Car recalls happen when a company finds a big problem with its vehicles that could put drivers at risk. Sometimes, these problems come from mistakes in the design or poor-quality parts.

When that happens, millions of cars might need repairs. Some recalls are small, but others are so serious that they make headlines worldwide.

Poor engineering has led to some of the biggest recalls in automotive history. Issues like faulty brakes, engines catching fire, or airbags not working have forced companies to fix or replace millions of vehicles.

These mistakes can cost carmakers billions of dollars and damage their reputation, making people lose trust in their brands.

In some cases, dangerous defects are found after accidents happen. Car owners report problems, and when enough complaints pile up, investigations begin.

If the issue is widespread and serious, a recall is announced. Sometimes, companies act quickly, but other times, they delay, making the situation worse.

Some of the worst recalls have involved major car brands that people thought they could trust. Even popular manufacturers have made serious mistakes, leading to dangerous driving conditions.

In some cases, these problems have caused accidents, injuries, and even deaths, forcing companies to take responsibility.

12) The Takata Airbag Scandal A Deadly Defect

Airbags are designed to save lives by cushioning passengers in accidents. They were invented by John Hetrick and became one of the biggest safety improvements in cars.

However, not all airbags have been safe. A major scandal involving Takata, a Japanese company, revealed that some airbags were deadly instead of protective.

Takata was a well-known manufacturer of seatbelts and airbags for many car brands. But in 2013, it was discovered that its airbags could explode when deployed, sending sharp metal pieces into the vehicle.

This turned a life-saving device into a serious threat. Many people were injured, and some even lost their lives because of this defect.

Investigations showed that both Takata and Honda knew about the airbag issue but did not inform the authorities.

Reports revealed that the defect could have killed at least six people, yet the companies chose to stay silent. When the truth came out, Honda was fined $70 million, and Takata was penalized $14,000 for every day it failed to cooperate.

This became one of the largest recalls in history. By 2019, around 65 to 70 million vehicles were recalled, but 42 million still needed repairs.

Many cars with these faulty airbags remained on the road, putting millions of drivers at risk. The scandal damaged Takata’s reputation and led to massive financial losses.

The Takata airbag crisis serves as a lesson on the importance of vehicle safety. It showed how dangerous it is when companies hide defects instead of fixing them.

Today, automakers and safety organizations are more cautious, making sure that defective parts do not stay hidden for years. Despite this, the Takata recall remains a dark chapter in the history of car manufacturing.

11) Suzuki Celerio’s Brake Failure A Dangerous Defect

In 2015, Suzuki faced a serious problem when a major brake defect was discovered in the Celerio hatchback. The issue came to light during a brake test in the United Kingdom when an automotive journalist tried to stop the car from 80 mph. Instead of slowing down, the brake pedal went straight to the floor.

The cause of the failure was linked to a safety device that Suzuki had installed. This system was designed to retract the brake pedal in a crash to prevent injuries to the driver’s legs.

While this may sound helpful, it turned into a serious risk because the brake pedal could break under hard braking, making it impossible to stop the car.

In many countries, regulations require cars to have such safety systems to reduce injuries during accidents. When a crash occurs, the brake pedal can sometimes cause serious harm to the driver’s feet and legs, especially if the car’s firewall bends under impact.

Suzuki’s retraction system was meant to prevent this, but it created a life-threatening problem instead.

The defect was traced back to a small metal piece responsible for holding the brake pedal in place. Under heavy braking, this piece could snap, leaving the driver without any way to slow down.

Suzuki quickly realized the issue and issued a recall. The fix was simple—installing a stronger metal link to hold the brake pedal securely.

While the problem was resolved, the recall raised concerns about safety testing in vehicles. It showed how a feature meant to protect drivers could end up putting them in even greater danger.

Suzuki learned an important lesson, and the recall helped ensure that future models would not have the same flaw.

10) General Motors’ Engine Mount Failure A Costly Mistake

Engine mounts are essential because they keep the engine securely attached to the car. However, in the late 1960s, General Motors faced a huge problem when some of its engine mounts failed.

This was more than just a minor issue—it created a dangerous chain reaction that made cars difficult to stop.

At that time, cars used a cable to connect the gas pedal to the engine. When an engine mount broke, the engine would shift, causing the cable to get pulled and leaving the throttle stuck open. This meant that even if the driver took their foot off the accelerator, the car would keep moving forward.

To make things worse, the engine’s movement also affected the braking system. The sudden upward motion of the engine could pull the brake booster loose.

This made it much harder to press the brake pedal, requiring more force to slow the car down. With the throttle stuck and the brakes harder to use, drivers were put in a dangerous situation.

Despite the seriousness of the defect, General Motors initially refused to issue a recall. Edward Cole, GM’s president at the time, dismissed the problem, comparing it to something as common as a flat tire. However, the U.S. government saw it differently and forced GM to take action.

As a result, General Motors had to recall seven million vehicles to fix the problem. The company had to spend millions of dollars on repairs, and its reputation took a hit.

The recall served as a reminder that safety issues should never be ignored. If GM had acted sooner, it could have avoided the financial loss and the risk to drivers.

9) Ferrari’s Brake Fluid Leak A Risky Recall

Some car defects take years to become noticeable. This was the case with Ferrari’s brake fluid issue, which led to a major recall.

The problem affected 23,555 Ferrari vehicles built between 2005 and 2022, including high-performance models like the LaFerrari and the F60. The defect made braking unreliable, putting drivers at serious risk.

The issue was traced back to a faulty brake fluid reservoir cap. This cap did not vent properly, which caused a vacuum to form inside the reservoir.

Over time, this vacuum increased the chances of a brake fluid leak. If too much fluid leaked out, the brakes could fail partially or completely, making it difficult or even impossible to stop the car.

Brake failure is extremely dangerous, especially in high-speed sports cars like Ferraris. These vehicles are built for performance, and any issue with their braking system can lead to severe accidents.

Fortunately, Ferrari identified the problem and issued a recall before it led to widespread incidents.

The solution to the issue was relatively simple. Ferrari replaced the faulty cap with a new one that vents properly, preventing a vacuum from forming.

Additionally, a software update was introduced to alert drivers when brake fluid levels drop too low. This warning system helps prevent sudden brake failure by giving drivers time to refill the fluid.

8) Chevrolet Corvair A Classic with a Dangerous Design

The Chevrolet Corvair is one of the most controversial cars in American history. Unlike most cars of the 1960s, which had front-mounted engines, the Corvair was unique because it had a rear-mounted, air-cooled engine.

While this design was similar to the Porsche 911, the Corvair was much harder to control, leading to serious safety concerns.

One of the biggest critics of the Corvair was Ralph Nader, a well-known automotive safety advocate. He famously described it as a car where you could have a “one-car accident.”

His statement referred to the Corvair’s unpredictable handling, which made it easy to lose control, even without another vehicle involved. This reputation harmed Corvair’s image and raised concerns about its safety.

The main issue with the Corvair came from its rear suspension system. The car used half-shafts that connected the rear wheels to the differential.

The problem was that these half-shafts could flex when the suspension was under pressure. This caused the rear wheels to tilt at extreme angles, reducing the grip on the road and making it easy for the driver to lose control.

In the worst cases, the rear wheel could tuck under the car’s body, leading to a rollover. This was especially dangerous at high speeds or during sharp turns.

Many drivers found themselves in accidents because of this design flaw. The unpredictable handling and risk of rollovers made the Corvair one of the most controversial vehicles of its time.

7) Toyota’s Sticky Gas Pedal A Dangerous Recall

Imagine driving down the road when, suddenly, your gas pedal gets stuck, keeping the car accelerating uncontrollably.

This terrifying situation became a reality for some Toyota drivers in 2009 and 2010. The issue led to two major recalls and forced Toyota to stop selling certain vehicles until the problem was fixed temporarily.

The first recall, issued on November 2, 2009, was caused by incorrectly installed floor mats. These mats could slip out of place and trap the accelerator pedal, making it difficult for drivers to slow down.

Since the pedal remained pressed down, affected cars kept speeding up, putting drivers and passengers at serious risk of accidents.

However, the problem didn’t stop there. In January 2010, Toyota issued another recall after discovering a mechanical defect in the accelerator pedal itself.

This flaw could cause the pedal to stick even without a floor mat issue. Drivers of affected cars faced a dangerous situation where their vehicles could accelerate uncontrollably.

Due to the seriousness of the problem, Toyota immediately halted sales of the affected vehicles. The company had to manufacture new parts to fix the issue, causing delays and financial losses.

The recall impacted millions of Toyota owners and raised questions about vehicle safety and quality control.

Although Toyota eventually resolved the problem, the incident damaged the company’s reputation. It also highlighted the importance of thorough safety testing in the automotive industry.

The recall served as a lesson for car manufacturers, reinforcing the need to prioritize driver safety in all aspects of vehicle design and production.

6) Ford Pinto’s Deadly Fuel Tank Flaw

Getting rear-ended is always a bad experience, but for Ford Pinto owners in the late 1970s, it could be deadly. A major flaw in the car’s design made it extremely dangerous in rear-end collisions.

The problem involved the fuel filler neck, which could break off and cause fuel to leak, turning a minor accident into a fireball.

The fuel tank was positioned in such a way that, during a crash, the broken fuel filler neck could puncture the tank. This resulted in gasoline spraying into the car’s interior, creating a huge fire hazard.

If the leaked fuel ignited, the entire vehicle could go up in flames within seconds, putting the driver and passengers in extreme danger.

Ford became aware of the issue early on and realized that fixing it would cost just $11 per car. However, a leaked 1973 internal memo showed that the company decided against making the fix.

The memo even estimated how many people would die each year because of the defect. Ford concluded that it would be cheaper to handle lawsuits than to spend money on repairs.

This decision proved to be a costly mistake. After 27 recorded deaths linked to the flaw, public outrage forced Ford to act. The company had to recall 1.5 million Pintos to correct the problem. In the end, fixing all the vehicles cost Ford around $20 million, far more than the initial cost of $11 per car.

The Ford Pinto case became one of the most infamous examples of corporate negligence in automotive history. It highlighted the dangers of prioritizing profits over safety and led to stricter regulations in the car industry. This scandal remains a cautionary tale about the importance of ethical decision-making in vehicle manufacturing.

This design flaw posed a serious safety risk. If liquid reached the control electronics, it could either disable the airbags or cause them to deploy unexpectedly.

In both cases, this increased the chances of accidents and injuries. Given how crucial airbags are in protecting passengers, this issue raised major concerns among BMW owners and safety regulators.

While the lawsuit is still ongoing, BMW’s reputation has already taken a hit. The company had recently faced criticism for trying to charge customers a subscription fee for heated seats, a move that frustrated many buyers.

This latest problem only added to BMW’s growing list of controversies, making consumers question its commitment to quality and safety.

For now, BMW X7 owners—especially those driving the 2020 model—are advised to be extra cautious when using the cupholders.

Avoiding spills might help prevent any potential airbag malfunctions. However, until BMW addresses the issue, drivers are left dealing with an unusual but serious flaw in their high-end luxury SUVs.

4) Volkswagen’s Dieselgate Scandal

Volkswagen, known for its high-quality German engineering, faced one of the biggest scandals in the automotive industry—Dieselgate. While many companies have issued recalls for mechanical issues, Volkswagen’s case was different.

Instead of an accidental defect, the company was caught deliberately cheating on emissions tests, deceiving regulators and consumers worldwide.

The issue revolved around a hidden software trick called a “defeat device.” This program could detect when a vehicle was undergoing an emissions test and would temporarily adjust the engine to produce cleaner emissions.

Once the test was over, the car would switch back to normal mode, releasing far more pollutants into the air than legally allowed.

This made Volkswagen’s diesel vehicles appear environmentally friendly when, in reality, they were producing harmful levels of nitrogen oxides.

The scandal was uncovered in 2015, leading to a massive recall of Volkswagen and certain Audi diesel cars. While many of these vehicles could be fixed with a software update, about one million required mechanical repairs to meet emissions standards. The recall officially began in 2016, but by then, Volkswagen’s reputation had already suffered serious damage.

As a result of the scandal, Volkswagen admitted to wrongdoing and pleaded guilty to criminal charges. The company was forced to pay a staggering $40 billion in fines, settlements, and vehicle buybacks.

Additionally, one of Volkswagen’s former engineers, Oliver Schmidt, was sentenced to seven years in prison for his role in the deception.

3) Bentley Arnage’s Dangerous Wheel Nut Flaw

Bentley is known for its luxury and high-performance vehicles, and the Arnage R is a prime example of automotive excellence.

However, even ultra-expensive cars aren’t free from defects. In 2007, Bentley faced a recall issue with this model. Despite its premium price tag, the Arnage R was found to have a critical problem that could put drivers in danger.

The issue centered around the wheel nuts. Bentley discovered that some of the Arnage R vehicles had left the factory with incorrectly sized wheel nuts.

While this might sound like a small issue, the consequences were far more serious. The wrong size could lead to the wheels becoming loose or even detaching completely while driving. This created an incredibly dangerous situation for owners of the affected vehicles.

A wheel detaching while driving could cause a loss of control, leading to a potential accident. The recall was issued to correct this potentially life-threatening defect, ensuring that all affected vehicles were repaired with the correct wheel nuts.

Even luxury brands like Bentley are not immune to manufacturing errors, reminding us that no vehicle—no matter how expensive—is perfect.

2) Audi’s Unintended Acceleration Scandal

In the 1980s, Audi faced a major problem with its 5000 model. The issue was unintended acceleration, where the car would unexpectedly speed up when the driver shifted out of park. This meant that the car could take off without warning, making it dangerous for drivers and passengers.

Audi’s 5000 was the first car to gain significant attention for this issue, long before Toyota’s unintended acceleration problems in the 2000s.

Audi had to recall the 5000 three times between 1982 and 1987 to try to fix the problem. Despite these efforts, the company struggled to resolve the issue.

In the end, Audi decided to stop selling the 5000 in the United States in 1988, as the problem remained unresolved. Around 389,102 vehicles were affected by the unintended acceleration issue.

This scandal was a significant event in the history of automotive safety recalls, and it showed how difficult it could be for manufacturers to address major defects in their vehicles.

Audi’s experience with unintended acceleration is a reminder of the importance of rigorous testing and quality control to ensure the safety of all car models.
