Know your rights when a faulty part causes a crash.

If a faulty vehicle part caused or worsened your crash, you may be able to sue the manufacturer, distributor, or seller. These cases fall under product liability law. You do not need to prove the company was careless; the defect itself may be enough to establish liability.

What Do You Need to Prove in a Defective Car Part Case?

To bring a successful claim, you must establish three core elements. Each one requires clear evidence, not speculation.

The Part Was Defective

You must show that the part had a flaw when it left the manufacturer. This is not about wear and tear or misuse. The defect must be something that made the part unsafe under normal conditions.

The Defect Caused Your Accident

This is called causation, and it is often the hardest part to prove. You must show a direct link between the defect and the crash. Simply having a faulty part present is not enough. A professional must explain how that specific flaw led to the accident.

You Suffered Real Damages

Your injuries and losses must be tied to the defect. Medical bills, lost wages, and pain and suffering all count. The damages must stem from the defective part, not just from the crash in general.

What Happens When a Defective Car Part Causes an Accident?

A defective car part claim is different from a standard accident case. In a typical car accident, one driver’s negligence is the cause. In a defective part case, the product itself is what failed, and the company that made or sold it may be responsible.

Defects fall into three categories. A design defect means the part was unsafe from the start. A manufacturing defect means something went wrong during production. Failure to warn means the company did not provide proper safety instructions regarding a known risk.

Common examples include faulty brakes, steering failures, tire blowouts, weak welds, and airbag malfunctions. The defect must have existed before the accident. Damage that happened during the crash itself does not count.

Vermont and New Hampshire both recognize product liability claims for defective auto parts. Under strict liability, you do not have to prove the manufacturer knew about the problem. You only need to show that the part was defective, it caused your accident, and you were harmed.

Who Can Be Held Responsible for a Defective Car Part?

More than one party may share liability in a defective part case. The right defendants depend on where the defect originated.

  • The car manufacturer, if the defect came from the vehicle’s original design or assembly
  • The parts supplier, if a specific component was faulty before it was installed
  • The dealer or retailer, if they sold the vehicle knowing about a defect
  • A prior owner, in some cases, if they failed to disclose a known safety issue

You can also pursue claims against both the at-fault driver and the manufacturer at the same time. These are separate legal theories. A driver can be negligent, and a part can be defective; both can contribute to the same crash.

What Evidence Supports a Defective Car Part Claim?

Building a strong case means gathering the right evidence early. Some of it can be lost or destroyed if you wait too long.

Professional Analysis

Engineers and accident reconstruction professionals can examine the failed part. They identify the type of defect, when it occurred, and how it caused the crash. Their reports are often the most important evidence in these cases.

Physical Evidence and Records

Preserve the damaged part and the vehicle if possible. Accident scene photos, maintenance records, and the vehicle’s service history all help show that the defect existed before the crash. Police reports and medical records tie the accident to your injuries.

NHTSA Recall Information

The National Highway Traffic Safety Administration tracks recalls and safety complaints. If your part was subject to a recall or had prior complaints, that information strengthens your claim. It shows the manufacturer had reason to know about the problem.

How Vermont and New Hampshire Handle These Claims

Both states recognize strict product liability for defective auto parts. This means you do not need to show that the manufacturer was careless. You only need to prove the part was defective and caused your harm.

The statute of limitations in both Vermont and New Hampshire is generally three years. This clock starts from the accident date. Waiting too long can bar your claim entirely, even if the evidence is strong.

Acting early matters. Evidence degrades, parts get lost, and witnesses’ memories fade. The sooner a product liability attorney at Sabbeth Law can review your case, the better your chances of preserving what you need.

Should You Get Legal Guidance?

Defective car part cases are more complex than standard accident claims. They involve product liability law, professional analysis, and often multiple defendants. If you think a faulty part played a role in your crash, getting a legal opinion early can help you understand whether you have a viable claim.

A lawyer with experience in product liability can review the facts, identify the right defendants, and explain what evidence you will need. They can also advise on how Vermont or New Hampshire law applies to your specific situation.

You do not need to have everything figured out before reaching out. Many people are simply unsure whether the part failure and the accident are connected. A legal review can answer that question and help you decide on your next steps.

FAQs

What types of car part defects can form the basis of a lawsuit?

Any part that fails to work as intended and contributes to a crash may support a claim. Common examples include brake failures, steering defects, tire blowouts from manufacturing flaws, airbag malfunctions, and suspension problems. 

Can I sue both the driver and the car manufacturer?

Yes. You may pursue claims against multiple parties in the same case. The at-fault driver remains liable for negligence, while the manufacturer may be liable under product liability law.

How do I prove a car part was defective and not just damaged in the crash?

Mechanics, engineers, or accident reconstruction professionals can examine the failed part and compare the damage pattern to known manufacturing defects. Recall data from the NHTSA, photos taken right after the accident, and the vehicle’s service history all help show that the defect was present before the crash occurred.

Do Vermont and New Hampshire recognize strict liability for defective auto parts?

Yes. Both states recognize strict product liability. Under this standard, a manufacturer is liable for a defective part regardless of whether the company was negligent. You must show that the part was defective, it caused your injury, and you were using it properly. You do not need to prove the manufacturer knew about the defect or failed to inspect it.

What damages can I recover in a defective car part accident claim?

Recoverable damages may include medical expenses, lost wages, pain and suffering, and property damage. In serious cases, damages can extend to long-term care costs, lost earning capacity, and loss of consortium. Punitive damages may be awarded if the manufacturer acted with gross negligence or deliberately disregarded safety.
