Hatchback/liftgate Support Device problems of the 2015 Chevrolet Tahoe

The liftgate malfunction is both bizarre and dangerous. When opened it proceeds to drop about a foot quickly, enough to create serious head contact. It then proceeds to close without use of sensors, repeatedly pinning the operator against the back of the car. Only with strength and agility did my wife manage to slide out the side. We are thankful that the only damage was a bruise on her leg. It could have been much worse for an older, less agile person. It happens when vehicle is stationary, on or off. The dealer plans to replace the liftgate actuator, but it will be at our expense. Chevy has declined coverage because we are not the original owner, we did not buy it from a chevy dealer and we did not purchase extended warranty coverage. There is no recall outstanding so they have no obligation to help us. Had my wife gone to a doctor for the bruise on her leg chevy's decision would have gone to a different supervisor, but we do not act that way. We are just grateful that she had the wherewithal to escape from a very dangerous situation. I have a video of the problem, but it is not in a format (imov) that can be uploaded here. I will hold on to it.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that the liftgate sensor became inoperable whenever the sensor was touched. On several occasions, the liftgate independently opened or closed. The vehicle was taken to a dealer where it was diagnosed that the foot sensor could not be deactivated. The vehicle was not repaired. The manufacturer was notified of the defect. The contact wanted the sensor deactivated. The failure mileage was approximately 4,400.
