It's a shot in the dark, but it's free and doesn't take much time so
you should try it before going to the dealer.

I remember my dad once asking my mother to hold a large adjustable
wrench he handed her from underneath a car that he was working on. She
set it down on the battery and, with a very spectacular sound and light
show, reset the ecu and fixed the problem. That's probably not the
best way to power cycle a chip, but it worked that day.

Just incase the OP gets any ideas from your anecdotal
semi-suggestion... the worst advice you could give someone is to short
the two battery terminals together ("She set it down on the battery
and, with a very spectacular sound and light show"). The correct way
to drain any charged capacitors in the system is to remove both battery
cables and touch them together. This way you don't shunt the battery
like an fool. It most likely won't cure the OP's problem in any case.

Yes, that's what I tried to say in the earlier post.

DON'T SHORT THE BATTERY! Pull - BOTH - CABLES - and connect those
together. That should be simple, but pay attention as a car battery
won't always forgive an oops.

Just another slight possible.

Perhaps you have some sort of speed warning system? Some cars, I
remember some Buicks particularly, had an audible alarm feature that
would turn on at a preset speed to warn the driver of reaching that
speed.

Yeah, that's likely...

A few questions for Owen:

Who or what owned the car before you?
Was this a fleet vehicle?
On this car, is there a dedicated speaker for the chime or does it come
from the radio?
Is there anything plugged into the ODB port under the steering column?

As someone else mentioned this must be some sort of annoyance based
governor. I would be surprised if this is built into the computer, as
that would probably require replacing at least the ECU ROM, if not the
whole ecu. Perhaps, though, there is a register or jumper in the ECU
for just this purpose.

Let us know; there must be some definite answer.
