Mazda CX-90 Class Action Lawsuit, What Owners Need to Know About Brake and Lane-Keep Defect Claims

A class action lawsuit filed in March 2026 accuses Mazda Motor Corporation of knowingly selling 2024–2026 CX-90 SUVs with defective braking systems and a malfunctioning Lane-Keep Assist feature that fights against the driver’s own steering. The lawsuit claims Mazda was aware of both defects before the CX-90 launched in the United States — and concealed them from buyers. No settlement has been reached. This case is in early litigation.

Where This Case Stands

• The lawsuit was filed on March 17, 2026, and is in early litigation. No hearing dates, class certification schedule, or settlement talks have been publicly announced.
• Mazda has not filed a public response to this complaint.
• A separate California class action over CX-90 brake squealing (filed by plaintiff Daniel Green) reached a private settlement in March 2026 — but the court dismissed it without class-wide relief, meaning the settlement covers only the individual plaintiff. Other CX-90 owners received nothing from that case.
• No claim form exists. Consumers cannot file for compensation at this time.

What Is the Mazda CX-90 and Who Buys It?

The Mazda CX-90 is the Japanese automaker’s flagship three-row crossover SUV, launched in the United States in 2023. Mazda markets it directly to families, emphasizing its three-row seating, cargo capacity, and advanced safety features including Lane-Keep Assist. It sits at the top of Mazda’s lineup and carries a price tag that reflects its premium positioning.

The lawsuit argues that the CX-90’s core appeal — its safety credentials — is precisely what makes the alleged defects so serious. A family-focused SUV that squeals unpredictably and steers against the driver’s own input, the complaint suggests, is not the vehicle Mazda represented it to be.

What Does the Lawsuit Say Is Wrong With the CX-90?

The 47-page complaint identifies two interconnected problems that the plaintiff says Mazda has known about since before U.S. sales began — and has consistently failed to fix.

The Brake Defect

The lawsuit claims the braking system components in affected CX-90s deteriorate prematurely and excessively — far faster than the 30,000 to 65,000 miles a set of brake pads should typically last. According to the complaint, some CX-90 owners have had to replace brake pads within the first 1,000 miles of ownership.

The deterioration produces a persistent, loud, high-pitched squealing noise when brakes are applied during normal driving. The complaint says the noise is not just an annoyance — it actively distracts drivers and, crucially, may desensitize them to the warning sounds that typically signal brake failure. Drivers who learn to tune out constant squealing may ignore the sounds their car makes when the brakes are genuinely giving out. The lawsuit also reports juddering and vibration when brakes are applied, making vehicle handling harder and less predictable.

The Lane-Keep Assist Defect

Lane-Keep Assist is a safety system that uses cameras to detect lane markings and provides gentle steering corrections to keep a vehicle centered in its lane. In well-functioning systems, the corrections are subtle — designed to assist, not override, the driver.

The complaint says the CX-90’s Lane-Keep Assist does something fundamentally different: it applies what the lawsuit calls “inappropriate and overly corrective” steering that directly opposes the driver’s own steering input. Instead of helping the driver stay in lane, the system actively fights them — pushing the wheel in the wrong direction. The lawsuit warns this dramatically increases the risk of erratic or sudden steering movements, particularly if the system engages unexpectedly or disengages abruptly mid-correction, leaving the driver momentarily wrestling with an unintended steering input.

What Did the Plaintiff Experience?

Plaintiff James R. Burnell’s story illustrates the pattern the lawsuit alleges is widespread among CX-90 owners. Burnell purchased a new 2024 Mazda CX-90 in Virginia. He initially rejected the first vehicle at the dealership because the Lane-Keep Assist system was engaging incorrectly. He then purchased a second CX-90 — which soon developed the same problems.

Over the following months, Burnell returned to Mazda dealerships repeatedly. Technicians diagnosed both the brakes and the Lane-Keep Assist system as “normal.” They scuffed brake rotors, applied anti-squeal compound to pads, and replaced brake components under warranty. Each time, the fix was temporary or ineffective. The brakes would resume squealing within days of each repair visit. One dealership eventually told Burnell the brake defects were “unfixable.”

According to the complaint, Burnell’s CX-90 spent approximately 36 days at Mazda dealerships since purchase — and the problems were never resolved.

Did Mazda Know About These Problems Before Selling the CX-90?

The complaint argues Mazda had advance knowledge of both defects and chose to conceal them. The lawsuit points to several pieces of evidence supporting this claim.

Before launching the CX-90 in the United States in 2023, Mazda had already released a substantially identical vehicle in Japan and Europe. That earlier release generated extensive consumer complaints — particularly about the Lane-Keep Assist steering behavior — that Mazda collected and analyzed. The lawsuit says Mazda routinely gathers real-time data from its dealer network about complaints, service repairs, and parts replacement rates, giving the company precise visibility into where problems are emerging.

The complaint also references Mazda service alerts issued about brake noise, judder, and dragging in its vehicles — alerts the lawsuit argues reflect the company’s awareness of the underlying brake issue. Additionally, Mazda issued a safety recall in January 2024 for CX-90 steering issues involving sticky steering wheels. The complaint says that recall did not address the Lane-Keep Assist malfunction, and that the steering problems continued after the recall repairs were performed.

The National Highway Traffic Safety Administration has also opened a federal investigation to determine whether that 2024 recall adequately resolved the sticky steering wheel issue in 2024 Mazda CX-90s.

Who May Be Affected?

The Burnell lawsuit currently seeks to represent a class of Virginia residents who purchased or leased a model year 2024–2026 Mazda CX-90 for personal, family, or household use within the applicable statute of limitations period.

The complaint does not currently seek nationwide class certification. However, CX-90 owners across the country — many of whom have posted complaints online about identical brake squealing and Lane-Keep Assist problems — are watching this case closely given the widespread nature of the reported issues.

You do not need to take any action right now. If this lawsuit proceeds toward class certification and a settlement is eventually reached, affected Virginia consumers will typically receive a notice and have the opportunity to file a claim at that time.

The Broader Pattern of Mazda CX-90 Complaints

The Virginia lawsuit is not the first legal challenge over these issues. A separate class action filed in California by plaintiff Daniel Green alleged substantially similar brake defects in 2024–2025 CX-90 vehicles. That California case reached a private settlement in early 2026 — but the court dismissed it on March 21, 2026, without extending any class-wide relief to other CX-90 owners. The terms of that individual settlement were not made public, and the claims of putative class members were dismissed without prejudice, meaning other owners retained the right to pursue their own claims.

Meanwhile, CX-90 owners on automotive forums and complaint databases have reported nearly identical experiences: brake squealing within hundreds of miles of purchase, multiple dealer visits with temporary fixes, and Lane-Keep Assist systems that feel more dangerous than helpful.

Frequently Asked Questions

Is there a settlement I can claim from the Mazda CX-90 lawsuit? 

No. The Virginia class action filed by James Burnell was filed on March 17, 2026, and is in early litigation. There is no settlement, no claim form, and no money available to consumers at this time. If a class-wide settlement is reached, this article will be updated.

What model years of Mazda CX-90 does this lawsuit cover?

The Burnell complaint targets model year 2024–2026 Mazda CX-90 vehicles purchased or leased in Virginia for personal or household use. The earlier California lawsuit focused on 2024–2025 model years but was dismissed without class-wide relief.

What is Lane-Keep Assist and why is it dangerous when it malfunctions?

 Lane-Keep Assist is a driver assistance system that uses cameras to detect lane markings and applies small steering corrections to keep the vehicle centered. When it malfunctions as alleged in this lawsuit — steering forcefully against the driver’s own input — it can cause the driver to lose control of steering direction, particularly if the system activates unexpectedly or suddenly disengages.

My CX-90 brakes squeal. What should I do? 

Document every instance. Take your vehicle to an authorized Mazda dealership and request a written record of every service visit, diagnosis, and repair attempt. Keep all receipts and repair orders. This documentation could be important if a class action settlement is eventually reached or if you pursue a warranty or lemon law claim independently.

Does Virginia have a lemon law that might help CX-90 owners?

 Yes. Virginia’s Motor Vehicle Warranty Enforcement Act — commonly called Virginia’s Lemon Law — may provide relief to consumers whose new vehicles have defects that substantially impair the vehicle’s use, value, or safety and have not been repaired after a reasonable number of attempts. Consult a consumer protection or lemon law attorney in Virginia to evaluate whether your situation qualifies.

Do I need a lawyer to follow this case? 

No. You can monitor this case at no cost through the federal court’s PACER system at ecf.vaed.uscourts.gov using Case No. 2:26-cv-00256. If a settlement is reached, class members typically receive direct notice and can file claims without hiring an attorney.

What happened to the California Mazda CX-90 brake lawsuit? 

That case — filed by Daniel Green against Mazda Motor of America in California — reached a private settlement between the individual plaintiff and Mazda and was dismissed on March 21, 2026. The court dismissed the claims of all other putative class members without prejudice, meaning no class-wide compensation was distributed and other CX-90 owners received nothing from that case.
