- The owner of a SoFlo Custom Hummer EV claims his local dealer just voided his entire warranty.
- He says the dealer initially worked with him on an issue that had nothing to do with the mods.
- Now, he’s sworn off of ever buying another GM product and hoping to somehow get justice.
Dustin Broom says that after suffering a heart attack in April 2024, his outlook on life changed. He decided to trade in his Dodge Hellcat and Audi R8 for the custom GMC Hummer EV you see here—modified by the folks at SoFlo Customs. The truck, he tells Carscoops, “checked all the boxes.” But now, less than a year later, his local dealer has voided his warranty, citing the modifications.
Shortly after purchasing the truck from SoFlo customs, Broom took the SUV to his local dealer for work on the MyMode switch. In addition, his service light has been “always on” he says and as a result, he can’t raise or lower the vehicle. Despite that, features like Crab Walk and 4-Wheel Steering continued to work as expected. Evidently, the dealer has tried to fix these issues since May of 2024.
According to Broom, the GM dealer initially told him the problem was related to a faulty module that needed repair. For whatever reason, something then changed at the dealership. On February 7 of this year, Broom posted in a Hummer EV Facebook group about the development, revealing that GM had refused to honor his warranty.
“Well, guess I get to start litigation with GM. GM service district manager said due to the nature of the upgrades done to my truck (FYI they put bigger tires on it, and painted it, and put different leather interior) my warranty is now completely void. I am never buying a GM product again,” he says.
It’s worth noting that Broom says SoFlo told him the modifications wouldn’t void the factory warranty. However, he says GM didn’t just deny coverage on certain components, it voided the entire vehicle’s warranty.
Was the Warranty Voided Due to Ownership Transfer?
Another wrinkle in the situation is that Broom purchased the truck used, so it’s unclear whether GM intended to cancel the warranty due to the ownership transfer or if something else is at play. In any case, the question remains: Who is to blame here? Should GM honor the warranty if the modifications are purely cosmetic?

Under the Magnuson-Moss Warranty Act, manufacturers cannot void a vehicle’s warranty simply because of aftermarket modifications, unless they can prove those modifications directly caused the issue. Carscoops reached out to both GM, the dealer in question, and to SoFlo customs for more insight on the situation. As of this writing, neither GM nor SoFlo Customs has responded to our request.
The dealership, however, did provide a statement:
“We as a dealership have nothing to do with a warranty being blocked. That comes from higher up in the manufacture. They hold the warranty on the vehicle and that is their decision, we as a dealership have to follow what they tell us to do as they hold the warranty.”
What do you think? Should GM honor the warranty, or is the company within its rights to deny coverage? Let us know your thoughts in the comments below.
