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 vibration during acceleration, abnormal gas pedal vibration, lack of acceleration, poor power response, jerking/jolting, rough ride, abnormal noises, front-end noise, and safety/reliability concerns. Some concerns were documented in service records. Prior repairs included front passenger-side wheel bearing replacement and cooling fan/IPDM-related warranty work, but the drivability/power-response concerns continued. UNKNOWN whether the manufacturer completed a full post-incident inspection. The vehicle has been reviewed by police and insurance-related parties to the extent related to the collision. This complaint is being filed because the condition appears to involve a safety defect causing loss of power response and system fault warnings while driving. I am currently waiting on the police report, the report number has been provided.

Without any warning or indicator light on the dash, the vehicle lost power when pulling out of our driveway - we live on a main road and were very lucky not to be hit by upcoming traffic. The car went into limp mode and would not accelerate past 20mph. We have been fighting with Infiniti for the last three weeks as no one can find the problem and they finally said a new engine was needed. There is on 35,000 miles on this car and we had to fight to have this replacement covered under warranty. Now that parts are back ordered and we are not receiving any help. We are three weeks without a vehicle and have no loaner vehicle. No one at Infiniti can give a timeframe for the resolution of this issue, what caused this issue and we are now very fearful that this will happen again - even with an engine replacement. This was very scary for our family and we are amazed that there was no indicator light or warning. The car didn't make any noises and was running great and then all of a sudden it would not go. Very alarming to say the least!

This vehicle is equipped with a push button to start and stop the vehicle engine. The button is mounted horizontally next to the gear selector switch near the driver. Twice now, while traveling at highway speeds, the vehicle engine has stopped when my dog taps on the switch. I usually secure my dog while traveling with him, but there are occasions when his seat belt needs to be released, usually due to him getting tangled up. If you own a dog than you know that he will tend to want to climb on top of you as soon as he is released from his leash, so putting the button in that position represents a pretty significant safety issue for me. I have called and reported this to Infiniti, and the agent told me I needed to fashion some sort of cover for the button, and ask my dealer if there is a software solution.

PE23023 · Complete Loss Of Motive Power Due To Engine Failure

Opened Dec 13, 2023 · Closed Jul 18, 2025

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling; Engine And Engine Cooling:engine:hard Parts Internal/mechanical

On December 13, 2023, the Office of Defects Investigation (ODI) opened PE23-023 to investigate allegations of engine failures leading to loss of motive power in model year (MY) 2021-2023 Nissan Rogue; MY 2019-2021 Nissan Altima; and MY 2019-2021 Infiniti QX50 vehicles. At that time, ODI had received 6 Vehicle Owner Questionnaires (VOQ) and multiple early warning reports, with consumers reporting engine knocking noises accompanied by a loss of engine power while driving. The investigation identified bearing failures in certain vehicles equipped with the subject 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. ODI also identified early warning reports describing thermal incidents that occurred immediately after the vehicle suffered a catastrophic engine failure.  The failures were the result of a manufacturing defect in specific engine bearings (main, A-, C-, and L-link) or other engine components that may cause engine damage and potentially lead to engine failure. Engine failure can result in a loss of motive power event that can increase the risk of a crash.  Engine failure might also result in a fire if internal components detach and impact the engine block creating a hole that allows engine oil to reach hot surfaces. In its April 2024, May 2024, and June 2025 responses to ODI’s information requests, Nissan provided 998 customer reports (including complaints, field reports, and legal claims) and 1,107 warranty claims related to the alleged defect.  When combining ODI and manufacturer report data, there are 1,878 unique VINs that have experienced failures across all subject vehicles.  In one of the early warning reports, ODI identified an incident involving a 2022 Infiniti QX55 that resulted in an engine fire following an alleged engine failure. The 2022 Infiniti QX55 was not included in the scope of this investigation but the vehicle model shares the same 4-cylinder 2.0L variable compression turbo engine.  Based on the information included with the early warning report, the fire can be directly related to the alleged defect.   A further review of ODI and manufacturer data, identified 12 allegations of engine compartment fires in subject vehicles; three were confirmed as directly related to the engine failure, and nine reports described an under-hood fire that occurred following a loss of power event. Additionally, ODI identified multiple reports describing an engine block crack or hole surrounded by oil residue following an engine failure. On June 27, 2025, Nissan submitted recall 25V-437 involving 443,899 MY 2021-2023 Nissan Rogue, MY 2019-2021 Nissan Altima; MY 2019-2021 Infiniti QX50; and 2022 Infiniti QX55 vehicles. The recall remedy provides the dealer instructions to inspect the engine oil pan for the presence of specific metal debris. For customers with the 3-cylinder 1.5L VC-Turbo engine, if no debris is detected during the inspection, dealers will replace the oil pan gasket, engine oil, and reprogram the vehicle’s Engine Control Module (ECM). For customers with the 4-cylinder 2.0L VC-Turbo engine, if no debris is detected, dealers will replace the engine oil. In the case where specific debris is detected and confirmed by Nissan Powertrain Call Center, dealers will be instructed to replace the engine. In addition, Nissan will extend the vehicle warranty to 10 years and 120,000 miles for the recall subject vehicle population after the dealer performs the inspection. Nissan has implemented multiple corrective actions to address the identified manufacturing defects of certain engine block internal components.  In view of the recall action (25V437) taken by Nissan, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.
