Subaru Outback Won't Move When Engine Cold - Brake/Steering Issue
The vehicle is in gear but won't move when the engine is cold, suggesting a possible brake drag, steering lock, or transmission issue. Cold weather can cause brake calipers to seize or power steering fluid to thicken, but a stuck brake caliper is the most likely cause.
Diagnosis Details
Possible Causes
Frozen or seized brake caliper (often rear) due to corrosion or moisture, causing the brake to remain engaged when cold.
Parking brake cable frozen or stuck in the engaged position, preventing wheel rotation.
Low or contaminated automatic transmission fluid causing delayed engagement or torque converter issues in cold weather.
