Summary of Investigation: Welcome to the webpage maintained by Shepherd, Finkelman, Miller & Shah, LLP ("SFMS") for its investigation into potential warranty violations by General Motors in connection with GM vehicles, including vehicles manufactured under the GMC, Cadillac, and Chevrolet brand names. Specifically, SFMS is investigating alleged defects related to the electrical system wiring, wiring harnesses, and related components. Allegedly, these systems and components contain soy-based materials that attract rodents and animals, who chew through them and leave owners of the vehicles with disabled or improperly functioning vehicles. We believe that GM does not cover the defect under warranty, so that the consumer must pay for the replacement wiring. If you have experienced these or similar problems with your vehicle as a result of an electrical and/or wiring system issue, please contact us by calling (866) 540-5505 or filling out this form.
