The Nissan VC-Turbo engine lawsuit involves allegations that certain Nissan and Infiniti vehicles equipped with variable-compression turbocharged engines can suffer serious engine problems, including bearing failures, loss of power and complete engine failure.
A proposed class action was filed in federal court in Delaware in July 2025. The lawsuit focuses on 2021–2023 Nissan Rogue, 2019–2023 Nissan Altima and 2019–2023 Infiniti QX50 vehicles.
The lawsuit came shortly after Nissan announced a major recall involving 443,899 vehicles equipped with certain 1.5-liter and 2.0-liter VC-Turbo engines. The recall covers additional model years and also includes the 2022 Infiniti QX55.
As of August 2026, the class action remains unresolved. There is no announced class-action settlement or approved payout program for this lawsuit.
What Is the Nissan VC-Turbo Engine?
VC-Turbo stands for Variable Compression Turbo.
Unlike a conventional engine, Nissan’s VC-Turbo technology can change the engine’s compression ratio depending on driving conditions. The system was designed to provide a balance between performance and fuel efficiency.
Nissan used VC-Turbo engines in several Nissan and Infiniti models, including the Rogue, Altima, QX50 and QX55.
The engines involved in the recall include:
- KR15DDT — 1.5-liter three-cylinder VC-Turbo
- KR20DDET — 2.0-liter four-cylinder VC-Turbo
The technology itself is not the subject of a court finding that every VC-Turbo engine is defective. Instead, the lawsuit alleges that certain engines contain defects involving internal engine bearings and the variable-compression system.
What Is the Nissan VC-Turbo Lawsuit About?
The proposed class action is known as Becker et al. v. Nissan of North America, Inc., et al., Case No. 1:25-cv-00845, in the U.S. District Court for the District of Delaware.
The lawsuit was filed on July 8, 2025.
The plaintiffs allege that certain VC-Turbo engines have defects involving the engine’s main bearings and/or lower-link components.
According to the allegations, these problems can cause:
- Knocking noises
- High-pitched whirring
- Rough idling
- Hesitation
- Loss of power
- Stalling
- Sudden engine failure
- Expensive engine repairs or replacement
The plaintiffs also allege that Nissan knew or should have known about the alleged defect and failed to adequately disclose the problem to consumers.
These remain allegations in the lawsuit. They should not be presented as a final court finding against Nissan.
Which Nissan Vehicles Are Involved in the Lawsuit?
The proposed class action specifically identifies these vehicles:
| Vehicle | Model Years Mentioned in Lawsuit |
| Nissan Rogue | 2021–2023 |
| Nissan Altima | 2019–2023 |
| Infiniti QX50 | 2019–2023 |
The lawsuit focuses on vehicles equipped with the affected VC-Turbo engines.
The 2022 Infiniti QX55 also uses the 2.0-liter VC-Turbo engine and is included in Nissan’s separate safety recall, although it is important not to automatically assume that every vehicle covered by the recall is also part of the proposed class in the lawsuit.
What Is the Nissan VC-Turbo Engine Recall?
The lawsuit should be considered alongside a major Nissan safety recall announced in 2025.
Nissan recalled 443,899 vehicles because certain engine bearings may contain manufacturing defects that can lead to engine failure. NHTSA’s recall documents identify the affected vehicles as:
- 2021–2024 Nissan Rogue
- 2019–2020 Nissan Altima
- 2019–2022 Infiniti QX50
- 2022 Infiniti QX55
The recall involves both 1.5-liter and 2.0-liter VC-Turbo engines.
How Serious Is the Recall?
NHTSA’s recall description states that defective engine bearings can lead to engine failure.
An engine that fails while a vehicle is being driven can increase the risk of a crash.
Nissan estimated that approximately 1.2% of the recalled vehicles, or about 5,327 vehicles, were expected to actually contain the defective bearings.
That does not mean that 1.2% of all VC-Turbo engines will necessarily fail. It refers to Nissan’s estimate of vehicles within the recalled population that may contain the affected parts.
What Does Nissan’s Recall Repair Involve?
Nissan’s recall procedure involves inspecting the engine for evidence of the problem.
Dealers can inspect the oil and oil pan for metal debris.
If debris is discovered, the engine may need to be replaced.
If no debris is found, the required repair depends on the engine and vehicle.
For certain 1.5-liter VC-Turbo engines, the recall remedy can include:
- Oil-pan gasket replacement
- Fresh engine oil
- Engine-control-module reprogramming
For affected 2.0-liter engines, the remedy can include an engine-oil replacement when no debris is found.
These recall repairs are performed free of charge through the recall program.
Why Did Owners File a Lawsuit After the Recall?
The plaintiffs in the class action argue that the recall does not fully resolve the problems they experienced.
The lawsuit alleges that owners may have already paid for:
- Diagnostic work
- Engine repairs
- Engine replacement
- Towing
- Other related expenses
The complaint also alleges that the recall remedy does not provide sufficient compensation for all affected consumers.
This is one of the important differences between a recall and a class action lawsuit.
A recall is a safety-related corrective action by the manufacturer.
A class action seeks legal remedies for consumers who claim they suffered losses because of the alleged defect.
Does the Recall Mean Nissan Admitted the Engine Was Defective?
Not necessarily.
Nissan’s recall acknowledges that certain engine bearings may have manufacturing defects and that those defects can lead to engine failure.
However, the separate class-action lawsuit makes broader allegations concerning the design, workmanship and disclosure of the VC-Turbo engine problems.
A recall should therefore not automatically be described as a court finding that Nissan intentionally sold defective vehicles.
What Problems Are Owners Reporting?
The lawsuit describes several symptoms allegedly associated with the engine problem.
Knocking or Whirring
Some plaintiffs reported unusual engine sounds, including knocking and high-pitched whirring.
Rough Idling
The engine may run unevenly or feel unstable while the vehicle is stopped.
Hesitation
Drivers may experience a delay or hesitation when accelerating.
Loss of Power
A serious engine problem can cause the vehicle to lose power.
Engine Failure
The most serious alleged consequence is complete engine failure.
An engine failure while driving can create a significant safety concern because the vehicle may suddenly lose propulsion.
Is There a Nissan VC-Turbo Class Action Settlement?
No settlement has been announced for the Becker VC-Turbo class action as of August 2026.
The lawsuit is still in the litigation process.
There is therefore no confirmed:
- Settlement amount
- Settlement check
- Class-action payout
- Claim form
- Payment deadline
- Final settlement administrator
Consumers should be cautious about websites claiming that Nissan VC-Turbo owners can already claim a specific amount of money.
Is the Nissan VC-Turbo Lawsuit a Class Action?
It is a proposed class action.
That distinction matters.
A lawsuit can be filed as a proposed class action, but the court must still decide whether the requirements for class certification are satisfied.
As of the latest available information, the case has not resulted in a final class certification or settlement.
Therefore, it is premature to say that every owner of an affected Nissan or Infiniti vehicle is automatically a member of a certified class.
What Is the Current Nissan VC-Turbo Lawsuit Status in 2026?
The case remains in its early stages.
According to recent legal reporting, the lawsuit is currently stayed, with no settlement or class certification in place as of mid-2026.
This means there is currently no approved consumer payout program resulting from the class action.
The separate Nissan safety recall, however, is an existing remedy that affected vehicle owners should take seriously.
Can Nissan Owners Still Get a Free Engine?
If your vehicle is covered by Nissan’s recall and the inspection determines that the engine requires replacement under the recall remedy, Nissan is responsible for performing the covered repair without charge.
The recall does not mean every affected vehicle automatically receives a new engine.
The inspection determines the appropriate remedy.
Owners should check their VIN through the official Nissan or NHTSA recall system to determine whether their vehicle has an outstanding recall.
What Should Owners Do If Their Engine Has Problems?
If you own an affected Nissan or Infiniti vehicle, keep detailed records.
Useful documents include:
- Repair invoices
- Dealer service records
- Engine diagnostic reports
- Towing receipts
- Engine replacement invoices
- Oil-change records
- Recall notices
- Photos or videos of engine symptoms
- Communications with Nissan or the dealer
These records may become important if a consumer later seeks reimbursement or other legal relief.
If your vehicle is subject to the recall, owners should also contact an authorized Nissan or Infiniti dealer regarding the recall inspection.
Does the Nissan VC-Turbo Lawsuit Include Infiniti?
Yes, certain Infiniti vehicles are involved.
The proposed class action specifically names the 2019–2023 Infiniti QX50.
The separate recall also includes the 2022 Infiniti QX55.
Again, the recall population and lawsuit class are not necessarily identical.
What About the Nissan Rogue 1.5 VC-Turbo?
The Nissan Rogue is particularly important because the 1.5-liter three-cylinder VC-Turbo engine is included in the recall.
The recall covers 2021–2024 Rogue models, while the proposed class action identifies 2021–2023 Rogue models.
This difference demonstrates why owners should check both:
- Whether their vehicle has a safety recall
- Whether their specific vehicle falls within the proposed lawsuit class
They are two separate legal and regulatory questions.
What About the Nissan Altima 2.0 VC-Turbo?
The lawsuit identifies 2019–2023 Nissan Altima vehicles equipped with the VC-Turbo engine.
The recall, however, covers 2019–2020 Altima vehicles.
Therefore, an Altima owner should not assume that every model year mentioned in the lawsuit has the same recall status.
What About the Infiniti QX50?
The lawsuit identifies 2019–2023 Infiniti QX50 models.
The recall covers 2019–2022 QX50 vehicles.
Owners should use the vehicle identification number rather than relying solely on the model year.
