A message keeps popping up, -€œtrailer brake system-€ it is poor wiring on GMC part. I did research on this and looked it up and other people had similar issues which can be very severe if driver continues to use after this message pops up. The message is so continuous that it could distract the driver, which could lead to a fatal accident.

While I was in line at the gas station to get gas, I moved up because the car I front of me had done so. After moving up a bit, I pressed my feet on the brake but the pedal was very stiff and the breaks did not hardly engage. I almost ran into the vehicle in front of me. This was very scary. So I called for a tow truck to pick me up but after a while they didn-€™t show. I started my car up to see if the the brakes engaged and they did. So I slowly and carefully drove myself to the GMC dealership in Southaven, MC which was 0.3 mile away from the gas station. The GMC dealership said that it was vacuum pump that was at fault and admitted it was a recall for this. But they said since my truck has already been serviced for this recall that I would have to pay to get it fixed. This is absolutely absurd. If the issue was not fixed properly in the first place, why would I be responsible for getting it fixed the second time?

Last week, the power brake assist began fading away intermittently at low speeds, and caught my wife off guard in a grocery store parking lot when she pulled into a parking space and the brakes were not available. She had to plant both feet on the brake pedal in a panic stop before crashing into the car parked in front of her, and has since never driven the vehicle. This is a danger, and is potentially life threatening.

Brakes are not stopping the vehicle on short distances as it should. They are doing a clicking kind of noise and can feel pulses in the brake pedal as though ABS are trying to activate. I know there is a recall out but is saying my 2015 is not listed yet is doing the same thing that is described in the recall.

First note that our recall for increased pedal effort was done on our 2015 GMC Yukon 2 months before this incident. Our vehicle was traveling at a high rate of speed coming home from mammoth on the 15 freeway. We heard what we describe as a 'buzzing' noise but we couldn't tell if it was our car or another on the freeway it almost sounded like tire tread before you have a blow out. We slowed down a bit (65-70mph) to check our surroundings. A few minutes later we started to lose control of our Yukon. I started to unbuckle and climb to my husbands drivers seat because he wasn't responding to our screams and he looked ill. As I was screaming his name he finally says into my ear we have to crash! I panicked and screamed what is happening. He replies 'we have no brakes'! the pedal was as hard as a rock like a brick was underneath it and our car was serving back and forth. As traffic slowed and we prepared to crash into the car in front the center divider opened up and we were able to cruise down it until we slammed E brake on. These models should not be on the road and we could have very easily died or killed another family in the process! absolutely unacceptable on gms part! terrifying! there has been no vacuum pump recall placed on our Yukon and it was the vacuum pump that failed which made the brakes fail there was no back up zero brakes with a family of 5 in the car on the freeway! every owner who owns a 2015/2016 should be aware that this can happen to them. It's not just at slow speed. We haven't stepped foot in our car since our kids are scared to death to ride in any car that looks like it.

There was a recall for low break failure it was recall 19V645. I had this done last year and today I almost hit a car in the drive through side the brakes are still doing the same thing going to the floor. They need to replace the faulty vacuum pump. I experience this while backing out and stopping at slow speeds.

I bought my GMC Yukon in March of 2019 about a week later I had people inform me my brake lights were not working. I would check at night and they would. A few months later I noticed it myself, they would work one minute but not the next. December of 2019 I get a letter from GMC stating they know 2015 model GMC Yukon vehicles may have a condition where the brake lights intermittently do not illuminate. I could have it done if my SUV was not over 72K miles but it was when I bought it. So that doesn't help me and they want $2K to fix it. I called to see what they could do and they told me this wasn't a safety issue. If they do work and someone doesn't see I am braking, my kids or family are in the back seat, how is that not safety related? they need to make this a recall!

The tail lights stop working or they flicker like there's a loose connection or something not making contact I E seen other complaints about the same thing and GM now has a new improved tail light but the old ones all fail all stop working. On the braking system it doesn't brake when going a low speed without giving it gas I have to pump N push the brakes all the way down or give it a lil gas to be able to stop or brake the lights flicker or stop working while driving stop all the time the dealer wants 1500-2000 to replace em the lights.. they are defective and should be recalled their bad workmanship shouldn't be mine our anybody else that has this vehicle burden this is not a cheap vehicle I paid over $50,000 used for about a year.. I need your help. The brakes need to be fixed also because at low speeds with no gas on the pedal I can roll into something hit something or someone.

Tail lamps would intermittently operate. At times none would work at others some would work. And others all would work. GMC finally addresses this with: N182180270 (special coverage). GMC was aware of this issue on or prior to November 26, 2019. They stated notifications to customers would begin on December 12, 2019. I was notified today 2-12-2020 well after GMC was aware of issues. GMC allows for warranty of 6 years after placed in service or 72,000 miles. Since my vehicle had 902 miles at time of purchase my warranty expired at 72,902 miles. Had GMC made me aware in December or too after knowing in late Nov 2019 I would still have been under warranty for a resolution to fix issues. There willful negligence in failing to notify me hindered their available warranty under special coverage of no use to me to my detriment of several hundred dollars (~$1800 usd).
