2008 GMC Acadia Rough Acceleration Issue
At 40-50 mph, my 2008 Acadia has a rough/vibrating type noise when lightly accelerating. I took the vehicle into a local GM dealership and they thoroughly checked it and could not find the problem. This is very annoying and I will have to take this vehicle into another GM dealership for second opinion. This vehicle was purchased new and I've taken the vehicle in for all maintenance schedule requirements. Has someone else experienced anything close to this? I hate mystery issues when it comes to automobiles. I always felt competent GM service techs can troubleshoot these type of problems. I'm not giving up on GM vehicles, but if this problem persist, I certainly won't be buying another.
