On August 1, 2025, at 44,391 miles on the Vehicle odometer, Plaintiff experienced a catastrophic failure of the complete power-steering and rack and pinion system, while traveling on Vermont Interstate 89 in Middlesex, Vermont. The steering wheel instantly became largely immoveable, the car shuddered and vibrated. By sheer luck, Plaintiff’s Vehicle did not collide with another vehicle or object. The Plaintiff could have been seriously injured or killed, had a collision resulted from the loss of steering ability. Plaintiff navigated to a nearby park and ride pull-off; the vehicle was completely incapacitated. An inspection of the Vehicle by Infiniti of Nashua Service Department revealed that the complete power steering rack and pinion system had failed. Service records research by Infiniti of Nashua Service Department revealed that at 31,000 miles on the Vehicle odometer, the power steering and rack and pinion system had a previous complete failure and was replaced under Warranty. The Service Department advised that failure of a system at 31,000 miles, let alone again at 44,391 miles, indicated a factory defect or an improper installation/repair of the system on the part of Infiniti. INFINITI OF WARWICK RHODE ISLAND DID NOT DISCLOSE THE COMPLETE SYSTEM FAILURE at the time of the 31,000-mile replacement, and falsely reported to CarFax “steering/suspension checked,” instead. Litigation pending.

I was driving at the intersection of South I-55 and I-355 on the left most lane at 70 mph. All of a sudden, my car started knocking and since there was no shoulder to the left I had to move to the right by managing to get through multiple lanes to get to shoulder safely. Given the issue with engine, it would not accelerate so I had to safely decelerate and come to a stop. I called the towing company and they towed my car to the dealership. This car had a recall when the dealer contacted me and I had them take a look at 98K miles and they stated everything was fine. Following few weeks later, the engine completely gave out. The dealer is working with manufacturer to get the engine replaced. However, he is not sure who will pick up cost for replacing turbo. Turbo is part of the engine and should also be replaced under the recall. Needless to say, this was a dangerous situation and I am glad the situation had a safe outcome.

25V437000 · Engine And Engine Cooling:engine:hard Parts Internal/mechanical

Jun 27, 2025

Nissan North America, Inc. (Nissan) is recalling certain 2021-2024 Rogue, 2019-2020 Altima, 2019-2022 Infiniti QX50, and 2022 Infiniti QX55 vehicles equipped with 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines. The engine bearings may have manufacturing defects that can lead to engine failure.

Consequence & remedy

Consequence: Engine failure increases the risk of a crash. A bearing failure may cause a breach in the engine block, allowing hot oil to be discharged, increasing the risk of an engine fire.

Remedy: Dealers will reprogram the engine control module (ECM) software, free of charge. Owner letters were mailed April 8, 2026. Owners may contact Nissan's customer service at 800-647-7261 or Infiniti's customer service at 1-800-662-6200. Nissan's numbers for this recall are R25A8/A9 and R25B1/B2.

19V654000 · Back Over Prevention: Sensing System: Camera

Sep 12, 2019

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."

Consequence & remedy

Consequence: The lack of an image in the back-up camera display increases the risk of a crash.

Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.

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.
