Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was a passenger in my Infiniti QX80 going about 25 +/- . There were 3 beeps and the car suddenly breaked on its own in the middle of the street. I looked up to find nothing in front of us. The driver said the car breaked suddenly on its own! Her foot was on the gas peddle and when she reacted by going for the break it was already to the floor. There was absolutely no reason for this emergency collision feature to go off. Luckily there was no one close enough behind us to rearend us, although I'm certain the driver wondered why we slammed on our breaks in the middle of the street. …”
NHTSA complaint #10715885, filed 2015-05, 1,500 miles“Driving down a city street at about 25-30 MPH with no cars in close proximity in front of vehicle. Heard three quick beeps and then the car suddenly stopped in the middle of the street. Moved foot from gas peddle to the brake to find the brake to the floor. No injuries or damage was sustained. The vehicle was driven directly to the dealer where they can not duplicate the problem. Infiniti consumer affairs department was contacted. They agreed with dealer that it could not be duplicated. Could not tell us if similar complaints have been filed regarding the feb safety feature of the QX80.”
