It's possible the EPS lamp illuminated solely because the engine
stalled. It'd be difficult for this system to cause a stall.
Whether you should take it in depends not only on how concerned you
are about the car and future problems, but also on the value of your
time and the risk of a no problem found. Choose what's best for you.
I haven't driven the car since posting, but I'm off from work tomorrow
and I'll see how the car performs then. I recall that the car idled
somewhat roughly the last two times I started it after it had been
sitting for a few days. I'll bring it into the dealer if it
misbehaves tomorrow. Thanks for your help -- I appreciate it!
No, it doesn't. The car starts immediately without problem, even on
the first start. I drive it for multiple short trips today, and I
must have started it at least 7 or 8 times in all (that's my usual
driving pattern, combined with city driving, which I know is hard on
cars). No stalling at all. The only thing I noticed is that it seems
to be idling a little roughly at stops. Tachometer is at the usual
point, but the car shakes a little bit.
You've probably ruled out my fuel pump thoughts. If the idle is rough
enough that you think it's obvious, go ahead and take it in. Be sure
to list all the oddities that have occurred, but make special note
that the idle remains rough. If it's doing it when the dealer looks
at it, they should be able to locate the cause. There's a reasonable
likelihood that the rough idle and stalling are due to the same issue.
