My automatic 05 G35 keeps going into limp mode. I lose all my power and my gears won't shift. My RPMs escalate at the same rate that my speed does but doesn't shift. I took it to a mechanic and it is putting out codes for my "suspension pressure switch" and my "front brake pressure switch". I took it to a transmission specialist and he said it wasn't my transmission itself, it was the computer in it. I've checked my battery, changed my battery terminals, and have done a reset on it a bunch of times. After the reset the car will drive fine for about 1 or 2 minutes then the Service Engine Soon (SES) light will turn on and then I'm back to where I started. SES light is on, no power, car won't shift. I'm all out of ideas and need some help.

Have you thought about letting a Infiniti dealer diagnose your problem?

The "Stealership" isn't a great idea! Since it's putting out codes a trip to Nissan will solve your limp mode issues! Nissan charges 30% less than Infiniti, from what I've noticed their mechanics are better trained too...Gary
