- The problem
- 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.

- 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.
- The fix
- 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.

Engine recalls for the 2020 Nissan Altima
Engine complaints
The components and systems experiencing problems in my 2020 Nissan Altima S 2.5L include the engine, throttle body, and mass airflow (MAF) sensor system. The vehicle has experienced severe engine performance issues, including excessive fuel consumption, jerking, hesitation during acceleration, reduced engine power, and unexpected limp mode. The safety of myself and others were put at risk because the car did not accelerate anymore in the middle of on going traffic. It was me and my 2 underaged children in the car. Yes it has been confirmed by an independent service center. Yes, insurance representatives and others including mechanics. Check engine light appeared
SUBJECT: Improper Recall Remedy Denial - NHTSA Recall #25V437000 (Nissan R25A8/R25A9) Vehicle: 2020 Nissan Altima 2.0L VC-Turbo Mileage at Failure: 147,540 Incident Description: The vehicle experienced a sudden catastrophic engine failure resulting in a permanent no-start condition. The vehicle had been parked normally and completely failed to start the following morning. An independent certified mechanic inspected the vehicle and confirmed substantial metal shavings and bearing debris in the oil pan. The vehicle...

was towed to an authorized Nissan dealership service department for remedy under open NHTSA Campaign #25V437000. The dealership dropped the oil pan, re-confirmed the presence of metal bearing debris, and initially acknowledged this triggered an engine replacement under the recall. The claim was submitted to Nissan corporate warranty/Powertrain Call Center (PCC). Basis of Complaint (Recall Non-Compliance): Nissan North America and the dealership have officially declined the zero-cost recall remedy mandated by federal law, demanding nearly $10,000 for an engine replacement. Nissan claims the engine failed due to "loss of compression" rather than bearing breakdown. This claim is mechanically flawed: 1. In the KR20DDET VC-Turbo multi-link architecture, lower-link and crankshaft bearing degradation directly disrupts piston stroke geometry, scores cylinder walls, and causes severe loss of compression and eventual no-start. 2. The documented metal debris in the oil pan meets the exact diagnostic trigger in Nissan's recall bulletin for a full engine replacement. 3. Nissan has provided no diagnostic evidence showing an alternate source for the metal shavings in the pan. Nissan is evading its legal obligation under 49 U.S.C. § 30120 to remedy a known safety defect without charge. I request immediate ODI intervention regarding recall non-compliance.

When I am driving my car randomly states check engine and makes a beeping noise and then the engine starts to make some type of combustion noise and then slows down and then turns off.
The warming lights for different items come on at random. Examples :Low washer fluid, gas cap open, speedometer digital speed not showing.
The car stalls and began to jerk then shuts down the crash symbols comes on and goes off.
The CVT issue remains with this car even though I have complained. The car will randomly de accelerate and randomly accelerate which has cause minor fender bender. The car continue to studer and jerk and continues to show since of transmission issues. These cars need to be recalled before someone is seriously injured from the known CVT issues.

I received a Recall # R25B1 for my Nissan Altima 2020. I visited my local Nissan Dealer in Chelmsford, MA, on December 30, 2025. They explained that they saw an issue and that I would need a new engine. There are 32,000 miles on this vehicle. They began the process but were then told by Nissan Corporate that it did not meet the requirements of the recall, and they would not be replacing it. I am in the process of heading on a long driving trip and am very concerned with how this was handled. Nissan Customer...

Relations explained it wasn't covered under warranty, which has nothing to do with a recall. I am very frustrated and disappointed in Nissan. The mechanics at Nissan in Chelmsford took photos and sent them to Nissan, and they still denied it. With the car only having 32000 miles on it, it was probably if anything at the beginning of the failure. Please advise on going forward.
Need a new engine / gasket confirmed by pep boys. Been at the dealership a lot more than usual lately and they kept telling me everything is fine with my vehicle

I am writing to request immediate assistance regarding the recall inspection for my 2020 Nissan Altima Platinum. Last week I received a letter notifying me of an open recall and instructing me to have my vehicle inspected. I brought my car to my local Nissan dealership on Saturday. During the inspection, I was told that metal debris was found in the engine and that the vehicle would need a full engine replacement. I was asked to leave the car at the dealership and was told I would receive a loaner vehicle on...

Monday. After waiting all day today for an update, I was informed that Nissan declined the engine replacement because the debris found did not "qualify" under the recall. I was told the dealership would clear the debris out of the engine and that I could pick up the car tomorrow. I am very concerned about this decision. Metal debris inside an engine - especially during an active recall related to engine failure - raises serious safety and reliability issues. Simply clearing out the debris does not address the root cause or provide confidence that the vehicle is safe to drive. This matter is urgent, as I must drive more than 1,000 miles soon to take my medically complex daughter to a children's hospital. I need to trust that my vehicle is safe for long-distance travel. I am requesting a prompt review of my case and a second evaluation to determine whether an engine replacement or another appropriate remedy is necessary to ensure my vehicle's safety.
Unknown. The engine started have overheating issues but never was ran in the overheated zone. We took the car to the dealer and was told the head was cracked. We questioned how that was possible if we never ran it in the overheated zone. We were told they did not know but that several other Customers in the last few weeks have had the same issue. Then we heard about the recall but was told our car was not affected. It needs to be reevaluated. We never ran the car hot.

My car is said malfunction Loss of engine power
Since August of 2024 I noticed that my vehicle had strange noises coming from the engine and I was having a coolant loss but did not see anything on the ground. I then took my car to Nissan in New Orleans and they were recommending that I replace my entire engine. I'm not sure of their findings but still to this moment my vehicle still makes the same noise from the engine and still is having a coolant loss. I did notice that the coolant is overfilling in the reservoir tank and leaks out.
On the way to work a warning error message came across the dash board saying " Engine Malfunction Power reduced. Service now" then is turned off. The engine light didn't come on until a month later saying P0101. P0101 was fixed but the engine malfunction still comes and goes.
