Common Causes

The RAV4 electric power steering warning light can illuminate due to several issues. A weak battery is often the primary culprit, as the power steering system relies heavily on electrical power. If the battery is low on charge, the steering may become sluggish or unresponsive. Water damage is another significant concern, particularly in certain 2019-2020 RAV4 models affected by a recall. Water infiltration into the steering gearbox can lead to system failure.
