Brake assist issues occured while in the mountains. It was difficult to brake almost causing an accident. It appears to be a bad brake vacuum pump.

We were on vacation driving to Florida by the time we arrived 1500 miles later I had no brakes. This happened on a Friday. We called our mechanic in Oklahoma to explain it to him. He had us check a few things to see if it was a number of thing. He said it was the brakes vacuum pump. He had one in the shop for the same thing. You can't get in to a Chevrolet dealer to have it fixed in the time that we had. My husband did fix it but was extremely scared to drive in South Florida with limited to no brakes. My truck only had under 80 thousand miles on it. We live in a rural area so it's not like constant braking.

We were heading on vacation to Florida on the evening of [XXX].While driving [XXX] towards Athens, Alabama we heard a squealing noise from our engine that lasted a minute then it stopped. We got off at the closest exit and realized that we had -??No Brakes -??. I prayed for our safety. Our truck ran through two stoplights that were red at the time. I downshifted the vehicle and stood on the brakes (hard pedal) and jumped over two concrete curbs before it finally came to a stop. We had it towed to Champion Chevrolet dealership in Athens Alabama. They diagnosed the problem as a brake vacuum pump that locked up and broke the belt too leaving us with no brakes at all. Champion Chevrolet worked us in and replaced the vacuum pump and belt.And got us back on the road for our vacation. We had to pay for a tow truck $100. An overnight stay at a hotel $150. I-??m concerned about the tires, rims, alignment and suspension being damaged by jumping over the concrete curbs. I-??m requesting a free inspection at a local Chevrolet dealership to thoroughly inspect and repair any damaged parts and a realignment. I also am out of pocket $250 for the tow and hotel room. I feel I-??m being fair to ask for reimbursement and repairs. The dealership didn-??t charge me for the repairs of the vacuum pump and drive belt as it was covered by a special recall (N182202780). Please direct me for escalation of reimbursement, complimentary inspection and repair of my 2017 Silverado suspension or damages involved in this incident.

excessive squealing noise coming from rear brakes from both sides of truck. I am original owner, and truck has less then 15,571 miles on it. Drove it to Chevrolet dealer in Kingsland Ga to evaluate. Before I arrived, about a 15-minute drive the Brake towing warning light came on. I was told by the dealership that both Brake Calipers had to be replaced as well as the brake pads that were damaged due to Brake Calipers locking up. The brake Rotors were fine and needed nothing. Repairs cost me around $1000 dollars. I think this is an unusual event due to the low milage, truck has always been garaged and dealership maintain. It's in brand new condition. Pulling a camper or trailer or even normal driving without towing could potentially cause an incident, fire or wreck. My truck is gasoline not diesel not included in the current safety bulletin. Truck was kept for 2 days for repairs.

This is a complaint in regards to the trailer breaking system in my certified pre-owned 2017 Chevy Silverado that I purchased in April of this year, 2024. I purchased this truck in particular for its high ratings in safety and towing capabilities. (April- May 2024) While towing a 22ft trailer from Virginia to Washington state, there were several moments where the -??service trailer braking system-?? alert would appear on the dash. Driving on the interstate for days on end is twice as stressful when you have to wonder if your trailer brakes are reliable. If the trailer brakes were to suddenly stop working it would be dangerous for me and my passengers, as well as those around me on the road. (Sept- Oct 2024) We aren-??t towing a trailer anymore, but the -??service trailer braking system-?? light has been going off every couple minutes.

Waiting on dealers evaluation and inspection.

Lost brakes 11/20/23 and GM replaced vacuum pump per policy n182202780. Vehicle had 143522 miles on it. Lost brakes again on [XXX] and vehicle needed another vacuum pump. This is just six months after first repair and vehicle now has 152987 miles. GM denied repair because truck had gone past 150000 miles.

Brakes failed. The brake assist pump disintegrated, sending metal fragments into the Motor's oil circulation system. I was able to stop the truck using both feet and applying extreme force to the pedal. The dealer identified the problem. The "Brake Assist" warning light came on during the episode.

We Bought a Chevy Silverado 1500 truck used in Nov 2021for purpose of towing RV trailer. In having axel bearings packed on trailer March [XXX], 2024, the RV mechanic noticed no wear or brake dust. He checked and determined RV brakes had never engaged and found no power to the RV brakes in the plug in port on back of truck. Took to dealer, Chesrown in Delaware Ohio, on [XXX], 2024. After having truck all day they said issue was brake modulator which they reprogrammed. We hooked up RV trailer and brakes still do not work. Hand brake controller on dash will engage the trailer brakes, but not the foot brake. In researching online, there is a great deal of discussion about GM knowing about and not addressing the issue. There-??s a known defect in a wiring harness between two of the body control modules. This part is known for broken wires and for connective issues. We reached out to GM Customer service at 800-222-1020, who took our information and said they would contact the dealer. We took truck in today and explained again what the issue was and what we had learned from our research. There are currently several recalls on 2022 and 2023 Silverados for the same trailer brake issues. GM needs to take responsibility for this critical service issue!! We CAN NOT tow a RV trailer WITHOUT BRAKES! When we asked the service manager why the tow package was not part of the inspection process when they took the vehicle in and placed it for sale as a used vehicle, he said they don-??t do that. Seems to us, that when a dealer sells a vehicle, all parts should be in working order. Especially with a factory installed tow package. PLEASE research and contact GM and have them issue a RECALL on ALL of their vehicles with factory tow packages to ensure the safety of all of those driving them! You will find numerous forums online where the biggest complaint is the trailer brake system not working and people very frustrated with the lack of response from not only GM but the dealers.

In reverse my brakes dont work, its like they are grinding, ive changed the rear brakes hoping to fix the issue, i have no codes. It has almost made me wreck due to failure to stop with my kids in the truck, also the afm system is defective in order to keep my engine as safe as possible i had to put a afm deactivate plug into the obd port. Ive tried to figure out the brakes but no one can explain. Spending 34 thousand dollars i expect to have my vehicle safe for my children. I have been strictly chevy my whole life but this is unacceptable. Where we live in alaska id expect the vehicle to be in order and it does it mainly at steep hills and it hasnt done it when ive had people look at it.

I had our pick up inspected today and the mechanic asked about our brakes being hard to push. I explained It has been that way for some time. He informed me that GM had a recall for this safety issue but as of this moment it doesn-??t cover our specific pick up. The recall reference number is: 19V645000. GMS number for the recall is N192268490. I called and filed a complaint with Chevy complaint #[XXX]. Any assistance with this safety issue would be greatly appreciated.

Vehicle only has 86,000 miles. Brake vacuum pump issue has failed and almost caused an accident or even death. I took my tuck at an easy trail in Big Sur CA. Brakes wasn-??t working properly. I feared it would completely fail and cause us to fall off the cliff. Fortunately we got off that trail, but as we continued to drive on highway 1 the brakes would not stop the vehicle as it should. The truck would still move forward or even in reverse with the brakes pressed down. Brake pedal was hard to press and would get stuck. There were no warning lamps on to alert me. This issue has been going on for about a year and has finally given out. The vehicle has been inspected and brake vacuum pump replaced by Smith Chevrolet in Turlock CA. I was told by the service person that Chevy has a 150,000 mile warranty on the brake vacuum pump part only so mine was covered. After inspection I was told that the brake vacuum pump had no fluids at all. Vacuum pump is defective.

At low speed my brake pedal goes all the way to the floor like I am losing my braking power completely. I found a recall on this issue but my truck doesnt seem to be included in this. How can I get my truck repaired before I kill someone.

1: BRAKES CONCERNS: I feel unsafe driving my truck. Brake pedals gets stuck, seems like a brake vacuum pump issue. Vehicle keeps slowly rolling forward or backwards even when brakes are applied. Even worse when on an inclined road, the truck will not brake properly as it should. It is very dangerous to my safety and others. It comes and goes, but it seems to be getting worse now. I have made an appointment to Chevy so that they can inspect it. But I am sure they wont help me since my truck is slightly over the manufacturers warranty. As always I know they will try to sell me an extended warranty. I fear this issue will get me in an accident. I have also looked online and have read a few articles about 2017 Chevy Silverado owners who are having the same issue.
