Toyota RAV4 all wheel drive system failure causing shaking and check engine light activation on Toyota RAV4

Some Toyota RAV4 owners report experiencing shaking and the activation of the check engine light due to all-wheel drive (AWD) system failure. Common causes of this issue include sensor failure, dead batteries, faulty transmission components, and even opened gas caps. Owners often find that resetting the AWD system by turning off and restarting the engine can provide temporary relief. However, if the problem persists, they are advised to check tire pressure and sensors, or visit a mechanic to retrieve engine error codes using an OBD-II scanner. For 2017 to 2019 models, ensuring gas caps are tightened and fluid levels are correct is also recommended. It is crucial for owners to diagnose and address these issues promptly, especially when accompanied by a check engine light, to prevent further complications.
