  • 2015 GMC SIERRA 1500
    - Pine Island, MN

    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 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.

  • 2015 GMC SIERRA 2500
    - Livingston, TX

    Shifting started to make a loud clunking sound. Then the vehicle wouldn't shift out of 3rd gear. The engine check light came on and the code determined it to be a faulty transmission control module (TCM). When looking at the TCM, I also noted that the TCM was very hot and the nearby cable cover had melted. When researching the issue, it was discovered that GMC Sierra 2500 and 3500, years 2009 - 2015 were having this same issue all over the continent. Resulting in a massive back order and leaving drivers stranded. There was no warning lights or sounds before my power train froze up.

  • 2017 GMC SIERRA 1500
    - BROOKLYN, MI

    Truck all a sudden developed a Lifter noise under the hood and the check engine light came on Friday, September 8th. I checked the oil and oil pressure which was ok. Saturday morning 9/9 I notice some loss of power pulling out on Highway. I took the truck immediately to a friend who is a retired GM Master Mechanic. He coded P0300 and P0306 with 158 miss fires. The following Monday on September 11th I took the truck to Clift GMC in Adrian, MI. They confirmed a Lifter failure and bent Push Rod on Cylinder six. on my 5.3L engine. Since I have learned the AFM System on these engines is driving Lifter Failures. I was lucky my Camshaft was not harmed. My truck had 84,945 miles on it and is six years old. GM offered no, zero assistance. The Dealer could only state this is a well known issue which they see frequently offer a extended Power Train Warranty at a cost of $1600 t $2000 dollars. How is a Extended Warranty a solution to a poor Engine Design? Help!
