Chevy is aware of this issue. The brake vacuum pump needs to be moved onto a broader recall and not just under a "special coverage" this past weekend at gas pump our break pedal and the ability of the car to stop almost caused a major tragic accident. Fortunately last minute the truck stopped after I put both feet on the pedal and pushed as hard as I could. This issue left unresolved will get someone killed. These vacuum pumps need to replaced and Chevy needs to stand behind the issue.the people that don't have 600 bucks to replace these pumps are driving around with a loaded weapon on the streets if they are outside the parameters of their bulletin. I know Chevy will do the right thing and recall and fix this brake problem. This was at slow speeds in a gas station backing to get closer to the gas pump. There was no accident, no report filed, or police called but this could have ended poorly.
The brakes seem to loose power. It appears that the vehicle is loosing vacuum and the operator looses power brakes. I almost rear ended a car during a traffic backup on the interstate because of the loose of power braking efficiency. The vacuum pump is not making the appropriate amount of vacuum to have power brakes.
The contact owns a 2015 Chevrolet Suburban. While the contact's wife was driving 50 mph, she heard an abnormal sound. There was no warning indicator illuminated. The vehicle was not able to be driven. Upon inspecting the vehicle, the contact stated that the front brake caliper was missing a bolt. The contact called hertrich Chevrolet Buick GMC (located at 7677 ocean gateway, easton, md 21601, (410) 200-9757) and notified them of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified. The failure mileage was 74,247.
Brakes do not work correctly at any low speeds. Was diagnosed by a certified mechanic as a brake booster pump. The car is completely unsafe and undriveable until I get it repaired.

When backing up or driving forward slowly the brake peddle gets really hard and vehicle is very difficult to stop. Almost was not able to stop. I was in a parking lot, used my emergency brake to stop as well as putting the car into neutral.
Was coming up to a stoplight with major traffic and had stiff to no brakes. Was within inches of hitting the person in front of me. My 'service brake assist' light came on. I was told by a Chevy service department that my brake vacuum pump had failed and that this was common in the 2015 Suburban.
I was driving my 2015 Chevrolet Suburban with 7 family members at about 45 mph as we were coming into a city. Two of us started to hear a slight squeal like when a belt slips. After that I shut off the A/C to see if it was that. It was not. About that time traffic started to slow down in front of me. When I stepped on the brake to slow down it was hard and at the bottom of the pedal stroke. I lifted the pedal with my foot and it just fell back down. I was able to get the Suburban to stopped in time before hitting the car in front of me. I had to drive the vehicle cautiously for another mile or so to find a safe spot to pull off. I had the vehicle towed 90 miles to a dealer close to a relative as we live another 250 miles away. When I talked to the dealer, he said there was a service bulletin for this issue but I believe he aid it was only covered up to 69,000 miles. Our Suburban has 108,000 miles on it as we live in a very rural location. It is 45 miles on way to the grocery store. I have owned GM products all my life and have never been as disappointed in their handling of their customers as I am now. This issue with the brake vacuum pump has been a known issue and they are not covering the repair of it.
Vehicle was in motion, at slow speeds (under 25mph) and when the brake is pushed, the brake pedal became hard but failed to stop the vehicles forward motion. This happens intermittently and is a huge safety issue. This occurs only at slow speeds and prevent the driver from stopping the vehicle even if the brake pedal is pumped. This occurred again today and Chevy was contacted and stated they have no recalls or issues with their brake system even though there have been numerous complaints logged to NHTSA. When this occurs there is no braking for the vehicle and will cause an accident if not fixed.
Break assistance stopped working as I pulled into a parking spot at work. I needed to put extreme pressure on the break pedal in order to stop the truck at very low speed. Vacuum pump was replaced in truck
On at least 5 occasions the brakes have failed to provide the necessary stopping power. When inching forward after a complete stop, I would apply pressure to the brake pedal and the pedal would immediately lose pressure and sink to the floor. I would have to apply additional pressure to the pedal in order to stop from hitting the vehicle in front of me. It would also feel like the ABS system would kick in and would pulsate. If I immediately depress the brake pedal and press it again in quick succession the pedal regains pressure but does not regain normal brake functionality.
On quite a few occasions over the years, while driving at low speeds and depressing the brake pedal, the car has been very difficult to stop. This presents a scary situation because I am a 200 lb man and I can barely stop this large vehicle. My fiance is very petite and she is terrified to drive it. I know this is a very common problem with the 2015 Chevy trucks and SUV's because I personally know others with this exact same problem. It seems as though Chevy is just biding time awaiting for the auto warranties to expire rather than fix this deadly problem.
Driving at slow speeds pulling a trailer, vehicles brake pedal was very hard and they would not stop vehicle. Another time without trailer same thing, very very hard brake pedal at slow speed, could not stop vehicle had to apply emergency brake with putting the car in neutral and then in park to stop.
The contact owns a 2015 Chevrolet Suburban. While approaching a stop light and depressing the brake pedal, it failed to stop the vehicle. The contact had to apply excessive force to stop the vehicle. As a result, the contact rear ended a cement vehicle. There was no warning indicator illuminated. There were no injuries. A police report was not filed. The vehicle was able to be driven and was taken to an independent mechanic where it was diagnosed that the vacuum pump needed to be replaced. The contact stated that the vehicle previously experienced brake failure. The contact called classic Chevrolet Buick GMC of cleburne (located at 822-walter P. holiday drive, cleburne, tx 76033, (817) 402-3167) and was informed that they would cover the vehicle at 70 miles. The vehicle was not taken to a dealer and was not repaired. The manufacturer was notified of the failure and informed the contact to take the vehicle to a dealer. No further assistance was offered. The approximate failure mileage was 106,000.
While traveling straight on the highway last March in warm, dry conditions, the brakes become extremely difficult to push down, resulting in dramatically reduced stopping ability. I could not push the brake pedal down no matter how hard I tried. We had to move over to the shoulder of the road and slow gradually to avoid hitting vehicles in front of us. $1,000 repair required for vacuum system. Not covered by warranty. Dealer denied this was a common problem.
Brakes must be pushed extremely hard to stop the vehicle. Vacuum pump for brake system is faulty. GM will not cover or warranty as the bumper to bumper warranty has expired. Braking issue has nearly resulted in collisions. Called murdock Chevrolet on April 24, 2019, but they stated they were not aware of any recalls or service bulletins related to the pump or brakes.
At low speed (backing into a parking spot on the street) the brake pedal got very hard and the vehicle would barely stop. I then did not go into that space to avoid hitting the car behind me. I pulled into a parking lot across the street. When backing in, I could not stop (moving with car at idle engine speed). The hitch hit the concrete wall-happily no damage done. With research, I find this is a common problem that GM has not addressed. I usually occurs at slow speeds or stop and go slow speed traffic. This is unpredictable and very unsafe. The vehicle is a 2015 with only 35,000 miles. The vacuum pump (the failure) is bolted to the engine and engine-driven and lubricated by engine oil which puts my engine at risk. Yet none of this is covered by the power train warranty. This is not a slow, but a sudden failure item. Very unsafe if it happens in school parking lot picking up my children, church, close spaces (neighborhoods, parking areas).
