Complete sudden engine failure , motor lost acceleration. It started with engine knocking then full and complete engine failure. Oil light illuminated when engine failed. I did check the engine and oil was full on a cold engine and the vehicle is properly maintained as it is a leased infiniti vehicle. Please note there have been two previous engine light incidents. First I was told it was a speaker in the rear door, second I was informed it was an evaporation seal. Lastly was this very intense engine shut down. I have research and found that there are issues with the turbo bearing with my particular engine and turbo. Engine 2.OL 4 cylinder ( KR20DDET)

Defect investigations
Complete loss of motive power due to engine failure
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 ODIâs 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 vehicleâs 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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to

What 2023 Infiniti QX55 owners say
Most recent owner complaints, unedited.
Every single one of these 2.0 litre engines should be recalled. My partner has a 2022 QX50 and the long engine should be replaced. On May 18, 2025, my QX55 with 16,500 miles that I was absolutely perfect in servicing suddenly started losing power, grinding, then the oil light came on, followed by the check engine light. Suddenly, it was undrivable in traffic. I was stuck in front of entrance to a hospital in the most inconvenient and dangerous place. It wouldn't start, and when it did, the grinding noise was incredibly loud. I was stranded and it was flatbed towed to Fort Wayne (Indiana) Infiniti, and the following diagnosis was yielded: CONNECTING ROD BEARING FAILURE FROM CYLINDER 4 - CONTAMINATED OIL CONTROL SYSTEM. INTERNAL FAILURE OF CONNECTING ROD BEARING. TURBOCHARGER OIL FEED LINE HAS METAL PIECES IN TURBOCHARGER. REPLACEMENT OF LONG ENGINE AND TURBOCHARGER ASSEMBLY REQUIRED. Nissan is trying to get away with recalling just a few of these. It is a design flaw; not an issue with a specific production period.
Bluetooth and CarPlay connection suddenly disconnects from my iPhone while driving, usually after 5-10 minutes after establishing a normal connection. This only affects the use of the phone component and not the other elements of the connect (map/navigation, music are not affected). This is dangerous because I am often on a freeway and engaged in a business call, and I must rapidly either switch to using my handset or change to “speaker” mode on the phone in mid-call while driving. This has happened every time I have used this vehicle over the past two years, and I have taken it to the dealer (which is an excellent dealer (Sewell) that has an otherwise perfect service record. I am convinced Sewell has done nothing wrong. This has also happened on several other Infiniti models with my prior iPhones (different models with earlier versions of OS). I have been told in years past by Infiniti service corporate representatives in the past that there is an incompatibility between Infiniti and Apple phones. I was always told that the problem was solved on the next model vehicle.
