Fair enough. Thanks for the reply, that all makes sense.

I have never run into a situation where my current company tried to limit its warranty in legally interesting ways (and it wouldn't necessarily get to my desk anyway), so I never really had call to dig and find Magnusson-Moss. I suspect that knowledge of that law is probably more top-of-mind for DIYers than for OEM lawyers.

I still think that whether requiring telematics is a "reasonable" condition for a warranty is more complicated than you think, but what you're saying is exactly the counterargument I would make.

And, I hope I've provided some assurance that I am, in fact, a lawyer. Whether I'm a good one is perhaps up for debate. :)
