I was driving around 30 mph crossing an intersection when the Emergency Braking system activated and caused the truck to stop. There was nothing obstructing the vehicle, nor were any pedestrians near. This is the 3rd occurence when this happened.
2019 Infiniti QX50 driver assistance complaints
Page 2 of 2: complaints 11 to 18 of 18, newest first, as owners wrote them.
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!
Multiple repeated problems with electrical system. Repeated crash sensor failure. This mainly happens when it is warm or sunny. The dealership has had the vehicle four times and the problem is still reoccurring. The malfunction light comes on when the car is first started or while driving. The dealership stated that none of the crash sensors work when it is lit. They have replaced the module that was diagnosed to be the problem, however there is still the same issues. They are going to replace the module again. They have replaced a module to control the wipers twice. The wipers still come on randomly when it is sunny, and the delay for the wipers does not work when it is raining. The cruise control stopped working and is throwing codes. This morning`s new warning was shift system malfunction. It's been in three times for the air-conditioner. The cooling fan was stuck on high speed until they replaced a sensor. The car was inspected and the brake pads were okay, however when the car stopped, there was a very loud pulsation. The dealership told me it needed rear brakes, which we replaced, and $600 later, they were still pulsating. After the second time taking it back, the dealer then said it was the tires which were new. We took it to a private garage, and the problem was warped, factory front rotars because they could not support the weight of the car. They were replaced with performance drilled and slotted rotars, which corrected the issue. The dealership cannot figure out the electrical issues, so they keep replacing the same parts and returning it back in a dangerous state. Since the vehicle is throwing so many codes and has so many malfunctions that I feel unsafe driving it. All of these problems problems started December 2019, when the car had 8000 miles on it. It has been to two different infiniti dealerships, neither being able to fix it. We have photos of all the codes, but when we tried to upload, it failed over and over.
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.
Dating back to november 2019, my vehicle's automatic emergency braking have engaged 3 times without reasonable cause at speeds that vary from 40-70 MPH. The first two incidents were on normal city roads going approximately 40-45 MPH. The last incident (june 2020) happened while driving on a highway, with no traffic around, going ~70 MPH and my vehicle almost came to a complete stop. The first time I took the vehicle into the dealership, they reset the system. The most recent time they said the incident happened twice to technician and their assumption was the vehicle was not clean enough. I followed up with infiniti consumer affairs and they told me these incidents have happened in other vehicles but do not think the situations are related. With the incident now happening a total of 5 times (and when the vehicle was clean), I do not feel safe in the vehicle and believe there is an underlying issue.
