NHTSA Complaint #11681817 — 2017 CHEVROLET TAHOE

There was a recall in 2019 (NHTSA Recall No. 19V645000) on certain GM vehicles for vacuum pump failure, which could affect braking and engine performance. The fix usually involved reprogramming the ECM to improve how the brake assist system operates - not necessarily replacing the vacuum pump unless it had already failed. My local dealership did the reprogramming but in 2025 the vacuum pump totally failed and left my vehicle stranded on the interstate. I had to have towed to a mechanic shop and the inside of the pump had broken into 3 pieces. So I had to have the vacuum pump replaced. During this time my car did not have brakes and put me and surrounding vehicles in a very dangerous situation. The mechanic gave me the broken part to show the dealership. The dealership said there isn’t anything they can do for assistance as I am out of warranty. There was a message that came up that said to service the braking system right before they stopped working.
