What is the reason for the car not moving after releasing the handbrake?
2 Answers
Releasing the handbrake but the car not moving can be caused by the following reasons: Brake system malfunction: If the brake is not fully released, the car won't move even when accelerating. Some vehicles require stepping on the brake pedal once to completely disengage the electronic handbrake. Transmission control unit failure: If the transmission fails to disengage from P (Park) mode, the vehicle won't move. If the car still doesn't move after shifting to D (Drive) gear, it might indicate an electronic control system malfunction. Transmission failure: If there's a malfunction in the transmission's internal drive system, the vehicle won't move. Carefully observe the dashboard warning lights to see if any brake, transmission, engine, or other warning lights are illuminated. If present, consult a mechanic to determine if they're related to the vehicle's inability to move.
As an auto mechanic, I've seen this situation many times. The most common cause is the parking brake not being fully released, such as when the cable gets stuck or the spring fails. In damp or cold weather, brake pads can freeze and stick to the rotors, causing the wheels to lock. First, try gently pressing the accelerator for a few seconds to see if it can break free; if not, don't force it to avoid damaging the brake system. It's possible that the tire is stuck by debris or the ground is uneven, so check under the car and remove any obstructions. This happens more often when parking on a slope—after getting out, try pushing the car to see if it loosens. Regular maintenance, like lubricating the brake cables, can prevent this. A typical adjustment at a repair shop takes only about half an hour and isn't expensive. Remember, safety first—never attempt to fix this yourself at a traffic intersection.
