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.
2015 Chevrolet Silverado 1500 brakes complaints
Page 11 of 14: complaints 281 to 310 of 374, newest first, as owners wrote them.
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.
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.
Brakes become extremely hard and have to push down with big feet to stop.
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
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.
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.
Brakes failed exactly as described in nov 26 consumer report article and exactly as currently being investigated by the federal safety agency. 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.
While driving on the highway approx 40 MPH, traffic in front of me stopped suddenly and I applied as much force on the brake pedal as I was physically able to. The truck began slowing but not nearly fast enough and I collided with the vehicle in front of me. The brake performance seems to have declined over time and I was unable to stop in time to avoid the accident. There appeared to be plenty of room to stop but the truck did not perform as expected. I am reporting because I read an article regarding a probe into issues with the brakes on the year truck that I own. At the time I did not think too much about it but now I believe that this braking issue may have directly resulted in the collision.
I purchased my 2015 silverado pre-owned with 2,000 miles in october 2016. In may of 2018 I was traveling through multiple states. I was stuck in slow traffic for multiple hours due to an accident on the highway. It was then that I first experienced an issue with my brakes. When moving at a very slow pace, the brakes seemed to lose the power assist. I took the truck in for it's oil service at castroville chevrolet on 6/22/2018. I mentioned this issue to the service writer who was not aware of any issues with the silverado brakes. At the time it was cost prohibitive for me to have it investigated and could not lose the vehicle for an extended time. It has happened multiple times since then, again only at very low speeds, such as parking. I have an appointment on 11/28/2018 with castroville chevrolet to have it looked at. All of these incidents happened while in motion. I believed it to be a vacuum issue as it only happened at low speeds.
Loss of brakes 2 times once on interstate 40, and once on a hill in town..brakes went to floor .finely stoped.
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.
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!!!
Brake pedal gets very hard while in traffic especially while towing a trailer. Dealer initially couldn't find an issue but eventually replaced the brake vacuum pump, it got better but still intermittently does it. When it happens you have to stand on the pedal with everything I have to get the truck to stop.
Noticed brakes seemed to stop working properly at low RPM.happened while backing out of driveway. Also while sitting in traffic at redlight.
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 applied the brakes firmly for a car stopping short unexpectedly on the highway. I released the brake for a second or two to allow room for the car behind me to stop in time. When I reapplied the brake the second time, there was little to no braking action. The pedal did not more and did not travel all the way to the floor. There was no power assist. I was able to recreate the problem later at low speed when there was no traffic. I brought the truck to the dealer who could find nothing wrong but replaced the brake vacuum pump. The condition has not re-occurred since the repair was made in may. I have included a copy of the service invoice. I am reporting this because I see on the news you are investigating brake issues.
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.
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).
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.
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.
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.
Brake pedal becomes unresponsive and soft at times, and other times feels like the brakes are not releasing all the way making it pull left/right randomly and very hard to control. Occasionally the ABS activates while not moving/parked just by by holding brake pedal. Also found oil of some kind in brake fluid during routine flush. Vacuum pump makes quite a bit of noise.
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.
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.
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.
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.
Loss of braking at idle speed brought t ok desler ghey replaced multiple components extended warranty covered all but $100
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.
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.
