Still having having cranking problems after replacing Start/stop button. Have narrowed non-cranking to cool temperature. When ambient temperature gets real warm, ignition turns engine and starts, usually in the afternoons. Thought it was a moisture problem, but more likely heat/cool related.

What is in the ignition system that could be affected by heat/ cool?

 

What year is your ride? 07-08? I ran into couple of ESs have condition just like your's. Check your starter relay and Starter Cut Relay(ST/CUT). They could cause no crank condition. My first run in with this ate my lunch. But, I haven't see that car since then(fixed).

 

2008 ES. Strangely, I changed the fob battery and that "fixed" it for 3 days, then same problem. Changed it again and nothing. Engine will start when I put it in the sun for a few hours if the temperature reaches about 80F or above.
