Have gone to dealer multiple times with this issue. When driving at speeds between 20 and 40 mph the car shutters. Once past 40 goes away. They have done these software updates, checked tires, I had injectors cleaned and had new plugs put in. Has not fixed. It won’t throw a code so they don’t know what it could be. I had a 150,000 mile warranty which is now up. I have 158,000 all highway. Yes a lot but still should not be happening. This entire issue was documented well before warranty was up. Anyone else have this issues.
