Toyota RAV4 engine shut off in reverse on incline causing brake failure on Toyota RAV4

Some Toyota RAV4 owners report experiencing engine shutdowns when reversing on an incline, which can lead to brake failure. This issue may occur due to the vehicle's idle stop feature activating when the brake is fully depressed, but it can also stem from serious problems such as vacuum leaks, blown fuses, or faulty idle control valves. Additionally, some drivers have noted that vigorous driving or abrupt maneuvers can trigger these shutdowns, particularly during right turns or hard stops. While the engine may restart immediately after shutting off, it is crucial for owners to address the underlying causes to prevent recurrence. Proper procedures, such as ensuring the parking brake is set before shifting into Park, are essential for safety in these situations.
