Understanding Auto Component Failure and Its Role in Accident Investigations

 

 

Vehicle accidents can occur due to a variety of factors, and while driver error is often cited as the primary cause, mechanical failures also play a significant role. Determining whether an accident was caused by a defective component, wear and tear, or external forces requires specialized expertise. Garrett Forensics’ Automotive Engineers are skilled in evaluating claims related to auto component failures, providing crucial insights into accident investigations.

 

 

Common Auto Component Failures Investigated

Automobile failures can originate from numerous vehicle systems. Our experts focus on assessing key components that are often implicated in accidents:

 

1. Brakes & Braking Systems

Braking system failures can lead to severe accidents, making it essential to determine if the brakes were functioning correctly at the time of the incident. Our engineers examine:

Brake pad and rotor wear

Hydraulic system integrity

Anti-lock braking system (ABS) function

Possible manufacturing defects or recalls

 

2. Suspensions

The suspension system ensures vehicle stability, handling, and control. Failures in this system may result in loss of control, particularly at high speeds. Investigations focus on:

Shock absorbers and struts

Control arms and ball joints

Alignment issues

Structural damage from prior incidents

 

3. Tires

Tire failures are a leading cause of vehicle instability and accidents. Analyzing tire conditions can help determine:

Tread depth and wear patterns

Presence of manufacturing defects or recalls

Evidence of underinflation or overinflation

Signs of impact damage or road hazards

 

4. Engine & Powertrain

A sudden engine failure can leave a driver unable to react appropriately, leading to accidents. Our experts assess:

Fuel system integrity

Electrical and ignition system failures

Engine overheating or misfires

Oil or coolant leaks contributing to malfunctions

 

5. Transmission Issues

Transmission failures can cause unintended acceleration, loss of power, or sudden gear shifts, all of which may contribute to an accident. Our analysis includes:

Fluid levels and contamination

Clutch and gear functionality

Transmission control module (TCM) errors

Manufacturer recalls or known defects

Determining the Cause of Component Failure

 

 

Once a vehicle’s components have been thoroughly examined, our experts assess whether the failure was due to:

1. Manufacturer Defects and Recalls

Automakers issue recalls when systemic issues are found in vehicle components. If a part that failed is linked to a known defect, liability may be assigned to the manufacturer or supplier.

2. Long-Term Wear and Tear

Vehicles naturally degrade over time. In cases where lack of maintenance or extensive use contributed to a failure, insurers or owners may bear responsibility for the resulting accident.

3. Single Event Damage

A sudden impact, such as hitting a pothole or debris on the road, can cause immediate component failure. Identifying external damage helps establish whether the failure was due to a specific event rather than an inherent defect.

 

 

Why Auto Component Analysis Matters

For Insurance Claims

Understanding whether a failure was due to negligence, maintenance issues, or manufacturer defects helps insurance companies determine liability and process claims fairly.

For Legal Disputes

In cases involving lawsuits, forensic analysis of auto components provides objective evidence to support or refute claims of mechanical failure.

For Accident Prevention

Identifying patterns in component failures contributes to vehicle safety improvements, helping manufacturers address design flaws and implement necessary recalls.

 

 

Conclusion

Determining the cause of auto component failure is a crucial step in accident investigations. Whether assessing brakes, suspension, tires, engine systems, or transmissions, Garrett Forensics’ Automotive Engineers provide comprehensive evaluations that help insurers, legal teams, and vehicle owners understand the root cause of an accident. By leveraging forensic analysis, stakeholders can ensure that liability is assigned fairly and corrective measures are taken to prevent future incidents.
