Consumer Description

I received an official safety recall notice from GM (Recall Number N252494000) for my 2021 GMC Yukon due to a defect in the engine's connecting rod or crankshaft components. GM stated that this defect can cause engine failure and loss of propulsion, which significantly increases the risk of a crash. The notice also confirmed that parts to fix the issue are currently unavailable and provided no timeline for resolution. Despite the serious safety risk, GM and my local dealer have not offered a loaner vehicle while waiting for the repair, leaving me without a safe means of transportation. I am filing this complaint because I believe GM is not taking sufficient steps to protect customers from a known and documented safety hazard.
