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.

While car was in operation, Intelligent Key System warning light came on (yellow "KEY" light). After turning off car engine, car will no longer start up. Key fob locks and unlocks doors, but car will not start. Prior to this incident there were no indications of a problem, no wornings. Upon investigation and research, the issue is related to a "Steering Lock Failure", and is widely known for years by other owners, repair shops, and Nissan and Infiniti. Nissan has addressed the issue by recalling and repairing the failure, however Infiniti has ignored the issue even though it is the same part (and same company). Infiniti must be made to repair the failure, as Nissan has done.

The supplemental air bag warning light came on the dashboard. My local mechanic coded it at B1018, occupant sensor failure. At his suggestion, I brought it to a Nissan dealership (Infiniti is over an hour away from where I live.). They indicated I need to replace both seat sensor and OCS module. They say the seat must be replaced. Checking the Internet, there is a recent recall for Infiniti air bag problems. I contend that if that same system was used in 2011, a recall of that year should exist. In addition, there are many similar issues reported on the Internet.
