The contact owns a 2017 GMC Sierra 1500. The contact stated that while driving approximately 55 MPH, the vehicle started losing motive power. The accelerator pedal was depressed and the engine revved; however, the vehicle failed to respond as intended. There was no warning light illuminated. The contact pulled over, and after several attempts, the vehicle restarted. The contact was able to drive the vehicle to a local dealer and failed to exceed 10 MPH. The dealer was able to diagnose the vehicle and determined that the torque converter had failed and needed to be replaced. The vehicle was repaired. Additionally, the contact stated that while driving approximately 35 MPH, the vehicle started vibrating and stalled. The contact stated that again, there were no warning lights. The contact was able to restart the vehicle and drove the vehicle back to the same dealer. The dealer diagnosed the vehicle and determined that the fuel injectors had failed and needed to be replaced. The vehicle was repaired; however, the fuel injectors failed, and the contact had taken the vehicle to a different dealer. The vehicle was not yet diagnosed or repaired. The contact stated that while driving approximately 65 MPH, the brake pedal was depressed but was difficult to depress. The contact allowed the vehicle to coast and was able to pull off the road. The contact slowed down to approximately 2 MPH and was able to use the parking brake to stop the vehicle. The vehicle was turned off and restarted to reset the braking functionality. The contact was out of town and took the vehicle to a dealer to be diagnosed and repaired. The manufacturer was informed of the failure. The failure mileage was approximately 24,000.

I was test driving this 2017 Sierra 1500 SLT and experienced issues while braking. Issues with brakes as the vacuum level drops the brake assist decreases which meant I had to use excessive force to get the vehicle to stop. No warning light, nothing to tell me there is a low pressure brake. This could result in a fatality if a small animal or child walks/runs in front of the truck while truck is moving forward or backwards at low speeds. The dealer doesn’t acknowledge any recall on this vehicle because it isn’t noted as such with GM. I worry that all of the other recalls (4 others) may be an issue too, which include Frontal Airbags not deploying during an accident, faulty wheel sensor causes opposite wheel to engage and cause the vehicle to pull to one side, fuel leak, and child seat anchoring restraint instructions not included in the owners manual.

2017 GMC Sierra almost hit a parked car in the store parking lot. Pedal was hard push down . Also when moving truck around in my yard at times the pedal is hard other times sounds like there is Air in the lines. Truck has all new Brakes and Rotors all the way around. I pull a Camper and Side x Side at times so this is scary.

My 2017 GMC Sierra Brakes started acting up a slow speed it would seem like there were no Brakes or Pedal would push very hard. I pulled into a parking space at the store and it was like I had no Brakes had to push pedal very hard and Thank god there wasn’t a car in front of me because I would have hit it. The truck has new front and back Brakes and Rotors put. The truck was throwing some codes and 3 out of the 4 codes pointed to faulty Vacume pump. I pull a camper and sometimes a side x side so this is very concerning and I hoping to get this expense covered by Recall like all the other Models with the same issues. I really don’t know why my truck isn’t being Recalled. This has been a good truck for me no complaints tell this.

I was slowing down in a parking lot to park. I applied the brake and the pedal was very stiff and the vehicle wound not stop. I finally stood on the pedal and it acted as though the antilock activated and started shuttering. It finally stopped without damage. A warning of service brake assist displayed on the dash. This began to happen about 3 months ago intermittently, but now is a more frequent action. I have not taken it to the dealer and thought of replacing the brake vacuum pump but don't know what to do. Any assistance you can provide will be greatly appreciated. Thank you and have a great day! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Brakes at low speed do not work well, causing extended braking distance. Looks to be a previous vacuum brake pump issue, but is no recall on it now.

THE AFFECTED VEHICLE IS A 2017 GMC SIERRA 1500 4X4 CREW CAB TRUCK WITH LESS THAN 34K MILES. WHILE DRIVING THE VEHICLE TODAY THE BRAKES BECAME VERY HARD, LIKE A LOSS OF POWER BRAKES. FELT LIKE THERE WAS A LOSS OF VACUMN. AT SLOW SPEED IN REVERSE THE BRAKES "SHUDDERED" WHEN APPLIED. HAVE NOT TAKEN IT TO A DEALER AS IT JUST HAPPENED WHILE TRAVELING. CHECHED FOR INFORMATION FOR SYMPTOMS ONLINE AND FOUND GM HAD INITIATED A RECALL FOR THIS ISSUE SO I CHECKED THE NHTS WEB SITE TO SEE IT MY VEHICLE HAD A RECALL. SYSTEM INDICATED 0 UNREPAIRED RECALLS FOR MY VEHICLE. SO WANTED TO REPORT THE ISSUE.

Incident

Aug 3, 2024

My vehicle has on two separate occasions experienced a failure where the steering locks up, the engine shuts down, and the dash displays warnings about stabilitrac and trailer wiring. The vehicle has had random electrical glitches for some time, but they have escalated to a safety issue. In doing research, my issues sound very similar to those issues which resulted in a recall to earlier vehicles of the same generation, on report 17V-414. Googling the issue also points to insufficient grounding at the battery and / or the G218 grounding connection.

Incident

Feb 3, 2024

The incident occurred on [XXX]. My vehicle has 54,571 miles on it. The power brake assist function failed. I was backing into a parking space at a local fast food chain and experienced near brake failure. I had to stand, nearly full body weight pressure, on the brake pedal to get my truck to stop at very slow speed. I, again, backed a short distance of a couple of feet at the most and experienced the same issue when I tried to stop. I placed the vehicle in PARK and turned the engine and ignition key off, thinking the system possibly needed to reset. I started the truck and drove forward, very slowly, to another parking space and applied the brakes. I experienced near total brake failure again. I had my truck into Brogden GMC in Olathe, Kansas on [XXX], for general maintenance and a “brake pressure recall.” I had experienced a slight brake pressure issue on a couple of occasions prior to the recall. After the recall service was performed I did not experience a braking concern for some time. I did experience “soft braking” a couple of times after the recall was performed and attributed it worn brakes. On [XXX], at 50,596 miles, I upgraded my brakes by installing a Power Stop Z36 brake kit with slotted rotors and ceramic pads. I have not had a repeated experience of soft braking or brake failure until the [XXX] incident that I am currently reporting. It appears to me that the earlier recall did not completely address the brake failure issue with my 2017 GMC Sierra 1500 pick-up.

It takes quite the amount of force to stop the vehicle brake pedal started feeling spongy and seems like it doesn’t have enough pressure constantly I have no brake fluid leaks or air in my lines it all comes down to the brake booster it seems like and I know a few vehicles had this problem but mine says it wasn’t but I believe it has been affected.

Service Trailer Brake System. This has happened in the past 3 Times, in which the local GMC Dealership has made me pay for New Batteries and other Fuel system issues. Dealership stated that this shows up because of a bad battery.

At low speeds the brake pedal gets hard and it feels like the antilock brake system is activating, I believe this is the issue with the Brake booster vacuum pump. GM isn't calling this a safety issue.

Incident

Brakes intermittently quit working at slow speeds. Sometimes while pushing on the brake pedal, the brakes don't respond, I have to increase the force placed on brake pedal. There is also a pulsating sensation at the pedal like the ABS is being applied, even though I am traveling at slow speeds, and it takes much longer to stop the vehicle. There are no warning lights that come on and there is nothing on the message center stating there is an issue. Has happened multiple time, usually in a parking lot, or in stop and go traffic. Also has happened when vehicle is in Reverse. Have never had the issue at highway speeds.
