What does it mean when there's a yellow horseshoe with an exclamation point on my Acura MDX dashboard?

The yellow horseshoe icon with an exclamation point on your Acura MDX dashboard typically indicates a problem with the vehicle's tire pressure monitoring system (TPMS). This warning suggests that one or more tires may be under-inflated or that there is a malfunction in the system itself. It’s important to check your tire pressures and inflate them if necessary, and if the light persists, consult your owner's manual or a professional mechanic for further diagnosis.
