My 2014 Volt over an extended highway drive over Thanksgiving felt like the steering was getting stuck while cruising straight at 75mph. The car when needing to correct stay in my lane felt like there was "dead spot" and then it would stick until I turned the wheel harder. I thought this was happening in the past but it seems to be getting worse. I saw that there is a technical service bulletin # 14232 for a software update. When reading about it this was my problem exactly. Any thoughts on this matte, experience, or if I can just call the dealer up and give them the bulletin number. The car is still under the 3/36 number to number as it has 24,500 on it.
