2016 GMC Yukon XL: brake failure

Filed Oct 18, 2024 · Brakes · CA

Driving back from Las Vegas for a family trip, traffic was heavy, a lot of stop-and go. I started to feel the brakes delay to stop. After a few minutes I was able to pick up a little speed and again traffic was built up. This time the brakes failed and got stiff. I had to slam on the brakes and practically stand up on the brakes in order for the car to stop. I barely avoided wrecking into the car in front of me. I was a few hours away from home and had to drive all the way with this problem. When I got home I took it in to the nearest dealer shop to get the brakes checked . I looked online and found out about the recall on the brakes.

Received a recall notice for my 2016 yukon xl, due to brake vacuum pump faulty. However mcgrath auto in cedar rapids, ia resolve to this recall was to simply reprogram the electronic brake control module. This was completed 12/19. By 2/20 my brakes were requiring me to push harder and at times sounded like they were skipping and braking felt delayed. I also was hearing a squeak/clicking sound coming from what seems the front of my vehicle engine area. Due to quarantine I was not driving or going places but once our state re-opened I called this dealership to report the brake concern and scheduled appt. A day before appt, while stopped at a red light as I moved forward in a very slow crawl my brakes failed me and I could not stop. I bumped the car in front of me which resulted in damage to both vehicles. I reported this to mcgrath as I was scared immensely about the safety of my vehicle. During the service appt 6/11/20 my car was diagnosed with a faulty brake vacuum pump. The vacuum pump was replaced and I was told I was still within the warranty . However they replace all 4 tires and claimed to recalibrate. On 6/25 while in colorado brake, ABS and cal lights lit up, the steering wheel power was gone, trailer brake system illuminate, (never even towed a trailer) called mcgrath from colorado as I couldn't drive my car, I explained what was happening, their resolve was to google gmc dealership in area for me. I found my own in cadillac/gmc dealership in boulder. My children and I are without a vehicle while out of state. Dealership in boulder diagnosed my vehicle with faulty electronic brake control module. I am furious as they say it will not be covered through warranty. My 2016 yukon is in impeccable condition, issues all happened upon recall with only 35,000 miles. My experience is exactly what is being reported by others impacted by this recall.

Vehicle was under recall and service was completed at gm dealer mid october. Following recall for brake vacum pump and new computer program, I lost my brakes on several occasions at slow speeds in reverse and forward. Vehicle was returned to dealer and after two days of testing vehicle would not duplicate issue or provide a code. Dealer returned vehicle. That day 11/05/2019 brake failure occured on two seperate occasions backing out of driveway on grade. Upon contact with dealer advised they would not do anything further until a code was provided. If I wished to replace the ebc vacum pump it would be out of pocket. Vehicle has been driven daily until another appointment can be made. On 11/13/2019 brake failure occured again on two occasions. When failure occurs pedal goes to the floor and what sounds like ABS noise is active with a pulsation in the pedal. Vehicle will not stop and have to use e-brake to come to a complete stop as braking distance is dramaticly reduced. A follow-up appoint will be made with gm dealer again.
