NHTSA Complaint #11431324 — 2008 MERCEDES BENZ ML320

8/1/2021 accident involving 2008 Mercedes ML320 CDI >recall faulty tow hitch< Mercedes has refused to conduct an investigation and resolve these damages. While injured (both myself and 9 yr old son w/ a heart condition), no serious injuries or fatalities happened during the accident. It resulted in totaling the vehicle and our camper. Recall doc's show that Mercedes of New Orleans completed the recall; however, they either falsified disclosing they did the repair or conduct poor workmanship when repairing the hitch. While driving the hitch broke/cracked resulting the camper flipping over and slamming into the truck. I have photos along w/ consulted w/ certified welder confirming the weld was not properly done. More photos if needed.
