2022 Hummer EV 10 Recall

General Motors last week issued a recall for the 2022 GMC Hummer EV. The problem affected only 10 vehicles that rolled off the GM line in Detroit, with production dates between October 2021 and January 2022..

What is the fault that affects these models?

The problem stems from the taillights, specifically the fact that they weren鈥檛 exactly working. According to the defect report filed with the NHTSA, the software that controls the taillights could cause one or both lights to stop working or come on at the wrong time. And when this failure happens, it would also disable the brake light, turn light, reverse light and side marker.

In other cases, the lights would stay on even after the vehicle was turned off. In case you were wondering, this is a violation of Federal Motor Vehicle Safety Standard 108, 鈥淟amps, Reflective Devices, and Associated Equipment.鈥

GM quickly and effectively fixed the problem

GM discovered the problem after an employee received two field reports of taillights not working properly. After opening his own investigation, GM discovered the problem and began taking the necessary steps to initiate a recall. Replacing the taillights with parts that have the correct software is all it takes to fix the problem..

In fact, it was such a simple fix that all 10 affected vehicles have already been repaired. A GMC representative said the automaker has contacted all affected owners directly and has already replaced the taillights. Other Hummer electric vehicles were also affected, but since they were still in GM鈥檚 possession, they were also repaired.
