NHTSA Complaint #11670508 — 2017 CHEVROLET SILVERADO 1500

I experienced issues with braking including shuddering brakes. I took the vehicle to a repair shop who looked into any active recalls and there were none, I had the electronic brake control module recall completed in 2019. The shop replaced the front brakes and resurfaced the back which did not fix the issue. They then replaced the vacuum pump which did fix the issue I was responsible for all costs. I recently noticed my vehicle is covered under special coverage N182202780 through 2027 which covers the cost of the vacuum pump replacement. Chevy is refusing to reimburse for the costs because the work was not done at their dealership despite not having a recall that States that. I would like the issue addressed theough a formal recall and reimbursement of repair costs as Chevy is obviously aware there is a safety issue related to braking due to failing components.
