How Often Do Cars Break Down? - Roadside Emergency and Vehicle Failure Statistics (2026)

Last updated: March 2026

Every day, nearly 200,000 vehicles break down in the United States alone. That’s more than 130 breakdowns per minute.

And yet, most drivers still assume it won’t happen to them.

Every year, tens of millions of drivers experience vehicle breakdowns, and many of them are completely unprepared for what happens next.

Whether it’s a dead car battery, a flat tire, or engine failure, roadside emergencies are far more common, predictable, and often preventable than most people realize.

This report breaks down the real statistics behind roadside emergencies, what actually causes breakdowns, and why most drivers are caught off guard. The goal is raising awareness and helping driver reduce the risk of accidents and breakdowns caused by human error.

What are roadside emergencies and vehicle failures?

Roadside emergencies and vehicle failures refer to situations where a vehicle becomes disabled due to mechanical issues such as battery failure, flat tires, engine problems, or accidents, often requiring immediate assistance or repair.

Pro Tip - Most roadside breakdowns aren’t random. But many car battery and electrical failures are preventable failures waiting to happen. The difference between being stranded and getting back on the road quickly often comes down to one thing: preparation.

Key Statistics - Roadside Emergency & Vehicle Failure Statistics

Out on the road, things go wrong, and often when you least expect them. Dead batteries, blowouts, breakdowns… It’s not a matter of if, but when. These key roadside emergency and vehicle failure statistics show exactly what drivers are up against, and why preparation matters.

• 69 million vehicle breakdowns annually in the United States.

• There are approximately 189,000 breakdowns every day.

• More than 700 people are killed each year due to breakdowns.

• Breakdowns cost the American economy $41 billion per year.

• The annual cost of roadside assistance in the US is $7 billion.

• Roadside breakdowns lead to about 30 million lost workdays.

• 150 million people sit in traffic caused by breakdowns every year.

• 44% of cars on the road are models from 2014 or earlier.

• Vehicles aged 10 years or older account for over two-thirds of all roadside assistance calls.

• AAA received an estimated 215,000 service calls for electric vehicles in 2024.

• 27+ million roadside assistance calls per year.

• Roughly 30% of summertime breakdowns are caused by battery failure.

• Vehicles 10+ years old = 2x more likely to break down.

• Cold weather can reduce the power of EV and regular car batteries by up to 60%.

Roadside Emergency Statistics (The Big Picture)

People never plan to wind up stranded on the side of the road. But it happens. And as the data shows, breakdowns are far from rare events. Especially in big cities and metropolitan areas, breakdowns occur almost constantly.

In the United States alone, it's estimated that there are about 69 million vehicle breakdowns each year, or roughly 189,000 per day. If you break those numbers down even further, there are approximately 131.25 breakdowns per minute, every day.

Furthermore, about 1 in 3 drivers experience a breakdown. So statistically, if it's not you broken down on the side of the road, there's a good chance it could be your wife, mother, father, teen, or somebody else close to you.

All this to say, we're not talking about fringe scenarios. Roadside emergencies are a normal part of driving. And beyond inconvenience, breakdowns have real financial and physical consequences.

For example, breakdowns lead to traffic congestion, lost time, car repairs, and fatal accidents.

Studies also show that roughly 150 million people sit in traffic caused by breakdowns every year, and that breakdowns lead to about 30 million lost workdays annually. The economic cost of that is estimated at about $41 billion annually. And the annual cost of roadside assistance in the United States is $7 billion.

But that's not all.

According to AAA, the average annual maintenance cost for passenger vehicles increased to $1,234 in 2025, representing a 12% jump from the previous year. Meanwhile, other studies state that the average American pays between $1,200 and $1,475 per year for car maintenance and repairs.

But when you add all these costs together, you see it's not just individuals footing the bill when cars break down. The country as a whole pays a price.

Pro Tip - If you drive long enough, a breakdown isn’t a possibility... It’s a probability. That's why it's crucial for drivers to understand the risks of driving, and to prepare as best they can. Learn how to prevent blowouts and flat tires, check and change your car battery before it fails, and keep yourself prepared by storing a jump starter or other emergency gear in your trunk.

Roadside Assistance Statistics

We're sure there are plenty of people out there prepared for roadside emergencies, but the vast majority of drivers are not. When things go wrong, drivers rely heavily on roadside services, like AAA, and the volume of calls is massive.

AAA alone responds to over 27 million roadside assistance calls per year. In previous years, totals have exceeded 30 million service calls annually. Approximately 13 million of those calls require towing, and about 7 million involve battery issues.

Combined, those two categories account for about 74% of all roadside assistance calls.

According to CAA, 25% of summertime call-outs are for tire-related issues, and 30% are for battery problems. In one UK study, it was estimated that about 8.6 million cars likely have weak 12-volt batteries. Other common issues include overheated engines due to low coolant levels, worn-out brakes, and failing alternators.

The research also shows that breakdowns affect drivers across all vehicle types. New cars, old cars, electric vehicles, and hybrids all experience problems. But vehicle age plays a major role. In fact, vehicles 10+ years old are believed to be twice as likely to break down as newer vehicles.

Pro Tip - The data shows that most roadside emergencies are not catastrophic. They’re predictable mechanical failures, like old, weak 12V batteries, worn-out or underinflated tires, and an overall lack of maintenance and preparation before hitting the road.

How Dangerous Is Breaking Down on the Highway? (Fatal Crash Statistics)

Breaking down on the side of the highway isn’t just inconvenient. It can also be deadly. In fact, the number of motor vehicle deaths related to breakdowns is quite shocking.

While most drivers think the risk ends once they pull over, data show that being stopped on or near the roadway often creates a serious secondary-crash risk. It's estimated that between 566 and 700 people are killed each year, and more than 14,000 people are injured due to roadside breakdowns and secondary crashes.

If you do that math, it works out to between 1 and 2 traffic deaths per day, with 300+ deaths per year involving pedestrians near stopped vehicles.

But it's not just drivers or passengers who are killed and injured. In 2017, one study showed that 41 towers were killed, and 980 were injured while on the job trying to help people who had broken down on the side of the road.

Ultimately, about 95% of crashes involving stopped vehicles happen when a moving vehicle strikes a stationary one. When you're on or near a highway, even a small mistake can be catastrophic.

Pro Tip - In many cases, people aren’t hurt or killed in the original breakdown. They’re injured after exiting the vehicle. This helps illustrate the importance of having essential emergency gear in your car, which includes jump starters, air compressors, traffic alarms, and road flares.

Practical Takeaway - The Importance of Improving Vehicle Safety, Reducing Traffic Fatalities & Crash Deaths

The data shown so far reinforces the importance of maintaining passenger cars before breakdowns happen. Then, when they do occur, getting your car off the roadway or making yourself and your vehicle visible to other drivers is crucial.

But it's hard to know what to do or to have the right tools when you're not prepared for potential breakdowns.

That's why preparation matters, perhaps more than anything else. Because once your vehicle is disabled, you’re no longer just a driver. You’re now part of a high-risk roadside scenario.

Pro Tip - In recent years, there's been a significant increase in drivers undertaking routine vehicle maintenance on their own. However, there's also been an increase in hand and power tool injuries, highlighting the importance of using caution, using the right tools, and always being prepared. 

Leading Causes of Roadside Failures

Most breakdowns come down to a handful of predictable issues:

• Weak or dead batteries

• Flat or damaged tires

• Engine/cooling system failures

• Alternator or electrical issues

• Fuel-related problems

However, studies show that about 30% of breakdowns are caused by battery failure, making it one of the most common causes of roadside failures.

This figure also increases in cold weather, when car batteries can lose up to 60% of their capacity at temperatures below freezing. Even at moderately cold temperatures, batteries can be 35% weaker. This explains why AAA reports up to an 85% spike in battery-related service calls during extreme cold weather events.

Another issue is that batteries typically only last 3–5 years before the risk of failure increases.

Yet nearly half of the cars on the road are models from 2014 or earlier.

Add to that the fact that many drivers don't test their batteries until they fail. And you've got yourself an equation in which a significant number of cars on the road are at heightened risk of breaking down due to a faulty battery.

Pro Tip - Winter doesn’t create problems. It exposes already weak batteries. That's why it's crucial to check and maintain your battery, replace it before it fails, and always keep a jump starter or jumper cables in your vehicle to jump start your car if the battery fails.

Key Takeaways & Insights - What These Statistics Mean For Drivers

The data shows that most breakdowns aren’t random. They’re the result of predictable failures, such as aging batteries and a lack of maintenance. In fact, some of the most overlooked risk factors are the little things.

Many drivers worry about major mechanical failures. But the data shows that small, preventable issues like batteries and tires are the real problem.

And if there’s one insight that matters most, it’s that you don’t need to prevent every breakdown; you just need to be prepared for the most common ones. This means monitoring your battery (especially after 3 years), checking and maintaining your tires, preparing for cold weather, and keeping basic emergency tools available.

Because when breakdowns happen, and statistically, they will, the difference between a minor inconvenience and a serious problem is preparation.

How to Prepare for a Roadside Emergency (Based on the Data)

The bad news is that if you drive, you're likely to experience a breakdown at some point.

However, roadside emergencies are less about bad luck and more about poor preparation, which means there are several things you can do to reduce your risk of vehicle failure.

After all, the most common roadside emergencies are also the easiest to prepare for. Here's a closer look at how to prepare for worst-case roadside scenarios.

Be Prepared for Battery Failure (The #1 Cause)

Since battery issues account for a huge percentage of breakdowns, this is the first place to start. Test your battery after 3 years, replace it before failure happens, and always keep a portable jump starter in your vehicle.

Prepare for Cold Weather

Cold weather dramatically increases failure rates, especially for batteries that are already showing signs of weakness. Keep winter emergency supplies on hand, store warm clothing (hats, gloves, jackets, blankets, etc) and other cold-weather gear in your vehicle, and ensure your battery is winter-ready.

Be Ready for Tire Issues

Flat tires remain another of the most common roadside problems. That's why it's crucial to check tire pressure regularly, keep a spare and tools, and know how to change a tire. You can also protect your tires from sun damage and dry rot by using tire covers when the vehicle is parked for extended periods.

Build a Basic Emergency Kit

A simple kit can turn a major problem into a minor inconvenience. The best emergency kit includes items and gear that match where you drive and the time of year. But even a basic emergency kit should include a flashlight, a first-aid kit, reflective triangles, road flares or traffic cones, and other basic tools.

If breakdowns are this common, and this dangerous, the real question isn’t if your car will fail… It’s whether you’ll be ready when it does.

Frequently Asked Questions About Roadside Emergencies & Vehicle Failures

How common are roadside emergencies?

Roadside emergencies are extremely common. In the U.S. alone, there are an estimated tens of millions of vehicle breakdowns each year, with millions of drivers requiring roadside assistance annually. For most drivers, experiencing at least one breakdown over time is highly likely.

What is the most common cause of a car breakdown?

The most common cause of a car breakdown is battery failure. Data consistently shows that battery-related issues account for a large percentage of roadside assistance calls, especially in colder weather. Other common causes include flat tires, engine problems, and alternator failures.

How often do car batteries fail?

Car batteries typically last 3 to 5 years, but failure can happen sooner depending on usage, climate, and maintenance. The risk of failure increases significantly after the 3-year mark, especially in extreme temperatures.

Are car breakdowns more common in winter?

Yes, car breakdowns are significantly more common in winter. Cold temperatures reduce battery performance and make it harder to start engines. In extreme cold, battery strength can drop dramatically, leading to a surge in roadside assistance calls.

What percentage of drivers are unprepared for emergencies?

A large percentage of drivers are unprepared for roadside emergencies. Many drivers do not carry essential items like jump starters, emergency kits, or even basic tools despite how common breakdowns are.

How long do drivers typically wait for roadside assistance?

Wait times for roadside assistance can vary depending on location, weather, and demand. During extreme weather events or when far from cities and municipalities, drivers may wait significantly longer, especially in rural or high-traffic areas.

What should you keep in your car for emergencies?

At minimum, drivers should carry a jump starter or jumper cables, a roadside emergency kit, a flashlight, basic tools, and warm clothing (in winter). These items can significantly reduce risk and help you handle common breakdown situations without relying entirely on roadside assistance.

Can most car breakdowns be prevented?

Yes. Most car breakdowns are preventable. The majority are caused by predictable issues like battery failure, worn tires, or lack of maintenance. Regular inspections and basic preparedness can dramatically reduce the likelihood of being stranded.

Is it safer to stay in your car during a breakdown?

In most situations, it's safer to stay inside your vehicle with your seat belt on, as seat belts can help prevent serious injuries during roadside emergencies. However, if your vehicle is in a dangerous position (such as a traffic lane), you should move to a safer location if possible to avoid injury or fatality due to secondary traffic crashes.

Why is battery failure so common?

Battery failure is common because batteries degrade over time and are highly sensitive to temperature. Many drivers also neglect testing or replacing their battery before it fails, leading to sudden breakdowns.
