NHTSA Complaint #11520689 — 2013 HYUNDAI ELANTRA

Since I purchased this vehicle in 10-2012 I have had major suspension tracking issues. When driving at normal highway speeds (50-70MPH), the slightest bump in the road makes the rear of the vehicle sway and "dog walk" . This has been an issue within the first few months of ownership, but the dealership found no issues. The situation started shortly after purchase and continues the same as of today (5-5-2023). I have replaced the rear shocks with better than OEM shocks and continue to have the same situation. If the bump in the road happens to be in a slight curve (such as an expansion joint in bridge) on the Interstate, the vehicle nearly looses complete traction. This happens with new tires and on dry, warm concrete. I have spoken with other owners of similar make and year and all have said they had the same issue, even right after purchase. No warning lights, traction control lights or messages appear on display.. I have had multiple inspection stations and garages check out the suspension and wheel units, but no malfunctions or defects found.
