2019 Infiniti QX50 driver assistance problems

Filed Apr 23, 2026 · Driver assistance, Electrical · NY

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 the federal safety agency 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.

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.

On 3 different occasions while traveling over 50 mph on the highway, with no other cars around, my Qx50 automatic emergency braking initiated and stopped my car. This is a serious safety issue and I am very lucky I was not rear-ended.

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.

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.
