Brakes Failed problems of the 2017 GMC Yukon

After a 7 hour drive on freeway brakes failed to stop vehicle. I had to have it towed to repair shop for a complete brake job for $1800. 00. Vehicle seemed to be fixed so drove it back home another 7 hours and the exact some problem happened again while parking in my garage.

After sending my SUV for the brake recall(the brakes actually failed while I was driving) last month, my brakes failed again while driving out of my driveway, on Wednesday 8/19 -on my way to work. . I drove straight to the dealership. Basically having to hard push the brakes on city streets stop lights etc. Scary. Yesterday, 8/20 they told me the car was fixed. On my way to the dealership 30 min away, they tell me after driving the vehicle, that brake indication came on the screen and they will need to keep it for my safety. As of now no word on it being corrected, and quite honestly not feeling safe about diving the car.

Brake failure after recall was done brakes still fail was driving and was braking the pedal went in all the way and the Yukon xl denali did not stop also have bad fuel injectors took it to the dealership and they dont know what fuel injectors go on the SUV also gm doesnt know they have to take apart the engine to find out what fuel injectors they put on the engine they wont give me a car rental and does not all the fuel injectors are on back order there is 3. Types high pressure low pressure and they dont know the fuel injector that was used I paid over 90,000 with taxes and interest on this 2017 Yukon xl denali and they have replaced 3 shocks, brake vacuum pump, brake and rotors they had to repaint the feont bumper rear bumper hood and back door and now the fuel injectors with only 37,500 miles this SUV is a junk and now I believe all gm cars are now junk.

My husband and I were driving on the highway at 70 mph when he needed to slow down and noticed the brakes on the Yukon were not functioning properly. More specifically, the brakes would not function the first 3-4 times when they were applied or tapped, but thereafter the brakes would become hard and he had to depress the brake pedal as hard as he could but with little to no stopping ability. The �brake assist� light came on. Had we been in any traffic or on a shorter road, we would have surely crashed into someone and it could have been catastrophic considering we live in dallas where there is a lot of traffic. This day we were very lucky! gm had issued a service bulletin #pit5361b which affected multiple years and classes of vehicles to include the 2015 Yukon. Gm acknowledged that �a customer may comment on a hard brake pedal or that increased effort is needed to depress the brake pedal. � as evidence of the defect, gm notified its dealers, �while performing normal diagnostics, fluid may be found in the brake booster and/or the booster vacuum line. � however, we called multiple dealerships within the dfw area and they all denied knowing any issue with gm brakes failing or the vacuum pump. Interestingly, there is a class action lawsuit on this very issue and gm also issued a series of service bulletins to its dealers regarding the brake defect, with the latest bulletin dated March 15, 2017, to include the 2015-2016 Yukon. Ours is just a 2017, 1 year outside of that. Who is to say this year isn't affected considering past history of the bulletins. It was thanksgiving holiday and no dealership could even get to it besides not knowing of any �issue�, even though it's all over the internet.
