Cadillac and Camaro transmission may lock the wheels

NHTSA campaign 25V148000 · Reported 2025-03-06 · General Motors, LLC

high How serious is it? About this label

Wheels locking up while driving is serious and can happen without warning, though the notice does not instruct owners to stop driving the vehicle.

What's wrong, in plain English

Certain Cadillac CT4, CT5, CT6 and Chevrolet Camaro models with the 10-speed automatic transmission can suffer internal damage inside the transmission. If that happens, the wheels can suddenly lock up, meaning they stop turning while you are driving and you lose control of the car. GM dealers will install new monitoring software in the transmission's computer so the problem can be caught, and the work costs you nothing.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your car is affected. 2. Contact your dealer, or Cadillac at 1-800-333-4223 or Chevrolet at 1-800-222-1020, and mention recall N242480630. 3. Schedule the free software installation.
