Official NHTSA campaign record

Why the reported issue matters

Wheel lock-up while driving increases 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 transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025. Owners may contact Cadillac customer service at 1-800-333-4223 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242480630.

Official NHTSA campaign record

This describes the dated source record. Current arrangements for your VIN remain unconfirmed.

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 25V148000 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 component: POWER TRAIN:AUTOMATIC TRANSMISSION.

  4. Which module and software completion record demonstrate that the update for 25V148000 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 25V148000, 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.
