Unauthorized Use or Theft? Tennessee Woman Sues Dealership After Employee Allegedly Took Vehicle Without Consent

A Tennessee woman has initiated civil proceedings against a car dealership and one of its employees following an incident that has raised legal questions around unauthorized use of property, employer liability, and consumer protection.

Kimberly Porter alleges that her Mercedes-Benz C300 AMG was taken without her consent while it was in the custody of a dealership for repairs. According to her account, the incident came to light on January 16 when she began receiving GPS alerts indicating that the vehicle was being driven.

After initially suspecting a system error, Porter said she tracked the vehicle’s location using the onboard system and drove to the site in a loaner car provided by the dealership. She reportedly found her vehicle parked at a local establishment and contacted law enforcement.

Responding officers discovered an item of clothing inside the vehicle that did not belong to Porter. Identification recovered from the item led to Derrick Nguyen, a dealership employee, who was later arrested and charged with theft of property.

Nguyen allegedly claimed he had permission to use the vehicle, a claim that authorities have since disputed.

The dispute has since expanded into civil litigation. Porter has filed a lawsuit against both Nguyen and the dealership, alleging unauthorized use of her vehicle and seeking damages. The complaint also raises concerns about the dealership’s conduct following the incident.

According to Porter, dealership representatives attempted to pressure her into dropping the criminal complaint. She further alleges that she was instructed to retrieve her vehicle immediately or risk having the loaner car reported as stolen—an assertion that, if substantiated, could carry legal implications related to coercion or unfair business practices.

From a legal perspective, the case may engage principles of bailment law, under which a business entrusted with a customer’s property owes a duty of care to safeguard it and prevent unauthorized use. A breach of that duty could expose the dealership to liability, particularly if the employee’s actions are found to have occurred within the scope of employment or due to negligent supervision.

Additionally, the alleged conduct may support claims of conversion—defined as the unauthorized exercise of control over another’s property—as well as potential violations of state consumer protection statutes.

The criminal proceedings against Nguyen will address the question of individual culpability, while the civil case is expected to examine broader issues of institutional responsibility and damages.

The incident also highlights the evidentiary role of vehicle tracking technology in modern disputes involving property misuse, providing real-time data that can substantiate claims of unauthorized activity.

As litigation progresses, the case may offer further clarity on the legal obligations of automotive service providers and the remedies available to consumers when those obligations are breached.
