2017 Chevrolet Tahoe Brakes Problems

The contact owns a 2017 Chevrolet Tahoe. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic); however, the failure occurred after the recall repair. The contact stated that while driving at an undisclosed speed, the brake pedal was firm while depressed, and the vehicle failed to stop immediately. The contact, who is an independent mechanic, diagnosed the vehicle and determined that the vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 84,500.

There was a recall in 2019 (NHTSA Recall No. 19V645000) on certain GM vehicles for vacuum pump failure, which could affect braking and engine performance. The fix usually involved reprogramming the ECM to improve how the brake assist system operates - not necessarily replacing the vacuum pump unless it had already failed. My local dealership did the reprogramming but in 2025 the vacuum pump totally failed and left my vehicle stranded on the interstate. I had to have towed to a mechanic shop and the inside of the pump had broken into 3 pieces. So I had to have the vacuum pump replaced. During this time my car did not have brakes and put me and surrounding vehicles in a very dangerous situation. The mechanic gave me the broken part to show the dealership. The dealership said there isn’t anything they can do for assistance as I am out of warranty. There was a message that came up that said to service the braking system right before they stopped working.

It has happened several times when going slow the breaks get really hard to stop the vehicle. Otherwise breaks are new work well. One time I hit my garage as I tried to move it slightly forward. Another time I was slowly moving forward & tried to stop at a driveway as person was walking by. I pressed breaks down as far as the could go.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that occasionally while driving at various speeds, the vehicle failed to accelerate as intended while the accelerator pedal was depressed, and the RPM was elevated. In addition, the contact stated that the vehicle would brake independently while the accelerator pedal was depressed. The check engine and Electronic Stability Control warning lights would occasionally illuminate. The contact stated that restarting the vehicle was a temporary repair; however, the failure persisted. The contact stated that the windshield wipers activated independently, and all four doors locked independently. The vehicle was taken to a local dealer where it was diagnosed with a fuel injector #6 failure; however, the part was replaced approximately one month prior to the failure reoccurring. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control (ESC); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 95,000.

The contact owns a 2017 Chevrolet Tahoe. The contact stated that while driving at 75 MPH, several unknown warning lights flashed on the instrument panel, and the vehicle briefly shut off, then restarted while still in motion. Later, while driving at 45 MPH and attempting to complete a turn, the vehicle inadvertently lost motive power. The contact was unable to pull to the shoulder of the roadway, but the vehicle was able to restart. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The stability control warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with the alternator and transmission. The vehicle was repaired, but the failure reoccurred. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was unknown.

2017 Chevrolet Tahoe Brake Booster Vacuum Pump failed and had to be replaced. Booster sensor as well at cost of $1,493.22. Our vehicle almost hit another car in line for pre-school with children around and almost hit our garage doors due to this issue. Full recall in Canada but not USA? Why? "The amount of vacuum created by the vacuum pump may decrease over time. As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash"

The brakes become very hard to engage while at a low speed, consistently in traffic and the car rider line at school. It has caused me to almost hit cars in front of me and people walking between cars. To me, it feels like the brakes are sticking and not releasing fully when I release the pedal to recoil and as if a line is going to be filled with pressurized air to work again and it is not able to do so. If i wait and let the cars go far ahead of me and the blast without using brakes, there isn’t a need to keep using the brake m, but this is not how to drive in traffic and it isn’t safe. It also is scary to not rely on the function of my brakes and it is putting people at risk every day I drop my kids off or kick them up from school. I have had the brakes evaluated for repair, but I am told there is no issue with the brake pads or roters. No warning lights. It resolved after having my brakes evaluated and tires replaced, but it has returned.

Braking system becomes inoperable when the brakes are applied at the same time the forward collision system is engaged by the vehicles computer.

THE BRAKES ARE REALLY HARD WHEN PRESSING TAKES ALOT OF FORCE AND ALSO TAKES VERY LONG TO STOP NOW MY TRUCK PEDAL IS SOFT AND MY TRUCK IS STUTTERING FROM LOSS OF VACCUUM AND ALSO MADE ME FLY DOWN MY DRIVEWAY WITH NO WAY TO STOP

While driving in a parking lot to go thru a drive thru to pick food I was moving at a slow speed 10 to 15 mph and slowing to a stop my brake pedal became very hard to push and my Tahoe did not stop right away. I almost hit the car in front of me. I put the vehicle in park, turned it off, waited 30 to 45 seconds, turned the vehicle back on and put it in drive and slowly started moving in the drive thru line. When I stepped on the brakes to stop again the pedal got hard to push again and it did not stop right away. Brake Assist warning came on in the dashboard when I moved and tried to stop again. I drove home with extreme caution and as I was rolling into my driveway the same thing happened again that happened in the drive thru. I have parked my Tahoe and will have it towed to dealership.

HARD BRAKE PEDAL RESULTING IN LITTLE OR NO STOPPING POWER WHEN APPLYING THE BRAKES AT LOW SPEED. TO GET THE VEHICLE TO STOP, YOU MUST STOMP ON THE PEDAL AS HARD AS YOU CAN. THE SITUATION TYPICALLY OCCURS WHEN PARKING. THE BRAKE APPLICATION OR TWO ARE FINE, BUT AFTER THAT THE BRAKES FAIL. AND ALSO MAKE A VIBERATION IN THE BRAKE PEDAL WHILE SOUNDING ROUGH! WAS DRIVING TO WORK AND BRAKES PEDAL WENT TO THE FLOOR WITH NO PRESSURE AT THE PEDAL.

When driving at low speeds, the brakes are hard to engage which can result in crashing into objects/people without being able to safely stop. This happens in parking lots, stop and go traffic on the busy interstate and in drive-thrus. This can be dangerous for the driver/passengers and others outside the vehicle or objects. This is also a huge safety issue when driving down a steep incline at low speeds and having to pull out into traffic due to it not stopping appropriately. Vehicle has been inspected by a mechanic however there are no warning lamps illuminated. As stated before, brake issue happens only at low speeds. From my understanding there was a recall for this same issue for vehicles of certain years 2015-2018, specifically Tahoe being in the category.

Service brake assist system warning came on right after brakes malfunctioned.

I recently had my brakes and rotors replaced for this issue. Any time I’m backing my vehicle into and parking spot drive way garage etc it’s difficult to stop. I’m flooring the pedal to stop. I cracked my number because I couldn’t stop. I’ve seen an article for a recall on 2018 models that were made in 2017. My truck is a 2017 experiencing these same issues. No recalls are current for this isssue. Not sure if I’m the only one but it is happening.

heard a slight noise from the front of the car, like a faint squeal of a fan belt type noise. Then I had no brakes! No warning.. then a message displayed "brake assist service" A little late. No notice and almost plowed into the car in front of me! carefully crawled home and called AAA to tow it to the Chevy dealer.

The brakes do not respond at low speeds/stop and go traffic. There is a grinding noise and the car continues to move forward even pressing down fully on break. I had it checked in Nov 2021 for this issue and the dealership said it was the rear brake pads and replaced them. It happened again today so not fixed. No warning lights come on but I am extremely nervous as I almost hit the car in front of me as we waited at a light.
