So, I've had this 2026 Civic Sport Hybrid for 3 weeks now, bought the car brand new, I'm having this issue where the car wanders excessively at highway speeds. Before you guys say anything, yes, I know compact sedans may wander in the wind or next to a car/ semi, but this feels excessive to me. It's bad to the point that other cars have to make space for me even when it's not windy. I have to make constant microadjustments on the highway, and I have to tightly grip the steering wheel on the highway so I can adjust to minimize sway. It can either be a car or semi that passes me—I lose control (not enough to crash into them but still excessive); either I'm pushed back to one side or I pull into them. This happens left to right. I went back to the dealer I bought it from yesterday, a shop guy test drove it at about 55-65 mph near this street way, and told me it looks like nothing is wrong with it. I'll be going back middle of next week for a full inspection. It didn't happen right then and there because it was Friday and the receptionist put me on the schedule during a time when they were fully booked. I'll ask to go on a test drive again, but this time on the highway next week. I'm just explaining this to let you guys know that yes, I've gone to the dealer about the issue. There are no recalls on the 2026 model currently. I'm wondering whether you guys have experienced this? What was it? Any ideas?
Edit: I got a tire alignment prior to going to the dealer or making this post. This issue is still present.
