TL;DR
According to the EPA, Wehrli Custom Fabrication, Inc. prioritized private profit over our air quality of the general public by manufacturing, selling, and installing nearly 1,500 “defeat devices.”
These components were designed specifically to bypass federal emission controls on heavy-duty diesel engines, effectively turning vehicles into mobile sources of unregulated pollution.
While the pollution-enjoying company has agreed to a financial settlement, the systemic nature of this conduct suggests a broader disregard for corporate social responsibility in favor of short-term economic gain.
Please continue reading to uncover the specific timeline of these actions and why this case serves as a chilling example of how neoliberal capitalism can compromise the very air we breathe.

The Machinery of Corporate Greed
In the logic of our modern marketplace hellscape, “efficiency” is often a code word for cutting corners. For Wehrli Custom Fabrication, this took the form of “tampering”…the act of removing or rendering inoperative the emission control systems that protect the public from toxic exhaust.
These systems, including Diesel Particulate Filters (DPFs) and Selective Catalytic Reduction (SCRs), are not optional “extras”; they are the primary defense against nitrogen oxides and particulate matter.
When an evil corporation manufactures and sells over 1,400 parts intended to defeat these systems, they’re participating in a calculated subversion of corporate ethics. The “defeat devices” sold by Wehrli allowed heavy-duty engines to spew pollutants at levels far beyond legal limits, effectively socializing the environmental cost while privatizing the profits from the sales.
Allegations and the Timeline of Misconduct
The following timeline details the period of environmental misconduct where Wehrli Custom Fabrication bypassed environmental safeguards for economic benefit.
| Date | Event of Misconduct / Discovery |
| January 2, 2018 | The beginning of the period during which Wehrli manufactured and sold EGR block plates, ECM tunes, and other engine components designed to defeat emissions. |
| February 24, 2020 | EPA performs an inspection of the DeKalb facility, identifying the scale of the aftermarket parts operation. |
| May 15, 2020 | The end of the primary period identified by the EPA where Respondent manufactured and sold at least 1,447 defeat devices. |
| August 4, 2020 | EPA issues a formal Information Request to investigate the sale and installation of parts that render emission controls inoperative. |
| September 27, 2021 | EPA issues a Finding of Violation (FOV) alleging the company knowingly tampered with vehicles and sold defeat devices. |
| February 26, 2024 | The final filing of the CAFO, where Wehrli agrees to pay $267,680.21 and cease all technical support for defeat devices. |
Corporate Pollution: A Tax on Public Health
We must look past the dry legal jargon of “certificates of conformity” and “aftermarket parts” to see the human impact. Corporate pollution is not a victimless crime. The pollutants these defeat devices let loose (specifically nitrogen oxides and particulate matter) are directly linked to respiratory ailments, heart disease, and premature death.
By installing software on at least 101 motor vehicles to bypass emission controls, Wehrli chose to increase the toxic load on the atmosphere. In the world of neoliberal capitalism, the health of a child’s lungs in DeKalb, Illinois, is often weighed against the “performance” of a diesel engine and found to be less valuable than the profit margin of the fabricator.
Neoliberal Capitalism and the Erosion of Corporate Ethics
This case is a microcosm of a larger wealth disparity in the distribution of environmental harm. The people who benefit from “tuned” engines are a small group of enthusiasts and business owners; the people who pay the price are everyone else who shares the air.
This erosion of corporate accountability is a hallmark of an era where regulations are viewed as “obstacles” rather than essential protections for the commons.
The fact that a company could operate for years, selling over a thousand devices intended to break the law, speaks to a culture where corporate greed is often treated as standard business practice until the moment an inspector walks through the door!
Why Corporate Accountability Matters for Society
If polluting corporations are allowed to bypass the law for the sake of “customization,” the fabric of our public health protections begins to unravel.
Society relies on the principle that the pursuit of profit does not grant a license to poison. When we demand corporate accountability, we are not just asking for paperwork; we are fighting for the right to live in a society where the air is not a dumping ground for the sake of a faster truck or a fatter bottom line.
The $267,680.21 penalty is a start, but it cannot retroactively scrub the nitrogen oxides from the air. True justice requires a shift in our values. A shift in values to one where the well-being of the many finally outweighs the illicit “performance” gains of the few.

NOTE:
This website is facing massive amounts of headwind trying to procure the lawsuits relating to corporate misconduct. We are being pimp-slapped by a quadruple whammy:
- The Trump regime's reversal of the laws & regulations meant to protect us is making it so victims are no longer filing lawsuits for shit which was previously illegal.
- Donald Trump's defunding of regulatory agencies led to the frequency of enforcement actions severely decreasing. What's more, the quality of the enforcement actions has also plummeted.
- The GOP's insistence on cutting the healthcare funding for millions of Americans in order to give their billionaire donors additional tax cuts has recently shut the government down. This government shut down has also impacted the aforementioned defunded agencies capabilities to crack down on evil-doers. Donald Trump has since threatened to make these agency shutdowns permanent on account of them being "democrat agencies".
- My access to the LexisNexis legal research platform got revoked. This isn't related to Trump or anything, but it still hurt as I'm being forced to scrounge around public sources to find legal documents now. Sadge.
All four of these factors are severely limiting my ability to access stories of corporate misconduct.
Due to this, I have temporarily decreased the amount of articles published everyday from 5 down to 3, and I will also be publishing articles from previous years as I was fortunate enough to download a butt load of EPA documents back in 2022 and 2023 to make YouTube videos with.... This also means that you'll be seeing many more environmental violation stories going forward :3
Thank you for your attention to this matter,

Also, can we talk about how ICE has a $170 billion annual budget, while the EPA-- which protects the air we breathe and water we drink-- barely clocks $4 billion? Just something to think about....
