Warranties are the wording and laws the *company* makes -- following the general laws of warranties but ultimately these exist in *their* terms. Warranties exist to cover general, common-sensical failure of the item that couldn't have been forseen by the consumer.
This situation goes beyond the generally-accepted principles of warranty. As a consumer of an item that ranges in price from $6,000-$12,500, in this instance a customer has reasonable cause to expect that the manufacturing process of the playfield was done correctly. Over time, these blisters will peel and potentially ruin the artwork and resale value of this expensive item. At this point in time, there is evidence that blistering leads to noticeable peeling and - in some cases - chips actually coming off of the playfield. Any consumer who has a playfield showing *any* blistering of any sort has cause to suspect the manufacturing process on the entire playfield is flawed. Who knows? Over time, perhaps entire larger chunks may come off due to the fact that the basic process of manufacturing the playfield was flawed.
IMO, the onus shouldn't be on the consumer to take a "wait and see" approach. Since the initial process is proven to be flawed. And since the flawed process *will* result in future damage that goes beyond reasonable historic norms/expectations for the condition of a playfield...any playfield showing any blistering should be subject to recall -- at the manufacturer's expense. Providing a fully populated playfield would be an acceptable outcome for the damaged party.
This reasonable expectation the consumer has that the playfield won't be immediately flawed supersedes a company's own warranty for what they will - or won't - cover. The consumer is entitled to have a general, common-sense expectation that the playfields were manufactured correctly to avoid immediate wear and tear that will potentially adversely impact enjoyment or resale value.
Many here would argue that the playfield is the most important aesthetic aspect of this expensive product and would site collectability and resale concerns. Conversely, in a class action suit, the company named might argue that these are machines meant for routing and they would cite decades of evidence that these are machines of violent impact where the end user can expect wear and tear.
If anything would move forward, it would be a class action suit. To take companies on individually would be absurd and very expensive.
