Nissan's CVT Problem: A Decade of Defective Transmissions
Nissan has faced a sustained wave of class action litigation over its Continuously Variable Transmission (CVT), a type of automatic transmission used across many of its most popular models. Unlike traditional automatic transmissions with fixed gear ratios, CVTs use a belt-and-pulley system to vary gear ratios continuously, theoretically providing smoother acceleration and better fuel economy. In practice, Nissan's CVT implementation has generated thousands of consumer complaints, NHTSA investigations, and a mounting body of class action litigation alleging the transmissions are defective and fail prematurely.
The specific defects alleged vary somewhat by vehicle model and generation, but the core complaints center on: sudden loss of acceleration ("transmission shudder") while in motion, particularly dangerous in highway driving; premature transmission failure at mileage well below the vehicle's expected lifespan; excessive repair costs for a transmission that Nissan allegedly knew was prone to failure; and Nissan's alleged knowledge of these defects, documented through NHTSA complaint databases, Technical Service Bulletins, and internal testing, combined with failure to adequately disclose the issue or provide extended warranty coverage at the original point of sale.

Affected Nissan Models and Years
CVT defect litigation has targeted a wide range of Nissan models over the 2012-2022 model year range. Heavily litigated models include: Nissan Sentra, Nissan Rogue, Nissan Altima, Nissan Versa, Nissan Pathfinder, and the Nissan Murano. The 2018-2022 model years appear with particular frequency in current litigation, corresponding to Nissan's Xtronic CVT generation that consumer advocates argue represented insufficient engineering improvement over prior defective designs.
The litigation is not a single unified MDL, multiple parallel class actions in different federal districts have been certified (in some cases) or are pending certification. Some earlier Nissan CVT class actions produced negotiated settlements that provided extended warranty coverage and repair reimbursements to class members. The current wave of litigation targets ongoing defects in newer generation CVTs, alleging the settlements were insufficient and the core engineering problems were never resolved.
Beyond the CVT: Engine Defect Claims
Separate from the CVT litigation, Nissan has faced class action claims related to engine defects in specific models, most prominently the 2.5-liter four-cylinder engine used in several Altima, Rogue, and Pathfinder models. Claims include premature valve failure requiring engine replacement, excessive oil consumption leading to engine damage, and catalytic converter failures tied to engine performance issues. These claims proceed as separate class actions from the CVT litigation, though some plaintiffs have experienced both defects in the same vehicle.

Who Can File a Nissan Defect Claim?
Current and former owners of Nissan vehicles with CVT or engine defects during the class period may qualify. The class definition for each specific case varies by model, year, and defect type. To evaluate your claim: document the specific defect symptoms you've experienced, compile dealer service records showing CVT or engine-related repairs and associated costs, note NHTSA complaint numbers if you've filed a safety complaint, and retain any communications from Nissan dealers regarding the defect. Class members who paid out-of-pocket for CVT replacements or major engine repairs are typically the highest-priority claimants with the most direct economic damages.
How to File a Claim or Get Help
If you believe you qualify based on the eligibility criteria outlined above, the next step is a free consultation with an experienced attorney who handles this case type. Most plaintiff-side attorneys offer no-cost initial evaluations and work on contingency, meaning you pay nothing unless your case results in a recovery.

Nissan Class Action Lawsuit Engine Defect 2026: What You Need to Know: Frequently Asked Questions
Answers to the most common questions about this case and your legal options.
Which Nissan models have the CVT defect?
CVT defect class actions have targeted Nissan Sentra, Rogue, Altima, Versa, Pathfinder, and Murano across multiple model years, with the 2012-2022 range most heavily represented in litigation. Specific models and years included in any given class action vary, check the official case websites or consult an attorney to determine whether your specific vehicle is covered.
What does a CVT defect feel like?
Common symptoms cited in the Nissan CVT litigation include: jerking or shuddering during acceleration, particularly at highway speeds; sudden loss of power or hesitation; delayed throttle response; overheating transmission warning lights; transmission failure requiring dealer service; and in severe cases, complete loss of forward propulsion while driving. These symptoms often first appear between 50,000 and 100,000 miles.
Does Nissan cover CVT repairs under warranty?
Nissan's standard powertrain warranty covers 5 years/60,000 miles. Extended coverage may be available under Technical Service Bulletins or extended warranty programs Nissan has issued for specific CVT issues. Prior class action settlements provided extended warranty coverage for some affected owners. Owners whose warranty has expired and who have paid out-of-pocket for CVT repairs are the primary class action claimants.
Can I file a Nissan CVT claim if I already sold my car?
Yes, former owners who paid for CVT repairs during their ownership may have claims for those repair costs. Your damages are the out-of-pocket amounts you paid, not future repair costs. Retain documentation of all CVT-related service records and invoices from your ownership period.
Is there a Nissan CVT recall?
Nissan has issued specific recalls for some CVT-related issues in limited model years and configurations, but the litigation alleges these recalls have been insufficient and that the underlying engineering defect affecting a much broader population of vehicles has not been addressed. Check the NHTSA recall database (nhtsa.gov) using your VIN to identify any applicable recalls for your specific vehicle.
