Consumer Description

My engine is currently experiencing loud knocking/shaking. It worsens as my vehicle is accelerating it is causing my engine to lose ability to accelerate which has posed a safety concern. This vehicle is my main source of transportation for my family. We have taken this vehicle to the dealership where they were unable to service due to the recall not being open and available and i have contacted GM customer service with no remedy to be issued at this time. The dealership cannot perform any maintenance pertained to the recall and yet cannot remedy. I am concerned for my family's safety. I was advised that i shall continue to drive the vehicle until it breaks down or the recall is open for repairs.
