I HAVE NOT YET HAD AN ACCIDENT BUT I DO NOT UNDERSTAND HOW THIS PROBLEM HAS NOT BEEN RESOLVED. I OWN A 2003 INFINITI FX-35. THE SEAT HAS A ROCKING MOTION TO IT. IT ROCKS BACK AND FORTH WHEN I ACCELERATE AND BRAKE. THE DEALERSHIP SAID THIS IS A PROBLEM THEY ARE RESEARCHING. AFTER 7.5 MONTHS I AM CONVINCED THEY ARE JUST BLOWING ME OFF.

THANK YOU FOR YOUR ASSISTANCE IN…
