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

Got the car from kingdom Chevy on 66 and western on February 2024 used at 62.000. I took the car back twice because the screen in the car kept cutting off fading on and fading off. Secondly, the Bluetooth plug would not work. I did not have the car a month. They kept telling me that nothing was wrong with the vehicle. I took my vehicle to the dealer and was told that there were no recalls on the vehicle and that basically my car was one of the cars that got put in the bad batch. I was also told that the only recall on this car was the hood. No one could open the hood, even if I pull the latch in the car. I explained to the guy at the Nissan dealer again that the board kept cutting on and off and all he said was it was the Bluetooth. Today my car does not start without me getting a jump. Lastly, I’ve been stopped by the cops three times on my way from work at night because the lights are auto and they they do not work properly. I really do not know what to do at this point. I called last week to speak to someone and I spoke to someone named David, who was not at all trying to help me, but was trying to sell me a car😡. He informed me that since it wasa used vehicle, the warranty has already iexpired. More importantly they are no longer kingdom Chevy. It is now under new ownership, and that they do not have access to the Records. I ended up with this vehicle because the vehicle that they recently leased to me. The engine went out once I got my oil changed at Valvoline.
When I make a turn, I hear a clicking noise and also when I come to a complete stop, I can a sound that sounds like a grunting noise. I had new brakes, rotors and brand new tires put on in 2025. I think my ball joints and tie rod is defective. I have a triple AAA membership and I just renewed it in June and it said that my 2021 has two recalls. the federal safety agency # 23V628000 The back over prevention sensing system camera & the federal safety agency# 21V138000 Steering Linkage Tie Rod Assembly.
My car is supposed to have an automatic braking system/collision detection. Two cars in front of me slammed on their brakes and the car in front of me slammed on his brake, and I didn't have enough time to react. I totalled my car, but my car is supposed to have a safety feature that automatically brakes. The faulty automatic braking didn't engage as it should have.
Door lock actuators have failed completely on 2 doors, and intermittently on 1 door of a 2021 Nissan Altima. They do not respond to either the key fob or door button. There are no warnings or indicators associated with this component so it is unknown when the failures first occurred, but it was first noticed in summer of 2025. The components have not been inspected but could be made available for inspection if requested. Not being able to unlock doors could present an entrapment hazard in the event of a collision. The doors remaining unlocked is a safety concern as there is nothing preventing the door from potentially being opened while driving, and a security concern as the vehicle may inadvertently be left unlocked even if the lock buttons are pressed on the key fob and/or door. Numerous official and anecdotal consumer reports exist but at the time of this submittal the manufacturer has not issued any notices or recalls regarding this problem.
Rear door locks both do not work other than manually locking. Reported incidents online show many others have had newer Nissan vehicles like our 2021 Nissan Altima with the same issue, some have been locked in the car and had to climb out the window and others said the door unlocked and opened while driving. This is a big concern for me as a mom who has a son driving this car, the entire reason was that the safety ratings were good on this AWD full size 2021 vehicle. We bought it certified pre-owned from the Nissan dealership 2 years ago (2024) and after 1 year, both locks stopped working unless locked manually. The actuators should now have stopped working with a car only 4 years old at the time. Now is it 5 years old, still very new, and the safety issues I've read others have had is very concerning. There was a previous recall on earlier Nissan models, and I wish Nissan would recall these newer models too since you see class action lawsuits and much concern online about the many people having this issue.
I purchased this car in April 2023 and in December 2023. I had to get a new battery when I purchased a car. They told me that there was no worries or mishaps with the vehicle they said just only normal wear and tear for is a used vehicle. My car is a 2021 Nissan Altima so the car would’ve been about two years old maybe or on his way to be in two years old when I got the car according to the Carfax and the information provided to me it only had one owner previously. I’m not sure what the person did with the car but the battery was bad fast-forward to 2025. I was hit by a F150 truck. I got T-bone I had to go to the hospital, etc. it was a pretty bad hit. My windows were cracked or excuse me broken and my airbags were not deployed. No airbag was deployed. I did have my seatbelt on when the police came. My CB was still on so my car had to go. It was towed, and then it went to a mechanic shop to be fixed by the other person‘s insurance at that time, the mechanic sent me photos and explain that there was faulty, wiring and seatbelts, and he was unsure why it would be there. He said it was a immediate safety hazard, and I should address it with North Coast as soon as possible North Coast auto Mall is where I purchased the car from when I reached out to them all they told me was all you’ve had the car for about three years now we don’t know what you may have done to the Car. I still have the photos of the faulty wiring. I’m no mechanic. I explained to them that was an accident and the airbags did not deploy and when the mechanic also confirmed that’s probably why I have not heard anything from North Coast. This is an extreme safety hazard.
While heading west on interstate after a Drs. Appointment my wife was driving our 2021 Nissan Altima when suddenly there was a loss of power to the engine as if the engine was overheating or had loss of fuel or only able to slowly exit the freeway to a safe place and call a tow truck, after 1 1/2 days of diagnosing and testing. I was able to drive the vehicle with no issues for approximately 4000 miles when the exact problem has occurred this past Friday 6-19-2026
Often while driving the car loses power as if the power went off or I ran out of gas,,, studder for a moment then pick up power to continue to drive is the best way I can describe it. Immediately after I get a notification on the dashboard saying maintenance something
