In what way does the suspension require regular servicing or an online connection to a server to function? That would be the only reason to offer it as an ongoing service cost.
Otherwise, you’re just paying extra for something already in your car, not for an actual service, which would make no sense?
What next, paint ongoing service fees for having wheels? Not even for ensuring they’re regularly replaced, serviced, or repaired, just for the ability to use them at all…
Not enough of the mundane has been preserved throughout human history, it continues to be a big problem for historians. Especially when they only have major - likely very coloured or outright lies - official records of events and cultural touchstones to go on.
Why do you think we get so incredibly excited when we uncover something as mundane as the pricing artwork on an ancient Roman food stall? Because that stuff wasn’t preserved, nobody bothered to record such details, so much is lost because nobody thinks their place in history matters enough to bother saving it.
We’ve reached a point in our development where we now have the ability to preserve snapshots of our civilisation in great detail, with extreme ease. We owe it to ourselves and especially to future generations to do so.
