On 01/16/2026, Quirk Chevrolet completed product safety recall N242482680 for the Brake Pressure Switch Connector Fire on my vehicle. Shortly after, my vehicle would come to an abrupt stop on its own while driving. This happened twice on my way home and then the third time at home at which point, it would no longer move forward or backward. The vehicle needed to be towed to the dealership that did the recall. After researching online, I discovered this is a known issue after the recall because the recall component is faulty. One source reports the cause is an improperly manufactured jumper harness which is missing protective tape or a faulty internal C-clip in the cylinder. Another source states the post-service emergency brake issues often stem from a software update meant to enhance safety or an incomplete repair of the brake pressure switch wiring harness. The update automatically engages the parking brake. I absolutely know that the catastrophic failure of my vehicle's braking system was a direct result of the recall work; however, the dealership made me pay for the repairs out of pocket until such time as GM or Chevy makes an "official" recall on the faulty recall. My safety and the safety of others was put at risk by way of my vehicle stopping abruptly on its own. The problem has been reproduced by many sources online - just do an online search "2021 Chevy 5500 emergency brake issue after brake recall completed" and see all the results that come up corroborating my personal experience. Quirks Chevrolet in Manchester, NH inspected the vehicle. No warning lamps or messages appeared on the dash. Please contact me if you want any additional information or copies of receipts, etc. My vehicle is available for inspection upon request.

Took truck to dealer with concern of higher than normal braking force needed. Couldn’t verify concern. Looked today under the steering column and the brake booster is leaking fluid inside the cabin of the truck when the brake pedal goes through the firewall. There was Almost no brake fluid inside the reservoir causing the brakes to fail with no warning. Looked at similar trucks and all have brake fluid leaking from the same location. With as little as 10,000 miles. Mine has 22,000 miles and it’s failed requiring complet replacement of the brake booster. Taking to the dealership to replace the complete brake booster assembly when part is available. This is a 21 Chevy 2500 truck that pulls up to 18,000 pounds. higher than normal braking application needed, can be deadly or lead to complete brake failure whether loaded towing a trailer at a weigh of 25,000lbs or even the 7,000 pounds empty the truck weighs would reasonably result in the loss of someone’s life. Only thing that drew me to this concern was a harder application of the brake pedal and noticing brake fluid under the dashboard. Would gladly allow anyone to inspect my truck.

The brakes have squealed since the day we purchased it new. The noise is usually at low speed, under 10 MPH. The dealer has told me that they could replace the pads but I would have to cover the cost.

Non stopbbreak noise. No matter what you do, what is or isn't added, how clean they are, they constantly squeak and loud! Dealers won't help. Tell you to get on the brakes hard. That helps for a few minutes! Over 50k fix the brakes!!!
