Why doesn't an automatic transmission car move when releasing the brake in reverse?
1 Answers
Automatic transmission cars not moving when releasing the brake in reverse could be due to the auto-hold function being activated. Disabling the auto-hold function will resolve this issue. Enabling this function enhances safety when waiting at traffic lights or crossing pedestrian crossings, as the vehicle won't move without pressing the accelerator. Once the auto-hold function is deactivated, the car will move forward or reverse upon releasing the brake. There are several reasons why an automatic transmission car might not move when releasing the brake: 1. On very steep slopes, it's normal for the car not to move when releasing the brake. The steepness increases resistance due to inertia, and the car requires sufficient forward power to overcome this resistance. 2. Some car models have transmission settings that prevent movement without pressing the accelerator. 3. If none of the above applies, the car may have a mechanical issue. Potential causes include problems with the transmission, drivetrain, throttle, etc. A professional diagnosis at a 4S shop is necessary to identify the exact issue.
