The nissan class action lawsuit engine defect has caught the attention of many vehicle owners. Drivers report sudden engine failures that put safety at risk. This case targets specific Nissan and Infiniti models with innovative but flawed engines. Owners claim the company hid known issues for years. If you own a 2019-2023 Nissan Altima, 2021-2023 Nissan Rogue, or 2019-2023 Infiniti QX50, this could affect you. The lawsuit, filed in 2025, seeks justice for repair costs and dangers on the road.
Background on Nissan: A Legacy of Innovation and Challenges
Nissan stands as a major player in the auto world. Founded in 1933 in Japan, the company has grown into a global brand. It sells millions of cars each year. Nissan focuses on technology to boost performance and fuel savings. One key advance is the variable compression turbo engine, or VC-Turbo. This system changes how pistons move to balance power and efficiency.
Yet, Nissan’s history includes bumps. Past issues with transmissions and timing chains led to recalls. For example, older models like the 2005-2010 Pathfinder faced coolant mixing with transmission fluid. This caused major breakdowns. Owners filed suits, and Nissan settled some. These events show patterns in how the company handles defects.
Today, Nissan operates in over 160 countries. It partners with Renault and Mitsubishi. In the U.S., Nissan North America handles sales and service. The firm employs thousands and invests in electric vehicles. But engine troubles persist. Complaints to the National Highway Traffic Safety Administration (NHTSA) number in the thousands for recent years. Data from 2025 shows over 500 reports on VC-Turbo issues alone.
Experts praise Nissan’s drive for new tech. The VC-Turbo debuted in 2018 with the Infiniti QX50. It promised better mileage without losing speed. Reviews called it groundbreaking. However, real-world use revealed flaws. Heat and pressure overwhelm parts, leading to failures. This sets the stage for the current nissan class action lawsuit engine defect.
What Is the VC-Turbo Engine?
Nissan designed the VC-Turbo to adapt. Traditional engines fix compression ratios. High ratios save fuel but risk knocking. Low ratios give power but waste gas. VC-Turbo shifts between 8:1 and 14:1 ratios. It uses a multi-link system to adjust piston height.
Key parts include:
- Main bearings: Support the crankshaft.
- Lower-links: Connect pistons to the crank.
- Control shafts: Manage the variable system.
This setup aims for 27-31 mpg in city driving. Models like the Altima hit 38 mpg on highways. Nissan marketed it as reliable for daily use. Ads highlighted smooth rides and low emissions.
But problems arise. Bearings wear fast under stress. Software glitches fail to adjust properly. Materials don’t hold up. Owners notice odd sounds early. By 20,000 miles, some engines seize. Repairs cost $5,000 to $10,000. Nissan often denies warranty claims, blaming drivers.
Compare to rivals. Honda’s Earth Dreams engines focus on efficiency without variable tech. They report fewer failures. Toyota’s Dynamic Force engines use similar ideas but avoid Nissan’s pitfalls. Stats from Consumer Reports show Nissan reliability scores below average in 2025.
The Defect Explained: Symptoms and Risks
The core issue in the nissan class action lawsuit engine defect is the variable compression system. It fails due to poor design. Bearings can’t handle heat. Links seize up. This chain reaction stops the engine.
Common symptoms include:
- Knocking or whirring noises from the engine bay.
- Hesitation when accelerating.
- Rough idling at stops.
- Sudden loss of power on highways.
- Stalling without warning.
- Excessive oil use, up to a quart per 1,000 miles.
These signs start subtle but worsen. One owner reported a 2022 Rogue stalling at 65 mph. No lights warned. This raises crash risks. NHTSA logs show accidents linked to similar failures.
Why does it happen? Manufacturing skips quality checks. Parts use subpar metals. Software doesn’t detect issues soon. Tests in labs miss real-road stress. Plaintiffs say Nissan knew from 2019 internal data.
Safety matters most. Engines failing mid-drive endanger lives. Families in Rogues face breakdowns on busy roads. Towing adds costs. Resale values drop 20-30% for affected models, per Kelley Blue Book.
Examples abound. A California driver spent $7,200 on a new engine for his Altima at 45,000 miles. Another in Texas had three repairs under warranty, but issues returned. Forums like Reddit fill with stories. Over 1,000 posts in 2025 discuss VC-Turbo woes.
Details of the Nissan Class Action Lawsuit Engine Defect
The nissan class action lawsuit engine defect began in July 2025. Filed as Becker et al. v. Nissan North America Inc. et al., Case No. 1:25-cv-00845. It’s in the U.S. District Court for the District of Delaware.
Plaintiffs include four owners. They bought vehicles expecting reliability. Instead, engines failed. Claims cover:
- Breach of warranty.
- Violations of the Magnuson-Moss Warranty Act.
- Fraud by concealment.
- Unjust enrichment.
The suit alleges Nissan hid the defect. Despite complaints, no full disclosure. A June 2025 recall covered 480,000 vehicles. But it only offers inspections and oil changes. Plaintiffs call it inadequate. No free engine swaps.
Status as of January 2026: Active. No settlement yet. Class certification pending. If approved, it includes all U.S. owners of affected models.
Law firms like Capstone Law APC handle similar cases. They won past Nissan suits on transmissions. For more on class actions, visit Laaster.
External sources detail the case. Top Class Actions reports on claims. The Lemon Firm explains defect origins. While a separate CVT case, Nissan Rogue CVT Lawsuit shows Nissan’s pattern.
Affected Models and Who Qualifies
The lawsuit targets specific vehicles with KR15DDT (1.5L three-cylinder) or KR20DDET (2.0L four-cylinder) engines.
List of models:
- 2019-2023 Nissan Altima.
- 2021-2023 Nissan Rogue.
- 2019-2023 Infiniti QX50.
Also, the recall adds 2022 Infiniti QX55 and 2019-2020 Altima variants.
To qualify:
- Own or lease one of these.
- Bought in the U.S.
- Experienced engine issues.
No mileage limit yet. Even low-mileage cars fail. Check your VIN on Nissan’s site or NHTSA.gov.
Stats: Over 1 million units sold. About 10% report problems, per owner surveys. California leads complaints, followed by Texas and Florida.
Nissan’s Response and Recall Details
Nissan issued Recall 25V-437 in June 2025. It affects 455,000+ vehicles. Dealers inspect bearings and links. If damaged, they replace parts. But owners say it’s spotty. Some get denied.
Company statement: “We prioritize safety. We’re addressing concerns.” Yet, no admission of defect in marketing.
Past responses show delays. In 2019, internal bulletins noted bearing wear. But no action until lawsuits.
Compare to 2021 CVT settlements. Nissan extended warranties and reimbursed repairs. Similar outcomes possible here.
How the Defect Impacts Owners Financially
Costs hit hard. Engine rebuilds average $6,000. Full replacements top $10,000. Add towing ($200+) and rentals ($50/day).
Lost work time adds up. One survey shows owners miss 3-5 days per breakdown.
Resale suffers. A 2022 Rogue with issues sells for $15,000 vs. $22,000 clean.
Insurance may rise after claims. Some policies exclude known defects.
Tips to mitigate:
- Document all repairs.
- Keep receipts.
- Report to NHTSA.
Similar Nissan Lawsuits in History
Nissan faces repeat suits. In 2013, timing chain issues in Maxima and Quest led to settlements. Owners got reimbursements up to $5,000.
CVT problems in 2014-2018 Rogue prompted extensions to 100,000 miles warranty.
Titan diesel exhaust defects in 2016-2019 models cost owners thousands. Class action ongoing.
These cases win when evidence shows concealment. The current nissan class action lawsuit engine defect follows suit.
Stats: Nissan paid over $100 million in settlements since 2010.
Legal Rights for Affected Owners
You have options under lemon laws. If repairs fail three times, demand buyback.
Magnuson-Moss Act covers federal warranties. State laws vary. California’s Song-Beverly Act offers strong protection.
Steps to take:
- Contact dealer for recall service.
- File NHTSA complaint.
- Consult lemon law attorney.
- Join the class action.
Firms offer free consults. No upfront fees in class cases.
Preventive Measures and Maintenance Tips
While defects aren’t your fault, maintenance helps.
- Change oil every 5,000 miles with synthetic.
- Monitor levels weekly.
- Avoid high-heat driving.
- Listen for noises.
If symptoms appear:
- Pull over safely.
- Tow to dealer.
- Don’t drive further.
Upgrades like aftermarket coolers may help, but void warranties.
