NHTSA Complaint #11097023 — 2017 NISSAN MAXIMA

THE CAR IS BECOMES UNSTABLE AND DIFFICULT TO CONTROL WHEN GOING OVER BUMPS, EVEN AT MODERATE SPEEDS (20+ MPH). WHEN GOING OVER BUMPS, THERE IS A LOUD THUMP / CLUNK / BANG FROM THE REAR SUSPENSION - AND THEN THE REAR OF THE CAR LOOSES TRACTION/STABILITY. NISSAN MUST BE AWARE OF A DESIGN ISSUE ISSUE AS IT HAS ISSUED A TSB TRYING TO SOLVE THE INFERIOR BUSHINGS IT CHOSE FOR THE REAR SUSPENSION - SERVICE BULLETIN NTB17-107. HOWEVER THIS DOES NOT SOLVE THE INSTABILITY PROBLEM. I FIND MYSELF DRIVING AT HALF THE LEGAL SPEEDS TO KEEP THE CAR STABLE - THE NEED TO SLOW DOWN FOR EACH BUMP IS CREATING A ROAD HAZARD. DRIVING ON THE SAME ROADS WITH MY OTHER CARS AT MUCH HIGHER SPEEDS (ROAD LEGAL SPEEDS), I DO NOT EXPERIENCE ANYTHING LIKE THAT. THE STABILITY CONTROL FUNCTION DOES NOT SEEM TO HELP AND IT LIGHTS UP FREQUENTLY WHEN DRIVING ON BUMPY ROADS. I FOUND MYSELF VEERING OF THE ROAD SEVERAL TIMES BECAUSE OF THE DIFFICULTY TO CONTROL THE CAR. THIS MUST BE A TERRIBLE AND DANGEROUS DESIGN FLAW. IN ROADS THAT I CAN DRIVE THE LEGAL SPEED IN A HYUNDAI SONANA OR TOYOTA 4RUNNER (45 - 65MPH) I SOMETIMES NEED TO CUT SPEED IN HALF WHEN DRIVING THE NISSAN MAXIMA SR JUST TO KEEP THE CAR STABLE ON THE ROAD.
