When I first bought my Prius Plug-In Hybrid in 2014, handling was fine in the city but was awful at highway speeds. If I held the steering wheel still, the car would start to wander out of its lane within seconds. There was no pattern or “pull” to the left or right; it just didn’t stay straight and therefore needed constant steering corrections to stay in its lane. At 70 mph, I felt like I was constantly driving on slick roads even when they were bone dry. I took it back to the dealer who checked and adjusted the alignment and toe-in.
Fast-forward 4 years: The same problem has been slowly returning. I now feel as if I am driving on wet or even snowy roads when the highway is perfectly dry and clear. I find myself slowing down much more than other cars (and more than even the yellow recommended speed signs) on highway turns. I just got it aligned again, but the mechanic said that the alignment was already nearly perfect. He also said that the tires are in fine shape with no damage or uneven wear. So, I’m at a loss.
Has anyone else had this issue? Suggestions / Advice?
