“While driving down a four lane highway at 50 MPH. The car suddenly applies emergency braking when nothing was in front of the car. If another car is behind this vehicle and this happens, there will be a major accident. This has happened on 3 occasions total.”

NHTSA complaint #11378587, filed 2020-12, 61,000 miles

“While driving on the highway and using the hands free feature on iPhone, I said, Hey Siri, and somehow it made the automatic braking on my 2019 Infiniti Qx50 engage unexpectedly. This is not the first time it has engaged unexpectedly and there are also instances when the sensors engage without anything nearby.”

NHTSA complaint #11707903, filed 2025-12

“On three separate occasions, the collision avoidance system activated without anything blocking it. One incident I was driving at least 35 mph thru and intersection and the car suddenly halted to a complete stop jerking myself and my 6 year old forward. The vehicle behind me had to swerve to avoid rear ending me.”

NHTSA complaint #11494344, filed 2022-11

“I was driving down an empty road, no one in front of me, beside me, or behind me and the automatic braking system applied itself and slammed on brakes abruptly and beeped twice, without any prior warning or obstruction, causing the car to jolt into braking. I have contacted the dealership regarding this and they are looking at the precollision and emergency braking system next week. There were no prior warnings this braking was occurring. …”

NHTSA complaint #11567870, filed 2024-01

“The automatic braking system on my car seems to malfunction when going across the Louisiana/Mississippi bridge. As I was driving the car began to brake but it didn’t come to a complete stop. This put my safety at risk because there were cars behind me and if I would have come to a complete stop on the bridge it would have been a terrible accident. there was a warning issued on my dash while the car was beginning to brake on the bridge.”
