The vehicle has had steering and alignment issues since the day I purchased the truck. The steering wheel is not centered. The steering wheel is always turned to the left but the vehicle pulls to the right. I have had it at my local dealership five times and they have confirmed what I have described but they are not able to fix the issue fully. They have rotated the tires 3 times and have aligned it all five times. The vehicle will be good for about 100 miles and will go out of alignment again. The dealership explained to me that they are experiencing this with all 2024 Chevy and GMC heavy duty trucks. The vehicle is very difficult to keep straight especially at higher speeds on the interstate. I am part of a 2024 Chevy and GMC owners facebook page and hundreds of consumers are complaining of the same issue.
