GM will provide a special coverage program to cover the repair of transmissions that are identified by the remedy software as containing a defective control valve. Owner notification letters were mailed December 12, 2024. Owners may contact GM customer service at 1-888-988-7267, Cadillac customer service at 1-800-458-8006, GMC customer service at GMC 1-800-462-8782 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242454440.

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 24V797000 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 engine or transmission component is covered, and does an existing drivability problem need separate diagnosis?

    Compare the answer with the reported components: POWER TRAIN:AUTOMATIC TRANSMISSION:FLUID/LUBRICANT:VALVES/VALVE BODY; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE.

  4. Which module and software completion record demonstrate that the update for 24V797000 was applied?

    Ask the service provider how the campaign-specific software remedy is documented. A dashboard reset is not evidence of the specified update.

  5. What dated document records the remedy performed under 24V797000, 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.
