  • 2024 GMC SIERRA 1500
    - Prairieville, LA

    The front upper grille deflector detached and hit my windshield and bounced off behind me during a drive at normal highway speeds. This created a random flying debris object that appears to have been a problem with the 2022 and later Sierra 1500 models; however, the recall only appears to address the 2022 model. It also appears quite common for the 2024 year model as well. Vehicle has never been in an accident so nothing beyond typical use would have caused damaged to the connections. The plastic connectors appeared to have failed.

  • 2021 GMC YUKON
    - McAlester, OK

    My 2021 GMC Yukon AT4 with a 5.3L engine failed as I was driving down a highway going to my child's ballgame. It put me at risk of wrecking on the highway with other traffic around me as I needed to get my vehicle off the road way. Thankfully, I was able to get the vehicle to a safe spot to get it towed. After having the vehicle towed to my local GMC dealer, they determined my lifters in my engine failed and my camshaft had irreparable damage. GM has a lawsuit going on right now against their faulty lifters in their engines. The dealership told me they recalled the 6.2L engine, but not the others. It is shameful that they haven't recalled the other engines that also have the same lifters with the same active fuel management system. My power trained warranty has just expired and they want to charge me over 15,000 to replace the engine and radiator. I am now fighting with GM to help cover this expense that I feel a recall should take care of. These vehicles are not safe on the road with these faulty engine systems specifically the lifters inside them that are known to fail and GM is aware of this and not doing anything. Please help me and other GM owners get these vehicles recalled and make GM replace these engines at no cost to the owner due to their faulty engine components. My daughter and I could have been seriously been injured or died that day in the highway due to the abrupt engine failure on the highway going 70mph. Thank you for your time and God Bless.

    I took my GMC Yukon in for a recall. They changed the oil, programmed my module, changed the cap, and tested the engine, saying it was good. I took it on a trip, 7000 miles later engine locked up.
