“It has happened several times when going slow the breaks get really hard to stop the vehicle. Otherwise breaks are new work well. One time I hit my garage as I tried to move it slightly forward. Another time I was slowly moving forward & tried to stop at a driveway as person was walking by. I pressed breaks down as far as the could go.”

“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.”

“The contact owns a 2017 Chevrolet Tahoe. The contact stated that occasionally while driving at various speeds, the vehicle failed to accelerate as intended while the accelerator pedal was depressed, and the RPM was elevated. In addition, the contact stated that the vehicle would brake independently while the accelerator pedal was depressed. The check engine and Electronic Stability Control warning lights would occasionally illuminate. The contact stated that restarting the vehicle was a temporary repair; however, the failure persisted. The contact stated that the windshield wipers activated independently, and all four doors locked independently. The vehicle was taken to a local dealer where it was diagnosed with a fuel injector #6 failure; however, the part was replaced approximately one month prior to the failure reoccurring. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control (ESC); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 95,000.”
