Braking issue causing rear-end collision at low speed on highway in rush hour traffic. Increased stopping distance, increased brake pedal effort.

- Weymouth, MA, USA

Brakes not effective when stopping at low speeds. Dealership repaired, stated it was a known problem but not a recall and a vacuum assist issue. I was involved in a traffic collision at low speed on the interstate. ABS did not engage and I was unable to stop colliding with the vehicle in front of me.

Loss of braking in stop and go traffic. Vehicle brakes are extremely difficult to press in slow moving stop and go traffic. The ABS seems to kick in but the vehicle continues to roll forward. Speed would be around 10 mph. Braking is ok at normal highway speeds but losing ablility to brake at low speed. Near miss on rear ending several vehicles.

While parking in my work lot at low speed, my pedal became very stiff and vehicle was very hard to stop. This problem repeated the same day in my driveway at home. While researching online I learned about the failures of brake vacuum pump. Purchased and changed mine myself.

One morning when I got to work I was backing in my parking space, when my brakes got hard to the point that I could not press them. It was to the point that my truck would not stop unless I used both feet with heavy pressure. If I was driving I would have never stopped that truck. I was just outside my warranty with 39000 miles on the truck. I had it towed to the dealership and they told me that I had to replace my vacuum pump.

My brakes failed to stop my vehicle at slow speeds and while I was at a decline and almost caused me to rear end another vehicle. The brake pedal got extremely hard and would not allow me to press down on it.

I pulled into crowded parking lot in the rain & couldn't stop my truck. I used both feet to press brake as hard as I could & got truck stopped. Brake pedal was very hard to press and had to pump brake about 3 times to get stopped. Truck was fine for next 3 days & then it happened on interstate at 75 mph. I was pulling a trailer & the only way I got truck stopped was to use manually press trailer brake mechanism inside truck. It really scaredme as I had my kids in truck with me and valuable livestock in trailer. At dealership now getting it checked out. I'm over 36,000 warranty but under 60,000.

I was pulling into wal-mart in white settlement, went to brake to slow down and it felt like the pressure was completely gone causing me to brake harder to stop.

This morning at low speed stop and go traffic and again when low speed parking the black pedal became hard to push and car would not stop properly. Happened both directions while parking. Will take to the dealer this afternoon. Seems to brake fine at higher speeds and slowing from higher speeds. Scary

When pulling into a parking space the brakes became really hard to push and took longer for brakes to apply to stop the vehicle. Took the truck to mk smith Chevrolet in chino, ca and they diagnosed the issue as a faulty vacuum brake pump and replaced it since it was under manufacturer warranty.

The contact owns a 2017 Chevrolet Silverado 1500. The contact stated that the service brake warning indicator illuminated and the trailer brakes failed to work. The vehicle was taken to star Chevrolet (5200 us-30 C, greensburg, pa 15601) where the failure code was erased and the brakes returned to normal; however, the failure recurred approximately five times. The vehicle was not repaired. The manufacturer was notified of the failures. The approximate failure mileage was 18,707.

For no apparent reason the stabilitrack service indicator will activate in a variety of settings, ie low speed on a road, high speed on an interstate, parked in a parking, etc. I have taken the vehicle to our local GMC dealer and they are unable to replicate the issue or locate a code that is occurring when this warning indicator activates; this occurred last week and as recently as this morning while I was driving to work

Brakes failed when driving slowly in both forward and reverse. This occurred following a period of extensive highway driving. Brake pedal was extremely hard to push and resulted in no braking of vehicle. No trailer towing was involved.

When we first bought the vehicle we received the error message: Antilock brakes & stabilitrak problems & wheel vibrated terribly. Took it in, they said it was the computer and fixed it. This morning error re: Anti lock brake problem and no brake fluid (put in a whole can) and error traction off (but we did not turn it off) this is a new vehicle and we could get killed or kill another if there is a brake failure. This should be a recall and GM should buy back the vehicle from us. Thank you for any help you can give us.

Hard brake pedal. Loss of all power assistance. 2017 Chevy 1500 34K first did it highway speed then I got it to repeat at slow speed multiple times. It would lose all brakes after two or three light applications of the brakes. Very unsafe I almost rear ended some one I'm fairly strong it took both feet pushing as hard as I could to slow vehicle and whip around car to avoid if my wife or son would have been driving it very different out come than a trip to Chevy
