Accelerator Pedal Sensor Problems of Buick Regal

Vehicle had recall 12212"a" performed in oct of 2014 at delarship, this results in sometimes if not every time of a mis-calibrated brake position sensor. The mis-calibration results in my vehicle requiring the brake pedal to be depressed almost to the floor before the park position disengagement sensor is activated. It is at this point when the brake lights are activated. This extra pedal travel results in me being able to come to a rapid stop from 85 miles an hour on the freeway without any rear brake lights activating. The brake lights are not intermittent, they activate every time the pedal is pressed far enough, while driving this is only at the point when abs would be activated under emergency braking. Buick/GMC is aware this is the case and issued recall 12212"b" on oct 11, 2016 which reads: "this bulliten has been revised to include a note before step 4 of the service procedure. Please discard all copies of bulliten 12212a. " the note states: "the brake pedal position sensor calibration must be performed after the brake pedal position sensor,bcm,ecm, or hpcm have been serviced. " Buick/GMC has not informed drivers under the original 12212a recall that their brake lights will not activate because of this recall service and have refused to honor this newly updated procedure on my vehicle and shows as "complete" on nthtsa website. Bottom line the original botched 12212a results in brake lights not activating and anyone that had 12212a done should get 12212b notification and recall coverage.
