Engine Knocking Noise problems of the 2016 Toyota Tacoma

Knocking noise from vacuum pump after engine is warm. Base on the NHTSA id 10133645 - Toyota technical service bulleting t-sb-0316-17. Because of the safety hazard involve in the probably defective part, and because of my medical condition at the time of the Toyota service bulleting I could not take the vehicle for the technical service bulleting to DE Toyota dealer until 11/18/2019 ( after the applicable warranty of 36 months or 36,000 miles - customer number 192461 at adriel auto in rio grande puerto rico. There the vehicle was inspected by a technician # 443901. At the moment of the inspection the technician did not found the condition that I was concern about. I was told that that knocking sound from the vacuum pump was normal. That I should not to be worry about it. Because of my medical condition and treatment. I was not able to follow up my complaint at Toyota DE puerto rico. Now that I am feeling a little bit better I am reporting this to you with the hope that a solution be found. I have never own a vehicle from any manufacturer that had such a knocking sound from the vacuum pump. I am concern about my safety and the safety of others if my brake system fails and someone gets injure or kill. It is my perception that the knocking noise from the vacuum pump is a safety hazard and that Toyota corporation must replace the defective part. My vehicle have only 10,000 miles because of my illness and also because I do not feel safe driving it. I know I am a bit late to report this condition on my vehicle and that the warranty period have expire. But the problem persist, as a remedy I am requesting that all of the Toyota vehicles that present this knocking noise from vacuum pump should be recall an repair under an extended warranty. Thank you.
