A car crash can happen even when you drive carefully. A failed brake, defective tire or broken steering component may cause a collision without warning. If a vehicle part caused your crash, you may wonder whether you can hold the manufacturer responsible. In New Jersey, the answer may depend on the defect, how it caused the crash and the injuries you suffered.
How defective car parts cause crashes
Vehicle defects can affect a driver’s ability to control a car. Examples include:
- Brakes that fail to stop the vehicle
- Tires that suddenly lose pressure or separate
- Steering components that break or malfunction
- Airbags or seat belts that fail during a collision
A defect may exist because of a design problem, a manufacturing error or inadequate safety warnings.
When a manufacturer may be liable
Under New Jersey product liability law, a manufacturer or other responsible business may face liability when a defective product causes an injury. The injured person generally must show that the product was defective and that the defect caused the harm. New Jersey law recognizes claims involving manufacturing defects, defective designs and inadequate warnings or instructions.
A mechanic’s mistake or poor maintenance may also contribute to a crash. In that situation, responsibility may involve a repair shop, parts supplier or another party rather than the vehicle manufacturer alone.
Evidence that can support a claim
Investigators need to determine whether a defective part caused the crash. Useful evidence may include:
- The vehicle and damaged components
- Maintenance and repair records
- Recall notices and service bulletins
- Accident reports and photographs
- Professional inspection of the failed part
Avoid discarding or repairing a potentially defective component before investigators can examine it. Preserving evidence can help establish what happened.
Time limits and case complexity in product liability claims
New Jersey generally imposes a two-year statute of limitations on personal injury claims, although the specific deadline and when the claim begins to accrue can depend on the circumstances. Product liability cases can also involve technical evidence and several potentially responsible parties.
A defective car part may provide a legal basis for a claim even when another driver was not at fault. Understanding the defect and preserving evidence can help crash victims make informed decisions about their options.
