From the day of purchase the brakes never seemed to be adequate. You would have to push harder on the brakes than normal to make the truck stop. During routine service the dealership reported the brakes, drivers side rear were almost metal to metal and the rear passenger side was slightly better. The front brakes were 2/3 worn and all of the pads needed to be replaced. This truck is leased and has only 32000 miles on it therefore shouldn't need to be replacing brakes at such a low mileage. Per the dealership it is our responsibility to pay for the repairs as brakes fall under the normal wear and tear of a vehicle. Again, we feel that with only 32000 miles brakes shouldn't have to be replaced and should be the responsibility of GM to rectify this problem. This is the 4th new GM truck that I've owned or leased and have never had any issues before with brakes.

Power brake failure. Lost brakes pulling into parking space. Parking space barrier stopped the truck. Brakes began to work again after letting truck sit and restart engine. Very dangerous! took vehicle to dealer and they found the vacuum pump failed internally. Dealer would not cover repairs for faulty vacuum pump despite safety issue. Total cost was $724+tax. Only 43,000 miles on truck. GM knows about the problem and will not address. Service bulletin pit5361B.

My brakes do not properly function in wet weather conditions. The brake petal becomes extremely stiff, as if there is air in the brake lines. This also results in a significant loss of stopping power. While jamming the brake pedal as hard as I can, the pads never make significant contact with the rotor. I have already damaged my bumper because of this. I was attempting to park during heavy rains. While pressing my break petal, I noticed the immediate loss of stopping power. I could not stop in time, colliding with the parking barrier pole. The loss of stopping power happens routinely during rain.

On three occasions my 2016 Chevy Silverado ltz Z71 brakes failed to work. The first time I rolled half way into a intersection before I came to a stop. The second time was at an singnal controlled intersection. After both of these incidents the brakes started working perfect and I was not sure if there was a problem or not. The other day this happened agsin but this time I was in a parking lot. I was able to test the brakes and as I went back and forth I had trouble coming to a stop as I pressed the brake pedal as hard as I could. I brought the truck to Chevy service and was told the brake vacuum pump or something like that was failing. They stated I was just out of warranty and I'm responsible for the cost. I don't feel like I should I do be responsible for a part that they said is not supposed to fail. This is also concerning if there are other Chevy truck out on the road that randomly will not be able to stop.

The first set of brake pads were GM replacement, they did not stop the truck as well as the original. So I replaced the pads with raybestos brake pads, still not satisfied with the stopping distance. Again I went with Napa ceramic pads they caused the breaks to squeal when the brakes were applied. Now my mechanic has replaced them with O relly name pads and the stopping distance is still increasing. The other problem was around 58,000 miles my truck began shifting hard and jerking. When I took it to deacon jones Chevrolet in smithfield nc, they replaced the torque converter at no charge. Now at 63,000 miles its doing the same thing. GM states even if they replaced the part the warranty only covers to 60,000. Miles. When asked about the part warranty same response 60,000 miles. Checking with several mechanics in the area and on line both incidences seems to be a reoccurring problem for people who own trucks of this period. Please check into this.

Dec 1st 2018, I'm in a parking lot pulling into a parking space head first, when I needed to straighten my truck out, I put it in reverse to pullout and straighten it out, when I hit my brake pedal suddenly the pedal has a lot of pressure and makes it difficult to come to a stop. Then pull forward again to park and yet the pedal becomes rock hard making even more difficult to stop the truck moving forward, a couple feet. Then finally stopping before hitting the car in front of me. I now call the dealership to take it in and see what's going on because now this puts myself, my family, and everyone around me in danger if I'm not able to stop my truck.

The brakes became very difficult to press while trying to stop from a slow speed. This happened several times while either in stop and go traffic or going through a drive through. I had to press extremely hard on the pedal in order to prevent from hitting the vehicle in front of me. This issue did not seem to occur at higher speeds.

I believe Chevrolet 1500 series trucks are not manufactured with brakes that stop the vehicle soon enough. I have a problem when I have driven my truck for a while, long enough that the brake system gets pretty warm, or down hills, ,( not steep hills). The brakes do not not brake very well, along with making a grinding - rumbling noise from the front of the vehicle. It also feels like like the brakes are metal on metal. I have asked the dealership to check into it, and the say, nothing wrong, brakes have lots of brake pad left. When I ask them if they have heard of any issues regarding brake fade, and noise, they say no. Last year GM came up with a front brake upgrade kit in their parts department, which is a 6 piston calliper and upgraded pads for the truck, but it costs $4000. On the 2019, they have added this upgrade kit as an option when you build and price a new truck. That tells me that that they know there is an issue with their trucks, but they won't admit it.

If you continue to apply brakes the pedal becomes rock hard. Vehicle will continue move forward or backward no matter what pressure you apply to pedal. The vehicle will move several feet before coming to a stop. This occurred to me while at a city crosswalk. Huge safety concern with vehicle not stopping.

The 8th of November 2018 while traveling through austin, tx - in heavy traffic; I nearly rear-ended another vehicle - the brakes got real hard, but the vehicle kept rolling. The brakes acted like the engine was shut off. I tried them again after resumed speed- and I tested them - on the third pump - they were rock-hard again. A vehicle shop in san antonio was able to consistently replicate the problem. It was a bad vacuum-pump-assist. It cost me $455, it could have been worse, the mechanic told me that oil from the engine could have damaged the vacuum booster and/or the master cylinder. He told me Chevy knows about it - #pit5361B - but I never knew about it - I almost rear-ended another vehicle. Vehicle had 48,500 miles when it occurred.

Vacuum pump failed resulting in property damage

- Oak Grove, MN, USA

I own a 2016 Silverado with a faulty brake vacuum pump. The issue was rectified by a GM dealer, and service records are attached. I am filing a compliant to ensure NHTSA is aware of a dangerous defect in this truck. The issue became apparent over the course of weeks. Initial problems included an audible clicking noise once the brake was depressed. As the problem progressed the vehicle would not be able to brake when trying to brake on inclines as flat as 2 degrees. In fact, brakes would fail and ABS would kick in when backing out of my driveway. Youtube video summarizes issue https://M.youtube.com/watch?V=0krkyevbcu0

Its been going on for awhile too. And my powertrain when I in the street or highway going 60mph it tends to shoot the rpms N go down and like the transmission want to shift down on its own.

On 3 separate occasions, my brakes failed me causing me to almost crash. The first time, I was stopping at a stop sign from going less than 5mph (I was inching up after about 10 cars were in front of me). I had my foot on the brake the whole time and never accelerates and all of a sudden, the truck wouldn't stop. I was on about a very slight downhill (maybe 1 degree). It felt like the brakes became slippery and just sounded awful. I came within a few inches of the car in front of me and almost rear ended them. The next occasion, I was going downhill and to the left and has to stop. The truck did the same thing where the power brakes seemed to fail or the brakes just didn't want to work. This time I was going about 35mph and had to swerve into the wrong lane to avoid crashing. Thankfully nobody was coming otherwise I would have had to rear end the person in front of me. I was probably 5 or 6 car lengths behind him when we both hit the brakes at the same time. The 3rd time this happened was this morning in the same spot as the second incident. This time, I was testing the brakes. I'm very scared that something is going to happen because of this and would like to get this fixed asap. I bought this GM certified vehicle about 1 month ago and should be in good mechanical condition. These 3 incidents happened in a 10-14 day span and 2 times in the past 3 days.

While attempting to brake at low speeds the brake booster and pedal failed causing me to use excessive brake pressure to get the the vehicle to stop. Due to this I was almost involved in a crash the vehicle only has 50K miles.

I stopped to eat at a restaurant and my brakes got extremely hard and my truck did not stop I used both feet to jam the brake down as hard as I could to stop. There was a car in front of me but it was pulling out as I pulled in. My truck would have struck this vehicle if it weren't for them pulling out. I went directly to a nearby mechanic to see what is going on with my truck. They told me the vacuum pump is faulty and that GM has a bulletin about this issue. So GM is aware of the issue and knows their vehicles are dangerous to its customers and the public. But they have not ordered a recall to fix the faulty vacuum pump.

Brake pedal gets really hard and has become a safety issue with everyday driving. Turn off engine and resets and works again.

- Laredo, TX, USA

When backing up lost power brake assist, also when pulling forward, was dropping my boat off in storage causing my to use the brakes a lot when backing up, no power assist when pulling out of garage when leaving, when going down road brakes came back to operate as normal. Now after backing and braking 3 times power assist is gone but returns when driving normal. Have appointment at dealer tomorrow for cal problems (dashboard says cal and smartphone remote start does not work) will have brakes checked.

- Bingham, ME, USA

The brakes have failed to stop the vehicle in 2 separate occasions in speeds less than 5 mph. The has been reviewed by a certified Chevrolet mechanics and they since they cannot replicate the issue, they don't feel it is a major concern. I want to ensure that others are aware as I have stopped driving the vehicle due to the safety concern. I am currently working with Chevrolet to turn the vehicle back into them since I do not feel safe driving it.
