It takes quite the amount of force to stop the vehicle brake pedal started feeling spongy and seems like it doesn’t have enough pressure constantly I have no brake fluid leaks or air in my lines it all comes down to the brake booster it seems like and I know a few vehicles had this problem but mine says it wasn’t but I believe it has been affected.

Soft or spongy brake pedal by model year
What owners say
I am experiencing hard brake pedal and/or brake fade when attempting to apply the brakes. Their is a recall for this problem on other models, however my truck model year is not included for some reason. This has occurred on multiple occasions and has nearly caused an accident on those occasions. My truck also began to roll out of a parking spot and I had extremely hard brake pressure but no response from the brakes.
This happened multiple times. The brake pedal is hard at low idle, and you have to stand on brake pedal to stop the vehicle. Typically happens when trying to back in a parking spot or in stop & go traffic the brake pedal becomes hard to push and truck doesn't stop as quickly
As I was back my boat in at boat ramp brake pedal was hard to press down had to almost stand on them to keep from truck going in the water. I researched this and seen where gm has a recall on the vacuum pump but I call the dealer they told me they wasn't a recall.
Lost brake assist. Coming to a stop the brake pedal whet to the floor and the anti lock brakes started chattering. The brake pedal was hard as a rock and took 2 feet to stop. I was on a 170 mile trip and almost hit someone 2 times.
Original issue: brake pedal hard to push and truck did not stop normally at low speeds. Could reproduce issue usually pulling into a parking spot. My vehicle would have hit car in front of me if I hadn't used ebrake. Took to dealer, dealer applied software update to braking system. Upon pickup I discovered the original issue persisted and now had an additional issue. Now at almost every brake event, the ABS would engage and cause the brake petal to chatter/vibrate. Dealer and gm customer service tried to tell me that was normal after the recall update. I told them that couldn't be normal. It wasn't happening before. After not excepting that as a fix, the dealership started looking for other possibility's. After telling the dealer I was going to take the truck somewhere else they decided to replace the vacuum pump. The new vacuum pump fixed both issues! I'm just saying if the recall update is causing more problems then what it was intended to fix. Now there could be a more serious problem on the highway. Please look into these issues. I feel like gm is trying to hide a big problem.

Vacuum pump, brake pedal stiff when reversing, hard to stop.
Faulty brake vacuum pump leading to reduced braking force under repeated use or in a pannic situation leading to a collision. I hit a deer because I was unable stop or sufficiently slow down to avoid hitting it. I noticed reduced braking force and a hard brake pedal. I have read of several reports on the internet involving this issue
Vacuum pump issue with gmc sierra - I noticed a problem braking my pickup, spongy brakes, hard stopping. I took it to my local chevy dealer (portsmouth chevrolet, portsmouth, nh). They diagnosed it as a problem with the vacuum pump and replaced the pump under warranty. I wanted to alert you because I saw a notice on fox news this evening about your investigation of the problem with earlier models and wanted to alert you that mine is a 2017. You may want to expand the investigation to include later model trucks and suvs. Luckily I caught it in time, no accidents, no injuries.
