What strange random events have you had with the LS?

This happened to me again. ABS/Advancetrac went bonkers.
Also my warranty ended yesterday. Wheeeee!

I would guess that one of the wheel sensors is marginal. Cleaning them might correct it.

...switch (could be due to noise from a failing coil). Is this perhaps what you refer to?

Could be why mine beeped.. I just thought about it and it only did it when the coils were on their way out..
