PRODUCT HAS BROKEN: PLEASE REPAIR UNDER WARRANTY

Dear Felix

Enclosed, please find [PRODUCT (S), ex. your A45 compressor], which we purchased on [DATE, ex. June 1, 1998] (a copy of the sales receipt is enclosed). After limited use, I’m afraid that it has unexpectedly failed. [STATE NATURE OF MALFUNCTION (S), ex. Although the compressor does begin to operate upon starting, it ceases operation within five minutes and emits mass amounts of smoke.] I therefore request repairs to be made under warranty #[WARRANTY NUMBER], a copy of which is enclosed. If a repair is not possible, I hope that you may send me a replacement.

Please contact me at XXX-XX-XX if there are any concerns.

Regards
Lydia
