Hello all ! wondering if you guys could help me out.
I drive a 2008 G35XS, today when i went out to start my car the brake pedal was very stiff and when I pushed to start, my car would not start, but a couple of lights on my dash would blink... it was super cold today in Edmonton (-30 degrees celsius) .. so I'm thinking thats why???? It was driving fine until this morning.

Any suggestions would be great!
Thanks again

 

its prob your battery but did it crank? did the starter turn over like normal or did it crank slow? you might have to jump your car in really cold weather if possible. next chance you get have your battery tested.

 

Sounds like your battery cannot handle the extreme cold. Either wait till it warms up and try again or it's time for a new battery. The older your battery is, the less it will work in cold temps.
