I was driving along the highway exit ramp when I went to brake; the brake pedal was stiff, and the vehicle wouldn't stop. I had to put my full body weight into it, and that’s when the car came to an abrupt halt. I nearly crashed into the car in front of me. I took it to the Bomnin Chevrolet dealership, and the service advisor informed me that the vehicle had logged a fault code or something similar. The vehicle is currently at the dealership. Prior to the incident, there were no on-screen indicators, warnings, or warning lights. It was only after the brake failure that a message appeared on the screen—along with the wrench symbol—reading "Brake Assist Service."

The brake booster vacuum pump failed catastrophically while driving, resulting in a sudden, dangerous loss of power braking assist and a rock-hard brake pedal. Upon inspection by a mechanic, the pump's internal failure violently sheared and destroyed the engine's exhaust camshaft, requiring a complete camshaft tear-down and replacement. This is a severe mechanical defect causing both immediate highway safety hazards and internal engine destruction.

Brake assist suddenly went out. No warning lights what so ever. Happened thankfully when pulling into my driveway at slow speed. Had to stand on the brake pedal to get stopped. If this would have occurred at interstate speeds. It would have been bad.

While driving on the freeway, I experienced a sudden issue with the vehicle’s braking system. The brake pedal became extremely stiff and difficult to press, and the brake assist stopped functioning. I was still able to apply the brakes, but it required significantly more force than normal to slow and stop the vehicle. Prior to this incident, I had also noticed an issue where the engine did not shut off normally after removing the key. The engine continued running briefly before shutting off with a noticeable rumble/shudder. I do not know whether the two issues are related, but I am including this information because it occurred before the brake-assist failure and may be relevant to diagnosing the vehicle.

Component that failed: brakes. I was pulling into a parking spot at low speed and the brake pedal was suddenly extremely difficult to depress, almost impossible. It felt as if a brick were under the pedal but there was no obstruction. I was able to stop only because I was already going so slow. Safety of myself and others was at risk because I was almost unable to stop the vehicle. If I had been going any faster I don't believe I would have been able to without crashing into an obstacle. Vehicle is currently at a service shop but issue has not been verified or repaired as of today. When restarting the vehicle, the engine stuttered and started making odd sounds, and wouldn't idle properly. There were no warning lamps, messages, or other symptoms at all prior to failure. When I entered the parking lot it was working normally and when I turned to enter a parking spot the brakes suddenly just failed.

I was driving down a street, stopped for an accident that the police where directing traffic for, went passed the 2 officers, put my indicator light on to turn into Dunkin Donuts and stepped on the brakes and they failed. I was lucky there was an incline and no one behind me, I was able to drive up the incline and use my emergency brakes to slow and stop the car before going over the top and down the other side. I called the tow truck and was towed to my auto shop where is was discovered, my car suffered a catastrophic brake failure. Thank goodness I was not on my usual route with my special needs son and wasn't going to fast. This is a known failure of the brake vacuum booster pump and this damaged my camshaft and timing chain and cost a fortune on a car barely out of warranty. This would have been a death sentence for me and my son if I had been on a highway, as well as other people on the highway, if I wasn't able to stop for construction, someone cutting in front of me or any other incident on the road. This is NOT acceptable and these vehicles should be recalled!!!!! I am not the only one that has been through this since 2014 TERRIBLE-recall this part before someone dies, like they did in VA with the bus. I also had to rent a car during the repairs so I could get my son to his activities. This whole incident that should have been covered under a recall has caused my son to have PTSD with this vehicle.

The contact owns a 2022 Chevrolet Colorado. The contact stated that while an employee was driving approximately 30 MPH up to a red traffic light, the brake pedal failed to slow the vehicle while depressed. The driver used an excessive amount of strength to depress the brake pedal for the vehicle to come to a stop. The contact was unable to confirm any warning lights had been illuminated. The vehicle was taken to the dealer where it was diagnosed that the vacuum pump had failed and needed to be replaced. The failure caused the engine to fail. The contact was informed that the engine needed to be replaced. The vehicle was not repaired due to the parts for the engine being on backorder. The manufacturer was made aware of the failure. The failure mileage was 69,000.

I went to a Chevy Dealership, Ed Morse, Sunrise Fla. for an oil change and they told me I need all 4 new brake pads at estimated mileage of 27000 miles. I was shocked because I never needed brake pads that soon. I called Chevrolet corporate to see if there was something defective that they could tell me about. Chevrolet Customer Service filed a case and told me to take to a dealership in my home town, Tallahassee Florida. I scheduled an appointment with Dale Earnhardt Chevrolet. When I went there they told me it would be $199.00 on my credit card. I told them it under warranty and they told me that was their policy. I called Chevy CS and they said that there was nothing they could do. I did tell them this is a safety issue but they didn't care. The brakes are completing worn so there must be an issue with the system for the vehicle to go through brakes so soon. It is driven mostly highway and I am [XXX].

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
