Worse on Purpose · Appendix

111 Warranties

The source data behind the Worse on Purpose warranty essay. Every row is a current US warranty document we read, the clause it uses about outside repair and non-branded parts, and a link to the document so you can check it yourself.

read as making coverage depend on who repairs it or whose parts go in

The five groups

Each document was read for what it says about repair by someone other than the manufacturer or its authorized dealer, and about parts not sold by the manufacturer. It was then put in one of five groups by the strictest clause it contains. A document that states the right somewhere and contradicts it elsewhere was graded on the stricter clause.

DocsGroupWhat the document says
9States the rightSays in so many words that outside repair or non-branded parts will not void the warranty.
53Lawful formExcludes only damage "caused by" outside repair or another company's part, and says nothing about whether you may go elsewhere. This is the form the FTC rule permits.
32Reads as a conditionLists outside repair, non-branded parts or any modification as "not covered," or voids the warranty for them, without the words "caused by." A lawyer may call some of these clumsy exclusions. An owner reads them as a condition.
11Forbidden formVoids the warranty on the bare fact of outside repair, a broken seal, or non-branded parts, with no causation requirement. This is the form 16 CFR 700.10(c) names as prohibited.
6SilentSays nothing about outside repair or parts.

By category

The last column adds the forbidden form and the documents that read as a condition. Sample sizes are small in several categories, so the counts are the finding and percentages would overstate them.

Method: brands were chosen for US market share and reader recognition before any document was read. Five documents are retailer-hosted copies of the manufacturer's own warranty and one is a dealer-hosted user manual; each is marked. Three are older revisions the manufacturer still serves (Specialized 2018, Meta 2022, BMW Motorrad MY2021). Grading is a plain reading of the text, not a legal opinion.
