NHTSA Complaint #11487085 — 2020 NISSAN LEAF

What component or system failed or malfunctioned, and is it available for inspection upon request? AEB may have malfunctioned. Yes, I will provide the car for official inspection. How was your safety or the safety of others put at risk? Possible injuries from abrupt braking; possible and likely rear-end collision if drivers behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? No. I have not contacted Nissan. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. I have not contacted any gov agency or insurance carrier. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. I saw three red flashes and associated sounds warning of imminent collision - even though NOTHING was in front of the car that would cause the AEB to engage. Below is my incident description: My work has an underground garage. I was entering the garage, went down one level, and then on my way back up the next level. There are speed bumps going down and going up, so you cannot go very fast. On my way back up (incline), the AEB unexpectedly activated with red buttons flashing about three times with sound (as if I was about to crash into something) and then the car abruptly stopped. I stepped on the accelerator to try and go and it would not budge. I'm still on the incline. If there were cars behind me, I would have most likely been rear-ended because this incident came out of nowhere and my car just stopped. There were no moving cars in front of me that would indicate a near collision, only parked cars. I had driven this route in the past so I don't know what was different today. Car just stopped. I am still on incline; placed car in park; waited few seconds; placed car in drive and was finally able to move the car.
