I noticed over the past couple of days, when vehicle is moving at very low speeds less than 10mph, the brake pedal is hard to push down and vehicle keeps rolling before coming to a complete stop. This can be replicated every time even when going in reverse. At speeds above 10mph, the braking system works just fine. This has caused a few near misses where I almost backed into another vehicle while parking in reverse in a lot; almost ran into my garage door; and almost crashed into another vehicle in front of me at the light. If you go from park to drive and just lift your foot off the brake pedal without applying gas and vehicle starts rolling, then you apply the brakes, it will keep rolling a few feet before coming to a complete stop and as mentioned previously the brake pedal is hard to push down and only goes down about a couple inches. I am scheduled to take my vehicle in to service this issue at the dealer.

Brakes have fluttered intermittently for the past few months at low speeds, feels like ABS pulsing. In the past week to 10 days, brake pedal feels "dead" when I apply brakes at low speed, has gone to floor with no response to braking input. Yesterday, when pulling in driveway towards garage, maybe 3 mph, applied brakes with no response. Shifted quickly into neutral and applied parking brake, stopping inches away from garage door. Truck was in for brake issue recall and was recalibrated on November 16, 2019. Apparently it needs to be recalibrated or have further repair.

When pushing down on the break pedal it's not slowing down and stopping the truck it's happened about

- Lake Elsinore, CA, USA

I noticed a ticking noise from my engine compartment while stationary, and began experiencing a vibrating brake pedal/noise when braking at low speed (in driveway or parking lot). I had a 'service- brake assist' message show on my instrument cluster. On 11.3.2020, I early struck another vehicle while pulling into a parking spot due to a dramatic increase in effort to press the brake pedal. These symptoms continue at the majority of my low speed brakes, I haven't noticed it while on city streets or highways.

Got alert from onstar about anti lock braking system.

- Calhoun, GA, USA

While parking the truck I loss all brake pressure. The pedal went to the floor and I had to stand on the brakes to get the truck stopped. Once stopped and parked I repeatedly pumped the pedal with no changes. I had the truck towed to a mechanic who found no issues with the fluid or system in general. He drove the vehicle with no issues for 10 minutes. He checked the pads and calipers for any issues with none being found. After putting the wheels back on the truck it exhibited a recurrence of loss of brake pressure.

Break failure at low speeds due to lack of vacuum from a defective vacuum pump

- Sacramento, CA, USA

Vehicle was recalled for increased brake pressure at low RPM. Recall service performed at dealer. Vehicle still has increased brake effort issue after service was completed.

My truck had the electronic brake control module reprogramming with sps as per recall N192268490 performed. The reprogramming worked fine for a few months. In March 2020, I noticed that at low speeds and mainly when backing, the brakes began to lose pressure and what sounded like and felt like the antilock brake system was engaging, and very hard pressure was needed to stop the truck with longer than expected braking occurring. The problem has definitely worsened and occurs nearly every time braking at low speeds in reverse with any type of incline. While backing my boat into a driveway, this issue occurred and nearly sent the boat into the garage door. I had to apply as much pressure as I possibly could to the brakes to stop the truck and boat before hitting the garage door. The issue has occurred repeatedly as I have backed up on an incline, with or without a trailer or boat attached to my truck.

My truck had the electronic brake control module reprogramming with sps as per recall N192268490 performed on November 11, 2019. The reprogramming worked fine for a few months. In March 2020, I noticed that at low speeds and mainly when backing, the brakes began to lose pressure and what sounded like and felt like the antilock brake system was engaging, and very hard pressure was needed to stop the truck with longer than expected braking occurring. As a few months more past, I did not recognize the problem much as we have quarantined during the covid-19 crisis and have not driven much. However, since late may, the problem has definitely worsened and occurs nearly every time braking at low speeds both moving forward and reverse. I have now seen the warning to service the brake assist message appear on my dash. On May 28th, 2020, while backing our boat into storage, this issue occurred and nearly sent the boat into the storage entry side wall as there is a slight hill just in front of our storage. I had to apply as much pressure as I possibly could to the brakes to stop the truck and boat before hitting the entry side wall. The issue occurred repeatedly as I had to maneuver the boat back and forth much differently to account for the braking issue. I notified my local Chevrolet service department and was told a new vacuum brake pump would need to be installed and would be at Chevrolet's expense.

Vehicle loses braking ability when in a slow-speed situation, such as when parking, going through a drive-through restaurant, or when in stop-and-go traffic. Brake pedal will go to the floor when the situation occurs. A noise may occur that appears to be the anti-lock braking system trying to engage. Pumping the brakes seems to restore functionality for a short period of time. The issue does not occur when the vehicle is traveling at street and highway speeds.

My truck began with a notification that says "service stabilitrak", over the course of 48 hours it went from on hard bumps and just the notification, to now constantly turning on. There was a recall for this issue with the ABS, but I have to pay the dealer out of pocket. They are currently doing the diagnosis on it to see what the issue is. If the issue matches the same ABS issue as the recalls for 2014-2018 models on the Silverado, would there be a way to fight the charges? the warning notification and icon would light up when either stationary or moving at any speed. 48 hours ago it would only do it when turning at almost full rotation, or driving over some cracks on the road. Now it just does it randomly and very often to where the brakes would shake when applied. Power also goes down a bit, and the wheel would jerk. Pretty much exactly as how all the prior complaints about it before the recall when it reached youtube. It makes driving very dangerous as I can be turning, then the wheel would spring back into a different position. Before this notification, when I apply the brake it would be very smooth. Now because the truck thinks there's some kind of ABS issue, when I brake, it would shake the brake response (like old cars before ABS) and also make the vehicle very unsteady. I cannot brake on a straight line as it would sway the vehicle.

Loss of brakes when in a slow mph situation such as drive-thru or parking lot situation. Requires significant pedal pressure to stop vehicle. Almost resulted in collision with vehicle in front of my truck, but was able to steer away before impact and stop safely. Many report of vacuum pump issue. Service brake assist message came up afterwards.

Backing down boat ramp with boat I lose the brakes and rolls backwards brake pedal pulse like ABS trying to work. This has happen about 6 times now only when backing down ramp with boat otherwise can't recreate.

- Huron, TN, USA

Brakes have no power assist at slow speeds. Started when parking slowly in reverse, but also can do it moving forward. Brakes fail and require very hard press of brake pedal to engage at all! seems like vacuum pump is going out. Looks like a common complaint/problem that Chevy should recall and has not. It is a major safety issue!

- Boise, ID, USA

I had GM recall N192268490 (NHTSA campaign 19V645) completed several months ago. Today as I was backing up at low speed I almost crashed into my garage due to increased braking effort required to stop the vehicle.

- Baxley, GA, USA

While driving on a highway; approximately 55 mph, on a rainy day, I applied the brakes and they wouldn't grab. They were hard so I pumped the brakes twice again and they grabbed slowly but the pedal was very hard. That same day; while driving 5 mph, I applied the brakes and there was a trembling and a noise. This major and dangerous issue is intermit and needs to be addressed immediately. I explained this to the dealership and they have yet to follow-up to fix this problem. They said it was probably the engine-mounted mechanical vacuum pump.
