Summary of the problem: The rear liftgate on my Rivian failed to detect an obstruction while closing and continued to close despite contact with a person. What happened: While the rear liftgate was automatically closing, I was unaware it was coming down and walked into it. The liftgate made contact with my upper body/face and did not stop or reverse as expected. Instead, it continued closing and forced me to the ground. Safety issue: The liftgateâs safety sensor failed to detect a human obstruction, creating a serious risk of injury. This is especially dangerous for children or shorter individuals who may be struck in the head or face. Injuries: I sustained bruising to my face and was knocked to the ground as a result of the liftgate continuing to close after impact. Why this is dangerous: A properly functioning power liftgate should stop and reverse when it encounters resistance. This system failed entirely, posing a significant safety hazard. There were no warnings or components that alerted before or after it failed to sense.
