general problems of the 2015 Chevrolet Silverado 1500 - part 1

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 told me to contact this government agency. In order to prevent fatalities of innocent lives, I am reporting this.

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 n182202780.

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.

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.

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.

Pulling forward in my driveway and my breaks went stiff.

-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 looked at it or not. Quality did file a claim for it though. - there was no warning, indication, message, problem before this happened. My brakes were were working and then they weren't.

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.

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 a requiring issue from complaints on this make and model of truck.

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.

The vehicle was taken to a dealer however, the failure was not duplicated. The manufacturer was not notified of the failure. The failure mileage was approximately 145,000.

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.

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.

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

Brakes are hard at low speeds.

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 .

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.

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.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that on several occasions while driving at various speeds, the brake pedal was depressed, and the steering wheel pulled to the left. The eps, abs, and check engine warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the eps module needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.

“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 you can not correct it with the breaks.
