2011 Infiniti G25

I was having gas mileage issues and had an engine light come on one day. I checked it for it to come up with mass air flow sensor code. I had them replaced. Once I replaced them I noticed I still had the light and mileage issues. I did some research and found out you need to reprogram the sensors at a dealership after replacement. I scheduled an appointment at Infiniti of Akron and they reprogrammed them. I left and a couple hours of driving later the acceleration is worse and mileage is bad. The engine light comes back on. I call back they check my ECU and said I was missing an update. They couldn’t do the update due to their systems being down at the time and told me they would call me when they were ready. I left to head home. I hopped on the highway towards my house. After about 10 minutes of driving my car begins to slow down to a complete halt and stalls right in rush hour traffic. I had no where to safely pull over. There was no shoulder available due to construction. I immediately called 911 to assist me to get an emergency tow. I eventually ended up being rear ended by a car. A fire lieutenant stayed with me for about 2 hours to ensure I was safe until the tow showed. This was a terrifying incident and should be noted. People need to be warned their is an intake volume learn problem with the ECU of these vehicle. People could be killed. I was lucky.
