2021 Infiniti QX50 Complaints

On June 16, 2026, a 2021 Infiniti QX50 experienced a safety-related malfunction while being driven at approximately 15–20 mph. The vehicle suddenly jerked, lost power response, displayed multiple warning lights, showed a “System Fault – See Owner’s Manual” message, and became unresponsive/difficult to control. The engine remained on, but the vehicle did not respond properly. The vehicle struck a fixed object/rock. A police report was filed/requested, and medical evaluation was sought afterward. The suspected failed or malfunctioning systems are the engine/powertrain response, electrical system, and related control systems. The vehicle should be available for inspection upon request and should be preserved before any diagnostic codes, freeze-frame data, event data, modules, or electronic records are cleared, reset, repaired, overwritten, or destroyed. Before this incident, repeated drivability and safety-related concerns were reported to Infiniti/dealer service departments, including...

The contact owns a 2021 Infiniti QX50. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from under the hood. No warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed and metal shavings were found in the oil pan. Upon further investigation, the contact associated the failure with NHTSA Campaign Number: 25V437000 (Engine and Engine Cooling); however, the repair was denied due to the criteria not being met, a lack of maintenance records, and sludge in the oil pan. The vehicle was previously taken to a local independent mechanic to be diagnosed and there was no sludge in the oil pan from a previous maintenance service. The contact was adamant that the VIN was previously associated with the recall, but was removed. The manufacturer was made aware of the failure. The failure mileage was approximately 122,000.

There is an active and unremedied safety recall on my 2021 Infiniti QX50 (NHTSA Recall #25V-437) for a critical engine defect that can result in complete engine failure and risk of fire. The recall was issued on June 26, 2025. I am an active-duty military member stationed in Germany. I shipped my vehicle in January 2026, before a remedy was available. My vehicle is now exhibiting all the early warning signs mentioned in the recall notice, including unusual engine noises, rough performance, and illuminated warning lights. I first contacted Infiniti for assistance on March 19, 2026. As of today's date, after more than three months of communication with their representative (case #[XXX]), Infiniti has failed to provide a remedy or a timeline for the repair. They have been unable to coordinate with a local dealer in Germany, leaving me to drive a vehicle with a known, dangerous safety defect. The manufacturer is failing to provide a remedy in a timely manner as required. INFORMATION RED...

Open recall on Engine (NHTSA #25-V437) Engine has been replaced and recall repaired.

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 pre...
