I hate this as my first post, but my truck did the same thing yesterday, and I just bought it last Friday. I’ve owned many new vehicles in my life, with this being my first GM product. 2023 Silverado 2500 LT gasser, 261 miles. I really enjoyed the truck for the first miles, but I am livid. Had it towed to the dealer yesterday, no replies from them yet. I will be calling in the morning. I traded in a 2022 Tundra which I wasn’t impressed with.
