On two separate occasions within a 1 week period, the brake pedal became impossible to depress with the vehicle in motion. A noise could be heard similar to that of an active ABS. The first time this occurred while pulling into a crowded parking lot. I had to use the emergency brake to prevent a collision with a parked vehicle. The second time this occurred, I was parking at a curb in the main area of my town and again had to utilize the emergency brake to avoid hitting a parked vehicle. Internet research leads me to believe this to be a common issue with multiple reports of the same experience.
2015 Chevrolet Silverado 1500 brakes complaints
Page 13 of 14: complaints 341 to 370 of 374, newest first, as owners wrote them.
The brakes will become very hard to press when they become hot. Driving at low speeds and in reverse, after the brakes are hot (highyway driving, then down to city traffic). Very dangerous if not aware of this issue.
Left side brake calliper support bolt fell out of top mount.(lost on hwy). Bottom bolt half way out. Calliper started scrubbing inner rem. Vibration and loud popping noise.
I was backing into a parking stall the the brakes failed again! Brake pedal was solid and would not depress to slow the truck to a stop. Only after extreme pedal pressure was there any braking action, but only slight. Because of this I hit the wall behind the truck. If someone was there, I would not have been able to stop. Gm/chevrolet have a service bulletin out on this issue. An internet search came back with 312,000 results. I've talked to my selling chevrolet dealer and they reluctant to deal with it. Does somebody need to die before something is done. This is the 4th or 5th time my brakes have failed.
Have not even had my chevy for a year and the brakes seized up causing the vehicle to not stop. Noticed there has been some issues having it towed to a chevy dealership to see the cause of the problem, looks as if gm is aware of the problem, so don't know why I was not notified of this issue, could of been a very serious accident as I travel on the freeway at high speeds.
While in a parking lot, there was an almost complete loss of brakes. The brake pedal would not depress. Only after pressing multiple times and very hard was there any braking action which slowed the truck. Gm has issued a service bulletin, pit5361 about this issue. This is a known issue.
Need to replace the vacuum pump and line because brakes are wicked soft. At slow speeds truck doesnt want to stop. For example in traffic or parking. When I went to the chevy dealer they told me that they've seen a handful of other vehicles with the same issue
Truck has 62k. Truck will not stop at low speeds. Could easily back into and or over something or someone very easily. More frequent when at low speeds and while backing up. I almost backed into a roll up door before slamming on the parking brake. Took truck into dealership and was told that the vacuum pump, vacuum belt and hose from vacuum pump to brake booster needed to be changed. This is not a warranty fix.
I was driving on the highway at 50 miles an hour during rush hour traffic, traffic began slowing down and as I went to push on the break, it was extremely hard. I could not push the break down at all, and my car would not slow down. I placed it in neutral and was pushing as hard as I could on the break with both feet. Finally, the truck began to slow down. I put me emergency lights on and crosses over 5 lanes of traffic, as I was in the carpool lane, to get off the highway. It was a very dangerous and scary situation.
Tl* the contact owns a 2015 chevrolet silverado 1500. While driving 15 MPH, the vehicle began to lose vacuum pressure when the brake pedal was depressed. The contact had to apply excessive force to the brake pedal to bring the vehicle to a complete stop. The contact stated that the brakes engaged once the vehicle reached 1,000 rpms. There were no warning indicators illuminated. The failure recurred twice. The vehicle was taken to performance chevrolet (4811 madison ave, sacramento, ca 95841) where it was diagnosed that the vacuum pump needed to be replaced. The vehicle was repaired. The manufacturer was contacted and stated that the vehicle was out of warranty. The approximate failure mileage was 46,000.
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.
Received an alert around 63,500 miles "alert: service break assist." dealership service advisor notified me that problem was "brake master cylinder leaking into vacuum boster. Both need to be replaced." cost $1172.61. Break basically wouldn't work properly when pressed. This should not happen so early. I've only had truck for two years. Chevrolet needs to fix this. This could have caused an injury to myself or my family.
Power brakes fail at low speed requiring more pressure to come to a complete stop. Occurred multiple times I while parking or idle speeds.
When pumping my brakes for traffic, backing out of driveway or driving in general etc., brakes will fail and my truck keeps rolling. Not safe what so ever as I am stomping on the brakes as hard as I can and the truck will not stop. Please fix this issue by contacting chevrolet for a recall. This has happened to multiple friends and family with this truck model and year. It is a problem and gm needs to know about it before somebody gets killed for brake failure. Truck is not even past 40,000 miles!!!
Brake pedal will go hard on sporatic occassions at low speeds
The truck experienced a hard brake pedal at low RPM, stop light, parking lot, etc. When brake is depressed the pedal is hard to press and the braking ability is reduced and the truck will continue to roll. Chevrolet is aware of the problem and issued a bulletin in february 2015, my 2015 was purchased in september 2015. When I complained of the issue at dealer, I was told I am out of warranty and would have to pay a portion of the repair on a known defect.
Brake pedal gets very hard when driving at slow speeds and in reverse. Makes a ticking sound like the anti lock brakes are kicking in but no dash lights illuminate. Almost rear ended a vehicle travelling 25mph but was able to pull in a parking lot to avoid collision. Truck has 79xxx miles
Hard braking at low speeds. Brake pedal becomes hard and truck hard to stop. Possible brake booster defect. Attempting to park in parking stall, had to put truck in n to stop. Commuting to work in traffic at low speed and pedal becomes hard, truck hard to stop.
When taking a long, rather sharp turn on the highway, the vehicle was resisting against the turn making it difficult to maneuver the vehicle. At the same time, the brakes began to initiate when the pedal was stepped, but immediately became very hard and could barely slow or stop the vehicle. Almost hit the vehicle in front due to the delay and difficulty in braking.
Brake system was not working properly when I drove at low speed. I ignored it once in july 2017. But I had same issue again on aug. 31 and sep 1 at the parking lot. I almost hit the car in front of me. I fixed my issue at chevy dealer, and they replaced vacuum pump. (~42000 miles on the truck)
At low speed with stop and go traffic loss of brake assist/boost. First application of the brakes was normal. After release and reapplication, brake boost was lost, pedal became very hard and vehicle failed to stop.
About 41000 miles on my truck. I had braking problem when driving at low speed at parking lot. I almost hit the car because I was not able to stop due to the braking issue. I felt loosing pressure while braking. I had this issue 3 times. On july 16, I noticed the issue then it did not happened again. But it came back again on august 31 and september 1. I took my truck to dealer and they replaced vacuum pump. I found that many people had same issue but no recall. I had to spent about $500 for new vacuum pump.
The brake assist warning light came on while driving and the could not brake properly the brake pedal was really hard to brake. A;most had a wreck cause I could brake properly on time
Power brakes stop working at low speeds. It seems the vacuum pump is failing. Sometimes at low speeds the brake pedal goes hard and requires alot of extra effort to stop. I almost ran into the rear of a car in a drive-thru.
At a low speed coming into my carport the brakes had a hard pedal and would not stop. This has happened on two occasions. 5-27-2017 and again while backing up to my lawn mower tailor on 5-29-2017 . Not sure what the problem is but you could not press pedal down at all. ?????
I went to back out my driveway at low speeds and the brakes did not apply. I put it in drive and applied the brakes and they failed again. I applied the gas and went on my way the brakes seemed to work fine. But from idle to slow speeds (1-10 MPH) the brakes fail and I have to press the brake as hard as I can or it will continue to roll. Have dodged several cars at red lights.
Front brakes on left side stick and wear unevenly and rapidly. I have had front brakes replaced twice with 80% pad life on right side by midas. Midas stated that there is a service advisory to replace the left side piston/caliper and a new hose which is larger allowing the brakes to release properly.
While driving my family, I lost over 90% of my stopping power while exiting the highway on an off ramp. Luckily it happened when I had already slowed down off the ramp to get off the highway (and not just moments before while on the highway). After extreme caution and smart use of down-shifting and the emergency brake, I was able to slowly navigate into a parking lot that was really close to where the incident first happened. After having the truck towed to my dealer, the service department said it was a vacuum pump failure and replaced it (note that they offered no other explanation other than what failed and that it was fixed). The truck seems to be okay for now, but I am very concerned about my (and my family's) safety and overall reliability of this truck. Who's to say it won't happen again while I'm in a more high-speed situation?
Vehicle in motion on city street, ABS light came on sporadically. While ABS light was on, braking system would engage. Two days after incident, ABS shows constant, all the time, ABS brakes randomly engage.
Front brakes completely worn at 12,000 miles. Dealer replaced rotors and pads free of charge. Vehicle now has 20,000 miles on it, and front pads are worn prematurely again.
