NHTSA Complaint #11493542 — 2018 MERCEDES-BENZ GLA 250

In July 2022 I was a few miles from my home when the cluster starting showing warning lights. It started scrolling inoperative power brakes, inoperative steering and inoperative parking. Also the cluster was completely lit up. I turned the car around and put it in my garage. This is where the issues really started. The car would not go into park or turn off. I sat with my foot on the brake for 30 minutes trying to continue turning the car off or put in park. I finally had my wife take the key and walk 1/8 mile away before the care would turn off. I had the car flat bedded to Mercedes of Cherry Hill. They had the car for several days. They called me and asked if the car was flooded or hit. I told them no to either. I explained how the car is garage kept. I was talking to my mechanic who services the car and started telling him the story. Before I could say anything he asked me if they asked me if the car was flooded? I said how did you know that? He told me that he has several customers with similar issues with the wiring harness in the front bumper. He told me that it's a bad design where water gets in and burns the harness out. The scary issue is the car not turning off or going into park. If my wife who drives the car was by her self had this issue what would she do?
