This is the complete record of Ethical Mechanic's investigation into Nicholas Mazerac — who operates as "Nick Maz" — his wife Sammy Mazerac, and the online following that closed ranks around their Colorado Springs mobile-mechanic operation.
Every event described here is drawn from a first-hand customer account, direct correspondence between the parties and Ethical Mechanic, public evidence, and witness statements gathered over the course of the investigation. We have laid it out in the order it happened, because the order is the point: this is not a single bad repair. It is a documented sequence — a scam, a refusal to make it right, and then a campaign of intimidation aimed at the people who refused to look away.
July 2023 — It Started With $300 and Two Torn-Apart Vehicles
The investigation began with a phone call. A distressed customer contacted Ethical Mechanic to describe what had happened after he hired Nick Mazerac — advertising a business called "Colorado Mobile Mechanic" — to work on his vehicles, among them a Bronco and a work truck.
By the customer's account, Nick never completed a single repair. He left both vehicles torn apart, with parts scattered, and the customer roughly $300 out of pocket. His trucks were now in worse condition than before any "mechanic" touched them — undrivable, disassembled, and stripped.
Nick promised to come back and finish the job. Instead, he went quiet — dodging the customer's calls and text messages for more than two weeks. Left with no working vehicle, no refund, and no contact, the customer did the only thing left to do: he filed a police report, hoping to recover his missing axles and see the mechanic held accountable.
That could have been the end of it — one complaint, one report. But Nick Mazerac is not an anonymous figure working out of a parking lot. He runs a Facebook group, "Mobile Mechanics of Northern Colorado," with more than 1,200 members. An operation with that kind of reach, and that kind of track record, was not going to be a one-victim story. Ethical Mechanic began collecting evidence.
The Confrontation — and an Admission
When Ethical Mechanic published the customer's account, Sammy Mazerac — Nick's wife — stepped forward to defend her husband. She insisted the accusations were baseless. She argued that Nick does not run a formal business at all, but operates on what she called a "mutual agreement basis."
In the course of defending him, she confirmed the single most important fact in this entire case. By Sammy Mazerac's own admission, Nick Mazerac holds:
- No legitimate business license
- No valid ASE certification
- No liability insurance
This is not a technicality. Those three things are the floor — the bare legal and safety minimum — for anyone who is paid to work on the vehicles that carry families down a highway. "Mutual agreement" is not a substitute for any of them. It is simply a phrase used to describe taking money for work while accepting none of the responsibility that comes with it.
Ethical Mechanic pressed for proof to support the Mazeracs' claims. What came back was not proof. It was friction — accusations, denials, and a rising temperature on both sides.
The Resolution That Was Refused
Ethical Mechanic does not exist to punish people. It exists to resolve problems and warn the public. So a resolution was put on the table — a genuine off-ramp.
The offer was straightforward: Ethical Mechanic would remove the published story and issue an apology if a few reasonable conditions were met:
- Arrange a supervised exchange at a police station so the customer's belongings could be returned safely.
- Delete the Facebook posts that the Mazeracs and their group had aimed at Ethical Mechanic.
- Allow Ethical Mechanic spectator-only access to observe the mobile-mechanic group, purely for transparency.
Sammy Mazerac declined. Her stated reason was that she had no control over her husband's Facebook group. She said she would drop the disputed property at a police station, and considered the matter closed.
It was not closed. A customer was still out his money and his vehicles. And rather than a resolution, what followed was a campaign.
The Risk Nick Maz Puts on Every Customer
Before going further, it is worth being blunt about what hiring an operator like Nick Mazerac actually means — because his defenders treated the missing license, certification, and insurance as paperwork nitpicking. They are not.
Picture the realistic failure cases. An uncertified mechanic botches a brake repair, and the customer discovers it at 60 miles per hour with their family in the car. An untrained hand runs an electrical diagnostic, and the vehicle catches fire — a total loss, with no insurance behind the person who caused it.
Liability insurance exists precisely so that when something goes wrong, the customer is not left holding the entire loss. By choosing to operate without it, Nick Mazerac does not eliminate that risk — he simply transfers all of it onto the customer and onto whoever happens to be a passenger in that vehicle. That is the trade every "mutual agreement" customer is unknowingly signing.
More Victims — and a Pattern of Criminal Conduct
As word of the investigation spread, more victims came forward. What had looked like a single complaint resolved into a pattern — the same operation, the same missing credentials, the same outcomes, told by different people who had never met.
Ethical Mechanic's assessment is direct: Nick Mazerac sits at the heart of what amounts to an ongoing criminal endeavor within the auto-repair industry — taking payment for work he is not licensed, certified, or insured to perform, and then failing to deliver it. The conduct documented here raises exactly the issues that Colorado's Motor Vehicle Repair Act (C.R.S. 42-9-101 through 113) was written to address.
Sammy Mazerac's role is not incidental. Throughout the investigation she functioned as the operation's shield — defending the indefensible, asserting things she could not support, and avoiding the questions she could not answer. The two of them, together, kept the operation running.
The Campaign — Threats, a "Cult," and a Fake Identity
Here is the tell that matters most. When a complaint is false, the simplest response on earth is evidence — a receipt, a finished job, a satisfied customer. When the response is instead a coordinated campaign of intimidation, it is worth asking why.
That is exactly what Ethical Mechanic was met with.
The group. Nick Mazerac's 1,200-member Facebook following did not demand answers from him. It closed ranks around him. Members were willing to stake their own reputations to shield an alleged scammer — behavior Ethical Mechanic described, accurately, as cult-like: a level of devotion entirely disconnected from the facts in front of them.
Keon Moore. During the investigation, Ethical Mechanic made contact with Keon Moore, an individual associated with Nick Maz who appears to offer his own unlicensed auto-repair services. A routine outreach call turned into a chilling encounter — Moore responded with open, violent threats. His reaction is documented in full in our separate report, Beware: Keon Moore — Threats, Intimidation, and a Troubling Association (case file: /scammer/keon-moore). The willingness to send a violent associate to threaten investigators tells you what the Mazerac operation is prepared to do to protect itself.
Santasha Beluche. When an Ethical Mechanic staff member contacted members of Nick's group simply to warn them, one defender — Santasha Beluche, a Denver-area emergency-room nurse — responded with hostility, calling our staff an "ass." We blocked the account. She then began spreading falsehoods, claiming Ethical Mechanic lacks experience in the auto-repair and mobile-mechanic industries — a claim that is itself untrue. When we attempted to correct the record, she escalated: mocking our staff, publicly and falsely accusing Ethical Mechanic of making threats, and finally stating outright that she was "making this personal." A medical professional is expected to rise above this kind of conduct. Ethical Mechanic's position is that Denver Health should be made aware of her behavior, and we have moved to file complaints regarding it. This was never a personal matter for us — Beluche is not a mechanic and has no bearing on our work — but a witness statement is a witness statement, and her conduct is part of the record.
"Charles Mallan." In August 2023, the Mazeracs publicly accused Ethical Mechanic of creating Facebook pages and GoFundMe accounts in their name. We did not, and we said so plainly. Around the same time, a person calling himself "Charles Mallan" contacted Ethical Mechanic through our website's chat — using the address charlesmallan45@gmail.com. "Charles Mallan" is a name unknown to anyone involved. Our firm position: "Charles Mallan" is not a real, independent third party. We believe that contact traces directly back to the Mazeracs themselves — a fake identity created to manufacture the very "harassment" they were publicly complaining about.
Every one of these moves had the same effect, and likely the same purpose: to drag attention away from the customer who was still out his money and his vehicles, and to exhaust the people asking about him. None of it answered the original complaint. None of it ever could.
The Children
The most serious dimension of this case is not the money. It is the home that two children are growing up in.
Ethical Mechanic does not raise this lightly, and we raise it because the welfare of children overrides our discomfort in discussing it. Across our direct dealings with the Mazeracs, Sammy Mazerac appeared genuinely unstable — her emotional state, in the presence of a newborn, was unpredictable and difficult to follow. We urged her, in plain terms, to seek counseling and professional support; coping with motherhood is hard enough without the rest of this, and there is no shame in getting help.
There is more, and the public record demands we state it. In the course of the investigation, Ethical Mechanic came upon information indicating that Sammy Mazerac reportedly witnessed a gruesome murder as a child. A trauma of that magnitude can affect anyone — that is not an accusation, it is a recognition. But combined with everything else documented here, it deepened our concern for the children in that household.
That concern is concrete. Children raised inside an operation built on deception — taught, by example, that you take people's money and lie your way out of the consequences — are children being set on a path. The risk is that today's household lesson becomes tomorrow's adult pattern.
For those reasons, Ethical Mechanic took action on the children's behalf. We reached out to the Colorado Department of Human Services, and we have urged the city of Colorado Springs, El Paso County, and the State of Colorado to act in the best interest of these children — including that an immediate welfare investigation, and potentially removal from the household, be seriously considered. That is not a sentence we write casually. We write it because no one else in that 1,200-member group will.
What Ethical Mechanic Has Done
This investigation has never been about winning an argument on Facebook. From the start, the goal was a resolution and, failing that, accountability through the proper channels.
When the Mazeracs refused every reasonable path, Ethical Mechanic escalated the matter to the authorities equipped to handle it. We have brought this case to:
- The Colorado Department of Human Services — regarding the welfare of the children.
- The Colorado Attorney General's office and the District Attorney's office — regarding the alleged fraud and unlicensed operation.
- The Colorado Labor Commission.
- The Office of Policy Research & Regulatory Reform — regarding stronger guardrails for the mobile-mechanic industry as a whole.
We presented the facts as they are. Some people accepted them. Others chose the comfort of denial. The facts did not change either way.
The Bottom Line
Strip away the noise — the group, the threats, the fake email address, the theatrics — and what remains is brutally simple.
A man with no license, no insurance, and no certification took a customer's money, destroyed two of his vehicles, and never made it right. When he was asked about it, his answer was not evidence. It was a campaign — to intimidate, to distract, and to bury the story under enough drama that people would stop asking.
Ethical Mechanic did not stop asking. Nick Mazerac is, in our documented assessment, a fraud and a disgrace to a trade that thousands of honest mechanics work hard to protect — and a man whose conduct, as a businessman and as a father, his own community should be alarmed by rather than defending. We believe his actions warrant criminal scrutiny, and we will continue to support every victim who comes forward.
If you have done business with Nick Maz, Nick Mazerac, or "Colorado Mobile Mechanic" — or if you have information about this operation — contact us. Every account is handled responsibly, and every account strengthens the record.
Before you ever hand a vehicle, a payment, or your family's safety to a mobile mechanic, confirm three things in writing: a business license, liability insurance, and a verifiable certification. An operator who cannot produce them — and who answers a simple question with hostility — has already told you everything you need to know.
