2015 CHEVROLET SILVERADO 1500 Service Brakes Problems

Driving the truck, a nut fell against my foot. I pulled over and looked underneath to where this Nut could have come from. I realized that the brake pedal was very loose. I did a Google search to see what break pedal Nut could have loosened and Fallen off. I identified that there was a recall for the brake pedal pivot nut on these trucks. From that, I looked up to that section and found that the nut did indeed come from that part. I called the local Chevrolet dealership and they informed me that my VIN number was not part of that recall list. It is obvious that General Motors left the numbers off of that recall for vehicles that are still being affected by that problem. I called General Motors customer service and spoke to Brandy at customer service and she was not willing to help and only...

Brake pedal bolt came loose and fell off. Brake pedal was difficult to use. There was a recall for this issue on 2015-2016 2500 and 3500 series trucks but not 1500 series. I have a video of the brake pedal condition but it will not let me upload it.

I am the original owner of a 2015 chevrolet silverado 1500. The vehicle's brake vacuum pump has failed, resulting in a sudden, significant loss of power braking assist. This requires excessive pedal force to stop the vehicle, creating an immediate safety hazard and increasing the risk of a crash. General Motors previously issued special coverage adjustment N192210240 ( or N182202780 ) to address this specific component failure, extending warranty coverage to 10 years or 150,000 miles. I never received notification of this coverage or the potential safety defect. The dealership has confirmed the vacuum pump failure but denied coverage because the 10- year window has recently expired. I contacted GM Corporate on 12/16/2025 and 12/17/ 2025 they declined GoodWill Assistance. I believe it is unreasonable to deny coverage for a know safety defect on a vehicle owned by the original purchaser who was never properly notified of the extension on...

I pulled into a parking lot, and into a parking spot. I put the truck in reverse to back up and straighten the truck, when I started to pull back in the brake pedal became hard to press. I had to stand up on the brake pedal to keep from hitting the car parked in front of me. It also happened another time while backing out of a parking spot when someone walked behind the vehicle, and I had to stand on the pedal.

Vacuum pump for brakes . My brake pedal get hard

Vacuum pump failed causing an anti-lock brake failure and destroyed all my brake pads and rotors. General motors and the dealership are only covering the vacuum pump, but require me the customer to pay for the brake pads, rotors, and installation fees. GM had the dealership perform 3 days of testing to verify that it was the vacuum pump. I was hauling a camper with my truck when it failed with my 2 young children inside and the truck ground to a halt while shaking violently scaring my children. I had to have the vehicle towed due to how dangerous the issue was.

Unknown : vehicle vacuum pump for Braking assistance causing the vehicle to not be able to stop possibly crashing.

GMC knows there is a problem with the Vacuum Pump Assembly/Belt Kit and are refusing to recall it. The breaks are harder to press (see attachments) and the alarms are constantly dinging. My truck has less than one hundred and fifty miles and I bought it 12/07/2015, they have a special warrant on these vehicles but will not honor it. This is dangerous not to have the proper breaking power.

-Vacuum pump malfunction. Not available, has already been repaired. Found out after the fact there had been a recall on 2014-2018 vacuum pumps. Mine had not been included in the recall, yet here we are. -While pulling into a parking spot, as I was slowing down/braking the pedal went to the floor, truck accelerated went over a parking barrier, sidewalk and hit a tree. If I had not hit the tree, I would have driven into the side of the building into people doing cardio or if someone had been walking in front of me, I would have hit them. Seeing an orthopedist on June 10 for right hip and knee pain as leg was fully extended on impact. -Quality GMC Collision/Service tested/drove the car and it didn't happen. Service ran diagnostics and it happened then. Highlighted in yellow on repair invoice. -Quality GMC Collision/Service. don't know if an adjuster...

Pulling forward in my driveway and my breaks went stiff

I received the recall notice and then the special warranty notice, fall of 2019. I took my vehicle, which was experiencing the braking issues described in both notices, to Nereson Automotive in Detroit Lakes, MN. I did call ahead & had an appointment and informed them of the letters and the problems both on the phone and in person when dropping the vehicle off for repairs. After they called me and told me they made all the repairs and had the vehicle in good working order again, I picked up my 2015 Chevy Silverado High Country (approximately 107,000 miles) and while still on the lot I experienced the same braking issues. At that point I just figured it was something that I would have to deal with. After almost 5 years of dealing with the intermittent annoyance, I started doing some research on how to fix it myself and came...

Low speed brake failure sometimes

Vehicle shuts off when stopping. Everything goes dead. It will eventually start again, but very annoying. What happens when it shuts off going down the highway? No power steering or power brakes, that's what!

The trailer braking system keeps chiming and going on and off ever 1-2 sec. Detracting and over rides all other information on screen. Including speed. Has been happening for months and now consistently.

the brake booster stop working or shortated out and broke the belt now the brakes are hard to push while i was driving

At 10mph to 30mph every other week I will get a sudden brake lock up and release for a split second. There are no codes that get thrown, it is very dangerous... being a disabled veteran, I did check is it says all my recalls have been done but I don't think they were done right.

While in a drive thru moving up slowly to the next spot brakes became hard and had to put a lot of force on the brakes to make vehicle slow down and stop. I thought I was going to hit the car in front of me but luckily stopped within a few inches. Took it in to get serviced and mechanic said brake system checked out to be good. That was 2 years ago. This last week I was backing in a boat in the water and the brakes became hard to push and was not slowing the vehicle down. I had to put on the emergency parking brake in order not to go in the lake with the truck. It was a very scary situation with my small nephews in the back seat. I was able to drive the truck back 10 homes from Canada. This appears to be...

Truck has issues breaking at very low speeds such as drive thrus ect. Zero issues at driving speeds. I see there is a recall for this issue on silverados between 2014 and I believe 2018 that had to do with a vacuum pump or similar issue that caused breaking issues at low speeds. For some reason my truck is not included in this recall but is having the same issues.

Mi camión está marcando un problema de servicio del sistema de freno de remolque y amanece con la batería baja y cuando voy conduciendo la mayoría de tiempo se pone muy duro el pedal del freno y hace un ruido muy raro cuando freno y también cuando acelero truena cómo si trajera un Fierro suelto en el motor

BRAKING SYSTEM HAS BEEN A PROBLEM FOR A LONG TIME. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP. THERE THE MECHANICS REPLACED THE FRONT BRAKE PADS AND REAR BRAKE PADS. WE CONTINUED TO HAVE PROBLEMS WITH THE VEHICLE. WE WERE NOT AWARE OF THE RECOMMENDATIONS TILL RECENTLY SO WE TOOK THE VEHICLE IN TO DEALER. MILEAGE WAS 169201. THE BRAKES WERE FIRST INSPECTED 6-29-22. THE MILEAGE AT THAT TIME WAS WELL BELOW YOUR CUTOFF OF 150,000 MILES OR 10 YEARS. THE DEALERS HANDLING OF THIS DOES SEEM UNREASONABLE. THIS IS MY HUSBANDS VEHICLE I REALLY DONT KNOW EXACTLY WHAT HAPPENED AND WHAT DATES. WHILE BACKING UP HIS TRAILER HAS BEEN A PROBLEM SEVERAL DENTS ON THE SIDE OF IT SHOWS BRAKING PROBLEMS. I THINK 1900.00 IS EXTREME TO REPAIR WHAT YOUR COMPANY IS WELL AWARE OF IS A PROBLEM. YOUR CUSTOMERS SHOULD HAVE BEEN NOTIFIED THIS WAS POSSIBLE RATHER...

At slow speeds, such as parking lots and moving in slow traffic, the brakes seem to fail or act like they are giving out.

The TRAILER STABIZER warning keeps coming on.

My 2015 Silverado was purchased new and around October 2023 the trailer brake service warning started popping up. I was concerned with pulling any sort of trailer that my safety would be at risk, and also the constant noise as a distraction. I have taken to dealer for inspection, but nothing was able to be done at the time. No other warnings or symptoms have appeared. Just the trailer brake service continually going off. Thanks.

Brakes are hard at low speeds

Brakes fail at low speeds,or cruising in to a parking lot

While backing up on an incline the brakes stop working and pedal vibrates like abs is kicking in. Have to use e brake to stop

As I was driving, the brakes got all Smashy the pedal locked and the brakes started grinding. I couldn’t stop the truck anymore. I couldn’t do absolutely anything I had to stop and hit a divider from a parking structure to be able to stop my truck. My truck is a 2015 Chevy Silverado, I do maintenance all the time I almost took out four cars and injured. These people along with myself. This is uncalled for something is wrong with my brakes. I took a video right after and you see on the video how the brake is just stuck it won’t even go in or anything you hear , a marshmallow sound you feel the grinding it’s horrible .

#1- I had my truck in a few years ago for a brake issues that they said was a computer reprogramming issue and vacuum pump. They repaired and the issue slowly came back. Now it feels as if there is little to no assist with braking and stopping distance is growing. I feel like my family is at risk if there were ever to be a time I need to brake hard or fast. Theire are no warning lamps but obvious excessive braking effort and can feel the brake rotors through the pedal. #2- Intermittently, at low speeds, pulling into parking lots and parking spaces while turning the steering wheel, electrical power cuts out, steering wheel jerks out of hand, and a dash light comes on saying "service stabilitrack". This is a huge safety issue that could certainly cause an accident. I have Googled this very common issue with my...

The power assist for the brakes intermittently goes out and does not work, typically happens at low speed like when parking. The most recent time this started happening a ‘brake assist’ notification appeared on my dashboard. This is a safety concern. I see a recall for my model and year, but when I inquired was told my VIN was not covered. The existing recall number that I believe should be expanded to cover my VIN is recall number N192268490 and is also listed as NHSTA campaign numbers 19V645 and 20V603. Please look into this and expand the recall to cover my vehicle and others that should be covered for this safety defect.

When backing slowly down a ramp with a boat attached the brakes feel like they are not holding . Feels like I'm going to be in the water with the boat. In drive the brakes work just fine. Only when going down a ramp with the boat it feels like the brake is down as far as it will go and fading or out of pressure. This happened a couple times before this in June and July. Then I replaced the front brakes. First time I backed the boat in after brake change it still happened. I feel the power booster or something else is bad. It's just weird it is only in reverse at slow speeds.

I have had several instances when it has become difficult stopping my vehicle, particularly under low-speed conditions like when approaching a stop light or while in a parking lot. I have had to use both feet and all my force to stop the vehicle and several of these times was while towing which only added to the difficulty and danger of the situation. I have replaced my brake pads, rear calipers and flushed the brake fluid all of which has not helped or resolved the issue. A shuttering in the brake pedal often times accompanies this issue, similar to the ABS system activating. I see there is a recall 19V645000 which from my online research seems to mimic what I am experiencing but when I called Chevrolet directly, I was told to make a report on this website. I was not offered any assistance in the matter.

[XXX]. My 2015 silverado with the 5.3 randomly just shuts off. When slowing down and at 10 to 20 mph, the Instrument panel goes dark, the engine shuts off, no power steering or brakes and almost crashed into someone. I turn the key it starts back up, but have to reset time and date and lose radio channels. Once a message about stabilitrac flashed after starting back up. Truck can be for Inspection. This problem happened 4 times in one morning it is being looked at now on [XXX]. There hasn't been any warnings. It just shuts down.

“Service trailer brake system” this message randomly appears with no trailer connected at all, i recently bought a brand new trailer and im scared to tow it since there is no current fix for this error message on the display, it comes on randomly and will not stop popping up and dinging it is a huge distraction as it repeatedly does it over and over, also when it does this you lose trailer brakes which is very unsafe especially in the mountains. This has been a known issue for years that is why i don’t understand why there is only a fix for the 22-23 models. Gm needs to address this issue as there are tons and tons of complaints, it is never safe to lose trailer brakes especially with all that weight you could burn up the truck brakes and cause an accident or if the trailer starts swaying...

Truck often while driving getting a "Service Trailer Brake System" message, that is a safety-critical defect, and in my case, a defective wire harness

Trailer Brake System, needs service light keeps coming on. Have had this issue with this vehicle since I purchased new in 2015. Have had this issue checked by dealer several times and they always tell me unable to duplicate customers issue on my service invoice. The service light will come on and an audible alert will sound for a few seconds and then go off and come back on. Apparently this is an ongoing issue with GM products, have talked to other Chevrolet owners who have experienced same issue and several GM forums have this issue as a priority topic.

2015 Chevy Silverado LTZ 5.3L. 81.2k miles. After not driving the vehicle for four days while away on a work trip, the very first trip out of the garage, the brakes became extremely difficult to press and stop. Originally, it occurred at low speeds, but it persists at all speeds now.

Low speed braking. No warning lamps or messages. When creeping forward and then applying brake boost is lost. Intermittent so the driver may not be able to anticipate when braking will change.

Randomly the brakes get stiff, even while on a hill or stop and go traffic. I noticed the first time after first buying it that while on an exit driveway at a decline, the brakes felt like they slipped or went away. I had to push them hard all the way down and thought I was going to roll into oncoming traffic. The truck soon after was making a noise and felt like it was losing power and revving after the keg was taken out and loss of gas mileage. The dealership confirmed the brakes vacuum pump and the high pressure fuel pump were both bad and the gas was leaking into the oil causing problems and possibly ruining the engine, they stated both would need to be replaced. Check engine light comes on soon after fresh oil changes everytime and codes were shown on computer for running rich. No...

I recently brought my 2015 Silverado in to the local dealership to fix the “increased brake pedal effort” recall. The dealership reprogrammed the brake control module but the problem still persists. Yesterday 03/07/23 I experienced loss of brake power in interstate traffic while traveling at low speed. This happened several times and it is very concerning. I believe the GM vacuum pump is faulty and I will contact the dealership about replacing it.

I was backing up at low speed after a 25 minute drive and went to stop, pushed brake pedal and it was hard and didn’t slow the vehicle. I stood on the pedal to stop from backing through my garage door and wheels made a dragging sound and stopped. Put it in drive to check the brakes and same thing happed, brakes hard and no stopping power. Put truck in park and shut it off. Started it back up and brakes were fine.

Hard brake petal at low speed when I'm trying to park vehicle, dealership kept truck for five days, service Rep said, he couldn't get to my truck,. I picked up my truck and I took it to another Dealership they claimed that my brakes problem was completed, Matick Chevrolet Jan 6, 2023 . Problem # ,2 High Pressure Fuel pump needs replacing as per Matick Chevrolet inspection on 1/6/2023 their Mechanic inspected my truck , I have their invoice stating that and two more invoices from ,one from Pep Boy's diagnosed bad Fuel pump and another invoice from Good Year Tires diagnosing bad High Pressure Fuel pump is bad with 45 psi. Pep Boy's also diagnosed my Brakes Vacuum Booster Pump needs replacing and remove and replace another Brake Booster vacuum pump and they listed two different parts numbers, #3 my Electrical System causes my dashboard monitor to jump back...

Inability to brake at low speeds. Brake vacuum pump failing at 100K miles. I can submit photos and report later.

While driving at low speeds (approx 5-10 mph) the brake pedal became stiff and very difficult to stop. This issue happened with no prior warning or indication of the issue. As a result of this issue severe damage to personal property housing and vehicles was nearly missed. Upon research this has been a common issue for GM vehicles specifically trucks and SUVs.

I constantly get a trailer assist brake service warning dinging. I have video. I paid for a tech to fix it but it still dings. I fear the brakes will be affected since it says "Service Trailer Brake System." System has not been inspected by Dealer because they told me it could take 6 months to get it in due to high volume of repairs on books and low inventory. This started in 2021 and stopped after I paid a tech to fix it for about 6 months but started repeating the problem again in 2022.

Anytime I pull into the parking lot and I have to pump my brakes more than once the brake pedal stiffens up and the truck does not stop it has almost caused a collision and almost went through the window of a business it is to the point where every single time I drive it does this from what I heard it is the vacuum pump it does not provide enough vacuum for the brake booster so the brakes do not work it cost about $250 for the OEM part and that is not guaranteed to work the problem will persist later on down the road after more mileage put on the truck

At slow speeds the brake pedal gets hard and does not stop vehicle. At random times I temporarily lose power steering and vehicle is hard to turn.

Losing power brakes at low speeds. Narrowly avoided rear-end collision.

The vacuum in the braking system failed and would not stop the vehicle especially after going over 1500 rpm the vehicle would stop, but if you had to brake without being able to go above 1500rpm the brakes failed. You had yo put a lot of pressure on the brake pedal to slow it down and stop. When you have a hill to go down it could be very dangerous. Taking the vehicle on 11/15/22 to Kendall Chev I'm Marysville, WA. No warnings were given on brake problem. Since truck will not stop normally, any person, vehicle, bike, etc is in danger of being in front of truck because of brakes failing.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated while driving 45 MPH, he heard an abnormal noise coming from the vehicle. The contact stated no warning light was illuminated. The contact stated that he continued driving to his residence. The contact stated while leaving the driveway, he continued to hear the abnormal noise, and the service brake warning light illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the brake vacuum pump to be replaced. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 18V578000 (Service Brakes, Hydraulic) however, the VIN was not included. The manufacturer had not been informed of the failure. The failure mileage was approximately 106,000.

Trailer brake assist warning keeps going off at different times with no trailer attached. Quite annoying and unsafe distraction.
