Problems with 2015 Chevrolet Silverado 1500 SERVICE BRAKES

On average, the 2015 Chevrolet Silverado 1500 starts to “feel” problems with the SERVICE BRAKES and its various aspects after 64 772 miles.

Recently reported SERVICE BRAKES problems on 2015 Chevrolet Silverado 1500

The brakes occasionally will get hard when depressing at a low speed and fail to work. this usually happens coming to a final stop in my driveway that is down a slope after i have already been using the brake to slow down some. the vehicle is barely moving when it happens. it has happened a couple of other times going down a slope in our subdivision entrance applying occasional brake pressure at about 20 mph. i had it diagnosed by the local chevy dealer and they said the vacuum pump and seal needs to be replaced and the brake system flushed. total estimate for the work was $970 which i did not have done. i noticed online that others have had this same issue.

Brake failure at low speed. while sitting in stop and go traffic, the brake pedal reacts as if the vehicle isn't running. pedal seems high and hard then soft and low. vehicle will stop with extreme pressure on pedal.

Yesterday (18-mar-2019), i was pulling into a parking space at a restaurant and all of a sudden when i tried to apply my brakes on my 2015 chevrolet silverado 1500 crew cab, the pedal was extremely hard to push. the truck continued moving after i exerted as much force as i could on the pedal. luckily the curb assisted in stopping the truck before i crashed into a wall as i had my two young children in the vehicle with me at the time. i am also glad my wife was not driving the vehicle at the time. i don't believe that she would have had enough force to stop the vehicle under the conditions observed. no warning lights came on before, during, or after the incident. the symptoms match those reported under bulletin pit5361 regarding a known issue with failure of the brake vacuum pump. i purchased the truck new in august 2015. the truck has about 51,000 miles on it.

Break vacuum pump breaks get hard at low speed making the the vehicle hard to break when making a stop or in an emergency stop and when trying to slow down

Going throught down town traffic and the brakes would not work. it felt like i was pushing on a brick. then had to use emergency brake in traffic for two hours.my boss has same truck as i do and one week later had the same thing happen except he hit the wall at his home. i have spoken with several other employees and all have experienced this problem. it cost about 800 dollars to fix it

While backing into paved boat ramp at 1.5 to 2 mph brake pedal became very hard and had to press pedal as hard as i could in order to stop truck. "truck was on level ground and i was turning steering wheel slowly". i pulled out of ramp and problem repeated when brake pedal pressure was applied and removed and then reapplied. problem continued to reoccur after trailer removed from truck and brake pedal pressure was applied and removed them reapplied. truck was looked at by dyer chevrolet the next day. chevrolet is aware of issue as tech heard my description and he stated there was a bulletin from gm on it but it was not recalled. after receiving estimate later that day from chevrolet i decided to take truck to another repair facility that estimated repair $500 cheaper than chevrolet dealer. repairs were made following the gm bulletin and using gm parts from the chevy dealer for $1139 as opposed to dyer chevrolet wanting $1662 for a issue that needs to be recalled. a quick internet search indicates that many others are affected by the issue as well. it is my hope that you may be able to help as i am sure this will occur again as gm has not changed anything they have merely charged the customer to put a bandaid on a problem they engineered. the mechanic that ultimately repaired truck stated gm knows they have problem as they only used that booster pump on 2015. there is no way a 50000 mile truck should have this issue. please see attached documents from chevrolet dealer that describe issue of mechanical failure of vacuum pump. how is it not a recall issue if vacuum pump may pump motor oil into brake booster? this should not happen and is not a normal wear and tear issue. this is a engineering failure. i look forward to helping any way i can to get this recalled. contact me as needed. shame shame shame on gm

Went to go use my brakes and noticed they got really hard and almost hit someone. i towed it to the dealership and they said it was a faulty vacuum pump, belt, etc..i had asked if this was recalled they said no .told me it was going to be 1600 to fix. i went home and did a little research apparently this is an issue. 2015 chevy 1500 65k miles

Tl* the contact owns a 2015 chevrolet silverado 1500. the contact stated that the brake pedal became stuck while reversing out of the driveway. the contact had to apply more pressure to the brake pedal than usual to slow down the vehicle. there were no warning indicators illuminated. the dealer was not contacted. the vehicle was taken to an independent mechanic who diagnosed that the brake booster needed to be replaced. the contact planned to have the mechanic repair the vehicle this week. the manufacturer was made aware of the failure and provided a case number. the failure mileage was 44,000.

Low speed brake issue- braking effort increased considerably and vehicle and caused become difficult to stop. while parking vehicle in private parking lot the brake pedal became very firm with no take up and took considerable effort to bring the vehicle to a stop. immediately brought vehicle to mechanic who informed me that the problem was failing brake booster and that it is a common defect with this make model of vehicle. also informed me that the when the booster begins to fail can deposit contaminates in the oil system that can prematurely damage the engine. a internet search produced a long list of customer with similar vehicles describing their experience of similar issues. i called the local chevy dealer and they also informed me that is common issue but there were no recalls or manufacture announcements on the vehicle so they would not reimburse for the repair. i contacted gm and they logged my complaint gm case #[xxx] but they would be unable to offer any repair assistance at this time. will repair vehicle at my own expense. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tt

I have a 2015 silverado 1500 5.3 with about 90k miles. while i was parallel parking, after the 2nd pump, i realized the truck wasnt stopping. i had to use both legs to make it stop before hitting the car in the back of me and almost crushing a pedestrian. my brake pads and rotors are fine. i do hear an abnormal noise coming from the engine area at all times. kinda like a bad pulley bearing or something. noticed it the day the truck started acting up. i looked online on mutiple websites and understand this is a common problem with the vacuum pump, brake booster and master cylinder. this should be a safety recall.

Braking assist service warning message appeared on screen. noticed braking assist is not working at low speed and idle. requires significant foot pressure to have brakes work. no accident yet.

Brakes fail at low speed. problem diagnosed by chevrolet dealer and determined to be the same problem as outlined in chevrolet technical service bulletin pit5361b. gm not covering repair as they claim nothing is wrong and the vehicle is out of warranty.

When at a slow rolling speed brakes are extremely hard to brake, mainly when in parking lots or backing my boat in the boat ramp its extremely scary and seems like the truck wont stop rolling. this is so unsafe and scary. its almost like the brakes dont work. but im pretty sure its the vacuum pump brake system.

I've experienced the same issues that numerous people are reporting and also received the letter from chevy/gm in regards to the brake failure at slow speeds. i've had this issue occur at least 3 times in the last couple of years. didn't realize it was as big of a known problem until conducting additional research. want to ensure my voice is heard/known in the larger complaint that is developing. a recall should be issued. this is a scary situation when this occurs. simply turn off truck and start it up again and the immediate problem goes away. however the issue occurs without any warning and could definitely lead to an accident.

Brake pedal too hard..sometimes dont brake have to put both feet to brake

When attempting to brake, i pressed the brake pedal with appropriate force only to find that there was a loss of brake power... i would equate it to 85-90% brake loss. i was able to apply pressure as hard as i could and the vehicle stopped over double the usual stopping distance. i did end up going through the stop sign and was thankfully not hit. i pulled over and restarted my truck, i applied pressure to the brakes and all normal pedal feel has been restored.

When travelling at low speeds, the brake pedal pushes all the way to the floor and does not fully stop the vehicle. on 3 occasions now, i have had problems stopping the truck while parking, coming very close to hitting another vehicle.

Tl* the contact owns a 2015 chevrolet silverado 1500. while driving 20 mph, the contact depressed the brake pedal, but it failed to engage properly. in addition, the abs warning indicator illuminated. the contact had to pump the brake pedal three times to stop the vehicle. the vehicle was taken to an independent mechanic, but was not diagnosed or repaired. viva chevrolet (5915 montana ave, el paso, tx 79925) was contacted and stated that the contact would be responsible for the diagnostic and repair costs. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 91,000.

My truck brakes normally except when i stopped, then at low speed the truck fails to stop. i've almost gotten into multiple accidents (hitting walls, poles, a bus) and its even worse going downhill. it takes both feet and all my weight to get the truck to stop. eventually someone is going to get into a bad accident because of this issue. happens when going forward and reverse. i've read several articles about it on the internet and i've talked with gm techs and it's a bad problem with the vacuum pump. please help!!!!

The truck is intermittently hard to stop, i believe it is losing vacuum. i've had a mechanic look at the truck and they cannot find anything wrong. this is intermittent and i'm scared to drive the truck. this only seems to happen at low rpm. i believe this should be investigated because the issue could cause an accident. i'm a 235 pound male and i believe a smaller person would have even more trouble stopping with the sudden loss of vacuum. i read in a forum that others are having the same issue and i should file a complaint. had it not been for the article that mentioned the nhtsa i would have never filed a complaint. i have to think there are others dealing with this issue and aren't sure where to turn or report the issue. please help.

Noticed hard brake pedal on top when stopping. dealer tech said brake vacuum assist pump needs replacing. less than 75,000 miles - not covered by warranty

Tl* the contact owns a 2015 chevrolet silverado 1500. while reversing out of the parking lot, the contact attempted to depress the brake pedal; however, they failed to respond. when the contact made a second attempt, the brakes responded and the vehicle stopped. there were no warning indicators illuminated. the contact took the vehicle to an independent mechanic where it was diagnosed that the brake vacuum failed and needed to be replaced. the vehicle was repaired, but the failure recurred. the dealer and manufacturer were not notified. the failure mileage was 62,000. the vin was not provided.

When slowing down to park, i lost braking and could not stop the truck. i had to put the truck in park to stop the momentum. this happened going in reverse. when taken to dealer i was charged $470.96 for parts and labor at n the vacuum pump which provides power for braking and steering.

When coming to a stop in traffic the brakes failed to stop my truck. i was going straight at a very low speed. the pedal felt like i was pushing on a brick. i did get my truck stopped and got it off the road. i called my dealer who said they had not heard of this problem but thought it sounded like a brake booster failure. i called gm customer service who started a case # 9-5055710889, they told me that the truck was out of warrenty. upon further reading i discovered the tsb for my truck to replace the brake booster, master cylinder, line , and vacum pump. the truck is being repaired now. my truck has 41,000 miles on it.

Driving newly purchased 2015 chevy silverado 1500 at 35-45 mph on freeway (which has a 65 mph speed limit). traffic ahead was slowing down, and the brakes were pressed, speed was reduced, but when the cars in front (with at least 5 car lengths of space ) suddenly stopped, and i slammed the brakes, the brakes failed. i tried and tried pressing the brakes, but the truck didn't stop, and i rear-ended the vehicle in front of me, which ended up rearing the vehicle ahead of it, and so forth. due to the brakes not responding, i was unable to stop like the rest of traffic, and thus, caused an accident. (note: the weather and road conditions were fine, not went road, as stated on police report.)

While at low speeds mostly backing my vehicle loses braking. the pedal goes to the floor however the vehicle continues to roll.

At low speeds the brake pedal intermittently gets hard and makes it difficult to stop. it seems like there is no power brakes. usually happens when parking. this has happened about 5 times.

Brake suddenly became real hard and i couldn't stop the vehicle. i had to press real hard to get it to stop. i ran into the middle of the intersection at a red light fortunately no cars were close to that intersection at that time01

Tl* the contact owns a 2015 chevrolet silverado 1500. while driving at a low speed, the brake pedal became stiff and the brakes failed to respond in a timely manner. the contact had to depress the brake pedal several times to stop the vehicle. the failure was experienced several times. the vehicle was taken to healey chevrolet (5216 ny- route 17m, new hampton, ny 10958, (845) 360-9821) where it was diagnosed that the brake vacuum pump was leaking oil. the vehicle was repaired and the vacuum pump was replaced. the manufacturer was contacted and stated that the vehicle did not qualify for the manufacturer's brake vacuum pump replacement because the mileage exceeded 72,000. the manufacturer provided case number: 95212761589. the failure mileage was 94,000. *bf *jb

As my wife came to a complete stop at a stoplight and as the light turned green, she pressed the gas pedal and the truck would not accerlate. she pressed the gas pedal down to the floor board and still would not accerlate. so due to this the truck slowly rolled foward. she slammed on the brakes and the brakes would not move. like if they became locked and wouldn't move an inch. at this point she is trying to get off the road to the shoulder, to avoid oncoming traffic. then she finds that the steering wheel is also locked and can not be turned. it's taking her maximum effort to stop the truck from rolling forward and to veer off the road to avoid other vehicles. she is finally able to stop the vehicle after about 100 yards of effort and waits about 10 minutes, before the brakes and steering wheel would free up. no error message was present the entire time these functions were disabled and after they freed up, it was like if nothing ever happened. no check engine light has ever been on this vehicle. strong belief this is a manufacturing defect and should have a recall.

Brake pedal becomes hard to press when frequently stopping, such as backing up a trailer or in stop & go traffic. this has nearly caused me to have an accident more than once. it is becoming progressively worse and more frequent there are no fault indicators or codes displayed. it will start working again and then start randomly in traffic.

On several occasions while backing down a sloped driveway while depressing the brake, the pedal has become hard to push and braking was almost impossible. this same problem has occurred while backing a trailer, it takes a greater applied force to depress the brake.

On two occasions in the past week my brake pedal has become extremely stiff at low speeds and caused the brakes to fail. the first incident occurred as i approached a stop sign on a busy city street. my brake pedal became stiff and the brakes would not stop the vehicle. causing me to roll into the path of another vehicle. i managed to stop and the other vehicle avoided me. the second incident occurred this morning as i backed into my drive way. as i attempted to stop my pedal became stiff and the brakes would not function properly. despite stand on the brake pedal i was unable to stop my vehicle before it struck my utility trailer. thankfully no damaged occurred. i contacted the parts department at mission chevrolet in el paso, texas and was advised the part is in heavy demand and will be unavailable for 7 to 10 business days.

Brakes became very hard when trying to stop at slow speeds. have to apply very hard pressure to get truck to stop. several very close calls running into another vehicle.

My truck would brake normally except when i stopped, then at low speed the truck would fail to stop. i almost got into multiple accidents (hitting walls, poles, a bus) and was even worse going downhill. it took both feet and all my weight to get the truck to stop. my dealer said the vacuum pump was at 11psi when it should have been 27. eventually someone is going to get into a bad accident because of this issue.

Tl* the contact owns a 2015 chevrolet silverado 1500. while driving 15 mph, the brake pedal was depressed and failed to operate. as a result, the vehicle crashed into a tractor trailer. the air bags failed to deploy. a police report was not filed and there were no injuries. the contact was able to park the vehicle. the contact called gengras chevrolet at (860) 748-4355 (585 connecticut blvd, east hartford, ct 06108) and was informed that they were unaware of any brake failure. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 68,000.

When driving at low speeds and the brake pedal is depressed a few times the brake pedal gets very stiff and will not come to a complete stop if needed immediately.

I was parking my truck in a parking lot space, and when the truck was moving slow, i applied the brakes, and had to push very hard on the brake pedal to get the truck to stop. i had a local dealership run a diagnostic on the truck, and it came up as a faulty brake vacuum pump.

Brake vacuum pump failed while on the freeway causing brake pedal to be unresponsive almost causing major accident. this is listed as under investigation. there was no warning or light. brake pedal instantly became stiff and could not be pressed down. chevrolet fixed this by replacing only the pump. it's recommended the vacuum lines and brake booster be replaced too due to potential oil leakage which states will cause pump to fail again. chevy did not replace additional parts for me.

When having to apply the brakes repeatedly, slow traffic, stop lights, backing a trailer. the brakes become extremely hard to push and do not function. exceptionally dangerous backing a trailer down a boat ramp or in stop and go traffice. this has happened numerous times over the past year

When traveling in stop and go traffic, the brake pedal gets very hard and you can not stop the vehicle. this happened to me 3 times too many, i had the vehicle towed to the dealership, $709.00 later, they supposedly replaced the vacuum pump. dealer stated they have had other vehicles brought in for the same reason. this is a serious problem.

Tl* the contact owns a 2015 chevrolet silverado 1500. while driving approximately 50 mph, the brake pedal became really stiff and did not function. also, the brake assist failure indicator illuminated on the instrument panel. the vehicle was driven to the contact's residence and later taken to classic chevrolet of sugar land (13115 southwest freeway, sugar land, tx 77478). the dealer determined that the vin was not included in nhtsa campaign number: 18v578000 (service brakes, hydraulic) and the repairs had to covered by the owner. the manufacturer was notified of the failure. the vehicle was not repaired. the approximate failure mileage was 117,000.

It would roll even with the foot on the brake at low speeds faulty air pump had to get air pump, tube, air pump belt,alternator belt, air condition belt that cost me $700.

At low speeds (such as in parking lots, at traffic lights, stop and go traffic, ect.) i lose brake assist, making it extremely difficult to stop.

Driving down single lane road i began to stop for red light, as i began to depress brake pedal but it was stiff and had significant effect slowing my truck. i drove of right side of road into wet grass too avoid collision of suv stoped in front of me. there was no loss of control or damage done to exterior of truck or myself . as i'm almost completely stoped the side curtain air bags deploy for no apparent reason causing sever damage it the interior panels, headliner and both front seat belts that have that contain small charge permintly lock and now are un usable.i was only person in truck but the passenger front seat belt is retracted and locked guitar string tight.

I have a 2015 1500 silverado and it is having brake issues. the peddle becomes hard to depress and the truck will not come to a stop. i have noticed this several times coming to a stop at low idle on the street. i dropped it off at the dealership only for them to tell me it would be $1100 and gm did not have a recall on it. they said the vacuum pump and several other things would need to be replaced in order to fix this.

On 12/15/2018 my brake vacuum pump went out. i had it replaced at a dealership. total cost $1506.56. master cylinder, brake booster, and a connecting pipe had to be replaced also. april 2019, i receive a letter from gm, describing this issue and saying if i have less than 72,000 miles or bought it new within the last 6 years,whichever come first, they will fix it. brakes are a very serious component. this problem dates back to the 2014,s. i feel gm should reimburse me for my repair cost, since the problem came from their plant. i have more miles on my truck than they say they will cover. brakes and the components are things they should cover. i have invoices and proof that i paid these expenses. every person pays hard earned money for a new vehicle. manufacturers should be required to back their vehicles. i was driving on a side street when this pump went out. i had all i could do to stop it, using both feet on the brake pedal. thank you for your time.

At low speed in a parking lot or in out of a parking spot the brake pedal intermittently becomes excessive and non-functioning. vehicle needs to roll to a stop on its own. once stopped and put into gear pedal functions again. this has now happened 4 times in the last 6 months. after doing a search online i see a number of other owners have reported this issue. seems to be a bad vacuum pump. wanted to report it as well hoping it will lead to a safety recall.

When i go slow the break pedal get so hard i can stop

On several occasions the brakes stopped working correctly. the brake pedal became extremely difficult to push down and would not stop the truck within the normally expected stopping distance. most of the time the brakes worked perfectly fine - this issue seemed to happen randomly, but after it happened enough times i realized it was only happening at slow speeds. it happened to me in a couple parking lots, the drive-thru at mcdonalds, and while backing up a trailer. these incidents were separated by many months, with the brakes fine in between. it wasn't until i received the service bulletin letter from chevy that i fully realized what was going on. i immediately took the truck in for service and the technician was able to verify the problem. they replaced the vacuum pump and the brakes have been fine since. chevy would not cover the cost because i was beyond their 72,000 mile limit (although the problem first started before i was at that mileage), so i paid $561 out of pocket to have the new pump installed. i feel this is a serious safety issue that should be addressed with a recall. i realized the seriousness of it the last time it happened to me which was when i was backing up the trailer for my kids boy scout troop and found myself unable to stop quickly. i had to leave the trailer where i got it to stop instead of where we were trying to place it.
