I WAS DRIVING FOR FIRST TIME AFTER BUYING VEHICLE ON THE HIGHWAY AT AROUND 55 MPH AND THE REAR OF VEHICLE BEGAN TO BOUNCE PU AND DOWN ABOUT TEN BOUNCES. IT HAPPENED AFTER GOING OVER AN UNEVEN SURFACE, BUT NOT A BUMP. IT WAS VERY ODD. I HAD SOME DISCOMFORT IN MY NECK AS A RESULT AND A GENERAL UNEASE OF WONDERING WHAT WAS WRONG WITH THE SUSPENSION AS WELL AS A FEAR OF LOSING CONTROL OF THE VEHICLE ON THE HIGHWAY. THIS HASN'T HAPPENED AGAIN ALTHOUGH THE EXCESS IN BOUNCINESS AND THE VERY UNCOMFORTABLE RIDE OF THE VEHICLE HAS CONTINUED AND GIVES ME NECK PAIN EVERY TIME I DRIVE IT AND I'VE ONLY OWNED IT FOR ONE WEEK. IN MY VIEW, EITHER MY PARTICULAR VEHICLE SUSPENSION IS FAULTY OR THERE IS A GENERAL ISSUE WITH DESIGN OF SUSPENSION. *TR
