Instructions

Follow these steps to safely replace your 2017 Sorento’s burnt-out brake light bulbs:

1. Open the Trunk

Pop open the rear hatch of your Sorento and locate the vehicle’s tail light assemblies on the left and right sides.

2. Remove Two Screws

You’ll notice two Phillips head screws holding each unit in place. Use your flathead screwdriver to back these screws out counterclockwise.

3. Pull Out the Assembly

Once the screws are out, gently pull the entire tail light assembly straight back. A few firm tugs should release the whole piece. Detach the electrical harness by squeezing its release tab.

4. Remove the Bad Bulb

Now comes the burnt-out bulb causing all this trouble! Twist the faulty brake light bulb counterclockwise to release it, then extract it from the assembly.

5. Insert the Replacement

Take your fresh 1157 replacement bulb and align its tabs with the socket holes. Push in gently and twist clockwise to lock the new bulb into place.

6. Re-install the Assembly

Reconnect the electrical harness to the tail light assembly. Align the assembly with its brackets, then push it back into place. Hand tighten the two Phillips screws to secure everything.

7. Test Your Work

Close the hatch and hop in the driver seat. Press the brake pedal and verify the bright glow of your working brake lights in another vehicle’s mirrors or a window’s reflection.

Helpful Replacement Tips

To ensure safe, successful brake light bulb replacement in your 2017 Sorento, keep these pointers in mind:

  • Don’t force anything! Wiggling stuck bulbs or connectors gently is better than breaking something.
  • Triple check your new 1157 bulb type before buying. Using the wrong bulb can blow a fuse.
  • Avoid touching the new bulbs with bare fingers. Oil from your skin leaves residue affecting performance.
  • Don’t overtighten any screws when re-installing assemblies. Snug is fine!
  • Still not working? Check bulb alignment or try replacing the second bulb too.
