GM Faces Class Action Lawsuit in the U.S. Over Faulty Home Chargers

A class action lawsuit has been filed in the United States against General Motors over alleged defects in its Ultium PowerUp home charging units. The complaint, submitted to a federal court in Florida on October 28, 2025, comes from customers who purchased the chargers in August 2024.

According to the plaintiffs, the devices frequently malfunction — an internal fuse trips, interrupting the charging process. In some cases, they claim, the units overheat to the point that the car’s alarm system is triggered.

The lawsuit covers customers who bought PowerUp chargers between 2022 and 2024 through authorized GM dealerships. The filing alleges that the company was aware of potential issues but continued selling the product. The complaint concerns the original PowerUp model, not the updated PowerUp 2 version, which features a more compact design and improved internal layout.

The case adds to GM’s growing list of legal challenges as the automaker navigates the complex rollout of new technologies and the rapidly expanding electric vehicle market.
