2019 INFINITI QX50 Driver assistance Problems

2019 Infiniti QX50 with engine bearing failure defect matching NHTSA Recall #25V-437. Vehicle was sold to me on 12/24/2025 by a dealer, MORE THAN FIVE MONTHS after the recall was issued on 07/14/2025. The dealer NEVER disclosed the active, unrepaired safety recall. Two months after purchase, the engine developed loss of power and unusual noises - exact symptoms described in the recall. An independent mechanic diagnosed a pre-existing camshaft bearing defect. Despite component replacement, symptoms persist, confirming the defect was present at time of sale. This is a serious safety violation. The dealer knew or should have known about the recall via CARFAX and failed to disclose it, violating federal law 49 U.S.C. § 30120. The vehicle is unsafe to drive with an unrepaired engine bearing failure. Safety Risk: Engine bearing degradation can lead to complete engine failure while driving, resulting in loss of motive power and crash risk. Requested Action: Federal investigation into dealer's failure to disclose active safety recalls.

Good morning, I am writing to formally escalate a serious and unresolved safety concern involving my vehicle and to follow up on my existing case (Case #XXX). On April 22, 2026, while driving on the highway at approximately 55 mph, my vehicle suddenly performed a hard stop as if it detected an imminent collision. At the time, there were no visible obstructions or vehicles directly in front of me that would have warranted automatic emergency braking. This is a repeat issue. A nearly identical incident occurred on August 8, 2025, which was previously reported. Despite that report, the problem remains unresolved and continues to present a significant safety risk. These unexpected braking events create a hazardous driving condition with a clear risk of rear-end collision, particularly at highway speeds. Based on the pattern and circumstances, this strongly suggests a false activation of the automatic emergency braking system or a related safety system malfunction. Given the repeated nature of this issue and the potential safety implications, I am formally requesting: * Immediate escalation of this case to the appropriate engineering or safety review team * A full investigation as a potential safety defect * Identification of any related technical service bulletins, recalls, or known system issues * A clear plan and timeline for diagnosis and resolution at an authorized INFINITI dealership * Confirmation of whether reimbursement or other corrective action will be considered given the ongoing safety risk and repeated service attempts Please confirm receipt of this escalation in writing, along with next steps and assigned case handling details. I expect timely and serious attention to this matter given the safety risk involved. Sincerely, XXX XXX

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.

The contact owns a 2019 Infiniti QX50. The contact received notification of NHTSA Campaign Number: 25V437000 (ENGINE AND ENGINE COOLING). However, the part to do the recall repair was not yet available. The contact stated that while driving at an undisclosed speed, there was an abnormal knocking sound coming from the engine. Most recently, while stopped at a traffic light or stop sign, the automatic emergency braking system indicated that the vehicle in front was too close, even though the vehicle was at a safe distance. Several unknown warning lights were illuminated. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The failure mileage was unknown.

In November 2024, my 2019 Infiniti QX50 experienced a sudden and severe mechanical failure while driving. The vehicle unexpectedly lurched forward and then came to a complete stop in traffic. At that point, I was unable to shift the car into neutral or any other gear, which resulted in obstructing traffic. The vehicle was towed to a local mechanic, who diagnosed a total engine failure and quoted repair costs between $15,000 and $20,000 related to a VRC component. Recently, I became aware of a recall concerning similar engine issues affecting certain Infiniti QX50 models. However, my vehicle’s VIN is not listed among those affected by the recall. Given the severity of the failure and the potential safety risks, I would like to formally file a complaint regarding the 2019 Infiniti QX50 to ensure this issue receives proper attention. Thank you for your time and consideration.

Jul 22, 2022

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.

There is a continuous issues with my battery dying. There are multiple malfunction lights showing, particularly the rear collision light. The check engine light is also showing, and I have had an oil change recently. The car breaks on its own. While backing into a space, the steering wheel would not completely turn right until I straightened up the car. Finally. I have had my driver's side car seat repaired three times by the dealership. It works sometimes and not others. Any suggestions on any or all of this would be helpful. Thank you.

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.

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.

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.

WHILE DRIVING, THE VEHICLE WILL DECLINE IN ACCELERATION AND YOU CAN NOT INCREASE ACCELERATION. WHEN TURNING THE VEHICLE OFF, THE CAR WILL PROCEED AT A SLOW PACE. INFINITI DEALER TOLD ME THAT I NEEDED TO LET THE CAR WARM UP FOR 30 MINUTES. THE ENGINE MAKES NOISE AS IF THE VEHICLE IS IN NEUTRAL. AT TIMES, ONCE TAKING YOUR FOOT OFF THE BRAKE PEDAL TO SWITCH THE GAS, THE CAR WILL TAKE OFF FROM UNDER YOUR FOOT. WHILE DRIVING, THE CAR WILL COME TO A COMPLETE HALT AS IF IT WAS APPROACHING A COLLISION. ALL EMERGENCY INDICATORS WILL GO OFF. THE CAR MUST BE TURNED OFF TO RETURN TO DRIVING. VEHICLE HAS BEEN SERVICED BY INFINITI, WHERE DIAGNOSTICS ARE RAN BUT DOES NOT REGISTER AN ISSUE. LAST SERVICING, THE SERVICE MAN TOLD ME TO JUST CALL CONSUMER AFFAIRS, BUT CONSUMER AFFAIRS ASKED FOR A CLAIM NUMBER WHICH I DID NOT HAVE.
