Has anyone had an ignition switch fail with no warning?
This morning I went to start the UrS (15 degrees) and it turned over fine, but it wouldn't start at all. I tried it 3 separate times and even hit the gas a little, but nothing. I searched the archives and it looks like the ignition switch could be the culprit. However, the threads I was reading mentioned instances where the car wouldn't start and then it would as if the switch was slowly going bad. What do you all think? TIA

Failures I have observed from my switches
1. Switch gets sticky and will not return from the START position. This is very bad because it can result in a burned out starter motor.
2. Car will start and run but the electrical accessories which turn of during starting do not come back on.
3. Car will start intermittently and then finally not start at all. With this failure you can still start the car if you turn the key to the on position and connect the hot side of the solenoid to +12V on the battery.
4. Switch gets stiff and just does not feel right. This is when you should replace the switch with a new OEM switch from the dealer ($38 US). It is worth every penny.

Update: car started fine just now...
20 degrees warmer outside today. We'll see what happens and then I'll try to diagnose. I have 3 other cars to use right now anyway...

Sounds just like what mine did when the switch was going bad
It started with infrequent cranking with no start that I could eventually get the engine to kick over by continuing to cycle the key. I noticed that when ever the car did not start that the dash did not fully light up as normal. If the dash lit up properly the car started.
I'd start with a new switch, cheap, easy and it's going to fail sooner or later anyway so might as well get ahead of it before it leaves you stranded.
