I am a [XXX] woman who purchased my first vehicle on December 6, 2024, with 43,000 miles. I have driven fewer than 20,000 miles since purchase, and the vehicle currently has approximately 62,000 miles. Until January 19, 2026, I experienced no issues. I have properly maintained the vehicle and followed all recommended service guidelines. I completed three oil changes during my ownership, averaging approximately every 8,500 miles. Two oil changes were performed by a licensed mechanic, and the most recent oil change and inspection were completed on November 29, 2025 at Legend Infiniti. I have receipts for all services. On January 19, 2026, while driving approximately 65 mph on a four-lane highway in Long Island, the vehicle suddenly went into limp mode and dropped to about 10 mph without warning. This created an extremely dangerous situation with a serious risk of collision. I first brought the vehicle to my mechanic, who advised me to take it to an authorized Infiniti dealership due to an engine bearing recall associated with my VIN. I brought it to the same Infiniti dealership that had serviced it two months earlier. After diagnosis, the dealership stated there was engine sludge and that I needed a new engine. They denied any connection to the recall and attributed the issue to poor maintenance. However, two months prior they completed an oil change and inspection with no documentation of sludge, engine concerns, or maintenance deficiencies. I was not informed of any recall at that time. My warranty claim was denied on the basis that sludge is not covered and that maintenance performed outside Infiniti could not be validated, despite providing receipts from licensed facilities. I am also being told there are record-access issues because the vehicle was originally sold in Canada. Given the sudden loss of power at highway speed and the known recall related to engine components, I believe this presents a significant safety concern and warrants investigation.

My vehicle is affected by Recall 25V437. I am already experiencing recall-related symptoms, including stuttering, unusual engine noises, and uneven acceleration. I leased the vehicle through DFW Auto and Services INC, On August 15, 2025, at 9:35 AM, I spoke with Sam in the finance department of DFW Auto and Services INC during a 3‑minute call from 214‑205‑7327. I specifically asked about the recall affecting this vehicle. Sam stated that the recall had been “taken care of.” This was false, as Recall 25V437 remains open and unresolved. The dealership misrepresented the recall status of my vehicle, failed to disclose that Recall 25V437 remained open, and delivered a defective product – a vehicle with a known safety defect that directly impacts usability, value, and consumer safety. On November 18, 2025, I submitted a formal complaint to the Attorney General regarding this matter. This misrepresentation placed me at risk of driving a vehicle with a known safety defect that could result in sudden engine failure or fire. I am requesting NHTSA to investigate the dealer’s misrepresentation and ensure proper enforcement of Recall 25V437. This recall must be remedied at no cost to me. I have contacted: Crest Infiniti 6100 State Highway 121, Frisco, TX 75034 to have Recall 25V437 remedied. I am currently still waiting response from the service center for an appointment to have the engine replaced.

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.
