My 2021 Infiniti QX50 has suffered a catastrophic internal engine failure. This vehicle is explicitly covered under active federal safety recall NHTSA Campaign 25V437000 (Infiniti Campaign R25A8/A9 / R25B1/B2) for defective, failing main and link bearings. The Infiniti dealership is actively refusing to honor the mandated federal recall remedy. The service department is attempting to illegally bypass the safety recall mandate by blaming the presence of engine sludge and claiming they do not visually see metal shavings. They are demanding that I pay out-of-pocket for a consumer-pay engine replacement. Under federal law, a manufacturer cannot deny a safety recall remedy based on vehicle maintenance history or engine sludge. Furthermore, the massive friction and overheating caused by the defective, failing recalled factory bearings directly causes and accelerates oil breakdown and sludge. The dealership is using the presence of sludge to mask a federal safety defect.

The vehicle has experienced ongoing electrical and safety-system related malfunctions shortly after being purchased as an INFINITI Certified Pre-Owned vehicle in April 2025. The issues initially included flickering interior and exterior lights, intermittent door lock malfunctions, and other electrical irregularities. In June 2025, I received notification through the INFINITI app regarding a major engine recall involving engine bearing failure concerns affecting my vehicle. I brought the vehicle to Harte INFINITI for inspection regarding the recall and my electrical concerns. During that visit, dealership personnel acknowledged there were multiple vehicles experiencing similar engine bearing issues related to the recall. Despite my concerns, I was told the vehicle was “safe to drive” because no diagnostic codes were present at that time. The problems continued to worsen over time. On February 26, 2026, during a routine oil change shortly after expiration of the basic warranty, I was presented with approximately $2,600 in recommended repairs despite previously being told there were no issues with the vehicle. Most recently, the vehicle developed Forward Emergency Braking (FEB) malfunction warnings and Lane Assist malfunction warnings involving critical driver assistance and collision-avoidance systems. These warnings raised serious concerns regarding the safe operation of the vehicle because they involve systems designed to help prevent collisions and maintain vehicle control. I was concerned that these systems could fail unexpectedly while driving, potentially increasing the risk of an accident or injury to myself, passengers, or others on the roadway. The vehicle was returned to the dealership for inspection, where I was presented with an additional repair estimate exceeding $4,600 along with diagnostic charges. Despite the active safety-system malfunction warnings, I was again advised that the vehicle was safe to drive.

The front driver-side door on my 2021 Infiniti QX50 appears to have a faulty latch, hinge, or door ajar sensor issue. The vehicle repeatedly displays a “door open/door ajar” warning even when the door is fully shut and latched. The warning can sometimes be triggered or worsened by leaning on the door or applying light pressure, which suggests movement in the latch or hinge assembly. The issue also occurs while making left turns, where the warning activates as if gravity or vehicle movement is pulling the door slightly outward. This raises concern that the door latch may not be fully securing the door during normal driving conditions. This creates a safety concern because the vehicle may not properly recognize the door as securely closed while driving. There is concern that the latch assembly may not be functioning correctly or could fail unexpectedly. The issue also creates distraction while driving due to warning messages and alerts appearing intermittently. There were warning messages prior to the issue becoming more noticeable, specifically repeated “door open” alerts despite the door appearing fully closed. The issue appears consistent with reports involving faulty or misaligned door latch assemblies and/or door ajar switch malfunctions on Infiniti QX50 vehicles. At this time, the vehicle has not yet been fully repaired or confirmed by a dealer. The problem can be reproduced intermittently by closing the door normally and applying slight pressure or leaning against the door from inside or outside the vehicle, as well as during left-hand turns while driving.

there was a problem with safety recall a week after I took the vehicle test! I went to the dealer in Las Vegas many times, but they didn't find the mistake, they told me that the car was in order! There are no warning lights on the dashboard! Everything seems fine, but I don't know why he still writes it safety recall, don't clear this and why no one can clear this and help me!
