There are 6 owner-reported driver assist & adas complaints for the 2019 Infiniti QX50in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
Multiple instances of forward emergency braking system engaging on an empty road or when no vehicle is in close proximity. Dealer service department states insects on radar system may be to blame, and were unable to reproduce the issue. Warning light and brakes engage, depressing the brake pedal and returning to accelerator cancel the warning however sudden braking at highway speeds presents an unsafe condition to drivers following behind who may not anticipate sudden braking in free-flowing traffic.
Forward Collision Avoidance system automatically applies brakes during normal driving situtations. This will increase the safety risk for passangers including small children, animals, the driver and other drivers and their passangers. The warning lights came on the same time the FCA applied brakes. Numerious complaints already registered suggest approved recall and repairs are required. The QX50 is overloaded with Sensory Packages, advanced technology and is being serviced by undertrained technicians as stated in previous complaints of insufficiant maintenance repairs fixing the safety issue. If we had been in an airplane instead of a car we wouldn't be here to file this notice!
Was driving down the street going 55mph, not one car in front of me. The automatic breaking turns on and the car hit the brakes by itself. There was a car behind me during the first incident and it almost caused an accident. The driver thought I was brake-checking him and it caused him to have a fit of road rage. This particular incident has happened a total of 6 times. I took the car to Infiniti after the 2nd occurrence and they told me they couldn't find any issues with the vehicle.
After multiple related incidents, I am compelled to make a report. My car just displayed red and white flashing indicators on the dash and automatically screeched to a halt, completely out of my control, in the middle of a busy intersection. Because the road was damp from rain, my car actually skidded. I was not going to hit anything, there was no car or object in front of me. I was driving at about 30 MPH. This has happened repeatedly in parking garages and other low-light scenarios. I have brought the car to the dealer and gotten no answers. At this point I am terrified to drive the car.
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.
