Whenevr i back the truck up at slow speeds, the brakes temporarily fail for approximately 1-3 feet. coming to a stop at slow speeds can also cause the truck to take extra distance to stop. i have changed to new brake pads, turned the rotors, and purchased new tires. the truck bounces severely when traveling at speeds over 50 mph on concrete roads. only on concrete. asphalt has normal ride as soon as the road transitions then the truck bounces.
Purchased used 2015 silverado ltz with 87k miles on 12/1/2018 from dealer. on 12/2/2018 while backing out of parking space for first time, brake pedal would only move 1/4 inch with great effort (80-100lbs effort), and only applied enough braking force to stop truck moving 2 mph over 5 or 6 feet. was able to immediately recreate problem moving forward while under 5-6mph, each time taking roughly 10-12 feet to stop with great braking effort. problem occurred again 12/3 after a short trip (3 miles, 40mph) while slowly backing into parking space. put truck in drive and the brake problem persisted. backed up again, problem persisted. maximum braking force would not stop truck from rolling down 7% grade from dead stop. maximum braking force will absolutely not stop truck in stop-and-go traffic when this problem occurs again. **** must drive in far right or left lane to ensure space to swerve into when brakes fail to avoid collision. **** extreme safety hazard - will cause accidents, injuries & property damage. this needs to be a recall asap.
I was pulling into a parking spot and when pressing the brake pedal to stop it got really hard, had no brake pressure to stop, thankfully i had no concrete barriers or light posts in front of me to cause any damage just grass on a hill to help me stop. second time this happened i was backing up to my garage that was on a slight hill and the brakes got hard but i was able to stop by putting the truck in park and using my emergency brake. third time i was driving down the highway going approximately 65mph as i was slowing down to get off of an exit i noticed my brake started to get hard thank goodness i have a tow haul botton and i used that to help me slow down to get off the exit. everytime my brakes have gotten hard is when i have to back down a hill, pull down a hill, park in a parking spot or have to press the brakes constantly to slow down.
Brake pedal in the truck will occasionally go to the floor when the truck is in reverse. the problem seems to happen more when backing a boat trailer down a ramp at a boat launch where the truck is at an angle. have lost brakes multiple times when doing that. fluid is full in the reservoir and the mechanical portion (brake pads, rotors, calipers) checked out as fine.
Brake peddle randomly becomes hard to push and will not stop the vehicle after otherwise normal functioning. this occurs generally at low speeds in forward and reverse. this has occurred on numerous occassions but randomly
At low speeds while in motion either in traffic, driveways or parking lots the power brakes would stop working causing the truck to not brake properly. the brake pedal became very stiff and would not stop. while this did not cause any accidents, it was a near miss on several occasions. i took it to the chevrolet dealer where they said the brake "vacuum pump has failed". they stated it was not covered under warranty and would cost $700.89. the pump was replaced on 11/28/2018, with no occurances of this issue since. the truck had 59,108 miles on it at the time of vacuum pump replacement. the first brake issue was around 50,000 miles and happened about 8-10 times between june and november 2018.
Truck has become very hard to stop latley. brake pads look new. dealer says nothing is wrong. almost rear ended multiple cars this month. thinking of just trading it in on a ram. truck doesn't want to stop!!!
While backing up when brakes are applied the pedal has very little travel and is hard to push down causing vehicle to continue backing with little stopping power or effect. this takes effect only when backing after restarting vehicle. system checked at firestone tire center and result indicated brake vacuum power was not working properly. this occurs almost daily when backing up.
At low speeds i have no breaks and the pedal is rock hard. zero to 1/4' of movement and the truck will not stop. i nearly hit someone.
Breaking system vacuum pump failure. common and known problem. brakes sporadically require substantially more effort to slow vehicle and increases breaking distance significant with no warning. increases likelihood of crashes. mine failed while driving 30 miles an hour on an exit ramp almost causing a collision. gm refuses to cover this under warranty and despite knowing that this is a common problem, has not issued a recall.
At low speeds my brakes are very hard to press. the pedal gets really tight and will not press down. the longer you try to press the tighter they get. the truck will barely stop before i almost hit something. does not do it every time, but it seems to be more frequently. it seems to happen when i go from a stop, then accelerate slowly and then try to slow down to a stop (ex. when parking).
2015 silverado 1500, 4x4, 41,000 miles on odometer. at slow speed on city street driving straight (under 5mph), complete loss of all power assistance of brakes. driver needed to apply extreme manual pressure at pedal to get the vehicle to stop and not roll into the car in front of it. immediately parked, came back issues persisted in parking lot, but then went away when after speed of approx 10mph reached. no warning lights or display indicators triggered during incident. issue has not occurred again. (approx 70 miles since issue first occurred)
I was coming off a hill and trying to brake before making a turn onto another road. the brake pedal would not depress, felt very hard and i was unable to stop the vehicle. i took the truck to a garage and was told it was a fault in the brake vacuum booster and master cylinder. i will attach the invoice for the parts. the truck is still getting fixed and do not have an invoice for labor yet.
Noticed failure of vehicle to stop. lack of power assist braking at slow speeds. brake pedal is rock hard with little to zero travel (1/4' at most). vehicle will continue to move (regardless of pressure applied to brake pedal) for several feet. while this has occurred in both forward and reverse gears; the issue is consistently observed in reverse.
Was pulling into a parking stall slowly and truck would not stop when applying the brake pedal. brake pedal was very hard to press and used both feet to press on the pedal to eventually make the truck come to a stop. caused a minor (cosmetic) scrape on passenger side front bumper (scraped concrete wall) due to the inability to stop when brake were being pressed.
Just experienced brake failure while backing into parking space at low speed truck has just turned 40,000 miles. brake pedal was hard to depress as if the ignition was turned off. not the case engine was running and brakes were applied with extreme pressure and finally was able to stop vehicle before i bounced off of curb. i understand chevrolet is aware of this and there is some class action law suits out there. a tsb has been issued but, from all the forums i have read this does not correct the problem. i will take into dealership as soon as possible if it don't kill me first. help
While backing up from drive way tried braking to stop and truck continued to travel almost hitting a vehicle that was parked on the street. the next day before taking the truck to the dealer to have it inspected made a stop at the gas station and again the truck would not stop. dealer diagnose bad vacuum pump and oil in brake booster and lines ,all needed to be replaced costing over $1,300 dollars.
When pumping brakes to stop, on the second to third pump the pedal gets rock hard and vehicle very difficult to stop. loss of vacuum pressure seems to be the issue. in the gm dealer now, telling me the vacuum booster defective
Noticed brakes seemed to stop working properly at low rpm.happened while backing out of driveway. also while sitting in traffic at redlight.
Vacuum pump for brake system and hose/tube that connects to the pump had to be replaced after i lost brakes completely while driving the vehicle with my two year old daughter in the back seat!! the vehicle had to be towed to auto repair shop. mileage was at 55,096. this happened while in a drive thru line at chic fila. brakes got very hard and i just kept rolling into vehicle in front to me. i stopped rolling just short of hitting the vehicle. i slowly went through the line to park the vehicle in the parking lot and the brakes were completely rock hard the entire time. i had to simply roll to get where i needed to park slowly.
Vacuum pump. my vacuum pump went out as i was driving home on the highway. every few presses of the brake pedal it would go all the way to the floor and it took much longer to stop. it was scary and i am very thankful i didn't get in a wreck. i got it fixed at my chevrolet dealer. the cost for repair was $600. worst part is my vehicle, a 2015, ony had 27,000 miles on it. still feels new and the brakes failed.
I brought my 2015 chevy silverado 1500 to a local repair shop as my brakes were not functioning properly. stopping required very forcefully depressing the brake pedal to stop. on november 7, 2018 the repair shop contacted the local chevy service manager to determine if there was a recall on the vehicle given that the vehicle is a recent model with limited mileage. it was determined that master cylinder and brake booster were defective and needed to be replaced. after taking a lengthy drive the vehicle had same brake problems making it extremely difficult to brake going down a hill. the vehicle was taken back to the local auto repair on november 15th. repair shop called local chevy dealer and spoke with parts manager to see if there was a recall on recent model chevy silverado as they had a 2016 silverado in there shop same day for same problem. chevy dealer parts manager indicated there was not a current recall but they did notice an issue as they had sold 10 abs pumps in just one week! the local repair shop replaced the abs pump. the defective brake equipment placed my family at risk and cost me more than $900. most importantly this defective brake equipment in the recent model chevy silverado is a significant safety issue. had there been a need to stop quickly i feel confident i would not have been able to avoid a collision.
Sudden loss of brakes while slow speed maneuvers such as turning and parking. brakes either become very hard to depress or depress to floor. very dangerous! chevrolet has a tsb out because it is a known issue but has yet to be recalled. most likely due to the expense related to the repair.$1500. please address. please reference chevrolet's technical service bulletin (pit5361b) for more information.
Loss of braking at idle speed brought t ok desler ghey replaced multiple components extended warranty covered all but $100
Tl* the contact owns a 2015 chevrolet silverado 1500. while driving at a low rate of speed, the brakes failed to operate without warning. the contact had to place the vehicle into park in order for the brakes to function properly. the contact took the vehicle to modern chevrolet of burlington (2616 alamance rd, burlington, nc 27215, 336-229-5501) where they replaced the vacuum pump and belt. the vehicle was repaired at the contact's expense. the manufacturer was notified of the failure and informed the contact that they could not assist because the vin was not included in a recall. the failure mileage was 68,000.
When traveling at low speeds after truck had been in use for 2.5 hours, brake pedal would suddenly become very hard to depress and brakes would not stop vehicle for approximately 5 feet. condition present in both drive and reverse. happened on 4 occasions, all after 2.5 hour trips. mechanic has found defective brake vacuum pump and brake booster after researching the issue and finding out that this is a common problem.
Loss of power brakes at low speed when backing into parking spot. 4 occurrences since october 2018 under exact same circumstances, checked by dealer, no work done but tac case opened.
I was driving in rush hour traffic and i went to hit my brakes and the pedal was hard and the truck would not stop. i put my flashers on and went very slow to the next exit. i went to park the truck at the hotel i was staying at shortly after exiting highway and as i was in reverse backing into a parking spot again the truck had a hard brake pedal and would not stop. i didnt hit anything thank got but it scared me pretty good. i carpooled with a coworker for the rest of that week while we were out of town for work. i ended up driving the vehicle home about 3 hrs away friday evening and had no problems with the brakes. i have not driven the truck much since this has happened and since i had seen many others have had the same problem. the truck goes into the dealer 11/27/18 and hopefully they will replace what needs replacing. i bought this truck 9/26/18 with 21,000 miles roughly and the truck now 25,773. the truck is a certified pre own vehicle if that matters.
Tl* the contact owns a 2015 chevrolet silverado 1500. the contact stated that while driving at 7 mph, the brakes pedal was depressed and failed to respond as the abs warning light illuminated. as a result, the contact was still going 7 mph and allowed the vehicle to stop on its own. the contact turned the vehicle off and restated the vehicle to resume normal operation. the vehicle was taken to the dealer allen turner chevrolet (4150 s ferdon blvd, crestview, fl 32536, (850) 398-4105) where it was diagnosed that the brake vacuum pump failed. the vehicle was not repaired. the manufacturer was not made aware of the failure. the failure mileage was 35,000.
At low speeds, the brake pedal becomes very stiff. it is hard to stop vehicle. it happens in forward and reverse.
Multiple times at low speeds, usually parking or in stop and go traffic, i lose all braking power. it's terrifying when it happens. i have to put my full body weight (i'm a 200lb male) on the brake pedal and i mean i barely can bring it to a stop. luckily i haven't hit anything in the time it took from the first occurrence of the problem until i could afford to get it fixed. the problem was figured out to be a bad vacuum pump. from what i can tell online, this seems to be a very widespread issue with not many owners reporting their problems. this is very dangerous, i couldn't imagine that happening at high speed, as reported by others. it's almost impossible to stop the vehicle when the brakes do that. just trying to help prevent serious accidents.
At low speeds the brake assist does not work, and there is a momentary loss of brakes.
I 'am having trouble with my brake pedal getting hard when i come to a stop or when parking , at a stop sign , anytime i 'am at a stand still the pedal will get hard on me. this is a safety hazzard to me because if your not paying attention you could hit the car in front of you or behind you. this happens all the time !!!
During stop and go traffic or repeated braking applications my truck loses braking power. seems to be a vacuum issue. almost had a collision in a parking deck.
Having issues with braking at slow speeds, specifically during backing up. when i took my truck into the dealer for routine oil change i had them look at the braking problem and was told my brake vacuum pump is going bad. i saw an article about this same issue being under investigation for possible recall and wanted to make sure my voice was heard.
I was driving at slow speed driving straight while parking my truck and the brakes became rock hard and could barely stop which i came inches from hitting the car in front of me. i was traveling under 5mph just coasting with my foot off the gas and when i hit the brake nothing was happening which i had to put a lot of force to just barely stop my truck in time. the dealership i visited told me the vacuum pump for the brakes was going out and replaced it since i have a 4 month old baby and need a reliable car. my truck only had around 50k miles on it and all the chevy cars my family has owned have never had an issue with brake boosters or vacuum pumps. apparently this is a common enough problem that chevy has a bulletin for hard brake pedals during low speed. running a search online for this issue comes back with many people having the same issue and quite a few having repeated repairs with the problem only recurring. the brakes are not just hard but pretty much non functional when this issue occurs and really is pretty scary when i am driving around my baby that this could happen again with no warning. for such a key component of vehicle safety, this issue really needs a close look and a recall to remedy this known defect. there is no reason this component should go out in a 3 year old truck.
When reversing the breaks were very stiff and the truck would not stop like it should and almost ran into another vehicle.
While driving into town from a weekend trip, when trying to stop for a red light from the highway, the brake pedal immediately became stiff and wouldn't slow the vehicle. it required both feet pressing down hard on the pedal in order to stop the vehicle in time. after turning off the truck and restarting it, the brake pedal released its pressure and i was able to drive normally. however, when coming to a stop to back into my garage, the brake pedal again, was under pressure, and would not stop my vehicle unless excessive force was applied. i was able to stop the vehicle, just feet from the wall in the alley. i believe this is a major safety concern. luckily, i didn't have any issues while going 75 mph on the highway, or i probably wouldn't be able to write this. i was able to get the vehicle towed to my local chevrolet dealership and was told they the vacuum pump was the cause of this issue. after having to shell out more than $700 on a part for a truck that's a 2015 with 63,000 miles with no other issues, is ridiculous. this is a major safety concern while operating the vehicle, and it should be covered by chevrolet. this isn't a part that should fail on the vehicle.
My truck is 3 years old i have 39,500 miles. the vacuum pump has went out and i lose the ability to brake at times luckily my hill assist prevented me from rolling down a hill. second time happened was in heavy traffic was able to pull off side of road before i rear ended another vehicle. there are numerous reports online with this affecting 2014-2018 models. took to dealership this is a $700 replacement charge.
Brake assist keeps popping up on info screen. there's a delay in braking while parking and when climbing steep grades in 4 wheel drive.
Brakes failed exactly as described in nov 26 consumer report article and exactly as currently being investigated by nhtsa. brakes failed while in motion at our local transfer station (dump) while turning - backing up and pulling forward. brakes failed when the trucks rpm fell below 800 rpm and the vacuum assist failed. the vehicle was difficult to stop and i am a large man. have copy of repair bill from dealer dated 10/03/18. dealer was familiar with the issues and had serviced other chevrolet vehicles with the same problem. contacted chevrolet div/gm. made a call, send and -mail and wrote a letter. no response to letter or e-mail asking for a refund. received a call in response to my call. chev rep stated they had no knowledge of the problem.?? told the caller than only need to check the internet to find many complaints. consumer reports that only 111 complaints have been received. i strongly suggest there are many more. i suspect the number of complaints will increase not that the "cat is out of the bag" so to speak. please insist on a recall i think it will save lives. no need to wait until someone dies.
I've noticed a big decrees in breaking performance in the past month doubling the distance it takes to completely stop and it's almost caused me to rear end a few people.
Brakes become extremely hard and have to push down with big feet to stop.
Brake pedal becomes very hard and brakes ineffective if the pedal is pushed and released at idle. brake do not start working properly again until the accelerator has been pressed. "service brake assist" message is displayed on the diagnostics screen. definitely a problem with the vacuum pump.
When trying to park the brake pedal seems to become very stiff and the vehicle doesn't want to stop. i have to use all my weight on the pedal to get my vehicle to stop. it seems to always happen a slow speeds. i have been able to duplicate the problem when parking in my drive way, a parking lot, and it happened during a 3 point turn.
At low speeds and or starting from a stop and reapplying the brakes the brake pedal gets extremely hard and will not hold the vehicle from rolling forward. you must press the brake pedal as hard as you can with both feet to try to keep the vehicle stopped. i have to put the vehicle in neutral at each stop. each occurrence has happened on a city street.
My brakes failed to work when i was pulling into my parking lot. it seems to happen intermittently and only at low speeds. the brakes worked again later in the day. i took the vehicle in to the dealership i purchased it from (river view chevrolet in mckeesport pa) and they said they did extensive test but could not recreate the issue and could not find a problem that would caused the brakes to not work.
Loss of brakes 2 times once on interstate 40, and once on a hill in town..brakes went to floor .finely stoped.
Tl* the contact owns a 2015 chevrolet silverado 1500. while the contact's spouse was driving 5 mph, the brake pedal was depressed, but failed to slow down the vehicle. the contact stated that the brake pedal felt very firm. the vehicle was driven to moran chevrolet (located at 4511 24th ave, fort gratiot twp, mi 48059, (812) 202-4062) where it was diagnosed that the vacuum pump, brake booster, brake lines, and brake master cylinder needed to be replaced. the vehicle was repaired. the manufacturer was notified of the failure. the approximate failure mileage was 63,324.
Very stiff brake pedal while trying to park at slow speeds. could not press the pedal hard enough to stop the vehicle while i was backing into my parking spot. this is very dangerous as there are pedestrians and other vehicles in the parking lot. i do not feel safe driving this vehicle. it also happened when i backed into my parking space when i returned home.
