What 2011 Infiniti G25 owners say
Electrical system
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. …
While enrooted to work my vehicle just shut off unexpectedly. I had the vehicle towed to nearest mechanic shop and they could not find out why my vehicle stopped, then the vehicle started back up and I drove the vehicle home. A few days later on my way to work again, my vehicle would not start at all. I had AAA come out to try and start the vehicle thinking that it was a dead battery, but I was told that the battery was in good shape. A few days later my vehicle started once again, so I took it to another mechanic shop and was informed that it was possibly the key fob, then the vehicles onboard computer. They proceeded to troubleshoot the vehicle thinking that this maybe the issue, then the vehicle would not start once again. It was not any of the issues that they thought. The vehicle was taken to the dealership to find out what was going on for sure. …

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.
