How Auto Mechanics Can Be Held Liable for Negligence in Accidents

While driver errors may be the most common cause of accidents, auto mechanic negligence can also make your repair shop or technician liable. Learn how an auto mechanic can be held liable for a car accident and how Jacob Emrani accident attorneys can help you file a mechanic negligence lawsuit in California and pursue fair compensation with key evidence.

Can an Auto Mechanic Be Held Liable for a Car Accident?

An auto mechanic can be held liable for a car accident if the incident directly resulted from substandard repairs, maintenance, or hazard warnings. When they accept a vehicle for service, repair shops have a legal duty of care to ensure the vehicle is safe to operate. Negligence breaches that duty and may result in a car accident.

What Is Auto Mechanic Negligence?

Auto mechanic negligence occurs when a mechanic, technician, or repair shop fails to provide a reasonable standard of care under normal circumstances, and the substandard work leads to a faulty brake repair accident or another collision that causes damage or personal harm.

What Types of Faulty Repairs Can Cause an Accident?

Different types of faulty repairs may cause an accident:

  • Misdiagnosis: Failing to accurately diagnose a hazardous problem.
  • Substandard parts: Using defective, incorrect, or recalled parts to complete a repair.
  • Incorrect repairs: Installing parts incorrectly.
  • Fraudulent services: Falsely claiming to have completed repairs or part installations.
  • Illegal modifications: Unsafe vehicle modifications, such as lowered or lifted suspension, excessively dark window tints, or non-compliant lighting.

How Do You Prove a Mechanic Was Negligent?

Proving that a mechanic was negligent requires you to demonstrate four elements:

  • Duty of care: The mechanic had a legal duty to repair or service your car correctly and safely.
  • Breach of duty: The mechanic failed to meet reasonable repair or service standards.
  • Causation: The mechanical failure and accident occurred as a direct result of the mechanic’s services.
  • Damages: You suffered losses or damages as a result of the accident.

Can the Auto Repair Shop Be Liable for an Employee’s Mistake?

An auto repair shop may be liable for an employee’s mistake if you’re in an accident resulting from an error in your vehicle’s repairs or services. Under the legal doctrine of respondeat superior in California, employers are responsible for certain employee actions if the mistake occurred while the employee was performing normal job duties.

What If a Defective Auto Part Caused the Accident?

If a defective auto part caused the accident, liability may instead fall on the vehicle or part manufacturer, distributor, or supplier. Under product liability claims, these parties have a duty to ensure that products are safe when used as intended. Different types of defects may contribute to accidents:

  • Manufacturing defects: An error during production made the part unsafe or different from its intended design.
  • Design defects: The part’s design is inherently unsafe, even when produced correctly.
  • Failure-to-warn defects: The responsible party failed to provide clear instructions or warnings about non-obvious risks or proper usage.

Can Multiple Parties Be Responsible for the Same Accident?

Multiple parties may be responsible for the same accident. California establishes fault using a comparative negligence rule, so more than one party can be liable. That may include:

  • The mechanic or technician who completed the work.
  • The auto repair shop.
  • Parts manufacturers or suppliers.
  • Drivers.

What Evidence Should Be Preserved After a Suspected Faulty Repair Accident?

After a car accident caused by faulty repairs, you should preserve any evidence that indicates the cause or describes the accident and the specific mechanical failure:

  • Failed or broken parts, such as a failed brake line, incorrectly installed tie rods, or worn brake pads.
  • Repair invoices and work orders that describe the services completed in detail.
  • Maintenance invoices or records documenting consistent service and vehicle value before the faulty repair.
  • All communication exchanged with the auto repair shop and its employees.
  • Photographs and videos of the accident and failed parts, including dashcam footage.
  • Official police or accident reports.
  • Inspections and reports from forensic mechanics or accident reconstruction specialists.
  • Witness statements from passengers, other drivers, and repair shop employees.
  • Medical records and receipts related to the accident.

What Compensation May Be Available After an Accident Caused by Negligent Repairs?

You may be able to claim both economic and non-economic damages after an accident caused by negligent repairs, depending on the circumstances. These include:

  • Vehicle repair and property damage: The cost to repair or replace your vehicle or replace personal property damaged in the accident.
  • Lost wages: Income you were unable to earn while recovering from the accident, as well as compensation if the accident reduced your long-term earning capacity.
  • Medical bills: Immediate and long-term medical and rehabilitation needs due to the accident, including emergency medical services, hospital stays, follow-up doctor visits, and physical therapy.
  • Pain and suffering: Physical discomfort and pain experienced as a result of the accident.
  • Emotional distress: Depression, anxiety, post-traumatic stress disorder, or other emotional distress or mental health conditions resulting from the accident.
  • Disfigurement or scarring: Lasting or permanent scarring or disfigurement.

What Should You Do If You Suspect a Mechanic Caused Your Accident?

If you suspect that a mechanic caused your accident through substandard services or repairs, follow these steps:

  1. Check for injuries and call for help. Immediately after the accident, move to safety and call emergency services, even if you don’t notice injuries. Some problems may only appear hours or days after the accident.
  2. Exchange information. Get contact and insurance information from other drivers and contact details from witnesses.
  3. Document the scene. Take photos or videos of the vehicle, failed parts, and driving conditions.
  4. Preserve the vehicle. Have your vehicle towed to a secure location, and don’t repair or alter it right away.
  5. Notify your insurer and seek legal counsel. Report the collision and speak with an attorney about preserving evidence and protecting your rights.
