2016-2021 Hyundai Tucson Power Seat Track: Fixing a Stuck, Slow, or Noisy Driver's Seat
This guide covers the common failures, diagnosis, and replacement options for the driver's side power seat track in the 2016-2021 Hyundai Tucson.
- Verify compatibility: This track is for the driver's side, 8-way power seat WITHOUT the ventilated/cooled seat option.
- If the seat works in some directions but not others, the problem is likely the switch, not the track or motor.
- Disconnecting the battery is mandatory before unplugging any wires under the seat to prevent airbag deployment.
- Buying a used OEM track can save over $600 compared to a new part from the dealer.
Symptoms of a Failing Seat Track Bracket
Power seat problems can be caused by a bad switch, a faulty motor, a wiring issue, or a mechanical jam. It's important to identify the specific symptom to narrow down the cause.
Seat Won't Move At All and Makes No Noise
If you press any of the seat adjustment buttons and hear nothing, the problem is likely electrical. Before suspecting the seat track itself, check the fuse for the power seats in your vehicle's fuse box. 🎬 Watch: How to find and check your power seat fuses. If the fuse is good, the next most likely culprit is the main power connection to the seat or the power seat switch assembly itself.
Seat Moves in Some Directions But Not Others
This is one of the most common complaints for this vehicle. For example, the seat may recline back but refuse to come forward, or it will go down but not up. This symptom almost always points to a faulty power seat switch, not the motor or track. The electrical contacts inside the switch for that specific direction wear out or get dirty. Sometimes, the switch can be removed and the contacts cleaned to restore function, but replacing the switch assembly is a more permanent fix.
🎬 See this video on how the power seat switch functions.Grinding, Clicking, or Whining Noises
If you hear a motor running or making noise but the seat doesn't move, or moves with a grinding or clicking sound, the problem is likely mechanical. This indicates a stripped gear inside the motor's gearbox or an issue with the drive cable that connects the motor to the track mechanism. In this case, the motor is receiving power, but it can't transfer that motion to the seat track.
Seat is Loose or Rocks
A seat that feels loose, rocks during acceleration or braking, or has a noticeable wobble is often a sign of a problem with the seat track assembly itself. This could be caused by worn-out bushings, loose mounting bolts (where the track bolts to the floor or the seat bolts to the track), or a crack in the frame. This should be addressed immediately as it is a significant safety concern.
Buying a Used 2016-2021 Tucson Seat Track
A used OEM seat track assembly is a smart, cost-effective solution, especially since a new OEM unit is very expensive and complete aftermarket assemblies are generally not available. However, careful inspection and verification are critical.
Compatibility is Crucial: Read This Before You Buy
You must purchase a track that exactly matches the features of your original seat. Failure to do so will result in components that won't work or connectors that don't match up.
Compatibility Warnings:
- Power vs. Manual: This power seat track cannot be used to upgrade a manual-seat vehicle. The wiring and mounting points are different.
- Driver's Side Only: This is a driver's side (left-hand) track. It is not interchangeable with the passenger side.
- Ventilated Seats: The most important check is for the ventilated seat option. OEM catalogs show a different, more expensive part for models with heated AND ventilated (cooled) seats. This guide and part are for the 8-way power seat without the ventilation feature. Ensure the donor vehicle did not have ventilated seats.
What to Inspect on a Used Seat Track
- Check the Wiring: Inspect the entire wiring harness that is part of the track. Look for any cut, frayed, or repaired wires. Ensure all plastic connector plugs are intact, not cracked, and have no signs of corrosion or burning on the pins.
- Examine the Rails: Look for any signs of bending, cracking, or significant rust on the metal rails. Minor surface rust can be cleaned, but deep, flaking rust compromises the part's strength.
- Test the Motors (If Possible): If you can, bring a 12V power source (like a jump pack) to test the motors. Apply power directly to the pins of each motor connector to verify it spins.
- Look for Water Damage: Check for rust or corrosion at the very bottom of the track, which could indicate it came from a flood-damaged vehicle. Avoid these parts entirely.
Known Issues, TSBs, and Recalls
As of early 2026, there are no official recalls or Technical Service Bulletins (TSBs) from Hyundai specifically for power seat track or motor failure on the 2016-2021 Tucson in the North American market. While recalls exist for other Hyundai models or other seat components like seat belts, they do not apply to this specific part and vehicle combination. The most widely reported issue by owners in forums is the failure of the power seat control switch, which is a separate part from the track and motor assembly.
Replacement Information
Replacing the entire seat track assembly involves removing the entire driver's seat from the vehicle.
- Difficulty Rating: 3 out of 5
- Estimated Time: 1.5 - 2.5 hours
- DIY Feasible: Yes, for individuals comfortable with basic hand tools and proper safety procedures.
Warning: Airbag System Safety
The driver's seat contains an airbag and is connected to the vehicle's safety restraint system (SRS). To prevent accidental airbag deployment and personal injury, you MUST disconnect the negative terminal of the vehicle's 12V battery and wait at least 15 minutes before unplugging any connectors under the seat. The yellow connectors are specifically for the SRS/airbag system 🎬 Watch: A step-by-step guide to front seat removal and repair. and must be handled with care.
Basic Replacement Steps
- Disconnect the negative battery terminal and wait 15 minutes.
- Move the seat to a neutral position to access all four mounting bolts on the floor. If the seat is stuck, you may need to manually power the motor or try to force it to move to get to the bolts.
- Remove the plastic covers over the bolts at the end of the seat rails.
- Unbolt the four main bolts holding the seat track to the vehicle floor.
- Carefully tilt the seat to access and disconnect all electrical connectors underneath. Pay special attention to the yellow airbag connector.
- Remove the heavy and awkward seat assembly from the vehicle.
- With the seat on a workbench, unbolt the seat cushion and back from the old track and transfer them to the new track assembly.
- Installation is the reverse of removal. Ensure all connectors are securely clipped in before reconnecting the battery. Torque the seat bolts to the manufacturer's specification.

Frequently Asked Questions (FAQ)
My seat only stopped working in one direction. Is the whole track bad?
Almost certainly not. If the seat moves in some directions but not others, the problem is most likely a faulty power seat switch on the side of the seat, not the motor or track. This is a much cheaper and easier part to replace.
Can I just replace the bad motor instead of the whole track assembly?
Yes, this is often possible. The individual motors (for slide, recline, and height) are typically bolted to the track assembly and can be swapped out. This can be a cost-effective repair if you can find the correct used motor and are comfortable with the disassembly required. However, you must match the motor exactly, as they are not interchangeable between functions.
Do I have to disconnect the battery to replace the seat track?
ABSOLUTELY YES. The seat contains a side airbag and is connected to the main SRS (airbag) system. Failing to disconnect the battery before unplugging the seat's electrical connectors can cause the airbags to deploy, leading to serious injury and expensive repairs. It can also trigger an airbag warning light that requires a dealer to reset.
My seat is stuck all the way back and I can't reach the front bolts. What do I do?
This is a tough situation. First, double-check if the problem is the switch. You can try bypassing the switch by applying 12V power directly to the forward/backward slide motor's connector pins to try and move it. If the motor is dead, you may have to unbolt the seat cushion from the track while it's in the car to get better access to the track's mounting bolts, which can be very difficult.
