Brake or Steering Issue: Car Won't Move When Cold
The vehicle is in gear but refuses to move when the engine is cold. This suggests a potential brake drag, seized caliper, or transmission-related problem. The cold condition may cause components to bind or fluid to thicken, preventing normal operation.
Diagnosis Details
Possible Causes
Frozen or seized brake caliper (especially if brake pedal feels hard or car pulls to one side)
Transmission fluid low or degraded (cold thickening can prevent engagement)
Parking brake stuck or cable frozen (common in cold weather)
Steering rack or power steering issue causing binding (less common with no movement)

Check brake fluid level and condition.
Inspect all four wheels for signs of brake drag (hot wheel, smell).

If safe, try gently rocking the car or applying light throttle to see if it breaks free.
If not, have the vehicle towed to a shop for brake and transmission diagnosis.
