GM Voids Warranty on Customized SoFlo GMC Hummer EV | Carscoops

      An owner claims that GMC collaborated with him initially regarding an issue, but then abruptly nullified the warranty on his Hummer EV.

      The proprietor of a SoFlo Custom Hummer EV asserts that his local dealer has voided his entire warranty. He maintains that the dealer was initially cooperative about a problem not related to the modifications. Now, he vows never to purchase another GM vehicle, seeking some form of resolution.

      Dustin Broom states that following a heart attack in April 2024, his perspective on life transformed. He made the decision to trade his Dodge Hellcat and Audi R8 for the custom GMC Hummer EV, modified by SoFlo Customs, which he claims “checked all the boxes.” However, less than a year later, his local dealer has voided the warranty, attributing it to the modifications made.

      After acquiring the truck from SoFlo Customs, Broom took the SUV to his local dealer for issues with the MyMode switch. He also mentioned that his service light has been “always on,” preventing him from raising or lowering the vehicle, although features like Crab Walk and 4-Wheel Steering functioned normally. The dealer has reportedly attempted to address these issues since May 2024.

      According to Broom, the GM dealer initially informed him that a malfunctioning module was the source of the problem. However, things seemingly changed at the dealership. On February 7 of this year, Broom posted in a Hummer EV Facebook group, disclosing that GM had declined to honor his warranty.

      “Looks like I’ll have to start a legal battle with GM. The GM service district manager stated that due to the nature of the modifications made to my truck (for instance, larger tires, paint, and a different leather interior), my warranty is now completely void. I will never buy another GM product,” he commented.

      It's important to mention that Broom claims SoFlo assured him that the modifications wouldn’t void the factory warranty. Nonetheless, he asserts that GM didn’t just deny coverage for certain parts, but rather voided the entire vehicle’s warranty.

      Was the Warranty Voided Due to the Transfer of Ownership?

      Another factor complicating the situation is that Broom bought the truck used, raising questions about whether GM aimed to cancel the warranty due to the transfer of ownership or if other factors are involved. Ultimately, the question persists: Who is at fault? Should GM uphold the warranty if the modifications are solely cosmetic?

      According to the Magnuson-Moss Warranty Act, manufacturers are not allowed to void a vehicle’s warranty simply because of aftermarket modifications unless they can demonstrate that those modifications directly caused the problem. Carscoops reached out to GM, the dealer in question, and SoFlo Customs for more information, but none have responded as of this writing.

      The dealership did, however, provide a statement:

      “As a dealership, we have no control over warranty denials. That decision comes from higher up in the manufacturer. They are responsible for the warranty on the vehicle, and we must adhere to their directives.”
