    Check bulb holder and mounting area for burnt contacts. Also checked the wiring connector they can burn as well.

    I'm not sure if the new models have the same issue, but check the wiring loom feeding from the body to the trunk. I know on my model it's a common issue that over time, the constant opening and closing of the trunk causes the wires to snap. I had to solder about half of the wires feeding the back end lights (backup, tail light, license plate, etc.).
