A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

Recalls on the 2019 Infiniti Q50
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Risk: The lack of an image in the back-up camera display increases the risk of a crash.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 2019459126,195 units in Canada
Visual System
Issue: On certain vehicles, the rear view camera system does not return to the default setting when the transmission is shifted to reverse. This could cause a reduction in rear visibility if a driver had previously adjusted the camera display. Canadian regulations require that the rear view image returns to its original setting each time the camera is turned on. Safety Risk: Reduced rear visibility could increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a dealer to update the software for the rear view camera.
Reports where the owner recorded a crash, a fire, an injury or a death.

Air bags failed. Auto has 28,000 miles and has no accidents. Warning light showed that airbags were not working June 2026. Auto brought to dealer, and it is a very costly job to fix. Auto just out of warranty in years not miles. Infiniti in previous years has had a recall on their cars, but not my VIN number for failing airbags. This is a manufacturing defect, and it should not have to cost me. Infiniti has offered a partial discount.

ENGINE
own a 2019 Infiniti Q50 3.0t Sport with approximately 80,000 miles. The vehicle began experiencing engine knocking/ticking noises, rough idle, hesitation under acceleration, shaking, and intermittent misfire symptoms. The issue continued even after replacing spark plugs and ignition components. The dealership/mechanic reported possible internal engine damage and metal shavings in the oil, indicating potential failure of internal engine components. The vehicle has been regularly maintained with oil changes completed on schedule. This appears to be a widespread issue affecting many Infiniti and Nissan vehicles equipped with the VR30 3.0 twin-turbo engine. Numerous owners online report similar symptoms including engine knocking, turbo failure, metal contamination, loss of power, and premature engine failure at relatively low mileage. The issue creates a serious safety concern because the vehicle can lose power, hesitate during acceleration, or potentially fail while driving in traffic or on highways. I am requesting that NHTSA investigate repeated engine failures involving the VR30 engine platform used in Infiniti Q50/Q60 and related vehicles.”

POWER TRAIN
While operating the vehicle under normal driving conditions, the engine experienced a significant loss of power and reduced acceleration. The issue is believed to be related to turbocharger failure within the engine system. The loss of power created a safety concern, particularly when attempting to merge into traffic and maintain highway speeds. The vehicle did not respond as expected when acceleration was needed, which could increase the risk of an accident in certain driving situations. The problem has been confirmed by a dealership service department, and the vehicle is currently available for inspection. The diagnosis indicates that the turbochargers require replacement. Prior to the failure, there were limited warning signs. Any warning indicators were either minimal or appeared shortly before the issue became noticeable. The failure occurred at approximately 107,000 miles. Based on publicly available information, similar failures have been reported on this vehicle model, suggesting a possible pattern related to the turbocharger system.

The twin turbo failure is a known issue with Infiniti. I took my vehicle to the dealership and it was diagnosed with having a passenger side turbo failure. I have 145K miles on my vehicle. It is outside of the warranty period and very expensive to repair. Infiniti knows there is a problem regarding turbo failure in the Infiniti Q50 and the consumer is forced to deal with expensive repairs $7K for one turbo per the dealership. Had I been made aware of there being a problem, I would not have purchased an Infiniti.

Shortly after purchasing the vehicle, I began experiencing serious performance issues. While driving, the vehicle suddenly lost power, would not accelerate properly, and warning lights appeared on the dashboard. The vehicle eventually shut off while in operation. The vehicle was inspected by a dealership, which initially stated there were no issues. However, the problem continued and worsened. The vehicle was then inspected by an authorized Infiniti dealership, where technicians identified a consistent knocking noise coming from the engine. The dealership indicated that the noise is consistent with internal engine damage and recommended further inspection and likely engine replacement. The issue developed very shortly after purchase, and there were no prior indications that the vehicle had been damaged or misused. The sudden loss of power and engine failure created a potential safety hazard, especially while driving in traffic, as the vehicle was unable to accelerate and could have led to a dangerous situation. The vehicle is currently available for inspection, and the issue has been confirmed by a certified dealership. The cause of the failure is currently under further evaluation.

While driving, my vehicle suddenly shut off without warning. After restarting, the vehicle would not accelerate over 40 miles per hour. I had the vehicle inspected by the dealership, and they informed me that the engine oil filter contained metal debris. The dealership explained that the presence of metallic particles in the filter could indicate internal engine wear or damage, and they recommended a full engine replacement at a cost of approximately $20,000. At this time, I have not been shown the filter or the debris, but I was advised that this condition may require further diagnosis and possible engine repair or replacement.
