We see a common problem with this model: the 4x4 and ABS warning lights are constantly on, the car does not drive well, and it seems to be stuck in engine braking. In 90% of cases, the actuator of the transfer case is faulty.

This component is controlled by the 4x4 module (called ATC) and sends signals to manage traction. If it gets stuck in the "engaged" position, it virtually locks the center differential, causing the described symptoms.

The solution is to replace the actuator, which is located at the back of the transfer case in a very tight spot, often requiring the removal of other components, the use of extension tools to reach the area, and a lot of patience. This is a mechanically complex job, where the diagnosis is simple, but the repair is technically challenging and should be entrusted to professionals.

How to Remove the Rear Seat of a Hyundai Tucson?

To remove the rear seat of a Hyundai Tucson, follow these steps. Start by moving the front seats to their most forward position to gain space. Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
