Then your plane isn't airworthy.

Wrong! They work exactly as designed and as installed by the manufacturer.

You're saying the manufacturer designed your gauges to "bounce around
so much they are useless"?

Even if that were true, it wouldn't make your plane airworthy. If a
tank's fuel gauge doesn't give you information about the tank's fuel
level, then it fails to meet the airworthiness requirement 91.205b9.
