“This is the 3rd instance of my car rolling backwards down the driveway. Both the first and second instances of uncontrolled rolling happened in 2016. Only the second instance was caught on camera. I shared the video with Infiniti and was instructed to bring the car in for an inspection. I went in for the inspection in December 2016 and they reported that there were no issues (despite video evidence). Today, December 2, 2022, the car (while gear shifted into park) again rolled down the driveway, across a street and hit my neighbor's house. This was all caught on video as well. …”

“The contact owns a 2016 Infiniti QX50. The contact stated that while driving at an undisclosed speed, she attempted to engage the horn to prevent a collision; however, the horn was inoperable.
