Aftermarket Auto Part Defect Lawsuit
Defective Aftermarket Parts Attorney
Investigating dangerous modified vehicles and defective aftermarket auto components
If you’ve been injured in an accident caused by defective modified aftermarket auto parts, filing a lawsuit could be a critical step toward justice and recovery. The rise in aftermarket modifications—such as custom exhausts, suspension kits, or performance chips—has led to an increase in safety concerns, with the National Highway Traffic Safety Administration (NHTSA) reporting over 1,000 complaints annually related to aftermarket failures.
The increase in accidents caused by defective aftermarket auto parts has fueled a surge in lawsuits across the United States. Defective aftermarket parts can lead to catastrophic accidents, causing injuries, property damage, and even fatalities. Lawsuits offer a pathway to recover compensation for medical bills, lost wages, and pain and suffering.
Top Aftermarket Part Defects and Recalls
- Faulty Airbags: Aftermarket airbags, often cheaper alternatives to OEM versions, have been recalled for failing to deploy or deploying unexpectedly. A notable 2022 recall involved 50,000 units due to improper inflation mechanisms, linked to multiple crashes.
- Defective Brakes: Substandard brake pads or rotors have caused braking malfunctions, with a 2021 recall affecting 30,000 vehicles. These parts, made with inferior materials, increase stopping distances, leading to rear-end collisions.
- Suspension Failures: Aftermarket suspension kits, popular for lowering vehicles, have been recalled for structural weaknesses. A 2023 recall covered 20,000 kits after reports of rollaway accidents due to poor design.
- Faulty Fuel Systems: Modified fuel lines or pumps have sparked recalls, such as a 2020 case involving 15,000 units where leaks caused fires. These defects often stem from untested materials.
- Defective Software: Performance chips altering engine software have been recalled for causing unintended acceleration. A 2024 recall targeted 10,000 chips after software glitches led to crashes.
Consumer safety advocates are warning that modified vehicles are threatening motorists and overall road safety. American roadways are filled with modified vehicles and aftermarket auto products that have not been properly tested for road and collision worthiness.

- Does this aftermarket vehicle or modified vehicle comply with the Federal Motor Vehicle Safety Standards?
- Has a certified automotive engineer reviewed these vehicle design modifications?
- Have these modified vehicles been equipped with safety features and crash tested?

Why File a Lawsuit?
