Mitsu hq has circulated a service advisory to dealers to consider "any modification to vehicle for possible peripheral relationship to any failure." Verbally, service departments are saying that the total car warranty is voided by addition of any aftermarket modification. Addition of A-M stereo is considered good cause to void engine warranty -- complete car warranty. And that this advisory is being provided in writing to dealers. I obtained a copy. The advisory did not state "directly related" which would make sense, but allowed for warranty cancellation due to "peripherally related" which is anybody's guess. Suggest that this violates the magnusson act, and this practice by Mitsubishi should be investigated. Changing a catback exhaust system seems unrelated to a clutch failure, yet owners are getting warranty rejections for such minor modifications. Thank you
