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.

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.

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.

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 REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Dear NHTSA Representative, I am filing a complaint against Infiniti regarding refusal to perform a recall-related engine replacement on my vehicle. Vehicle Information: • Year: 2021 • VIN: [XXX] I brought my vehicle to Grubbs INFINITI in Grapevine, TX for recall service in August 2026 and again on February 11, 2026. The dealership refused to perform the recall-related engine replacement. The reason provided was that oil change maintenance had not been completed on time by the previous owner before I purchased the vehicle. However, since I have owned the vehicle, all oil change maintenance has been completed on time and properly maintained. The engine has not failed, but it remains subject to the recall and the associated safety risk. I believe denying recall service based on maintenance history from a prior owner is improper and leaves me operating a vehicle that is subject to an unresolved safety recall. I respectfully request that this matter be investigated and that Infiniti be required to comply with its recall obligations and perform the required repair at no cost. Please let me know if additional documentation is needed. I can provide maintenance records and service documentation. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. The engine is the system that is malfunctioning. There was a recall on my vehicle. I was told to bring the vehicle in for the metal found in oil. Infiniti denied to replace my engine which was stated during the recall that the engine would be replaced. My vehicle was returned to me without receiving an engine per the recall. 2. My safety is at risk because the engine can fail which can cause me to lose controls of the vehicle and not be able to prevent an accident. That also places others at risk. My engine could also blow up at any given time. 3.The problem has been confirmed by the Infiniti dealership (service department) during both inspections. 4.The vehicle has been inspected by the manufacturer. Infiniti had denied to expect responsibility per the recall and denied to replace my engine per their recall. 5.There had not been any warnings, messages or symptoms of the problem prior to getting notification of the recall or getting my vehicle inspected per the recall. This is the second complaint that I am filing against Infiniti per the recall that was called on my vehicle. My vehicle has not been serviced correctly and my engine has not been replaced.

My 2021 Infiniti QX50 is subject to Recall 25V437000 for engine bearing defects that can cause engine failure, loss of power, and fire. During the recall inspection, Cerritos Infiniti found metal debris. They first diagnosed this debris as being in the engine oil and recommended immediate engine replacement. Days later, they reversed this diagnosis, claiming the debris was only on the removed oil pan from "technician scraping" and that the engine is safe. Infiniti Corporate reviewed the dealer's evidence, denied the warranty claim for an engine replacement, and refuses to provide me with any technical documentation—photographs, video, or analysis—that would verify which diagnosis is correct. They have refused my request for an independent inspection by a Field Technical Representative at a different dealership. The dealer has now threatened $60/day storage fees to coerce me into accepting the vehicle back without any verifiable proof of engine safety. I am being forced to choose between paying punitive fees or driving an unverified vehicle with known, documented risks of catastrophic failure and fire. I am filing this complaint not to seek an engine replacement, but to request that NHTSA investigate whether Cerritos Infiniti and Infiniti Corporate have violated federal safety recall requirements by: 1. Failing to provide owners with complete and accurate information about the results of recall inspections; 2. Destroying evidence (the original contaminated oil/filter) before an independent review could occur; 3. Coercing owners into accepting potentially unsafe vehicles through punitive storage fees; 4. Failing to perform the required recall remedy—which, if "specific debris" is found, requires engine replacement—and instead substituting an unverified, undocumented "second oil change" as an informal remedy.

I proactively brought my Infiniti QX50 to the dealership for inspection due to the recall. The service department found metal in the engine, which they stated is related to a known recall issue. The service department told me that I need an engine replacement, but Infiniti has denied engine replacement despite this finding. According to the recall, metal inside the engine presents a risk of sudden engine failure, including loss of power while driving, which increases the risk of a crash. The recall exists to prevent this exact outcome, yet the manufacturer is refusing the recommended remedy. I am concerned about vehicle safety and believe this condition should qualify for engine replacement under the recall.

Vehicle: 2021 Infiniti QX50 VIN: [XXX] Mileage at second failure: 154,282 miles I am reporting a repeat engine failure involving bearing material consistent with a known Infiniti VC-Turbo engine defect. The original engine in my 2021 Infiniti QX50 failed and was replaced with a brand-new long block in May 2024 at approximately 85,700 miles. I paid for this engine replacement out of pocket because the recall had not yet been issued. After the engine replacement, the vehicle was regularly maintained with full synthetic oil at reasonable intervals. There was no sludge present in oil, upon inspection. After receiving notice of Infiniti recall R25B2, I contacted the authorized Infiniti dealer (Ed Hicks Infiniti) to request an inspection and was advised to wait because the recall was temporarily on hold. As a precaution, I had another dealership inspect the oil and oil pan on August 18, 2025, and no debris or abnormalities were found at that time. On [XXX], the vehicle experienced engine failure symptoms and was towed to Ed Hicks Infiniti. The dealer inspected the engine and confirmed bearing material present in the oil pan with no sludge. This is the same failure mode described in the recall. Infiniti denied recall coverage and goodwill assistance solely due to total vehicle mileage, despite the fact that: • The failed engine was a replacement engine installed before the recall • The failure occurred well before a reasonable engine lifespan • The failure mode matches the recall defect • There was no evidence of neglect or sludge I am reporting this to document a repeat engine failure related to a known defect and to request regulatory review, as consumers who paid for engine replacements prior to the recall appear to be excluded despite experiencing the same safety-related failure.

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.

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.
