NHTSA Complaint #11625737 — 2016 GMC SIERRA 1500

Paint bubbling on roof. When turning on key, the radio makes a loud buzzing sound. On 11/16/2024, when leaving a traffic light, the truck began surging and shuddering. Tachometer was revving up and down like the transmission was slipping with loss of power while trying to take off and accelerate. While attempting to return home, loud booming noise was coming in from under floorboard. I was unsure if I would make it home before the transmission totally failed. People were passing around me because I was unable to acceleration fast enough because of the shuddering and loss of power. No previous signs of any powertrain issues or failures before. It happened for the 1st time today, and my truck is no longer safe to drive. GM has known about this transmission issue for years on several different models and has failed to broadly rectify the mechanical problem on all affected vehicles. Instead, GM has allowed the vehicle owners to continue to drive a vehicle with a known problem while it waited for a failure. This put me and my family at risk because I am driving around in a vehicle with a known transmission problem not knowing when it would fail or where I could be located when it failed. GM needs to pay for all repairs on all vehicles with this transmission failure because GM has known about this problem for years before someone gets hurt or killed. GM knew about the shuddering problem from the beginning, and they fixed the problem by tuning the transmission which then caused the total transmission failures over time which vehicles owners are not dealing with. Metal shavings are being located in the pan when inspected. GM should be held responsible for the cost of these transmission repairs. I would have never purchased the GMC Sierra 1500 if I have known GM was installing defective transmissions in new vehicles. That is shady, reckless, and unsafe. GM, pay to fix these problems.
