The brake vacuum pump is failing. When in a parking lot the brakes get very hard al.ist causing an accident. There is no vacuum when trying to park in parking lot. The 2015 GMC Sierra had a recall for this but my VIN did not. Not sure why as it's failing too. I need my truck so will have it fixed today, but want a recall.

At low speeds, like parking it lost all brakes. I have noticed a few times since the first. I see they had a recall for the brake vacumm pump but I cant find much on
Brake vacuum fail, causing the brake pedal to become stiff and unable to stop the vehicle. This issue has been on the recall for the same year and make of truck as mine, yet mine is not eligible for this recall repair? Please help Thank you
The Truck has something wrong with the Trailer braking system. with no notice it display "Service Trailer Braking system" in the DIC. This will cause loss of brakes to the trailer and make it very difficult to stop with the trailer. Everything functions properly and at a random moment they will just stop working.
Purchased GMC Sierra C1500 new in 2015 from a dealership in Orange County, CA. Experienced multiple issues over the past 4 years with the "Trailer Brake System" Service light and loud beeping which has created multiple safety issues making the vehicle undrivable at times. The last incident was while on a cross country road trip through extreme heat in the Southwest from Texas to California in June and most recently while visiting Orange County. The beeping noise almost caused a couple of accidents as the hands free phone system was inoperable due to the loud warning beeping noise as it went on and off about 50 times. We were required to take several risky maneuvers to pull the vehicle off heavy highway traffic at high speeds to stop the engine and restart in an attempt to reset the warning beeping system without success. The truck was checked in for service on 07.20.2022 at Tustin Buick GMC. Mr. John Boozer, Service Advisor. 714.669.3699. The total cost of repairs is $465 plus car rental of $80. Additional costs in April of 2019 for the repairs included fuse replacement, check of wiring harness and attempt to stop the beeping noise was $150. The defective wiring harness originally installed by GMC when the truck was built will be preserved and is available should your agency request it. Total costs out of pocket to replace or fix this factory defective part is $695. GMC has made no effort to address this issue or offer any recall notices related the failure of the "Trailer Brake Warning System". Thank you for your attention to this matter.
On July 18, 2022 my trailer brakes suddenly stopped functioning ( a few hours from home) Not only did did the trailer brakes stop functioning, but this warning message didn't popped up just one time, it kept coming again and again and again and again, relentlessy chiming and distracting me from driving. it covered my speedometer readout. it prevented me from receiving or making voice commands. the service warning chime also prevented the turn signal from functioning. So for a full 4 hours I was constantly reminded and was unable to receive calls or make voice commands. i absolutely wont hesitate to say the vehicle was not safe to drive in that condition. your vehicle's defect endangered my life. I will not hesitate to say your vehicle was not safe to drive in that condition. Your vehicles defect endangered my life! Lastly, my vehicle did not want to start the next morning!!
My truck has just over 54,000 miles on it. I bought it new and have treated it well. It's my "Sunday" truck. Without warning, yesterday while carrying my wife to a doctor's appointment, as I pulled into a parking space to park... I had almost no brakes. I actually jumped on the emergency brake to aid me in getting stopped. After my wife had gone in for her appointment, I slowly moved the truck around the open areas of the parking lot trying to figure out what the problem was. I checked the brake fluid, looked to make sure I hadn't lost a brake pad or something else weird and found that everything was good. What I did find though was that the only time the truck had any issue was when I was moving under maybe 4 or 5 mph. And in fairness... I discovered the truck did have some tiny (but I do mean tiny) amount of braking ability at that low speed, but to say that the experience was unnerving would be a terrible understatement. Had someone been standing between me and the vehicle I was parking in front of when I experienced this, there is absolutely no doubt in my mind that I would have pinned them between our vehicles, or God forbid, something worse. I don't know what's going on here, but there's definitely something going on with the brake system at low speed on this GMC.
