Step 1
Open the trunk and remove the two hex screws securing the rear bumper fascia with a 5mm allen wrench as shown. One on each side of the vehicle.
2022 models and newer: Remove the taillight finish plate to expose threaded fastener. Use a 10mm socket to remove the fastener. There will be one fastener located on each side of the vehicle.   Step 2
Using short Philips and flathead screwdrivers, remove the screws and plastic rivets in the fascia panel as shown.
2022 models and newer: The upper-most fastener inside the wheel well is slightly hidden and is securing the bumper fascia right at the fascia seam line. Step 3
Gently pull the fascia up from the rear wheel trim panel on each side of the vehicle. Work up to the taillights and continue to remove along the bottom of the taillights to the bottom of the trunk.
After the panel is loose all around, remove the bumper fascia and set it aside.

Remove the eight bolts securing the bumper.
CAUTION
