North Carolina Auto Repair Law

Educational summary only – not legal advice.

North Carolina Motor Vehicle Repair Act (N.C. Gen. Stat. §20‑354 et seq.)

This law applies to most motor vehicle repairs performed for compensation in North Carolina and establishes mandatory consumer protections when repair costs exceed certain thresholds.

Key Dollar Thresholds

·       $350 threshold: If the total cost of repairs is expected to exceed $350, the repair shop must provide a written estimate unless the customer signs a written waiver.

·       Repairs costing $350 or less do not require a written estimate.

Authorization Requirements

·       Repair work exceeding $350 cannot begin without customer authorization.

·       Authorization may be written or oral, but written authorization is required when waiving a written estimate.

·       Diagnostic or teardown charges must be disclosed and authorized before being incurred.

Over‑Estimate Rules

·       If final charges will exceed the written estimate by more than 10%, the shop must contact the customer and obtain approval before continuing.

·       Additional authorization must be documented.

Disclosure Timing

·       Required disclosures must be made before work begins, including:

o   Estimated cost

o   Diagnostic fees

o   Storage charges

o   Parts return rights

·       If an estimate cannot be prepared until after diagnostics, authorization is required before further repairs.

Parts Return Rules

·       Customers have the right to inspect or receive replaced parts if requested at the time of authorization.

·       Parts may be retained by the shop only if returned to a supplier under a warranty or exchange program.

·       If the customer does not claim parts within two business days, the shop may dispose of them.

Invoice Requirements

·       Shops must provide a final itemized invoice showing:

o   Parts (new, used, rebuilt clearly identified)

o   Labor charges

o   All authorized additional work

Record Retention

·       State law does not specify a record retention period.

·       General consumer protection and standard business record‑keeping practices apply.

Enforcement & Consequences

·       Charging for unauthorized work is unlawful.

·       Consumers may sue for damages, court costs, and attorney’s fees.

·       Violations may also constitute unfair or deceptive trade practices.

·       Complaints may be filed with the North Carolina Attorney General’s Consumer Protection Division.

What This Means for Consumers

·       You have the right to know repair costs in advance for major repairs.

·       You cannot be charged more than 10% above an estimate without approval.

·       You may inspect or receive replaced parts if you ask up front.

·       Unauthorized charges can be disputed in court or through the Attorney General.

What This Means for Repair Shops

·       Written estimates and clear authorizations are mandatory for repairs over $350.

·       You must stop work and contact the customer if costs exceed the estimate by more than 10%.

·       Signs explaining customer rights must be prominently displayed.

·       Poor documentation or unauthorized work exposes the shop to lawsuits, penalties, and regulatory complaints.

Bottom Line

If you run a repair shop in North Carolina, strict estimate and authorization compliance is essential. If you are a consumer, the law gives you strong tools to prevent surprise charges and deceptive practices.
