2022 INFINITI QX50

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.

While the vehicle was being operated under normal driving conditions, the hood unexpectedly disengaged and flew upward from the windshield side of the vehicle. This sudden and dangerous event substantially obstructed the driver's visibility and created an immediate risk of catastrophic injury, death, and property damage. Fortunately, no collision occurred; however, the potential consequences of such a failure are self-evident.

In reference to the recall R2582 and NHTSA recall 25V-437. I had made an appointment for an engine inspection for my 2022 Infiniti QX50 for August 15, 2025. I delivered my vehicle to the dealership at 7:00 am and was called by the dealership at 8:13 am and was told that they were told by Infiniti not to inspect my vehicle. They asked me to come and get it. They noted on the invoice that the recall was suspended by Infiniti on August 7,2025. No work was performed. The public notice of the suspension was for August 18, 2025.

Multiple electronic and sensor issues with the display screens and infotainment center. Time/time zone change from 12-hour format to military time off and on sometimes multiple times a day. Dash board routinely goes black and not displaying any information. HUD proximity alerts continually go off/flashing when no vehicles are around, tagging the same areas on a specific street that was empty. The sensor system engages the braking system after a faulty proximity alert or a vehicle is outside the normal range. Navigation system map blacking out Inability to disconnect Bluetooth calls using the steering wheel end button and the end button on the screen. The infotainment screen would not respond to menu button for the audio and climate control nor could you access it through the touchscreen menu. The radio would stop working randomly. I had to go to the dealership to get this corrected it would not restart on its own even if it was left overnight. The audio button also would not work. The car would not recognize the profile connected to the key fob routinely. After service, the car took over 8 minutes to lead the infotainment system. The blind spot warning would not function properly continuously. The car was taken into the dealership multiple times, it was assessed by "engineers" 3 times, and it had a total of 3 infotainment systems in this vehicle with 2 replacements since leasing the vehicle. These issues continue to remain and there seems to be nothing that Infiniti can or will do to fix these issues permanently.

This behavior is normal, and no repairs should be performed. When the AEB system performs an intentional shutdown, the customer may state the following:  The ICC stopped working while driving,  The AEB/FEB warning light is ON, or turned ON, while driving (Figure 1),  The message “Unavailable Front Radar Obstruction” or “Forward Driving Aids Temporarily Disabled Front Sensor Blocked See Owner's Manual” has displayed while driving (Figure 2). AND  DTC C1A16, C1A16-97, C2582, or C2582-97 is the ONLY DTC stored. Figure 1 Figure 2 Forward Driving Aids Temporarily Disabled Front Sensor Blocked See Owner’s Manual

TELEMATICS CONTROL UNIT RESET AFTER AUTOMATIC COLLISION NOTIFICATION SERVICE INFORMATION The Telematics Control Unit (TCU) has the ability to send an automatic collision notification when the vehicle is involved in an accident. Once an automatic collision notification is performed, the function becomes disabled and the TCU must be reset to re-enable the automatic collision notification function. Some models will store DTC B2E1B-97 for “Automatic eCAll locked” as “CURRENT” when this function is disabled. This bulletin describes how to reset the TCU after an automatic collision notification has been performed. For models with B2E1B-97 for “Automatic eCAll locked” set as “CURRENT”, complete the SERVICE PROCEDURE starting on page 2, and then erase DTCs after confirming the TCU condition is “UNLOCK”.

TELEMATICS (IVC) SERVICE INFORMATION Vehicles equipped with factory telematics system HINT:  If the client experiences Wi-Fi hotspot related concerns only, DO NOT replace the TCU. Have the client contact the AT&T Support line at 1 (888) 719-7242.  See ITB12-011 for models built before those listed above. SERVICE INFORMATION The APPLIED VEHICLES are equipped with a wireless communication device called a Telematics Communication Unit (TCU). The TCU communicates with the Infiniti Data Center to provide various security and convenience services. This bulletin contains important service procedures that must be performed properly in order to set-up and maintain the telematics system for the APPLIED VEHICLES.  An Order of Completion table has been provided on the next page that lists the steps required to successfully configure a TCU after it has been replaced.  A CHECK-OFF SHEET has been provided on page 16. Print and check off steps as they are completed. Staple the completed CHECK-OFF SHEET to the repair order.
