I am at about 1 year of ownership on my P85. Just starting a day ago my car steers a little loose and fishy. Like driving a big boat of a car. I thought it was tire pressure so double-checked and topped up the tires. Still feels the same. It is much more noticeable at highway speeds where there is delayed reaction to steering input and then it feels like it over steers. It is a little scary to drive at high speed. I thought I had a flat tire at first. Any thoughts on what could be causing? Does this sound like an alignment issue or something else?
