My new to me ‘06 pathfinder is very unstable over bumps or road damage, especially if I’m not driving in a perfectly straight line. The front seems fine but whenever I go over any medium size road damage the rear of the car gets dangerously unstable and sometimes activates the stability management system (antilock brakes). This happens at speeds anywhere from 40 to 70 mph. The car has 25 k miles and General Grabber tires with pressures set at factory recommended 35 lbs. The suspension looks fine. Nothing’s bent or broken. I bought this as a Nissan Certified car 3k miles ago. What’s up with this thing??
