Owner complaint summary

About six months ago the tailgate foot sensor failed and has not worked. Since then, the tailgate began randomly opening on its own, mostly when the car is parked and shut off, but as of today(4-28-2026) it started occurring while I'm driving. In addition to the hazard of items falling from my vehicle unto the highway and/or other cars, the only way for me to close the tailgate from the driver's seat is to place the transmission in Park and push the tailgate button. Other than that, I must stop and get out and physically close it. Both actions are potential risks depending on my location and the traffic around me. I've brought this in to the dealership service department in January 2026 with this complaint, but was told they couldn't find anything wrong with it. In the meantime, it continues to get worse.

This is an owner complaint filed with NHTSA (ODI #11734364). It is not automatically an official recall, investigation outcome, or manufacturer admission unless the complaint text itself describes one.
