I received a notice from GM that my vehicle with the electrical connection to the accelerator pedal which could cause a a reduced power and acceleration condition. However, this is not a recall and I should not seek a repair until I have evidence that my vehicle has this problem. This sounds like a serious safety risk to me. If this condition occurs when I am merging into traffic on an interstate, it could cause a serious accident. Apparently owners are supposed to wait for such an occurrence in order to gather evidence of a need for a repair. I want GM to tell me if my vehicle has this defect in advance and, if so, repair it before the disaster occurs.
