Hey mproseusa, Perhaps you have the very rare “High G-Force Sensor” option.
As mentioned above, you are right to normally expect an accompanying dash warning light for the specific problem that triggered the master warning panel. Perhaps, you are getting a "liquid level slosh" from a marginal fluid level that turns on - then - off the dash light while the master warning panel's holding function makes sure it has your attention. This could be potentially any fluid on board - low fuel, oil level, radiator reservoir, etc…
One other thought - I have seen the brake pad thickness warning circuits trigger some very strange results as well. This is especially true when the wiring had been poorly spliced, jumpered or hanging loose.
Good Luck, Michael
