2019 Infiniti QX50: false forward collision warnings

Filed Jan 25, 2024 · Driver assistance, Electrical · FL

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. The car has had multiple issues since purchasing including headlight blinking and replacement within the first month of ownership, automatic sunroof needing a replacement because it was installed in the factory wrong, and the door lock actuator not locking/ or unlocking upon clicking lock/unlock. The car has been in and out of the Infiniti dealership in the 4 months since purchase. The car was purchased September 2023, and it is now January 25th, 2024.

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.

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!

On may 4, 2019, I tool delivery of a new infinity, qx50 and after 2.5 months of ownership (july 26, 2019 to present), I'm having ongoing / unresolved problems / failures with; audio, lane departure, collision warning w/ sudden stopping, heated / cool seats, infotainment, audio, tailgate, remote door locks, both screens going blank, phone / bluetooth connection, awd, automatic shifting problems and extremely soft brakes that put me thru 2 controlled intersections. The dcu has been replaced 4 times and I still have the same ongoing / unresolved problems. I told the service manager (rudy), to start replacing all the sensors, cms and camera and he refused to do that. My qx50 has been in for service five times (including today, 04-21-2021), for a total of 6+ weeks. The mechanic at infinity, can't replicate any of my ongoing problems / unresolved problems and I have 25 videos, showing what the qx50 is dong and infinity can't fix it. I pay a lot of money for the qx50 and for all the driver safety features, other amenities and it still continues to fail miserably and does not perform as intended. Because of these unresolved problems and ongoing issues, my wife refuses to drive in the qx50 with me. I have asked infinity to buy back the qx50 and they flat out refused. I had to obtain a lawyer.

Two separate incidents of vehicle performing preemptive braking with no other vehicles or objects present while the vehicle was in motion. The first incident occurred while traveling at speeds approximately between 45-50 MPH through a four-way intersection; no vehicles were present. The second incident occurred while driving at a speed that was approximately between 30-45 MPH approaching an intersection. Probable cause: front crash prevention, forward emergency braking with pedestrian detection, predictive forward collision warning. The vehicle was checked in for service and after a seven day period, no faults were found. The dealership could not replicate the condition stated above.

The forward emergency breaking(feb) with pedestrian detection and predictive forward collision warning(pfcw) did not activate when I was starting up from a 4 way stop sign intersection on a city street. My 2019 qx50 was in motion when it crashed into another vehicle on the passenger door and wheel well. Airbags did not deploy as the qx50 was , I estimate, traveling <15 MPH. Damage to the 2019 qx50 was apprx $9k. I will share auto body itemized repair parts once the qx50 is returned to me. Due to the qx50 being a 2019 not all parts are available in the infiniti inventory. Repair shop working w/infiniti dealership to work on a solution. The 2019 qx50 was moving so slow that there was no damage to the suspension as a wheel alignment is not necessary.
