Kia Troubleshooting Questions? Ask a Mechanic
Hi. Have you checked all the tire pressures? They come really high from the factory and need to be set when the vehicle is delivered. This may not have happened.
Ok. I do not think that 2 pounds is enough to give you that feeling on the highway. I have drove many 2016 Sorentos and have not noticed this problem. It still could be caused by the alignment, although there should be no reason for the alignment to be out on a brand new vehicle, but it can happen. Since you already have set the tire pressure, I recommend that on your first service you tell the dealer about this and the will look into it under warranty at no cost to you.
I understand it is brand new and it is unfortunate you are having that problem. You are welcome and let me know how it turns out. Please rate my assistance using the 5 star rating method, and have a great day!
