Biz, the point is Nissan hyped a featured that ultimately turned out to void warranties, yet left the disclaimer in fine print. Tell the owners up front about the situation, and more to the point, tell them a transmission replacement is going to cost about $20,000*.

On a related note, last I heard, Chevy is not voiding warranties simply for the use of launch control. The deal there is use versus abuse, and that is pretty much between you and a service manager.

Anyway, I hear ya' about Porsche. The difference there is Porsche tends to promote and support the advertised and marketed capabilities of its vehicles, which IIRC, we have previously discussed.

*Ultimately it comes down to the issue that a $20k transmission *should* be able to reliably hold well more than ~450 lb·ft on a straight launch, even if violently coming off the line. IMO, of course.
