I've had no problems with the seatbelts so far, but I do have to be careful in getting into the drivers seat. I have a key ring on my left belt loop and at first, I scraped the leather seat corner when I entered, which immediately made me sick...so I feel your pain. I too love my Volt, I think its the best car I've ever driven...and that includes luxury sedans from Europe..the volt rocks....You may find it helpful if you reached across with your right hand and grab the seat belt, this will allow you to guide the buckle into the receiver, hope this helps.....
