From faulty airbags to unexpected acceleration, a new vehicle safety study reveals which automotive defects have been linked to the most serious consequences for drivers.
When we get behind the wheel, most of us think about traffic, road conditions, and getting to our destination safely. What we don’t always consider is whether something inside our vehicle could put us at risk.
Unfortunately, even a well-maintained car can have hidden safety defects. And according to a November 2026 vehicle safety report, some of the most dangerous problems involve parts we depend on every single day.
A new study conducted by Frankl Kominsky Injury Lawyers examined vehicle recalls and consumer safety complaints across the United States to identify which automotive defects have been associated with the greatest risks.
The findings? Faulty airbags top the list, with nearly 500 reported fatalities linked to airbag-related complaints.
But airbags aren’t the only concern. Electrical failures, unexpected acceleration, brake malfunctions, and engine problems also appear among the leading safety issues.
What the Vehicle Safety Study Revealed
Researchers examined 39 categories of automotive defects, analyzing safety recalls issued between 2015 and 2025, the number of vehicles affected, and consumer complaints involving crashes, injuries, and fatalities.
Each defect category received a risk score out of 100, with reported deaths carrying the greatest weight, followed by injuries and crashes.
One particularly interesting finding is that the most frequently recalled vehicle components aren’t necessarily the ones associated with the most severe outcomes.
For example, engine problems generated the highest number of consumer complaints, while faulty airbags were associated with the greatest number of reported deaths.
The 10 Most Dangerous Vehicle Defects
| Vehicle Defect | Risk Score | Consumer Complaints | Reported Fatalities |
|---|---|---|---|
| Airbags | 100 | 96,753 | 494 |
| Electrical System | 42 | 126,779 | 209 |
| Vehicle Speed Control | 31 | 29,384 | 267 |
| Service Brakes | 28 | 58,871 | 93 |
| Engine | 27 | 132,964 | 125 |
| Steering | 27 | 72,472 | 136 |
| Structure | 22 | 44,319 | 83 |
| Power Train | 21 | 94,648 | 41 |
| Tires | 19 | 11,689 | 249 |
| Forward Collision Avoidance | 17 | 23,795 | 130 |

1. Faulty Airbags: A Hidden Danger Behind the Steering Wheel
Airbags are designed to protect us during a collision, but what happens when that protection fails?
According to the study, airbag-related defects were associated with 494 reported fatalities and approximately 14,400 injuries.
Problems can include defective inflators, malfunctioning sensors, and airbags that fail to deploy properly during an accident.
Between 2015 and 2025, airbag-related recalls collectively affected approximately 114.1 million vehicles.
That number alone should encourage drivers to check whether their vehicles have outstanding recalls.
What drivers should know: Just because your airbag warning light isn’t illuminated doesn’t mean your vehicle is free from an active safety recall.
2. Electrical System Failures: More Than Just a Dead Battery
Most of us have experienced the frustration of a dead battery. But electrical problems can extend far beyond a vehicle refusing to start.
Modern vehicles depend on complicated electrical systems that control everything from dashboard displays to essential safety features.
The study found that electrical defects generated 126,779 consumer complaints and were associated with 209 reported fatalities.
Researchers also identified 1,535 electrical-system recalls during the study period, more than twice the number of airbag recalls.
Electrical problems can involve wiring, battery connections, electronic components, and other systems responsible for keeping a vehicle operating correctly.
What drivers should know: Repeated electrical malfunctions, unexplained warning lights, or systems that stop working unexpectedly deserve professional attention.
3. Vehicle Speed Control: When Your Car Doesn’t Respond as Expected
Imagine driving down the highway when your vehicle suddenly accelerates without warning.
It’s a frightening possibility, and one reason vehicle speed control ranks third in the study.
This category includes issues involving cruise control, acceleration, and throttle response.
Researchers identified 29,384 consumer complaints involving speed control, including reports associated with 267 fatalities, 2,336 injuries, and 4,028 crashes.
Although this category generated fewer complaints than several others, the number of serious incidents makes it especially concerning.
What drivers should know: Unexpected acceleration, unusual throttle behavior, or cruise control malfunctions should never be ignored.
4. Brake Problems: When Stopping Becomes the Problem
Your brakes are one of the most important safety systems in your vehicle.
Whether you’re navigating school pickup traffic, driving through a busy intersection, or traveling on the interstate, you need to know your vehicle will stop when you press the brake pedal.
The study placed service brake defects fourth, with 58,871 consumer complaints.
Those complaints included reports of 6,410 crashes, 3,529 injuries, and 93 fatalities.
Brake-related issues can include reduced braking performance, malfunctioning components, and systems that fail to respond as expected.
What drivers should know: Changes in brake responsiveness, unusual noises, or a brake pedal that feels different from normal should be inspected promptly. If braking becomes unreliable, stop driving the vehicle and arrange professional assistance.
5. Engine Defects: The Most Frequently Reported Problem
Engine trouble might not immediately sound as alarming as an airbag or brake failure, but it can create serious hazards on the road.
An engine that stalls unexpectedly in heavy traffic, loses power while merging, or operates unpredictably can put drivers in dangerous situations.
According to the research, engine defects generated 132,964 consumer complaints, the highest total among the categories examined.
These complaints were associated with 125 reported fatalities.
Engine problems covered in the study included unexpected stalling, unreliable performance, and other operational failures.
What drivers should know: Repeated stalling, unexpected power loss, or unusual engine behavior should be investigated rather than dismissed as a minor inconvenience.
Why Vehicle Recalls Matter More Than You Think
Let’s face it. Life gets busy.
Between work, family responsibilities, errands, and everything else on our calendars, a vehicle recall notice can easily become another piece of mail we intend to deal with later.
But putting off a recall repair could mean continuing to drive with a known safety issue.
Steven L. Frankl of Frankl Kominsky Injury Lawyers emphasized the importance of taking recalls seriously, explaining that drivers often don’t realize a component is defective until something goes wrong.
His advice is straightforward: pay attention to recall notices, document unusual vehicle behavior, report safety concerns, and have potential problems inspected.
And here’s something worth remembering: A safety recall repair is generally performed free of charge at an authorized dealership. Some exceptions can apply, particularly to older recalls or vehicles.
Five Simple Ways to Protect Yourself From Vehicle Defects
You don’t have to be a mechanic or automotive expert to take a proactive approach to vehicle safety.
Here are five practical steps every vehicle owner can take:
- Check your vehicle for open recalls. Visit NHTSA’s official recall lookup and enter your vehicle identification number (VIN) to see whether any unrepaired safety recalls are listed.
- Don’t ignore dashboard warning lights. While some warnings indicate minor issues, others could point to problems affecting your vehicle’s safety or performance.
- Keep up with regular maintenance. Routine inspections can help identify developing mechanical problems, although maintenance alone cannot prevent manufacturing defects.
- Report unexpected vehicle problems. If you experience a safety-related issue, you can submit a complaint through the National Highway Traffic Safety Administration. Consumer reports help regulators identify possible patterns of defects.
- Schedule recall repairs promptly. If your vehicle has an outstanding safety recall, contact an authorized dealership to arrange the necessary repair. Ask about transportation options if parts aren’t immediately available.
