05' G35 coupe 6MT. I took the car to infiniti.. couldn't duplicate the problem (of course). But they replaced my NAT sensor and reprogrammed my keys. 3 days later the car still has the same issue.

Basically, my car will randomly be in security mode. When I turn the key, I can actually see that the alarm light is solid. The engine will turn over but won't start. When it does this, it seems to take anywhere from 10 minutes to an hour to "reset" if I leave to alone.

This mostly happens when I make 2 or 3 stops.. i.e. turn the car off while running errands etc.. when I restart the car the 2nd, 3rd, 4th consecutive stop, the alarm system will kick in, not allowing me to start the engine.

Sometimes it won't happen in a whole day. Sometimes It will happen the first time I want to restart the car from running just one errand. Lately.. I've been leaving the car running when I make a stop so I wont be stranded.

I'm thinking I might have a starter problem?

Lately, I've been experimenting with my bluetooth phone.. perhaps I'm getting wireless interference?

I'm on my 3rd engine (oil consumption). The irony is that the new engine is not burning oil.. but the trade off is I have to be stranded randomly every now and then.

I'd rather be consuming oil again.

 

Wow - give it to the dealer and let them start and stop it a bunch of times during a day or two until they figure it out. I couldn't stand for that s*#t - when I turn the key I need the car to start every time.

 

I'd rather not have them drive my car around like that, but I might not have any choice.

 

no you didn't have any choice, and i fixed it didn't i
