The vacuum pump has been recalled on same year, make and model vehicle, yet my particular VIN is falling to the wayside. IT HAS A VACUUM PUMP issue, causing the brakes to malfunction at slower rates of speed. A "computer programming recall" was applied to my VIN however it is the ACTUAL Vacuum pump that is the problem. This should have been covered in all year, make and models. BRAKES ARE IMPORTANT! Reprogramming did not solve the vacuum pump issue that is causing the brakes to fail! This is absolute negligence on behalf of General Motors.

The brakes on my GMC Sierra 1500 lose braking power when operating at slow speeds. The brake pedal will lose braking power, causing the vehicle to not stop at slow speeds. This is particularly troubling when pulling into and out of parking spots, driveways, crosswalks, and other areas. I use my truck to pull a boat and when I back my boat into the water at a boat launch, the brakes will lose power when I am in reverse causing the truck to slid into the water.

I am experiencing an issue with a hard brake pedal on my 2014 GMC Sierra 1500. This same issue was previously addressed through a recall and special coverage program by GM, which I had performed. However, the hard brake pedal condition has returned, significantly impairing stopping power at low speeds. This poses a serious safety risk, especially when towing or parking. I can no longer park my trailer safely. The vehicle is difficult to stop, and braking distance has increased substantially. This is a known issue with this model and year. It appears the prior recall may not have adequately resolved the root cause. I am requesting that NHTSA investigate whether additional action or recall extensions are warranted.

I was backing my boat down the ramp and the brakes were giving out. I know this was a recall issue, in the past, that I had repaired. Clearly, they repaired it with the same faulty part because it has happened again. When I took it to be repaired they said I had to pay for it this time. The issue wasn't resolved but only deferred until later, with a temporary fix. I could have ended up in the river and drowned. Paying the dealership to fix a safety issue caused by their defective parts is ridiculous.

When I am braking at low speed my brakes start locking up and eventually do not work. This has happened on multiple occasions. I have almost wrecked multiple times I rarely drive my truck now cause it is unsafe. There is a recall on the brake booster 2014 to 2018 gmc seria but my truck vin is not included on that recall and it’s doing the exact same thing. GM recalls 3.4 million pickups and SUVs over brake pump Sept. 12, 2019 1 The recall includes the Chevy Silverado and GMC Sierra (model years 2014-2018), and affects a vacuum pump defect that may make it more difficult to brake at low speeds.

Noticed that there was a recall on this vehicle NHTSA Campaign Number: 19V645000. My concern is that I took my vehicle in back in 2018/2019 for this repair. However my vehicle vacuum pump completely failed the other day where I cannot brake. My vehicle is only at 70,800 and fail to see that if a proper repair was completed back in 2018/2019 for it to fail again a couple of years later with low mileage. While I was able to get this vehicle home safely my concern is that if it failed earlier in the day on the highway I may have cause a serious incident.

Going under 15mph, applying the brake causes the pedal to become stiff and lock up and not work. This has caused me to almost hit someone in traffic. I immediately got off the road and got my vehicle to a safe location off the road . Communicating with a dealer today to confirm possible recall issue or potential repairs.

Whenever driving I get a message stating that I need to service my trailer brake system. This is most likely due to cheap wiring installed by the manufacture. This has been going on for over a couple of months. Just recently, I was making a slow turn and my vehicle shut off on me and I lost control of my brakes and steering and all power to the vehicle which is a huge safety concern and I am unsure if they are related or not
