Ferrari’s brake-failure controversy has moved well beyond the courtroom battles in the United States. Outside the U.S. and United Kingdom, the issue has prompted recalls, regulatory intervention and renewed scrutiny across mainland Europe, China and Japan.

At the heart of the controversy is a defect that can potentially result in a serious reduction — and in certain circumstances, near-total loss — of braking capability. What began as a series of complaints and lawsuits has therefore become a much broader international compliance issue for Ferrari, involving government safety authorities and, in the United States, allegations concerning components supplied by Bosch.

The international record is particularly significant because these actions have not simply been driven by private litigation. In several markets, government regulators have independently required Ferrari to address the braking-system issue.

China: A Major Recall

China was one of the markets where Ferrari faced direct regulatory intervention.

In April 2022, Ferrari’s Chinese operation filed a recall with China’s State Administration for Market Regulation (SAMR) covering 2,222 imported Ferrari vehicles. According to the official Chinese recall notice, the campaign began on May 30, 2022, and covered vehicles manufactured between March 2, 2010 and March 12, 2019. The affected cars included the 458 Italia, 458 Speciale, 458 Speciale A, 458 Spider, 488 GTB and 488 Spider.

The Chinese regulator identified a problem with the brake-fluid reservoir cap. The cap could fail to provide the ventilation necessary to maintain atmospheric pressure inside the reservoir, potentially increasing the risk of brake-fluid leakage and a subsequent loss of braking capability.

Ferrari’s remedy was to replace the reservoir cap with an improved component and reprogram the instrument panel so that drivers would receive an updated warning when brake-fluid levels became too low.

And China did not stop there.

In August 2022, Ferrari expanded the recall to another 4,734 vehicles, covering a much wider collection of models, including the 430 family, 612 Scaglietti, California and California T, FF, F12 Berlinetta and TDF, LaFerrari and Aperta, GTC4 Lusso and Lusso T, 488 Pista and Spider, 812 Superfast and GTS, Portofino and Portofino M, Roma and F8 Tributo and Spider.

The expansion demonstrates just how broad the braking-system concern became in the Chinese market.

Germany and the Wider European Picture

Europe presented another important dimension because one of the companies identified in the wider dispute is Robert Bosch GmbH, the German supplier associated with the master-cylinder and brake-booster assemblies involved in the allegations.

The controversy has therefore extended beyond Ferrari itself and into questions concerning the manufacture and supply of braking components.

Court documents from the U.S. litigation identify the master-cylinder/brake-booster assembly as the component initially identified in Ferrari’s 2021 recall, with the documents stating that the brake components were manufactured by Bosch and installed in Ferrari vehicles.

That distinction matters. Ferrari is the vehicle manufacturer, but the braking assembly at the centre of the dispute was supplied by an outside component manufacturer.

European regulatory systems also operate differently from the American class-action system. Rather than relying exclusively on individual owners bringing claims, national authorities can require manufacturers to undertake corrective action when a vehicle is determined to present a safety risk.

The broader European implications therefore place additional pressure on Ferrari and its suppliers to demonstrate that affected vehicles have been properly identified and remedied.

Japan: Government-Directed Recall

Japan provides perhaps one of the clearest examples of the issue being handled through an official transport-safety system.

Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) documented a Ferrari recall involving the braking system. The official campaign described a scenario in which brake fluid could leak through a hydraulic seal near the brake booster. If the primary brake circuit lost its fluid, braking could become limited to the secondary circuit.

The Japanese documentation also identified a second potential problem involving the brake-fluid reservoir cap.

If the cap was tightened excessively, ventilation of the reservoir could be reduced. A vacuum could then develop inside the reservoir, potentially causing brake fluid from the secondary circuit to return to the reservoir. In the worst case, the brakes could fail to operate properly.

The Japanese recall covered multiple Ferrari models, including the 612 Scaglietti, F430, F430 Spider, 430 Scuderia, Scuderia Spider 16M and 488 Pista/488 Pista Spider. Japan’s Consumer Affairs Agency also records a separate 2022 corrective action covering seven Ferrari models, including the 458 Italia, 458 Spider, 458 Speciale, 458 Speciale A, 488 GTB, 488 Spider and J50, with 2,496 vehicles identified in that campaign.

The corrective action again involved replacing the reservoir cap and updating the vehicle’s warning system.

Japan’s official records therefore show that the issue was not simply a matter of private owners complaining about braking performance. It became an officially documented vehicle-safety matter requiring manufacturer action.

The Engineering Problem Behind the Controversy

This is where the Ferrari brake controversy becomes considerably more complicated.

According to court documents and technical material surrounding the litigation, the central concern involves the relationship between the master cylinder, brake booster, hydraulic seal and brake-fluid reservoir.

Ferrari’s original recall identified the master-cylinder/brake-booster assembly as the defective component. Later documentation described two possible failure modes.

In the first, an isolation seal inside the master cylinder can twist out of position. Brake fluid can then leak from the master cylinder into the brake booster, depleting the primary braking circuit. Ferrari’s documentation described the vehicle as being left with the secondary circuit operating under that condition.

The second failure mode is more serious.

The loss of fluid and altered ventilation conditions can create circumstances in which the secondary braking circuit is also compromised. Court documents describe the resulting braking capability as being “almost totally compromised.”

That is the central reason the issue has attracted so much attention.

A brake warning is one thing. A system capable of progressively losing hydraulic pressure is something else entirely.

The Bosch Connection

The Bosch connection has become particularly important in the legal debate.

The U.S. litigation names Bosch alongside Ferrari, with the allegations focusing on the master-cylinder/brake-booster assembly. Reuters reported in 2024 that a proposed class action accused Ferrari of failing to properly remedy the known brake defect, while Bosch was also named as a defendant because of its alleged role as the component supplier.

The allegations remain allegations within litigation, rather than an established finding that Bosch is legally responsible for every reported braking failure.

But technically, the distinction between Ferrari and Bosch matters because the dispute concerns both vehicle integration and component manufacture.

That is also why the engineering question is so important: determining whether the problem originated in the component itself, the way it was integrated into Ferrari’s braking system, the operating conditions created by the vehicle, the recall remedy, or some combination of those factors is central to determining responsibility.

Why the Recall Remedy Became Part of the Debate

The reservoir-cap replacement has itself become a major point of discussion.

Ferrari’s official corrective action in several markets was to replace the brake-fluid reservoir cap and update the vehicle software to provide an appropriate warning if brake-fluid levels became too low. China’s regulator records exactly that remedy.

However, litigation surrounding the defect has questioned whether replacing the cap addresses every possible failure mechanism.

That question became particularly important after Ferrari’s own documentation described multiple potential failure modes involving the master cylinder and brake booster. The U.S. court record describes the seal failure mechanism separately from the reservoir-cap issue.

This is ultimately the technical and legal fault line running through the controversy:

Does the reservoir-cap remedy address the entire braking-system problem, or does it primarily mitigate one of the conditions that can contribute to brake failure?

That distinction is critical when dealing with a safety system as fundamental as a vehicle’s brakes.

A Global Problem for Ferrari

Ferrari’s brake controversy is therefore considerably larger than one lawsuit or one country.

China required recalls affecting thousands of vehicles. Japan independently documented braking-system defects and corrective measures through its national vehicle-safety system. European scrutiny brings the added dimension of a major German component supplier, while litigation in the United States has placed Ferrari’s recall strategy and the underlying engineering issue under further examination.

The official regulatory records also show that the affected population is broader than a single Ferrari model. The campaigns have touched multiple generations and model families, from the 458 and 488 to the F430, California, FF, F12, LaFerrari, GTC4 Lusso, 812, Portofino, Roma and F8.

For a company whose reputation has been built around performance, precision and engineering, the significance of a braking-system controversy is obvious.

Ferrari can build a car capable of extraordinary speeds. But the engineering standard ultimately has to be judged just as critically by how reliably that car can stop.

And that is why this particular scandal continues to follow the company across borders.
