A Mercedes-Benz customer thought her car was safely parked at a dealership for repairs. Instead, it was being driven across town, stopping at restaurants and bars late into the night. What followed wasn’t just an arrest—it’s turning into a legal fight that raises serious questions about trust, accountability, and what really happens to your car after you hand over the keys.
For anyone who’s ever dropped off a vehicle at a dealership and walked away without a second thought, this story hits uncomfortably close to home.
The Night Everything Went Sideways
Kimberly Porter had a long history with the brand. She wasn’t just a casual owner—she had owned multiple Mercedes vehicles and clearly cared about maintaining them properly. When her C300 AMG started having issues after what she described as bad fuel, she did what most drivers would do: she had it towed to the dealership.
The car arrived at Mercedes-Benz of Collierville in December. Weeks passed, and by mid-January, it was still in the shop. Then came the moment that changed everything.
One evening, Porter received a notification from her GPS tracker showing her car was moving. At first, she questioned whether it was a glitch. Then another alert came through, and this time it was harder to ignore.
The car wasn’t just being moved around the lot. It was traveling across town.
Tracking a Car That Shouldn’t Be Moving
The GPS data told a clear story. Porter’s vehicle was last recorded near the dealership just before 6 p.m. A couple of hours later, it appeared in a different part of the city. Then it showed up outside a restaurant.
Later that night, another location ping placed the car at a bar. That’s when Porter decided to act.
She got into her loaner vehicle and drove to the location herself. What she found confirmed her worst suspicion—her car was sitting in the parking lot, far from where it should have been.
At that point, it looked like theft. But what happened next made the situation even more shocking.
From Suspected Theft to Arrest
After unlocking her car with a spare key, Porter contacted police. When officers arrived, they searched the vehicle and found items inside that didn’t belong to her, including a coat containing identification.
That discovery quickly shifted the investigation. Officers recognized the individual connected to the ID as someone associated with the dealership.
Instead of chasing an unknown thief, police were now dealing with the possibility that the car had been taken by someone who worked there.
Authorities eventually brought the employee out in handcuffs. The individual, identified as Derrick Nguyen, was taken into custody and later charged with theft of property.
A Dangerous Situation Behind the Wheel
The situation didn’t stop at unauthorized use of the vehicle. According to court records, Nguyen had been drinking before being taken into custody.
That detail raises the stakes significantly. This wasn’t just someone taking a customer’s car without permission—it involved a vehicle being driven while the driver was under the influence.
For any car owner, that’s the nightmare scenario. It’s not just about mileage or misuse—it’s about liability, safety, and what could have happened if things had gone wrong on the road.
Porter herself raised that concern, pointing out the potential consequences if there had been a crash or worse.
Dealership Response Adds Fuel to the Fire
If the incident itself wasn’t enough, what happened next only deepened the conflict. The following day, Porter says the dealership contacted her and told her the car was ready for pickup and that she needed to return the loaner vehicle quickly.
At the same time, she says she was asked to drop the charges against the employee. That request didn’t sit well, especially given what had just happened.
Porter also questioned how the situation could occur in the first place. According to her account, dealership leadership suggested that technicians are authorized to drive customer vehicles for diagnostic purposes.
That explanation might apply to short test drives. It becomes far harder to justify when a vehicle is being driven across multiple locations over several hours, including stops at bars.
The Legal Fight Begins
The criminal case is only part of the story. Porter has also filed a civil lawsuit against both Nguyen and the dealership.
Her attorney has raised concerns that this may not be an isolated incident. The argument centers on whether the dealership’s response reflects a broader issue with how customer vehicles are handled behind the scenes.
The case now moves into federal court, where the details of dealership policy, employee conduct, and customer rights will be examined more closely.
Meanwhile, a dealership representative has declined to provide further comment, citing the ongoing nature of the case.
Why This Hits Every Car Owner
For enthusiasts and everyday drivers alike, this story cuts straight to a core assumption: that your car is safe when it’s in professional hands.
Dealerships and service centers rely heavily on trust. Customers hand over keys, often without thinking twice, expecting that their vehicles will be used only for legitimate purposes.
Incidents like this challenge that trust. They force drivers to reconsider how much oversight exists once a car disappears into a service bay.
It also raises practical questions. Should owners be setting stricter limits? Should dealerships be more transparent about who has access to vehicles and when they’re being driven?
The Bigger Issue Behind the Headlines
This case highlights a broader tension in the automotive world—one that doesn’t get much attention until something goes wrong. As vehicles become more valuable and more connected, the risks tied to unauthorized use grow larger.
Technology like GPS tracking is giving owners more visibility, but it’s also exposing behavior that might have gone unnoticed in the past.
At the same time, dealerships are under pressure to balance operational flexibility with accountability. When that balance fails, the consequences can escalate quickly, both legally and publicly.
What This Situation Really Reveals
At its core, this isn’t just about one employee or one dealership. It’s about the fragile relationship between drivers and the businesses they trust with their vehicles.
When that trust breaks, it doesn’t just affect one customer—it sends a message to everyone paying attention.
The bigger question now is simple but uncomfortable: if this could happen once, how often does it happen without anyone knowing?
