NHTSA Complaint #11549947 — 2015 CHEVROLET SILVERADO 1500

The power assist for the brakes intermittently goes out and does not work, typically happens at low speed like when parking. The most recent time this started happening a ‘brake assist’ notification appeared on my dashboard. This is a safety concern. I see a recall for my model and year, but when I inquired was told my VIN was not covered. The existing recall number that I believe should be expanded to cover my VIN is recall number N192268490 and is also listed as NHSTA campaign numbers 19V645 and 20V603. Please look into this and expand the recall to cover my vehicle and others that should be covered for this safety defect.
